Toronto, Canada (October 20, 2025) — The inaugural State of CleanAI report finds that investors have poured over US$50billion into ventures using artificial intelligence to tackle climate change and related challenges since 2020. The report shows cleanAI accounts for 10 percent of all venture capital invested in artificial intelligence innovation, a strong indicator of the value creation potential and positive climate impact of the emerging cleanAI category.
Geographic and Sector Dynamics
CleanAI investment remains concentrated. The United States attracted about US$30.2 billion across 845 deals between 2020 and 2025, nearly 60 percent of total VC dollars. Sweden and China each closed a handful of mega‑deals, while Germany and Canada had many smaller financings. Recent mega‑raises such as Commonwealth Fusion Systems’ multi‑billion Series B financings emphasize that investors are betting big on clean energy breakthroughs enabled by AI while also seeing its potential in other sectors such as agriculture, mobility and new materials.
Leading Investors Writing Big Cheques in CleanAI
Leading investors span North America, Europe and Asia–Pacific, including venture funds, corporations and public‑sector institutions. While capital remains concentrated in a handful of regions, the State of CleanAI report finds that investors are increasingly diversifying across cleanAI subsectors. The report highlights the largest investors in each continent, the deals being done across subsectors, and the most exciting companies to watch. Detailed league tables and company profiles are reserved for CleanAI Initiative members.
Nicholas Parker, Founder of the CleanAI Initiative, comments on the findings: “The data make it clear that we’re entering a scaling phase. Momentum is accelerating because investors see how artificial intelligence can drive down costs, boost productivity, and cut emissions while accessing multi-decade, multi-trillion dollar market opportunities. Convergence of AI innovation with sustainability imperatives represents the next wave of industrial competitiveness.”
