2026 Climate Tech Companies to Watch

The article highlights the critical need for climate technology innovations to address global warming.

It notes that drastic reductions in emissions are required to avoid severe climate impacts, while also adapting to changes already underway.

The MIT Technology Review annually compiles a list of promising climate tech companies, including startups and multinational corporations, working on solutions to either reduce greenhouse gas emissions or help societies adapt to a warming world.

The 2026 list focuses on technologies addressing acute challenges such as energy storage, flood protection, and cleaner industrial processes.

The urgency stems from the Intergovernmental Panel on Climate Change (IPCC) warnings that global temperatures must not exceed 1.5°C above pre-industrial levels to avoid catastrophic effects.
