MIT Technology Review to Publish 2026 Climate Tech Companies to Watch on October 6

In an article announcing the list, MIT Technology Review said the release comes as the United Nations earlier in September announced the planet will tip past 1.5 °C of warming “likely within the next few years.” The publication said the United States, the world’s second-largest emitter, has a leader who continues to deny climate realities and unravel climate policies, while Big Tech is backpedaling on climate ambitions as companies race to build massive AI data centers. It also cited another season of shattered heat records, raging wildfires, and deadly floods.

Despite those headwinds, the publication said the world has made progress. Companies are developing and deploying renewables, batteries, and electric vehicles; inventing cleaner ways to produce industrial goods; and devising ways to keep cities and people safe amid more extreme weather, according to MIT Technology Review. It said those advances will accelerate as costs decline and people demand greater climate action, along with the economic and health benefits that come with it.

MIT Technology Review said it began publishing the annual list three years ago. Each year, editors and writers use their industry knowledge and academic sources to compile a long list of companies around the world that are transforming how energy is generated, goods are produced, people and things are moved, or rising climate dangers are mitigated. The publication then conducts several rounds of newsroom debate to narrow the list to 10 companies. The 2026 list is finalized and will be published on October 6.

The same message appeared in the September 29 edition of The Download, MIT Technology Review’s weekday newsletter. It said the 2026 list includes a mix of companies making strides in energy storage, nuclear power, transportation, and other areas, including ones that have found ways to continue progress despite current climate politics. The publication said it hoped readers would come away feeling more hopeful that the world can move fast enough to avoid the gravest dangers of climate change and build a safer, healthier, and more sustainable world.

The Download also reported on a separate dispute over AI and scientific discovery. MIT Technology Review said that last week Anthropic announced its new molecular biology lab had made its first discovery: its AI agents flagged a previously uncatalogued pattern surrounding an enzyme, a pattern “reminiscent” of what led to the gene-editing technology CRISPR. But the claims angered biologists, the newsletter reported. Some questioned whether merely finding the pattern amounted to a discovery at all. Another said his team had already discovered the same pattern, raising questions about whether Anthropic’s system had learned from his conversations with Claude.

MIT Technology Review said the episode is a reminder that what is novel for AI may be routine, unsurprising, or simply not that consequential to a biologist. It added that grand claims could make real progress harder to recognize.
