Countries around the world are committing to reduce their carbon emissions in an effort to work toward a new global agreement to tackle climate change. Now is the time to raise our voices and demand strong action from world leaders.
What starts as a simple flick of the light switch for Earth Hour brings us all together in a collective display of our commitment to creating a better future for the planet. We need your help to ensure our commitment is stronger than ever and seen all around the world.
Pledge to turn out your lights for one hour on Saturday, March 28 at 8:30 pm local time and take a stand against climate change.
