Europe Now Leads Global VC Funding for Climate Tech Startups
Why the Biggest Climate Tech Bets Are Now Being Placed in Europe
The money is still flowing into climate tech, but it is flowing differently now and it is flowing to Europe.
In the first quarter of 2026, European venture capitalists invested $6.6 billion in climate tech, according to PitchBook’s Q1 2026 Climate Tech VC Trends report. That figure is 20% higher than North America’s total for the same period a region that typically leads globally and more than triple what Asia posted. The fact that Europe leads VC funding for climate tech this decisively is a shift worth paying close attention to.
Climate tech VC overall reached $14.3 billion in Q1 2026, the strongest quarterly performance since Q3 2023, continuing a recovery that began in mid-2025. Deal count also broke from a multi-quarter decline, rising 10% quarter-on-quarter to 538 transactions.
Europe claimed the three largest climate tech VC deals of the quarter and the only ones to surpass $1 billion. UK-based Low Carbon Materials, which develops carbon-negative additives that decarbonize concrete and asphalt, raised $1.5 billion in March. German renewable energy startup Cloover closed a $1.2 billion Series A in January, while Octopus Energy spin-off Kraken Technologies secured $1 billion that same month.
But the headline numbers carry a warning. The number of climate tech deals fell to a half-decade low in 2025, dropping from 2,906 transactions in 2024 to just 2,130. Overall deal value held roughly flat at $42.2 billion, meaning capital is concentrating into fewer, larger bets rather than spreading broadly.
That pattern reflects a market recalibrating under pressure. Investors are increasingly funnelling money into AI-enabled climate startups, favouring software and AI tools designed to lower operating costs across energy infrastructure from wind and solar to nuclear and geothermal.
Dispatchable energy sources, covering nuclear and geothermal, extended a strong run, marking the fifth consecutive quarter among the largest on record for the segment. As Europe leads VC funding for climate tech into record territory, the real question is whether the concentration of capital into a handful of giants leaves too much of the sector’s future resting on too few shoulders.
