The Heatwave Economy: Market Emergence, Consumer Adaptation, and Strategic Imperatives in a Warming World

Executive Summary

The increasing frequency, intensity, and duration of extreme heat events are forging a new and complex economic landscape: the “heatwave economy.” This report provides an exhaustive analysis of this emerging reality, defining its characteristics, identifying its key industrial and consumer drivers, and outlining the profound systemic risks and strategic imperatives it presents. The heatwave economy is defined by a fundamental duality: it is simultaneously a significant drag on global productivity and a powerful catalyst for new markets and adaptive spending. While extreme heat inflicts substantial economic damage—estimated at 0.6 percentage points of global GDP in 2023 and a cumulative $16 trillion since 1992—through lost labor productivity, agricultural devastation, and infrastructure failure, it also compels a massive adaptive response. This response is giving rise to a multi-billion-dollar climate adaptation market, projected to exceed USD 100 billion by the early 2030s.

This analysis reveals two primary forces shaping this new economy. The first is a fundamental re-patterning of consumer behavior. Faced with intolerable heat, individuals are altering their daily lives, retreating indoors, rescheduling activities to cooler hours, and making different purchasing decisions. This “Adaptive Wallet” is channeling spending towards immediate coping mechanisms—such as cooling appliances, hydration products, and specialized apparel—and long-term resilience investments, including home retrofits with cool roofs and high-efficiency HVAC systems. These behavioral shifts are creating a decentralized, “in-home” economy while simultaneously exposing a dangerous “adaptation gap,” where the ability to afford cooling and resilience is becoming a key determinant of health and well-being, exacerbating social inequities.

The second force is the industrial and technological response to this new demand. A burgeoning ecosystem of industries is emerging to provide the tools for heat adaptation. This includes the rapidly growing Climate Adaptation Market, with key segments in heat resilience infrastructure, personal adaptation products, and climate risk analytics. Established industrial giants are pivoting to produce more efficient heat pumps and advanced heat-resistant materials, while a vibrant ecosystem of startups is pioneering disruptive technologies like solid-state cooling and AI-driven climate intelligence. The most valuable opportunities lie in “stacked” solutions that integrate passive, active, and intelligent technologies into cohesive systems.

However, this adaptive economy is fraught with systemic risks. The primary solution to heat—air conditioning—creates a perilous feedback loop, straining energy grids to the breaking point and increasing greenhouse gas emissions through reliance on fossil-fuel “peaker plants” and potent HFC refrigerants. This report identifies a core “trilemma” for decision-makers, who must navigate the difficult trade-offs between providing effective cooling, ensuring equitable access, and minimizing environmental emissions. The risk of “maladaptation”—investing in solutions that worsen the problem in the long term—is acute.

For investors, corporations, and policymakers, navigating the heatwave economy requires a sophisticated, systems-level understanding. Investors must pursue a dual-pronged strategy, backing both incumbent leaders in scaled markets and disruptive innovators in emerging technologies, while using equity and maladaptation frameworks as critical ESG risk screens. Corporations must build supply chain resilience, innovate products for a hotter world, and adapt their own operations. Policymakers face the urgent task of breaking the adaptation trilemma through a balanced approach: providing targeted relief for the vulnerable, aggressively updating building codes and regulations, and making massive public investments in grid modernization and urban greening. The heatwave economy is not a future prospect; it is the present reality. The strategic choices made today will determine whether adaptation leads to a more resilient and equitable future or locks in a cycle of escalating costs and crises.

Part I: The Dual Nature of the Heatwave Economy

The emergence of a global economy defined by the imperatives of extreme heat represents one of the most significant structural shifts of the 21st century. It is a phenomenon characterized by a profound and often misunderstood duality. On one hand, heatwaves act as a powerful brake on economic activity, inflicting measurable and growing costs across sectors. On the other, the necessity of human and systemic adaptation is a potent catalyst, creating new industries, driving technological innovation, and reshaping consumer demand. To navigate this new landscape, decision-makers must move beyond a simplistic view of heat as a purely destructive force and instead analyze the complex interplay between economic drag and adaptive response that defines the heatwave economy.

Section 1: Anatomy of a New Economic Reality

The term “heatwave” itself lacks a universally agreed-upon definition, with meteorological agencies using varying thresholds for temperature, duration, and humidity.¹ This definitional ambiguity is mirrored in the economic sphere, where the “heatwave economy” is not a monolithic concept but a complex system of interconnected, and often contradictory, phenomena. It encompasses both the severe, prolonged negative shocks to economic output and the concurrent emergence of new markets and spending patterns driven by the urgent need to adapt.²

This duality can be deceptive. Media reports often highlight short-term spikes in retail sales for items like fans, sun cream, and barbecue supplies, creating a superficial impression of an economic boost.² However, deeper economic analysis reveals that much of this activity is not new growth but rather a “rotation of spending patterns”—for example, pubs gaining market share from restaurants—or household consumption that has been “brought forward” from a later date.² This report dissects this complex duality, separating these illusory gains from the fundamental structural changes reshaping the global economy.

1.1 Quantifying the Drag: Productivity, Agriculture, and Infrastructure

The most immediate and well-documented feature of the heatwave economy is its negative impact on aggregate economic output. Extreme heat is a direct and substantial drag on growth.

• Macroeconomic Costs: The top-line figures are stark. Analyses indicate that an increase in extreme heat and severe drought can reduce a country’s Gross Domestic Product (GDP) by approximately 0.2%.⁵ A 2023 estimate from Allianz calculated that the summer heatwaves across the United States, Southern Europe, and China may have cost 0.6 percentage points of global GDP growth for that year alone. The impact varied significantly by region, ranging from a 0.1 percentage point loss for France to a staggering 1.3 percentage points for China.⁶ The cumulative effect over time is even more alarming. One landmark study estimated that from 1992 to 2013, human-caused increases in heatwave severity cost the global economy approximately $16 trillion.⁷

• Labor Productivity Losses: At the core of this economic drag is the impact of heat on human beings. High temperatures directly impair labor productivity, a fundamental driver of economic value. The body’s capacity to perform physical work dips by about 40% when temperatures reach 32°C (90°F) and plummets by two-thirds at 38°C (100°F).⁶ These losses are most acute in sectors that depend on outdoor or non-air-conditioned manual labor, such as agriculture, construction, manufacturing, and transportation.⁹ The World Economic Forum projects that these productivity losses will amount to $2.4 trillion annually by 2030.¹² In urban centers, the impact can be devastating; a study of twelve major cities found that productivity losses from heat can represent a significant share of local GDP, reaching as high as 8.3% in Dhaka, Bangladesh.¹⁰ This loss of productivity translates directly into reduced income for workers, a burden that falls disproportionately on hourly, informal, and gig-economy laborers who are paid only when they can work.⁹

• Agricultural Devastation: No sector is more vulnerable to the immediate impacts of extreme heat than agriculture. Heatwaves scorch crops, reduce yields, increase water demand, and place immense stress on livestock, leading to reduced milk production, slower growth, and increased mortality.⁹ Research indicates that the economic damages to agriculture from heatwaves are far more severe than previously understood, potentially an order of magnitude larger than what is predicted by models focusing solely on shifts in average temperature. Without significant new adaptation measures, these studies suggest that agricultural output losses from heatwaves could surpass 10% annually by the end of the century.¹⁷ This devastation has a direct knock-on effect for consumers and central banks in the form of higher and more volatile food prices.³

• Infrastructure Strain and Damage: The world’s critical infrastructure—much of it designed and built in a cooler, more stable climate—is now failing under the stress of extreme heat. High temperatures cause steel railway tracks to buckle, asphalt roads to melt, and water lines to burst. Power transformers, essential components of the electrical grid, can overheat and detonate, causing fires and blackouts.¹³ These failures disrupt transportation networks and global supply chains, imposing both direct costs for repair and replacement and vast indirect economic losses from service interruptions and delays.

1.2 The Adaptive Response: Catalyzing New Markets

In direct response to these immense pressures, a new economy is taking shape, one built not on discretionary wants but on the fundamental need for adaptation. This is not driven by a vague “feel-good factor” associated with sunny weather ², but by the imperative to cope and survive in a hotter world. At the most basic level, consumers are purchasing goods to manage heat, from fans and sun cream to portable air conditioners.²

This response, however, extends far beyond simple consumer goods to encompass large-scale capital investment in resilience. The European Central Bank has observed a significant increase in investment and the accumulation of capital stock in hotter regions, specifically for what it terms “adaptation capital”—most notably, air conditioning systems.³ This defensive spending is the seed from which the growth sectors of the heatwave economy are sprouting.

The clearest manifestation of this trend is the emergence of the global Climate Adaptation Market. This market, which includes the technologies, services, and solutions for building resilience to climate impacts, was valued at over USD 22 billion in 2024. It is projected to experience robust growth, with forecasts suggesting it will expand at a compound annual growth rate (CAGR) of approximately 10% to 16%, reaching a value between USD 60 billion and USD 105 billion by the early 2030s.¹⁸ This market represents the industrial backbone of the adaptive side of the heatwave economy.

1.3 The Net Economic Impact: A Ledger of Winners and Losers

The net effect of this dual-natured economy is profoundly uneven, creating a complex ledger of winners and losers at every scale.

Geographically, the burden falls most heavily on the regions least responsible for climate change. Hotter, historically poorer tropical regions suffer the most significant economic losses from extreme heat, while some colder, high-latitude regions in North America and Europe may experience temporary and marginal economic gains from warmer temperatures.⁷

Within national economies, a clear divergence is emerging. Small, geographically concentrated firms are far more vulnerable to sales declines from non-ideal temperatures than large, diversified corporations that can absorb regional shocks.²³ Sectors like agriculture and construction face immense headwinds, while industries providing cooling solutions, specific food and beverage products, and certain indoor leisure services see demand surge during heatwaves.²

This economic disruption is also creating new forms of systemic risk within the financial system. Extreme heat directly impacts the profitability of businesses by reducing productivity and shifting local demand.⁹ This operational stress translates directly into heightened credit risk. One study found that just ten unusual days of extreme heat in a three-month period increases the loan delinquency rate of small and medium-sized enterprises (SMEs) by a remarkable 4.4% of the sample mean.⁹ This risk is most concentrated in the agricultural sector but inevitably spills over into the local retail and service businesses that depend on agricultural income. For banks and other financial institutions, this introduces a new, geographically correlated risk factor that traditional credit models may fail to capture. A severe regional heatwave could trigger a cascade of defaults among small businesses, threatening the stability of local and regional lenders. The increasing volatility and unpredictability of these events further complicate the landscape for central banks, making it more difficult to distinguish between temporary price shocks and permanent inflationary pressures, thereby challenging the efficacy of macroeconomic forecasting and monetary policy.³

A critical, and often overlooked, aspect of this new economy is a deep-seated productivity paradox. The visible spending on adaptation, such as the purchase of air conditioning units, creates an illusion of economic growth and activity. However, this masks a more pernicious underlying trend. The European Central Bank’s research reveals that while investment in this “adaptation capital” is increasing, overall labor productivity in heat-affected regions is simultaneously falling by as much as 10%.³ This occurs because capital spent on adaptation is fundamentally defensive; it is deployed simply to maintain a baseline level of function and comfort in a more hostile environment. This capital is inherently less productive than capital invested in new technologies or processes that generate new value. Furthermore, every dollar spent on an air conditioner is a dollar not spent on a more productive investment, representing a significant opportunity cost. The heatwave economy, therefore, is characterized by a structural shift towards lower-productivity, defensive spending. Societies are compelled to spend more money just to stand still, creating a facade of economic activity while the underlying engine of prosperity—productivity growth—weakens. This is a crucial distinction for investors and policymakers who might otherwise misinterpret adaptation spending as a sign of a robust and healthy economy.

Part II: The Consumer in a Hotter World: Shifting Behaviors and New Demands

The macroeconomic shifts of the heatwave economy are driven by millions of micro-level decisions made by individuals every day. As extreme heat becomes a recurring feature of life, it is fundamentally re-patterning human behavior, altering daily routines, reshaping social interactions, and redirecting consumer spending. Understanding these granular shifts is essential to grasping the demand-side forces that are creating new markets and rendering old business models obsolete.

Section 2: The Re-Patterning of Daily Life

The most profound impact of extreme heat is on the very rhythm of daily existence. People are adapting not just what they do, but when and where they do it, with significant consequences for commerce, community, and health.

2.1 The Great Indoors: A Retreat from Public and Commercial Spaces

Faced with dangerous and uncomfortable heat, the most common adaptation is retreat. Extreme heat significantly curtails the amount of time people spend outside their homes. Data-rich studies show a marked decrease in trips made for leisure, shopping, and socializing as temperatures climb.¹² This is not a marginal effect; research in China quantified that as temperatures rise from a warm 30°C (86°F) to a hot 35°C (95°F), visits to public parks—a cornerstone of urban social life—decline by 5% and 13%, respectively.²⁶

This avoidance behavior has direct and negative consequences for businesses that rely on physical presence. Official statistics from the UK have noted that consumers actively “stayed away from stores” during heatwaves, choosing instead to remain at home.² This trend poses a direct and existential threat to traditional brick-and-mortar retail models that are predicated on foot traffic.

Conversely, this mass retreat is fueling a boom in the “in-home” and on-demand economy. The same study that documented declining park visits also found a significant surge in lunchtime food delivery orders in Chinese cities as temperatures rose.¹² This behavioral shift effectively transfers the burden of heat exposure from the consumer to the gig-economy delivery driver, a dynamic with its own set of social and labor implications. Furthermore, the need for climate-controlled environments is leading to the repurposing of existing spaces. In South Florida, for example, a local outdoor walking group moved its meetups to an indoor shopping mall to escape the summer heat, transforming a commercial space into a de facto community center.¹² This trend suggests a decentralization of economic and social activity, moving away from open, public squares and towards enclosed, private, or semi-private environments.

2.2 The Temporal Shift: Rescheduling Life to Cooler Hours

In addition to changing where they spend their time, consumers are also changing when they conduct their activities. There is a clear and growing trend of rescheduling life to avoid the peak heat of the day. Travel, exercise, and errands are increasingly shifted to the cooler hours of the early morning or late evening.²⁵

This temporal shift has profound implications for the structure of society and commerce. The traditional “9-to-5” workday and the associated patterns of commuting, shopping, and leisure become less practical and more dangerous in a world of extreme midday heat. Research has documented an increase in evening use of parks on very hot days, a logical adaptation that nonetheless carries potential secondary costs, such as sleep disruption and its associated negative health impacts.²⁶

Looking forward, this trend points towards a future where rigid schedules become obsolete. An Ericsson ConsumerLab report suggests a future where consumers use AI-powered planners to optimize their daily activities not around time efficiency, but around variables like real-time energy costs or thermal comfort.²⁸ This would fundamentally change everything from how event tickets are sold (with flexible arrival times) to how public transportation is scheduled, requiring a move towards more dynamic, on-demand systems.

2.3 The Cognitive Load: Heat’s Impact on Decision-Making

The influence of heat extends beyond physical comfort into the realm of cognition. High ambient temperatures do not just make people feel sluggish; they measurably impair their ability to think clearly and make complex decisions. Research published in the Journal of Consumer Psychology and the Journal of Marketing Research has shown that even moderately warm temperatures can deplete cognitive processing ability, leading to purchase decisions that are less thought-out and potentially suboptimal.²⁹

Under this “thermal load,” consumers become more reliant on mental shortcuts, or heuristics. They are more likely to conform to “social proof,” choosing products that are market leaders or preferred by a majority, as this requires less cognitive effort than evaluating alternatives. They also gravitate towards “safer” choices, showing a greater propensity to reject innovative new products that are more difficult to assess.²⁹ For example, in one study, participants in a warm room were more likely to choose a suboptimal, more expensive cell phone plan because they were less able to effectively weigh the risks and benefits of different options.²⁹

These findings have significant strategic implications for marketing, branding, and product development. For established brands with high market share, heatwaves may paradoxically reinforce their dominance as consumers default to familiar, “safe” choices. Conversely, for companies launching a novel or complex product, a heatwave could be the worst possible time for a marketing push, as consumers will have diminished capacity and willingness to engage with new information. Marketing strategies may need to be adapted, simplifying messaging and emphasizing safety and reliability during periods of high heat.

Section 3: The Adaptive Wallet: Evolving Consumer Spending

The behavioral adaptations driven by extreme heat are directly reflected in consumer spending patterns. As people seek to cope with, adapt to, and escape the heat, they are redirecting their household budgets, creating clear market signals that are giving rise to new product categories and fueling growth in specific sectors. This shift in spending can be categorized into three main areas: immediate coping, long-term adaptation, and escape.

3.1 Spending to Cope: The Immediate Needs Market

The most direct and visible economic response to a heatwave is a surge in spending on products and services that offer immediate relief.

• Cooling and Hydration: The demand for personal cooling is exploding. This includes a massive increase in the purchase of air conditioning units and personal fans, a trend so significant that it has added tens of terawatt-hours to summer electricity demand in major markets like China, the US, and India.¹² The market for cold food and beverages also sees a dramatic spike. Projections based on consumer behavior indicate that sales of ice cream and cold beverages can increase by as much as 20% during heatwaves.⁴ This extends to the fast-food sector, where dessert-focused chains like Dairy Queen and even salad-centric restaurants see increased traffic as consumers seek to avoid heating their own kitchens by using stoves and ovens.³⁰ Households experiencing hotter-than-average temperatures have been shown to spend 15% more on ice and 27% more on alcoholic beverages.³⁰

• Apparel and Personal Care: Wardrobes and bathroom cabinets are also being adapted. Retailers see a clear boost in sales of weather-appropriate clothing, such as shorts, sundresses, and lightweight fabrics.² Simultaneously, a new and rapidly growing market for “cooling” personal care products is emerging. This includes a wide array of items formulated to provide a cooling sensation, such as facial gels, body mists, cryotherapy tools like ice globes, and specialized makeup designed to be “summer-proof” and resistant to melting in high heat and humidity.³² Alongside these topical solutions, demand is also rising for products that support the body’s internal response to heat, most notably electrolyte powders and other hydration-focused supplements.³³

3.2 Spending to Adapt: The Home Resilience Market

Beyond immediate coping, consumers are making significant, long-term capital investments to make their homes more resilient and livable in an era of recurring extreme heat. This is creating a sustained boom in the home renovation and improvement sector.

• Active Cooling Upgrades: The installation of new, and particularly more energy-efficient, air conditioning systems is a primary driver of this trend.³⁶ The scale of this shift is immense; one projection suggests that the demand for cooling in India could be eight times higher than current levels by the year 2037.¹¹ This represents a massive market for HVAC manufacturers and installers.

• Passive Cooling Investments: Recognizing the high energy costs of active cooling, homeowners are increasingly investing in passive solutions that reduce a home’s heat absorption in the first place. These renovations are among the highest-return home improvement projects.³⁶ Key investments include the installation of “cool roofs” with light-colored or reflective materials, adding or upgrading insulation (especially in attics), improving weather-stripping around doors and windows, applying heat-control films to glass, and creating external shade through the planting of trees or the installation of awnings.³⁶

This wave of consumer investment in home resilience represents a colossal market opportunity. A World Bank study focusing on India alone identified a potential investment opportunity of $1.6 trillion in the country’s cooling sector by 2040, a figure that includes both active and passive solutions and could create nearly 3.7 million jobs.¹¹

3.3 Spending to Escape: Shifts in Travel and Tourism

Finally, for those with the means, another form of adaptation is to escape the heat altogether. Extreme heat is beginning to reshape travel and tourism patterns. Popular destinations with traditionally hot climates may see a decline in visitor numbers during their peak heat seasons, as tourists seek more comfortable conditions.²⁴ Conversely, cooler regions, whether at higher latitudes or higher altitudes, may experience a surge in tourism.

This can also lead to a rise in domestic tourism, as people opt for shorter trips to local, cooler destinations rather than long-haul international travel to potentially heat-stricken areas.² This trend poses a significant risk to economies that are heavily dependent on tourism in hot regions. These destinations may find themselves needing to offer substantial discounts, shift their peak seasons, or invest heavily in heat-resilient attractions and infrastructure to remain competitive.²⁴

The patterns of consumer adaptation are not uniform across society; they are heavily stratified by income and access to resources, creating and exacerbating a dangerous “adaptation gap.” The ability to adapt is becoming a luxury. For instance, during heatwaves, transportation choices shift dramatically: those with access to air-conditioned private vehicles increase their car usage, while use of public transit, walking, and biking—modes relied upon by lower-income individuals—plummets by nearly 50%.²⁵ This forces the most vulnerable populations to either endure dangerous heat exposure during essential travel or become socially isolated at home. This disparity is stark: studies show that while higher-income individuals significantly reduce their overall trips on extremely hot days, lower-income individuals, often with less flexible employment, show no appreciable drop in travel, indicating they are forced to expose themselves to risk.²⁵

This inequity extends directly into the home. The capacity to invest in critical resilience measures like a new, efficient AC unit, a cool roof, or better insulation is fundamentally a function of wealth.³⁶ This creates a “heat gap,” where wealthier households can afford to create safe, comfortable havens while poorer households are left to suffer in homes that can become dangerously hot.³⁹ This is a vicious cycle: the communities most exposed to urban heat islands due to historical inequities are also the least equipped financially to adapt.⁴¹ This growing divide in adaptive capacity is a critical challenge for public policy and a significant reputational and social risk for corporations, demanding that equity be placed at the center of any strategy for the heatwave economy.

Part III: The Industrial Response: Emerging Markets and Investment Frontiers

The profound shifts in consumer behavior and the escalating physical risks posed by extreme heat are creating powerful demand signals, catalyzing an industrial and technological response. This supply-side reaction is giving rise to a diverse ecosystem of new markets, from large-scale climate adaptation services to specialized personal products. This section details the industries, technologies, and companies that are forming the productive core of the heatwave economy, representing the key investment frontiers in a warming world.

Section 4: The Climate Adaptation Market: A Macro View

The most comprehensive framework for understanding the industrial response is the global climate adaptation market. This overarching sector encompasses all goods and services aimed at increasing resilience to the impacts of climate change, with heat adaptation being a rapidly growing sub-component.

4.1 Market Sizing and Growth Trajectory

The climate adaptation market is transitioning from a niche concern to a major global industry, driven by the undeniable and increasing frequency of extreme weather events, including heatwaves.¹⁸ While estimates from different market research firms vary slightly, they collectively paint a picture of a large and rapidly expanding sector.

As shown in Table 1, market size estimates for 2024 range from approximately USD 22.9 billion to USD 30.1 billion. The growth forecasts are consistently strong, with projected compound annual growth rates (CAGR) in the range of 9.7% to 16.7%. This trajectory suggests the market will reach a valuation between USD 51 billion and USD 105 billion by the early 2030s. This robust growth underscores the scale of investment being mobilized to address climate risks.

Table 1: Global Climate Adaptation Market Forecasts (Consolidated View)

Research Firm	2024 Market Size (USD Billion)	Forecast Year	Forecasted Market Size (USD Billion)	CAGR (%)	Source(s)
Polaris Market Research	22.90	2034	59.84	10.1	¹⁸
MarketsandMarkets	23.2	2030	40.4	9.7	¹⁹
Stellar Market Research	24.30	2032	42.5	7.23	²⁰
Grand View Research	28.17	2030	51.24	10.5	²¹
Fortune Business Insights	30.13	2032	104.93	16.74	²²

A primary driver of this market is government spending. Public agencies, from the municipal to the national level, currently account for the largest share of market activity as they invest in infrastructure resilience and disaster preparedness.¹⁸ In the United States alone, the federal government has committed over USD 50 billion to climate resilience efforts, providing a powerful stimulus for the private sector companies that supply these solutions.¹⁸

Geographically, North America currently represents the largest market, benefiting from significant government investment and the presence of major technology and engineering firms.¹⁸ However, the Asia Pacific region is projected to experience the highest growth rate in the coming years. This is due to the region’s acute vulnerability to a range of climate impacts and a corresponding increase in government and private sector adaptation initiatives.¹⁸

4.2 Key Market Segments

The climate adaptation market is diverse, comprising several key segments that address different aspects of resilience.

• Technology-Based Solutions: This is a leading segment, accounting for over 29% of global revenue in 2023.²¹ It encompasses a wide range of engineered solutions, including advanced cooling systems, the development of more resilient infrastructure materials, and sophisticated water management technologies. This category also often includes technologies that are primarily for climate mitigation but have adaptive co-benefits, such as Bioenergy with Carbon Capture & Storage (BECCS) and Direct Air Capture & Carbon Storage (DACCS).²¹

• Early Climate Warning & Environmental Monitoring: This segment is poised for the highest growth within the market.¹⁸ As climate volatility increases, the demand for proactive risk management is surging. This includes systems that provide more accurate weather forecasting, real-time environmental monitoring (e.g., for air quality or water levels), and the ability to issue timely alerts to governments, businesses, and the public. These solutions empower communities to prepare for and respond to extreme events more effectively.²¹

• Nature-Based and Enhanced Natural Process Solutions: This segment focuses on leveraging natural systems to build resilience. It includes well-established practices like afforestation and reforestation to reduce urban heat and manage stormwater, as well as the restoration of coastal and marine habitats like mangroves to protect against storm surges.¹⁹ It also encompasses enhanced natural processes such as improved land management techniques to prevent soil erosion and ocean fertilization to enhance carbon sequestration.¹⁹ These solutions are increasingly favored for their potential to deliver significant co-benefits for biodiversity, water quality, and human well-being.

Section 5: Hardening the Built Environment: The Heat Resilience Infrastructure Boom

A significant portion of the adaptation economy is focused on retrofitting and redesigning the built environment—our cities, buildings, and infrastructure—to withstand extreme heat. This is creating a boom in technologies and services aimed at creating more resilient and thermally comfortable spaces.

5.1 The Future of Cooling: Beyond the Basic AC Unit

The heating, ventilation, and air conditioning (HVAC) market is a primary and obvious beneficiary of the heatwave economy, with projections suggesting it will become a $367.5 billion industry by 2030.⁴⁴ However, the growth is not in traditional, inefficient systems but in a new generation of smarter, cleaner, and more efficient cooling technologies.

• High-Efficiency HVAC and Heat Pumps: The key trend is a decisive shift towards higher energy efficiency. Heat pumps are a critical technology in this transition. Because they move heat rather than generating it through combustion, they are significantly more efficient for both heating and cooling than traditional furnaces and air conditioners.⁴⁴ Their adoption is being accelerated by substantial government incentives, such as the tax credits and rebates included in the U.S. Inflation Reduction Act. This market is currently led by established industrial giants like Honeywell and Emerson Electric, who are leveraging their scale and distribution networks to meet the surging demand.⁴⁴

• Smart and Adaptive Cooling: The integration of the Internet of Things (IoT) and Artificial Intelligence (AI) is transforming cooling systems from dumb appliances into intelligent, responsive networks. The market for smart thermostats, dominated by brands like Nest and Ecobee, is growing at a 17% CAGR.⁴⁴ These devices learn user preferences and daily routines to optimize temperature settings, saving energy and reducing costs.⁴⁵ More advanced systems use AI to incorporate external data, such as real-time weather forecasts, to proactively adjust cooling and reduce energy consumption. They also use sensors to monitor system components for predictive maintenance, alerting operators to potential failures before they occur, which is critical for reducing downtime in commercial and industrial settings.⁴⁵

• Emerging and Speculative Technologies: At the frontier of innovation, a new suite of cooling technologies is emerging that could disrupt the incumbent vapor-compression cycle:

  • Solid-State Cooling: This category includes technologies that cool without the use of harmful chemical refrigerants. Thermoelectric systems (pioneered by companies like Phononic), magnetocaloric systems (Magnotherm), and elastocaloric systems (Exergyn) use solid-state materials to transfer heat. These technologies are moving from the laboratory to commercial viability, with startups forming strategic partnerships with major HVAC original equipment manufacturers (OEMs) like Carrier and Copeland to scale up production and reduce costs.⁴⁶

  • District Cooling: This approach uses a centralized plant to produce chilled water, which is then distributed to multiple buildings through a network of insulated underground pipes. By centralizing production and leveraging economies of scale, these systems can be 20-30% more efficient than conventional individual building systems. This represents a major opportunity for large-scale infrastructure investment, particularly in dense urban areas.¹¹

  • Solar and Geothermal Cooling: Another key trend is the direct integration of renewable energy into cooling. This includes solar-powered air conditioning systems that reduce reliance on the grid during sunny, peak-demand hours, and advanced geothermal systems that use the stable temperature of the earth for highly efficient heating and cooling.⁴⁵

5.2 Cool Materials and Resilient Architecture

Parallel to the innovation in mechanical cooling systems is a revolution in the materials and design principles used to construct our buildings. The goal is to reduce the need for mechanical cooling in the first place through passive strategies.

• Cool Surfaces: A major and highly effective area of innovation is in materials that reflect solar radiation rather than absorbing it as heat. This includes “cool roofs” and walls that use light-colored paints or specially engineered reflective coatings.¹⁵ These simple interventions can dramatically lower building temperatures and reduce air conditioning costs. The concept is also being extended to urban surfaces like “cool pavements.”

• Advanced Building Materials: A new generation of innovative construction materials is emerging with enhanced thermal properties:

  • Hydroceramics: Developed by the Institute for Advanced Architecture of Catalonia, these are composite materials made of clay panels embedded with a hydrogel that can absorb up to 500 times its weight in water. On hot days, this absorbed water is slowly released through evaporation, providing a passive cooling effect that can reduce interior temperatures by as much as 6°C.⁴⁹

  • Advanced Insulation: Materials like aerogel, an incredibly lightweight synthetic solid that is 99.8% air, offer thermal insulation properties far superior to traditional materials like fiberglass, allowing for thinner and more effective building envelopes.⁵¹

  • Transparent Wood: Researchers have developed a method to make wood transparent, creating a material that is a potential replacement for glass in windows. It is five times stronger and lighter than glass and is a much better thermal insulator, reducing heat transfer.⁴⁹

  • Heat-Resistant Polymers: In a hotter world, materials used in everything from building components to automotive parts and electronics must be able to withstand higher temperatures without degrading. This is driving demand for high-performance polymers like PEEK, Ultramid, and Nomex from specialized chemical companies such as BASF, DuPont, and Victrex.⁵³

5.3 Urban Greening as Critical Infrastructure

There is a growing recognition that nature itself can be a powerful and cost-effective technology for heat resilience. Green infrastructure is now being viewed not merely as an aesthetic amenity but as a critical component of urban climate adaptation.

• Mechanisms of Cooling: Trees, parks, and other forms of vegetation cool urban environments through two primary mechanisms: direct shading of buildings and surfaces, and evapotranspiration, a process where plants release water vapor into the air, which has a cooling effect.¹⁵ Green roofs, which involve planting vegetation on rooftops, are particularly effective at reducing the cooling demands of the buildings beneath them.⁵⁵ The economic value of this can be substantial; a study of the urban tree canopy in Louisville, Kentucky, found that it provided over $389 million in annual benefits, including energy savings from temperature moderation.⁵⁴

• Effectiveness and Implementation: A global meta-analysis of green infrastructure projects found that large-scale installations like botanical gardens and wetlands provided the most significant air cooling, but that smaller, more distributed interventions like green walls and street trees were also highly effective.⁵⁶ Cities are beginning to integrate these solutions into their capital improvement plans. Raleigh, North Carolina, for example, is implementing a program to build green stormwater infrastructure (GSI) combined with strategic tree planting in historically underserved and vulnerable communities. This approach provides multiple co-benefits, simultaneously managing stormwater runoff, improving water quality, and reducing the local urban heat island effect.⁵⁷ This serves as a model for multi-benefit public investment in the heatwave economy.

The most advanced and valuable opportunities in the heat resilience market will not come from single-point solutions, but from the intelligent integration of multiple technologies into “stacked” or “hybrid” systems. While individual innovations in HVAC, materials, and urban greening are important, their true potential is unlocked when they work in concert. For example, a homeowner might combine a passive solution (a cool roof) with an efficient active solution (a heat pump) and an intelligent control system (a smart thermostat) to achieve maximum resilience and energy savings.

At a more sophisticated level, we see true technological integration. The company Phononic has developed a hybrid HVAC system that uses a traditional compressor for initial, less-energy-intensive chilling of outside air, and then employs its own advanced thermoelectric technology for the final, more efficient cooling to the desired indoor temperature. This stacked approach has been shown to cut a building’s energy consumption by nearly 50%.⁴⁷ Similarly, the most advanced smart AC systems are hybrids that integrate AI-driven software (using weather forecast data), physical hardware (compressors and sensors), and user-facing controls into a single, optimized system.⁴⁵ The future of the heat resilience market, therefore, belongs to companies and investors who can think beyond selling a single product and instead design and deliver these integrated, multi-layered systems that provide holistic solutions.

Section 6: Personal and Wearable Adaptation

While infrastructure and buildings are being hardened against heat, a parallel market is emerging for products that allow individuals to adapt on a personal, wearable level. This market spans from next-generation textiles to a new category of wellness and personal care products designed specifically for thermal comfort.

6.1 The Next Generation of Apparel: Smart and Functional Textiles

The apparel industry is responding to the demand for heat-adaptive clothing with a new class of “functional textiles” engineered for thermoregulation.⁵⁸

• Passive Cooling Fabrics: A leading innovation in this space comes from companies like Outlast, which utilizes a technology originally developed for NASA. They embed microencapsulated, phase-change natural wax into fabrics. This material has the ability to absorb excess body heat when the wearer is hot and store it. When the body’s temperature falls, the material releases the stored heat back, creating a dynamic thermal buffer. This proactive temperature management has been shown in independent tests to reduce the onset of sweating by up to 48%. These textiles are being incorporated into a wide range of products, including performance apparel, everyday clothing, shoes, and bedding.⁵⁹

• Active/Smart Textiles: Graphene, a one-atom-thick layer of carbon, is enabling a technological leap into active, electronically controlled textiles. Scientists at The University of Manchester’s National Graphene Institute have developed prototype garments that integrate graphene layers into the fabric. By applying a small electrical charge, the infrared emissivity of the graphene can be tuned, allowing the fabric to either block and retain body heat (like an emergency blanket) or become transparent to infrared radiation, allowing heat to escape and cool the wearer. This technology, which can be integrated into common materials like cotton, effectively allows a piece of clothing to have a dynamic, controllable thermal signature.⁶⁰

• Thermo-Adaptive Materials: The U.S. government’s Advanced Research Projects Agency-Energy (ARPA-E) is funding the development of even more advanced “thermally adaptive” materials. These are engineered to physically change their structure—for instance, becoming thicker or thinner—in direct response to changes in ambient temperature. This change in structure alters the material’s insulation value. Critically, this is a passive physical response that requires no electricity, sensors, or user input, offering the potential for garments that automatically adapt to keep the wearer comfortable across a broader range of temperatures.⁶¹

6.2 The Wellness and Personal Care Response

The global wellness industry, a large and resilient market that consumers are reluctant to cut spending on even in economic downturns ⁶², is rapidly innovating to address the challenges of extreme heat.

• Topical Cooling and Cryotherapy: A burgeoning category of personal care products is being marketed on its ability to provide an immediate cooling sensation. This includes facial moisturizers, toners, shower gels, and foot sprays that use ingredients like menthol, aloe vera, and peppermint oil to create a feeling of coolness on the skin.³² This trend also extends to at-home “cryotherapy” tools, such as freezable glass or steel “ice globes” and beaded gel face masks that can be kept in the refrigerator or freezer and used to reduce skin temperature, depuff, and soothe irritation.³²

• Heat-Proof Cosmetics: The beauty industry is formulating products specifically designed to perform in hot and humid conditions. This includes lightweight, non-comedogenic foundations, oil-free and mattifying primers to control shine, and long-wearing setting sprays that “lock” makeup in place and prevent it from melting or sliding off due to heat and sweat.³⁴

• Internal Wellness and Hydration: Recognizing that adaptation is both an external and internal process, there is a growing market for ingestible products that support the body’s ability to cope with heat. A key category is electrolyte powders and drinks, which are designed to replenish the essential minerals like sodium and potassium that are lost through increased sweating. This focus on enhanced hydration is becoming a core tenet of wellness routines in hotter climates.³³

The industrial response to the heatwave economy is unfolding along two distinct but interconnected timelines, creating a complex and dynamic investment landscape. On one track, established industrial incumbents like Honeywell, Emerson, BASF, and DuPont are leveraging their immense scale, R&D budgets, and market dominance to lead in large, incremental markets. They are adapting their existing product portfolios to meet the new demand for more efficient heat pumps, more durable heat-resistant polymers, and smarter building controls.⁴⁴ Their strategy is one of evolution and scaling proven technologies.

On a parallel track, a vibrant ecosystem of nimble startups and innovators is pursuing disruptive, higher-risk, but potentially transformative technologies. This is where the revolutionary breakthroughs are happening, in areas like solid-state cooling (with companies like Phononic, Magnotherm, and Anzen Walls), AI-driven materials discovery (Matnex), and novel passive cooling building materials (Respyre).⁴⁶ Their strategy is one of revolution, aiming to create entirely new markets.

The most critical dynamic for investors to watch is the increasing interaction between these two tracks. Large OEMs are beginning to de-risk their future R&D pipelines by investing in, partnering with, or acquiring these promising startups. For example, HVAC giant Carrier has invested in elastocaloric startup Exergyn, while its competitor Copeland has backed thermoacoustic heat pump innovator BlueHeart Energy.⁴⁶ This creates a clear pathway for investors: one can pursue a strategy of investing in the predictable, large-scale growth of the incumbents, or a venture-capital style strategy of backing the disruptive startups. A hybrid approach, focused on identifying the startups whose technology is most likely to be validated and acquired by an industrial giant, may offer the most attractive risk-reward profile, as it combines the potential for high growth with a clear and logical exit path.

Part IV: Systemic Risks and Strategic Challenges

While the heatwave economy is creating new avenues for growth and innovation, it is also fraught with profound systemic risks and negative externalities. The very solutions being deployed to adapt to heat can, if not managed carefully, create dangerous feedback loops that exacerbate the underlying climate crisis, deepen social inequalities, and lock societies into unsustainable pathways. Navigating these challenges is the central strategic task for all actors in this new economic landscape.

Section 7: The Energy-Cooling Nexus: A Grid Under Strain

The most immediate and dangerous systemic risk arises from the relationship between cooling and energy. The primary solution to extreme heat—mechanical air conditioning—is placing an unsustainable burden on the world’s electrical grids, creating a vicious cycle that threatens both energy security and climate goals.

7.1 The Vicious Cycle of Cooling Demand

The global demand for space cooling is the fastest-growing use of energy in buildings. Projections indicate that the energy needed for cooling will triple worldwide by 2050, with an estimated ten new air conditioning units being sold every second for the next three decades.⁶³ During heatwaves, this baseline growth is amplified by massive demand spikes, as millions of AC units are turned on simultaneously and run for longer periods at higher settings.³⁷

This surge in demand places an immense strain on electrical grids, many of which are aging and were not designed to handle such extreme peak loads.³⁷ In recent years, this has pushed major grids, such as the one in California, to the very brink of collapse, forcing grid operators to issue emergency alerts and prepare for rolling blackouts to prevent catastrophic failure.⁶³ The problem is compounded by the fact that heat itself degrades the physical infrastructure of the grid. High ambient temperatures cause overhead transmission lines to heat up, increase their electrical resistance, and sag, which reduces their power-carrying capacity and increases the risk of contact with vegetation, which can cause wildfires. At the same time, critical components like transformers can overheat and fail under sustained high loads.⁶⁶ Even renewable energy sources are not immune; the efficiency of solar panels, for example, declines at very high temperatures, reducing power generation precisely when it is needed most.⁶⁶

7.2 The Emissions Blowback: Refrigerants and Peaker Plants

This vicious cycle has a critical climate dimension. The two core components of our current cooling paradigm—chemical refrigerants and the electricity used to power them—are significant sources of greenhouse gas emissions.

• Refrigerant Impact: For decades, the chemicals used as refrigerants in cooling systems have posed a threat to the atmosphere. Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) were phased out under the Montreal Protocol for their role in depleting the ozone layer.⁶⁷ Their primary replacement, hydrofluorocarbons (HFCs), do not harm the ozone layer but are incredibly potent greenhouse gases. Many HFCs have a Global Warming Potential (GWP) that is thousands of times greater than that of carbon dioxide (
  CO2​).⁶⁸ For example, one kilogram of the common refrigerant R410a has the same warming impact as two metric tons of
  CO2​, equivalent to driving an average car for 10,000 kilometers.⁶⁸ With an estimated 90% of all refrigerant emissions occurring at a product’s end of life due to improper disposal, the rapidly growing global stock of air conditioners and refrigerators represents a massive, ticking climate bomb.⁶⁹

• Peaker Plant Reliance: The strain that cooling demand places on the grid also leads to increased emissions. To meet the sharp spikes in electricity demand on hot afternoons and evenings, grid operators often have to turn to “peaker plants.” These are power plants that sit idle most of the time and are fired up only to meet peak demand. They are typically the oldest, least efficient, and highest-emitting fossil fuel plants in the system, often running on natural gas or oil.⁶³ This means that the very act of turning on an air conditioner to escape the heat directly contributes to the carbon emissions that are causing the heatwaves to become more frequent and intense in the first place.

7.3 The Market for Grid Resilience

This escalating crisis is, in turn, creating a significant market for technologies and services designed to enhance grid flexibility and mitigate peak demand.

• Energy Storage: A critical solution is large-scale energy storage. This allows energy generated from intermittent renewable sources, like solar power produced during the middle of the day, to be stored and then discharged onto the grid during the late afternoon and evening peak demand hours.⁶³ While lithium-ion batteries are the most well-known form of grid storage, thermal energy storage is emerging as a highly cost-efficient and targeted solution for cooling. These systems use cheaper, off-peak electricity at night to create large quantities of ice, which is then used during the day to cool buildings, dramatically reducing their electricity demand during peak hours.⁶³

• Demand-Response and Efficiency: Another key area is in technologies that can actively manage and reduce demand. Smart thermostats and intelligent building management systems can be programmed or remotely controlled by utilities to automatically reduce AC consumption slightly during critical peak periods, a practice known as demand-response.⁴⁵ On a broader scale, policies and incentives that encourage the replacement of old, inefficient AC units with modern, high-efficiency models or heat pumps directly reduce the amount of electricity each household draws from the grid, lessening the overall strain.³⁷

Section 8: The “Heat Gap”: Social Equity in the Heatwave Economy

The costs and benefits of the heatwave economy are not distributed evenly. Extreme heat and the ability to adapt to it are profoundly shaped by income, race, and geography, creating a “heat gap” that exacerbates existing social inequalities and poses a significant ethical and political challenge.

8.1 The Unequal Burden of Exposure

Heat risk is not an equal opportunity threat. Within the same city, some communities experience dangerously higher temperatures than others. This is often a direct legacy of historical discriminatory practices like “redlining,” where neighborhoods, typically those with residents of color, were systematically denied investment. Today, these neighborhoods often have less green space and tree canopy, and a higher concentration of heat-absorbing surfaces like asphalt and dark roofs. This creates “urban heat islands” where temperatures can be significantly higher than in wealthier, greener parts of the city.³⁹

This unequal exposure is compounded by occupational and health disparities. People of color and low-income individuals are disproportionately represented in heat-exposed industries like agriculture, construction, and manufacturing, where they suffer greater health risks and more significant productivity and wage losses.⁴² The health impacts are also racially disparate; in the United States, for example, American Indian/Alaska Native and Black populations experience higher rates of heat-related mortality than White populations.⁷³

8.2 Unequal Access to Adaptation: The Cooling Divide

The ability to adapt to heat is a primary determinant of health and safety, and this ability is highly unequal. Access to cooling, particularly residential air conditioning, is a stark dividing line. Low-income households, which disproportionately include communities of color, are less likely to have air conditioning and often face affordability challenges in paying the higher electricity bills required to run it, even if they do.⁴¹ This “cooling divide” or “heat gap” means that the most vulnerable populations are often left to endure dangerous indoor temperatures.³⁹

This inequity extends to mobility and infrastructure. As noted previously, those with access to private, air-conditioned vehicles can travel in comfort, while those who rely on walking or public transportation are forced to expose themselves to extreme heat during essential travel.²⁵ The vulnerability of the electrical grid further amplifies this inequity. In the event of grid strain, public safety power shut-offs are often implemented, and these can disproportionately affect low-income neighborhoods, cutting off their primary means of cooling and putting residents’ health at severe risk.⁴² The following table provides a structured overview of these intersecting vulnerabilities.

Table 2: Social Vulnerability Matrix for Extreme Heat

Vulnerable Group	Housing Quality / AC Access	Occupational Exposure	Mobility / Transit Exposure	Health Outcomes	Economic Impact / Wage Loss
Low-Income Households	Lower-quality housing, less insulation. Less likely to own AC; high energy bills are a barrier to use.⁴¹	Overrepresented in some exposed sectors.	Higher reliance on walking and public transit, which offer less protection from heat.²⁵	Higher risk of heat-related illness and death due to lack of cooling access.⁷³	Energy costs consume a higher portion of income; less flexible work schedules.²⁵
Outdoor Workers	Varies by income.	Direct, prolonged exposure in sectors like agriculture, construction, delivery.⁴²	Commuting can add to heat exposure.	Top cause of exertion-related occupational injuries and deaths.⁷³	Direct productivity losses; loss of income for hourly workers when work is stopped.¹⁰
Elderly	Often live in older, less-insulated homes; may be socially isolated and unable to seek help.⁴¹	Less applicable, but home health aides may be exposed.	Mobility challenges can make travel to cooling centers difficult.³⁹	Highly vulnerable to heat stroke and exacerbation of preexisting conditions like heart disease.⁴¹	Often on fixed incomes, making high energy bills a significant burden.⁴¹
Communities of Color	More likely to live in “urban heat islands” due to historical redlining; lower rates of tree canopy.⁴¹	Overrepresented in heat-exposed industries like farming and construction.⁴²	Disproportionately reliant on public transit in many urban areas.²⁵	Higher rates of heat-related mortality for AIAN and Black populations.⁷³	Suffer greater aggregate wage losses due to overrepresentation in exposed sectors.⁴²
Incarcerated Populations	Often housed in facilities without air conditioning, leading to dangerously high indoor temperatures.⁷³	N/A	N/A	Documented increases in mortality during heatwaves in prisons without AC.⁷³	N/A

Section 9: The Peril of Maladaptation

Perhaps the most insidious risk in the heatwave economy is that of “maladaptation.” This occurs when an action taken with the intention of adapting to a climate risk inadvertently increases vulnerability, either for a different group of people, in a different location, or at a future point in time.⁷⁴ Maladaptive strategies can create long-term “lock-ins,” embedding societies in unsustainable pathways that are difficult and extremely costly to reverse.⁷⁵

9.1 Identifying Maladaptive Pathways

The heatwave economy is rife with potential for maladaptation.

• The Air Conditioning Lock-in: The most prominent example is the over-reliance on energy-intensive, HFC-refrigerant-based air conditioning as the default solution to heat. While an individual AC unit effectively cools an indoor space, the mass adoption of this technology without systemic changes leads to a cascade of negative consequences. It dramatically increases electricity demand, which strains the grid and leads to greater reliance on high-emitting peaker plants. It also increases the atmospheric stock of potent HFC greenhouse gases. In this way, the solution to the immediate problem of heat directly exacerbates the long-term problem of climate change.⁷⁵

• Water Mismanagement: Certain greening strategies can be maladaptive if not implemented with a systems perspective. For example, large-scale tree planting initiatives that use water-intensive, non-native species in drought-prone regions can provide shade but may worsen local water scarcity, increasing vulnerability to a different climate hazard.⁴⁸

• Infrastructure Inflexibility: The construction of “hard” infrastructure designed to solve one problem can create others. A classic example from coastal adaptation is a sea wall that protects one community but accelerates erosion down the coast.⁷⁵ In the context of heat, building infrastructure that is designed only for today’s climate, without accounting for the more intense heatwaves of the future, is a form of maladaptation that wastes capital and guarantees the need for more costly retrofits later.

9.2 Framework for Avoiding Maladaptation

Avoiding these pitfalls requires a more sophisticated, systems-thinking approach to adaptation planning. Key principles include:

• Prioritizing Passive Solutions: The first line of defense against heat should always be passive measures that do not consume energy. This includes strategies like planting trees for shade, using reflective materials on roofs, and designing buildings for better natural ventilation. These solutions should be maximized before resorting to energy-intensive active cooling.⁴⁸

• Holistic Cost-Benefit Analysis: When evaluating adaptation options, the analysis must go beyond direct project costs and benefits. It must account for the full range of ancillary impacts, including positive co-benefits (e.g., improved air quality from urban greening) and potential negative externalities or maladaptive outcomes (e.g., increased grid strain from AC).⁷⁵

• Flexible and Adaptive Planning: Given the uncertainty of future climate projections, policies should favor flexible and adaptable strategies over rigid, large-scale projects that create lock-in. This might mean pursuing a sequence of smaller, more adaptable interventions that can be adjusted over time as conditions change, rather than betting everything on a single, massive infrastructure project.⁴⁸

The strategic challenge of the heatwave economy can be understood as a difficult “trilemma.” Policymakers, businesses, and communities are forced to navigate the inherent trade-offs between three competing goals: Efficacy (providing effective and immediate cooling), Equity (ensuring that cooling is accessible to all, especially the most vulnerable), and Emissions (minimizing the environmental impact of cooling solutions).

The nature of this trilemma is stark. The most immediately effective and widely available cooling technology is the traditional air conditioner.³⁷ However, this solution scores very poorly on the

emissions metric, due to both its high electricity consumption and its reliance on HFC refrigerants.⁶³ Attempting to make this high-emission solution

equitable through broad subsidies or mandates would lead to its mass deployment, which would massively amplify its negative environmental externalities and push already-strained energy grids past the breaking point—a clear example of large-scale maladaptation.

Conversely, solutions that are more environmentally sustainable, such as passive cooling retrofits (cool roofs, better insulation) or urban greening, have much lower emissions. However, they can be less effective during the most extreme heat events and often have high upfront capital costs. This high cost makes them inherently inequitable, as they are often out of reach for low-income households and under-resourced communities without significant public investment.³⁶

There is no simple solution to this trilemma. It represents the core strategic challenge of the heatwave economy. Navigating it successfully requires a balanced and phased approach. In the short term, it may require targeted deployment of efficient active cooling for the most vulnerable populations to save lives. In the long term, it demands aggressive public and private investment in the systemic solutions that can break the trade-offs: massive scaling of passive cooling through updated building codes, large-scale urban greening programs, and a fundamental modernization of the energy grid to run on clean, reliable power.

Part V: Strategic Outlook and Recommendations

The heatwave economy is not a temporary anomaly but a permanent and growing feature of the global economic landscape. Its trajectory will be defined by the accelerating impacts of climate change and the strategic responses of investors, corporations, and governments. This final section synthesizes the preceding analysis to provide a forward-looking perspective and a set of actionable recommendations for navigating the opportunities and risks of this new reality.

Section 10: The Long-Term Trajectory of the Heatwave Economy

The economic, social, and industrial trends identified in this report are poised to intensify significantly in the coming decades. As global temperatures continue to rise, the pressures driving the heatwave economy will grow stronger, and its consequences will become more severe.

10.1 Future Scenarios: Economic Impacts in a 2°C+ World

The economic damages from heat are on an exponential curve. Without aggressive adaptation, the human and financial costs will become staggering. In a developed, temperate country like the United Kingdom, heat-related deaths are projected to increase by 580% by the 2050s compared to a recent baseline.⁷⁶ The impact on global food systems will be even more dramatic. End-of-century agricultural damages from heatwaves are now projected to be 5 to 10 times larger than what is predicted by older economic models that only accounted for shifts in average temperature.¹⁷

Furthermore, the interconnected nature of the global economy will amplify these impacts through supply chain disruptions. Research modeling future scenarios indicates that the share of total GDP losses attributable to indirect, cascading effects through supply chains will grow dramatically with warming. At 1.5°C of warming, supply chain disruptions are projected to account for 13% of total economic losses from heat stress; at 3°C, that figure rises to 25%; and under a catastrophic 7°C warming scenario, it would reach 38%.⁷⁷ This highlights the increasing fragility of globalized production systems and demonstrates that no economy, regardless of its location, will be immune to the financial consequences of extreme heat.

10.2 Identifying Key Corporate Players and Emerging Innovators

This evolving economic landscape will be shaped by a diverse ecosystem of corporate actors.

• Incumbents: Established industrial giants are well-positioned to capture large segments of the adaptation market by leveraging their scale, brand recognition, and distribution channels. Key players include:

  • HVAC and Building Controls Leaders: Companies like Honeywell and Emerson Electric are at the forefront of the shift towards high-efficiency heat pumps and smart, IoT-enabled building management systems.⁴⁴

  • Materials Science and Chemical Giants: Firms such as BASF, DuPont, Solvay, and Victrex are seeing growing demand for their portfolios of advanced, heat-resistant polymers and materials used in construction, automotive, and electronics.⁵³

  • Technology and Engineering Conglomerates: Major technology firms like IBM and energy service companies like Enel X are providing the critical data analytics, AI, and smart grid solutions needed for climate risk assessment and energy management.¹⁸

• Disruptors: A vibrant ecosystem of startups and smaller innovators is driving the technological frontier. These companies are often focused on more disruptive, high-risk technologies that could redefine entire markets. Key areas of innovation include:

  • Solid-State Cooling: A new generation of companies like Phononic (thermoelectric), Magnotherm (magnetocaloric), and Exergyn (elastocaloric) are pioneering refrigerant-free cooling technologies that promise higher efficiency and lower environmental impact.⁴⁶

  • Advanced Materials and AI: Startups are using artificial intelligence and machine learning to accelerate the discovery and development of new materials with superior thermal properties.

• The Semiconductor Ecosystem: An often-overlooked but critical enabler of the heatwave economy is the sector dedicated to thermal management for advanced electronics. The very technologies used to model climate change and power the AI in smart systems generate immense amounts of heat. As data centers, high-performance computing, and AI proliferate, the need for sophisticated cooling solutions for semiconductor packages becomes paramount. This creates a significant market for specialized firms like Boyd Corporation, JetCool Technologies, and KULR Technology Group, which provide everything from advanced thermal interface materials (TIMs) to liquid cooling systems for high-power chips.⁷⁹

Section 11: Actionable Intelligence and Recommendations

Navigating the complexities of the heatwave economy requires a proactive and nuanced strategy. The following recommendations are targeted at the key decision-makers who will shape the response to this global challenge.

11.1 For Investors

• Adopt a Two-Pronged Investment Thesis: The industrial landscape of the heatwave economy is bifurcated. A successful investment strategy should reflect this. Portfolios should be diversified to include both: 1) investments in established, cash-flow positive incumbents that are leading the large-scale deployment of proven technologies like heat pumps, grid modernization equipment, and advanced polymers; and 2) venture-style investments in the high-growth, higher-risk startups that are pioneering disruptive technologies in areas like solid-state cooling and AI-driven climate analytics. Particular attention should be paid to startups forming partnerships with industrial giants, as this can signal technological validation and a clear potential exit path.

• Integrate Sophisticated ESG Risk Frameworks: The social and environmental risks of the heatwave economy are material financial risks. Investors should move beyond simple ESG checklists and use more sophisticated analytical tools. The Social Vulnerability Matrix presented in this report (Table 2) can serve as a framework for assessing a company’s exposure to the “heat gap” and the equity dimensions of its products and operations. Similarly, evaluating companies against the principles for avoiding maladaptation—such as a preference for passive over active solutions—can identify firms with more sustainable and resilient long-term business models. Companies that develop low-emission solutions or provide equitable access to cooling will possess a stronger social license to operate and are likely to outperform in a world increasingly focused on climate justice.

• Focus on Key Growth Sectors: Based on the analysis, capital should be directed towards several key growth themes within the broader heatwave economy:

  • Grid Modernization & Energy Storage: Technologies and services that enhance grid flexibility, including battery and thermal energy storage, smart grid software, and advanced transmission components.

  • High-Efficiency & Smart Cooling Systems: Companies leading the transition to heat pumps, IoT-enabled HVAC, and next-generation cooling technologies.

  • Advanced Building Materials & Passive Cooling: Firms developing and manufacturing cool roof coatings, advanced insulation, and other materials that reduce the need for mechanical cooling.

  • Water Management & Technology: Solutions for water conservation, recycling, and efficient irrigation, as heat exacerbates water scarcity.

  • Climate Risk Analytics & Early Warning Systems: Platforms that use data and AI to model physical climate risk, providing essential intelligence to insurers, corporations, and governments.

11.2 For Corporations

• Build Proactive Supply Chain Resilience: The era of assuming stable operating conditions is over. Corporations must conduct thorough heat stress vulnerability assessments of their entire supply chains, looking beyond tier-1 suppliers to identify risks in raw material sourcing, transportation corridors, and manufacturing hubs located in heat-prone regions. Strategies must shift from “just-in-time” to “just-in-case,” involving diversification of sourcing, increased inventory of critical components, and investment in more resilient logistics.

• Innovate for a Hotter World: Product development strategies must be reoriented to meet the demands of the adaptive consumer. This means embedding principles of efficiency, intelligence, and resilience into product design. The “heat-proof” cosmetic, the “grid-friendly” appliance that minimizes peak-hour energy use, and building materials with passive cooling properties are no longer niche products but massive market opportunities.

• Adapt Internal Operations: Corporations must apply the principles of heat adaptation to their own operations and workforce. This includes re-evaluating working hours and mandating cooling and hydration breaks for employees in heat-exposed roles to protect their health and maintain productivity. It also involves investing in cooling and energy efficiency measures for all facilities, not just for comfort, but as a core business continuity strategy to reduce operational risk and exposure to volatile peak electricity pricing.

11.3 For Policymakers

• Navigate the Adaptation Trilemma with Balanced Policies: The central policy challenge is to break the trilemma of efficacy, equity, and emissions. This requires a multi-layered policy approach that avoids the trap of maladaptive, one-size-fits-all solutions. A balanced strategy would involve: 1) targeted, means-tested subsidies or programs to provide high-efficiency active cooling (e.g., portable heat pumps) to the most medically and financially vulnerable populations as a short-term public health imperative; combined with 2) aggressive, universal policies that drive long-term systemic change, such as stringent updates to building codes that mandate high levels of energy efficiency and passive cooling measures for all new construction and major renovations.

• Modernize Regulation for a New Climate Reality: Regulatory frameworks must be updated to reflect the urgency of the heat crisis. This includes establishing statutory maximum working temperatures for both outdoor and indoor environments to protect workers. Permitting processes for critical adaptation infrastructure, such as grid modernization projects, renewable energy installations, and district cooling systems, should be streamlined. Governments must also accelerate the phase-down of HFC refrigerants while actively supporting the market for sustainable, low-GWP alternatives through standards and incentives.

• Invest in Public Goods and Equitable Planning: Governments have a critical role to play in providing the public goods that individual actors cannot. This includes funding and operating networks of public cooling centers, implementing large-scale urban greening programs, and developing robust, publicly accessible heat-health early warning systems. Crucially, all public investment and urban planning must be conducted through an equity lens, explicitly prioritizing the neighborhoods and communities that are most vulnerable to the urban heat island effect and have the fewest resources to adapt. This requires deep and authentic community engagement to ensure that solutions are not just imposed, but are co-designed to meet the real needs of residents.
