80 UK Climate Tech Startups To Know

From Energy to Food production - a list of the the top UK Climate startups

We’ve previously mapped Switzerland and France’s Climate Tech startups and up next we jump across the Channel and into the UK.

Despite being a (relatively) tiny island, the UK is making major strides in climate tech, doubling its investment year-on-year to nearly $8 billion in 2022.

We took to LinkedIn again to track down the British climate tech founders you really need to know.

If there’s someone you think we’ve missed, please add them to the list here.

Before jumping in… if you’re interested in UK’s Climate Tech scene, you’ll want to join us at this years HackSummit on May 11th and 12th.

With attendance from some of the top Climate founders and VC’s including Lowercarbon Capital, Planet A Ventures, Ecovative, Zero Carbon Capital, and many more.
