The Heat Budget Has a Blind Spot

There is now enough money in sustainable technology to make the old complaint—that nobody will fund the transition—sound dated. Bain & Company says private firms and governments put $17 trillion into sustainable technologies over the past decade, including $2.4 trillion in 2025. Yet 90% of that investment went to green energy, buildings, and mobility. The money is moving; it is simply moving through a rather narrow set of doors. Bain’s release is here.

That matters for a heat-and-fire age because daily resilience is not just a solar panel, an electric vehicle, or a handsome rendering of a net-zero office. It is also water, materials, land management, agricultural systems, cooling, maintenance, and the unglamorous institutional capacity to notice a bad week before it becomes a bad season. Bain says agriculture, manufacturing and materials, and natural capital received less than 10% of the investment even though, by its accounting, they produce roughly 37% of global greenhouse-gas emissions. This is not proof that every neglected dollar would have been wisely spent. It is evidence of a portfolio with conspicuous holes.

The same report says only solar, batteries, and EVs beat the deployment forecasts made a decade earlier; 29 of 37 tracked technologies missed theirs. That is less a verdict on technology than a reminder that machinery requires policy, behavior, permitting, skilled labor, supply chains, and someone responsible after the ribbon-cutting. Heat waves and fire conditions are exquisitely uninterested in whether a solution looked excellent in a 2035 slide deck. Bain itself framed the summer’s record heat as a warning that more is required—an assessment worth reading alongside the release’s substantial methodological limits, since it is a company-issued report rather than independent reporting. The underlying claims and caveats are described in the release.

For households and local governments, climate risk does not arrive as an abstract emissions share. It arrives as a cooling bill, a canceled shift, a smoke-filter purchase, a road repair, an insurance renewal, or no renewal at all. Bain says disaster losses are rising 5–7% annually and that the gap between total losses and insured losses remains large. Its release does not break those figures out for the United States, wildfire, or any individual hazard. But the underlying political arithmetic is familiar: when risk is underinsured, costs do not vanish. They migrate—to families, municipal budgets, ratepayers, charities, and federal disaster systems. Bain’s report summary is here.

This is why resilience should not be confused with a consumer preference, however earnest the consumer. Bain’s survey of 7,500 people in five countries found that 85% reported concern about environmental sustainability and that respondents said they would pay an average 18% premium for a sustainable product. Those findings may indicate appetite, but a family deciding between rent and an air conditioner is not conducting a stated-preference survey. Nor can an individual shopper harden a substation, redesign a drainage system, keep a clinic cool, or fund the vegetation work and emergency planning that reduce fire danger.

The public question, then, is not whether people care. The report suggests many do. The question is whether resilience is treated as a shared service before a disaster, rather than as a private purchase afterward. In American terms, that means paying attention to the people who work outdoors, residents without reliable cooling, communities at the wildland-urban edge, renters who cannot modify a building, and local agencies with elaborate hazard plans and suspiciously short equipment lists. That list is analysis, not a finding from Bain—but it follows from the report’s central observation that uninsured losses leave a large remainder for somebody to absorb. The report’s resilience and loss-gap claims are available here.

The most useful detail in Bain’s release is also the least cinematic: some chances to build resilience appear only when an asset is being replaced or refurbished. Bain says steel and cement refurbishment opportunities may come only every 25–35 years, while solar assets offer more frequent opportunities and can incorporate resilience from the start. This is infrastructure’s version of an inconvenient dental appointment. Skip it, and the next available slot is several decades away. See Bain’s asset-resilience findings.

That should change what counts as climate action in a hot, fire-prone future. The big announcement is usually the new project. The decisive moment is often the specification: whether a rebuilding project accounts for heat, whether backup systems are designed for real conditions, whether public facilities can remain usable during prolonged outages, whether a new energy installation is built to keep operating when the surrounding landscape becomes less forgiving. None of those choices is glamorous enough to trend. They are, regrettably, what preparedness looks like before the sirens make it fashionable.

Bain says it analyzed nearly 150,000 assets across 12 sectors and concluded that resilience can be added at particular points for relatively low incremental cost. That is Bain’s analysis, and the release does not supply the full methodology or a universal price tag. Still, the governing principle is sturdier than any consultant’s branding: use the replacement cycle. A country that waits for climate resilience to become a discrete emergency program will keep discovering it during emergencies, at emergency prices. The practical work is to identify the ordinary capital decisions happening now—and stop treating their consequences as somebody else’s weather.
