Earth Hour started in 2007 as a lights-off event to raise awareness about climate change. We have grown to engage more than 162 countries and territories worldwide. Earth Hour is on Saturday, 28 March 2015 at 8:30 pm local time.
Earth Hour 2014 was the biggest yet, thanks to you. From driving legislation change to launching our first crowdfunding platform and celebrations for the planet across the world. Share the video now to help spread the word!
