Join the global celebration

Join us for the world’s biggest celebration for our amazing planet! Simply add your name and switch off your lights for an hour on Saturday 19th March 2016 between 8.30pm and 9.30pm to show you care about the future of our planet.

The lights out really is just the beginning. At its heart, WWF’s Earth Hour is a community of people who are sharing their love for our planet and taking action to protect it every day.


In the UK alone, we’re consuming three times our fair share of the planet’s natural resources, and we’re facing the biggest environmental challenge our generation has ever seen – climate change. It’s real, it’s happening now and it’s affecting the things we all love, but the good news is that we can make a difference.
