SCROLL TO EXPLORE the 2025 listScroll down

Every year, the MIT Technology Review newsroom produces this list of some of the most promising climate tech firms on the planet. It’s an exercise that we hope brings positive attention to companies working to decarbonize major sectors of our economy, whether by spinning up new, cleaner sources of energy or reinventing how we produce foods and distribute goods.
