Earth Hour 2017

8:30 p.m. your local time on Saturday, March 25

Every year, hundreds of millions of people around the world switch off their lights for one designated hour to demonstrate a commitment to fighting climate change.

This year, Earth Hour takes place at 8:30 p.m. local time on March 25. There’s never been a more critical moment for the world to show solidarity for and a strong commitment to climate action. By going dark, local government, cities, companies, landmarks, and individuals send the message that we will remain steadfast as we deliver on the goals of the Paris Climate Agreement.

Momentum is on our side. The world is looking toward a renewable future. This Earth Hour, turn up the dark and get loud about climate action. Let the world know you’re all in. 

Are You In? Let Us Know!h
