Every year, the MIT Technology Review newsroom produces a 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 the economy, whether by spinning up new, cleaner sources of energy or reinventing how we produce foods and distribute goods. Though the political and funding landscape has shifted dramatically in the US since last year, nothing has altered the urgency of the climate dangers the world now faces—we need to rapidly curb greenhouse gas emissions to avoid the most catastrophic impacts of climate change. This project highlights the firms making progress toward that end. Check out the third annual edition of the list, and learn more about why we selected these companies. Our best weapon against climate change is ingenuity —Bill Gates is a technologist, business leader, and philanthropist. It’s a foregone conclusion that the world will not meet the goals for limiting emissions and global warming laid out in the 2015 Paris Agreement. Many people want to blame politicians and corporations for this failure, but there’s an even more fundamental reason: We don’t have all the technological tools we need to do it, and many of the ones we do have are too expensive. But I don’t think this is a reason to be pessimistic. I see it as cause for optimism, because humans are very good at inventing things. In fact, we’ve already created many tools that are reducing emissions. And I am confident that more positive changes are coming. Read the full story.
