Earth Hour 2018
Starting as a symbolic lights out event in Sydney in 2007, WWF’s Earth Hour has grown to become the world's largest grassroots movement for the environment, inspiring individuals, communities, businesses and organizations in more than 180 countries and territories to take tangible climate action for over a decade.
Today, as accelerating climate change and staggering biodiversity loss threaten the planet, we want to leverage the momentum and energy of the Earth Hour movement to connect people to Earth.
Earth Hour 2018 is on Saturday 24 March from 8:30 p.m. to 9:30 p.m. in your local timezone. Different countries are organizing events according to environmental issues that they feel are most relevant to them. Visit www.earthhour.org to see what’s happening in locations around the world.
