What is Earth Hour?

Earth Hour is the world’s biggest switch off event – it gives a powerful voice to people everywhere who want to put the world on the path to recovery. Each year, millions of people around the world switch off their lights and organise events – at home, in their community or in their towns or cities – to show they care about the future of our planet. 

Last year over 10 million people across the UK took part to send a clear message: we’re fighting for our world. From the Sydney Opera House and the Empire State Building to Buckingham Palace and Edinburgh Castle, communities like yours switched out their lights in a symbolic show of support.  

Your support for Earth Hour has helped us find solutions for the environmental challenges we face the world over. This includes influencing national climate policies, planting new forests in Uganda, and banning plastic in the Galapagos. 

Join us at 8.30pm on Saturday 30 March 2019.
