The ClimateTech and GreenTech ecosystem has experienced a remarkable rollercoaster ride in recent years – from the investment boom of 2021 and 2022 to the downturn in 2023.
In 2024, the global number of ClimateTech deals dropped again by 23%. At the same time, total funding volume (including non-dilutive capital such as venture debt) increased compared to 2023. The data suggests that while fewer companies are securing funding, those that do are raising significantly larger rounds.
In this article, we provide a concise overview of the current state of ClimateTech startup funding and present a curated list of over 30 active venture capital firms expected to invest in the space in 2025.
The data presented is based on the State of Climate Tech Report 2024 by Net Zero Insights, a ClimateTech market intelligence provider. The full report is available here: The State of Climate Tech 2024.
It is important to note that the report only includes publicly disclosed funding rounds. Some regions tend to be less transparent in reporting investment activity and deal volumes. As a result, China’s actual share of ClimateTech investment is likely higher than reported.
In addition to relying on leading market studies, Capvisory also collects its own proprietary data through the Capvisory Venture Capital Fund Tracker, which is updated monthly. A detailed analysis based on this data can be found further below.
2024: Europe surpasses the U.S. in ClimateTech funding for the first time
With a total funding volume of $38.88 billion (dilutive and non-dilutive), Europe saw a 45.1% year-over-year increase—significantly outpacing the U.S., which recorded $33.5 billion (+3.1% YoY). This lead is largely driven by substantial debt rounds, including $5 billion for Swedish battery manufacturer Northvolt, $4.75 billion for French battery maker ACC, and €1.1 billion for German heat pump and solar provider Enpal.
Despite the strong growth in total funding volume, the number of deals dropped sharply in both regions: down 24.1% in Europe and 20.8% in the U.S., pointing to a broader decline in deal activity. The number of active investors also fell—by 12.5% in Europe and 14.7% in the U.S.—indicating an increasingly selective and cautious investment environment.
Since 2020, the share of energy-related investments within the broader ClimateTech category has been steadily increasing. In 2024, the majority of capital flowed into battery technologies, solar energy, and hydrogen—clearly the current favorites among investors.
Close behind is green mobility, particularly investments in electric vehicles (EVs) and charging infrastructure. In Europe, for example, Bolt secured a €220 million debt financing round.
29 new ClimateTech funds launched in the past six months
On the equity side, our Capvisory Fund Tracker identified 29 newly launched ClimateTech funds (Venture Capital and Private Equity) over the past six months, raising a total of $37.08 billion. This signals continued optimism from Limited Partners (LPs) and a strong willingness to allocate capital to the ClimateTech space. Most of this capital is expected to be deployed into private companies over the next 12 to 36 months.
Of these 29 funds:
- 22 were venture capital funds, raising a combined $3.64 billion
- 7 were private equity funds, raising $33.43 billion
In total, the Capvisory Fund Tracker recorded 245 new funds during this period, meaning 11.84% of all newly closed funds had a dedicated ClimateTech focus — or roughly one in ten.
Important note: Our tracker focuses on funds that have officially closed capital (not just announced) and covers the USA, Canada, Japan, and the MENA region.
