25 Climate Tech Startups to Watch in 2024
The effects of climate change continue to break grim records this year. The mercury is climbing. Species are dying. Atmospheric carbon is concentrating. But entrepreneurs keep inventing new technologies to counter these trends.
Trellis’s annual 25 Climate Tech Startups to Watch features startup innovations for everything from plant-waste plastics to less toxic batteries to carbon dioxide removal.
New climate technologies are critically needed — and proving resilient to a recent funding slowdown. Climate startups raised $3.4 billion, or 4.8 percent of all VC fundraising, in the first half of 2024. That’s up from 2 percent in 2023, according to Pitchbook’s 2024 Climate Tech Funds Report.
Federal policies such as the Inflation Reduction Act, plus new U.S. and European Union regulations, offer a fresh push for businesses to adopt low-carbon solutions. Large corporations seek innovations from new ventures.
Why these 25 startups stand out
Every startup on the Climate Tech 25 has seed or series-A funding and demonstrates an edge in each of five criteria: its solution, business model, customer need, customer traction, team and pitch presentation. All are incorporated, have already developed a product and employ at least one person full-time.
Our team of climate experts narrowed 108 submissions down to five of the most promising companies in each of the five categories.
