Golden Gate Bridge Off for Earth Hour

Earth Hour 2016

Thank you for participating!

Millions of people from a record-breaking 178 countries and territories united for climate action by turning off their lights for Earth Hour. On March 19, the event rolled across the world from Samoa to Santiago, powered by individuals, communities, organizations and landmarks.

For the first time in the fight against climate change, momentum is on our side. In December, leaders from 196 nations heeded the world’s collective call to act together with urgency to address climate change. We have reached a turning point, but we still need your support to secure a low-carbon world. We know that it will take collective action from everyone—governments, businesses, communities and individuals—to turn the tide and stop the worst effects of a warming world.

Now that you’ve turned off your lights to recommit to the fight against climate change, keep the momentum going by telling our leaders to take action at home and support the transition to low-carbon economies worldwide.

We hope you join us again for Earth Hour at 8:30 pm on Saturday, March 25, 2017!

Tell our leaders to take action on climate change.
