MIT Is Naming 10 Climate Tech Companies That Could Actually Save Us

The news is not good. Earlier this month, the United Nations said the planet will likely pass 1.5 °C of warming — the ambitious target of the Paris climate agreement — within the next few years. In the US, the world's second-biggest polluter, the current leadership keeps denying climate science and rolling back climate policies. Big Tech, meanwhile, is quietly backing away from its own climate promises as it races to build giant data centers to power AI. Add another summer of record heat, wildfires, and floods, and it's easy to feel hopeless.

But MIT Technology Review argues there's a real counter-story. Every year, its editors and writers dig through industry knowledge and academic sources to build a long list of companies worldwide that are changing how we make energy, produce goods, move people, and protect cities from extreme weather. After several rounds of newsroom debate, they cut that list down to 10 — the companies they think have done the most, or have the best shot, at meaningfully cutting emissions or improving public health and safety.

That 2026 list is now finished and will be published on October 6. It includes a mix of companies working on energy storage, nuclear power, and transportation — including some that have found ways to keep growing even in today's politically hostile climate.

The bigger point is about mindset. Cost declines and public demand keep pushing clean technology forward, even when governments stall. Solar, batteries, and electric vehicles are getting cheaper and better without much fanfare. The list is a reminder that progress doesn't need permission from politicians — and that paying attention to who's building it is worth your time.
