Our annual list of the top 100 publicly traded pure play companies in clean energy, transportation, water, and the grid
The Clean Edge 100 ranks the top publicly traded clean-tech companies in the clean energy, transportation, water, and grid sectors. Eligible companies are members of our global equity research universe and the rankings only include companies that are determined to receive 50% or more 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. Revenue and operating profit are adjusted by business exposure as evaluated by Clean Edge.
The list of 100 top-ranked companies includes energy storage & conversion behemoths BYD, CATL, and Tesla; grid infrastructure leaders Schneider Electric, Eaton, and National Grid; and water innovators Ecolab, Xylem, and American Water Works. U.S.-domiciled and China-domiciled companies lead the pack with 26 listings each, followed by Brazil with seven and France and South Korea tied with five each. In terms of the top sectors in this year’s rankings, renewable energy leads with 28 companies, followed by grid, water, and energy storage & conversion with 27, 19, and 17 selections respectively.
