Be Part of Earth Hour

Earth Hour Sat 25th March 8.30 – 9.30pm

It's never been more important to #MakeClimateMatter. Switch off your lights for one hour 8.30pm – 9.30pm.

Last year, more than 10.4 million people in Britain joined in with the Palace of Westminster, Buckingham Palace, The Shard, The Ritz hotel , Old Trafford and Edinburgh Castle among the landmarks which dimmed their lights.

Across the world more than 350 landmarks from New York to Beijing disappeared from view between 8:30pm and 9:30pm local time, including the Eiffel Tower, the Empire State Building and Tokyo Tower.

Earth Hour 2017 takes place at 8:30pm GMT on Saturday March 25. This year teams around the world will be using the movement to shine a light on the climate issue most relevant in their country or region.
