Earth Hour 2017

Join us and switch off your lights in a symbolic show of support for our planet

WWF works for a world where people are living in harmony with nature. As well as working to protect iconic species like the tiger, rhino, and panda, WWF is also concerned with respecting and valuing the natural world and finding ways to share the Earth's finite resources fairly. One way WWF invites everyone to get involved is through Earth Hour, which is supported across England, Scotland, and Wales by players of People's Postcode Lottery.

The world is changing – fast. It's been the hottest year on record for the third year in a row and nearly one in six species are now at risk of extinction from climate change. We have the strong foundations for action – from the Paris Agreement to the UK's Climate Act - but now is the time to deliver the action needed to protect our brilliant planet. It's never been more important to show that you care.

Earth Hour is a global movement, which brings millions together across the world to call for greater action. Last year a record 178 countries took part – a number that rises every year. From the Sydney Opera House and the Eiffel Tower to Buckingham Palace and Edinburgh Castle, cities, towns, and communities across the world switch out their lights and come together for an hour, to join a global show of support for action on climate change.

Join us at 8.30pm on Saturday 25th March. To make your Earth Hour matter,

  • Sign up and send a clear message that you want action on climate change right now.
  • Switch off your lights in a symbolic show of global support to protect our amazing planet.
  • Bring your friends, family, or community together and organise a special Earth Hour event.
  • Share your plans on our Earth Hour map.
  • Take a look at the range of fantastic Earth Hour events, and get involved to make this the biggest and best Earth Hour yet!
