2026 Climate Tech Companies to Watch

10 Climate TechCompanies to Watch

    Each year, the MIT Technology Review team puts together a list of some of the most promising climate tech companies in the world. Whether early-stage startup or multinational corporation, the businesses we’ve chosen are working on technologies to help us address climate change or adapt to our warming world.

    There’s an urgent need for these innovators: We must begin to drastically reduce emissions to avoid the deadliest impacts of climate change, while also contending with its harmful effects.

    We hope that this list highlights the progress the world is making to tackle the climate crisis, as well as the breadth of solutions required. From energy storage powered by carbon dioxide to cleaner ways to make cement and refine critical minerals, these companies are building technologies to address the acute challenges we face.

    This is the fourth annual edition of this list. Learn more about how we chose the 2026 slate.
