26 March: Earth Hour

On Sunday 26 March we can all take part in an hour that can change decades.

Every year, at 8:30 pm on the last Saturday of March, millions of people across the world join in raising awareness of the issues facing our planet.
But Earth Hour is more than just an Hour for the planet - it's a movement for our future. And it's more than just a symbol of support - it's a catalyst for urgent change.

Join the millions of people, in more than 180 countries, across the world in switching off your lights to show support for our planet:
