AI boom dominates climate tech funding at NY Climate Week

At New York Climate Week, much of the climate tech community — like the rest of the U.S. economy — is eagerly riding the AI wave. Some have reservations about the sheer quantity of natural gas power plants being built to power AI data centers, but because many climate tech startups are energy-focused or energy-adjacent, the buildout has been embraced as an opportunity to get companies through the “valley of death.” The singular focus also means some promising sectors risk being overlooked.

It’s a continuation of a trend that has emerged over the last year. As climate tech companies struggled to get financing — either because of canceled federal grants or investor hesitancy — those that could change their pitch to match the AI mania did so. The pivot has helped many climate tech startups land fresh funding: total venture deal value has risen for four consecutive quarters, cresting the $14 billion mark in the first quarter of this year, according to the most recent available data from PitchBook. It’s the best fundraising environment for climate tech in the last few years, with most of the deal value driven by sectors boosted by data center construction, including the built environment, grid infrastructure, and dispatchable energy that can be turned on or off when it’s needed.

Not everyone agrees the trade-off is worth it. Some founders say the data center boom is distracting from other promising segments of climate tech, including those meeting their targets without relying on AI mania. “Corporates are still interested in climate,” one founder told TechCrunch. The difference today, the founder said, is that large companies don’t want to publicize their climate work, largely for fear of drawing the Trump administration’s ire.

There are also signs the AI boom is wearing thin on some in the sector. For many startups, money for scaling was hard to find three years ago even when they were showing promising results; now, customers are seeking out demos on their own. It’s simply the environment founders operate in today, and the ones adapting fastest are finding ways to meet customers where they are. The undercurrent at Climate Week is that the data center party won’t last forever, but it might last long enough to help startups build durable businesses — and once that happens, they can refocus on the carbon-cutting mission they were founded to pursue.

Why it matters

Climate tech’s funding recovery is now downstream of AI infrastructure spending rather than climate policy, which means the sector’s next slowdown is as likely to come from an AI capex pullback as from a change in climate politics.
