How you can make climate matter

An annual event, Earth Hour is the world’s largest demonstration of support for action on climate change. Earlier this year, millions around the world across 178 countries came together to show support for action to protect our amazing planet. Now, more than ever, it’s crucial we show support for action on climate change. You can still be part of it. Sign up to show you support action on climate and we’ll use your support to show political and business leaders we all want action on climate change. We’ll keep you posted with our latest campaigns and actions you can take to support climate action.

Don’t forget to save the date for next year’s Earth Hour, which will fall on Saturday 24th March 2018.
