The 2025 Clean Edge 100, our annual ranking of the top 100 publicly traded companies in clean energy, transportation, water, and the grid, finds continued global industry leadership in the U.S, China, and Europe. Eligible companies are members of Clean Edge’s global equity research universe of more than 650 companies and must receive at least 50% of their revenue from clean-tech activities (pure plays). Companies are ranked according to an equally weighted composite of market capitalization, revenue, and operating profit, with revenue and operating profit both adjusted for clean-tech business exposure.

This year’s list of 100 top-ranked companies includes energy storage & conversion behemoths BYD, CATL, and Tesla; grid infrastructure leaders Eaton, E.ON, and Schneider Electric; and water innovators Ecolab, Veolia, and Xylem. In our inaugural list in 2024 the U.S. and China were tied in geographic representation with 26 listings each, but in this year’s ranking China drops to second place with 23 listings while the U.S. holds the top spot with 26. They are followed by Brazil with seven and the United Kingdom and South Korea tied with five each. Notable companies entering this year’s Clean Edge 100 include technology providers Badger Meter Inc.
