What is Earth Hour?
Saturday 24 March – lights out at 8:30pm
WWF’s Earth Hour is the biggest movement to protect our planet.
Hundreds of millions of people around the planet take part in WWF’s Earth Hour every year. Last year around 9 million took part in the UK alone.
People do a wide range of things around the hour to show they care about our planet’s future. Millions choose to mark Earth Hour by going ‘lights out’ for 60 minutes at 8.30pm – a symbolic show of solidarity for the planet.
This year, we want to get as many people in the UK to make a promise for the planet as we can.
