Every year, at 8:30 pm on the last Saturday of March, supporters in over 190 countries and territories unite, taking action on and raising awareness of the issues facing our one home. 

But Earth Hour is more than just an hour for Earth – it’s a movement for our own futures, for the benefit of people and  planet.

And it’s not only a symbol of solidarity – it’s a catalyst for change, harnessing the power of the crowd.
