Get involved with Earth Hour!

Earth Hour is a beautifully simple idea that’s become a massive global phenomenon - successfully uniting an extraordinary number of people across the planet, year after year, in a small symbolic act with a huge environmental message.

Hundreds of millions take the time to switch off lights for an hour on the last Saturday in March - fired up by the thought of doing something positive to help tackle climate change and protect the natural world from the impacts of our resource-hungry lifestyles.
