As energy demand rises around the world, in part due to new data centers and widespread use of AI, greentech and climatetech are gaining investment, according to analysts at JP Morgan. Renewable energy has been increasing in capacity and decreasing in cost, helping meet the modern era’s energy new energy needs, and investors continue to seek solutions for stabilizing the grid and transforming outdated energy infrastructure. To highlight the companies driving the transition to a greener world, TIME partnered with data firm Statista on the second annual ranking of the World’s Top GreenTech Companies, naming the 250 top performing companies that either develop or provide green technologies, products, or services that help mitigate or reverse the environmental impacts of human activity.
Methodology: How TIME and Statista Determined the World’s Top GreenTech Companies of 2026
On the 2026 list, the U.S. was home to the majority of top greentech companies, with 57.2% of headquarters based stateside, headed by geothermal provider Fervo Energy (no. 4) and agriculture innovator Pivot (no. 5). The country with the second largest portion of companies on the list is France, which is one of the leading renewable energy producers and sustainability innovators in the EU with a €240 million plan unveiled in April to further reduce its fossil fuel reliance.
Renewable energy companies—including companies using solar, wind, geothermal, fusion, or biomass to generate power; or creating infrastructure for clean energy production—make up 34% of the list. The top two companies, Canada-based General Fusion (no. 1) and Eavor (no. 2), both fall under this category. General Fusion is a nuclear energy startup specializing in a technique called magnetized target fusion that plans to go public on the U.S. stock exchange through a $1 billion SPAC deal in mid-2026.
Eavor is developing “closed loop” geothermal energy that keeps fluids contained in one system by sending water into deep underground wells to heat then drawing it up through a separate well, instead of just drawing up already heated water or steam. The company piloted its technology in a town in Germany, through which it learned that the technology works and is cost-competitive, and has amassed $365.3 million in funding.
