In a video message, UN Secretary-General António Guterres, said: “Climate change continues to imperil lives and livelihoods around the world. Last year was – again – the hottest on record. The landmark Paris Agreement gives us an unprecedented opportunity to limit global temperature rise, promote clean energy for all and create a sustainable future.” Governments and businesses must step up. So must individuals. Building a sustainable tomorrow depends today on everyone, said the UN chief, asking the world to join him in turning off their lights on today at 8:30 p.m. local time. “From the darkness, we can create a sustainable and inclusive world for all,” he said. Organized by the World Wildlife Fund (WWF), Earth Hour encourages individuals, companies, organizations and Governments to switch off their lights for one hour at 8:30 p.m., local time worldwide, to focus attention on people-driven solutions to protecting the planet and building a bright, sustainable future.First launched in 2007 in Australia, Earth Hour has become an annual event, mobilizing hundreds of millions of individuals to participate and growing to become the world’s largest grassroots movement for the environment.

Hundreds of landmarks – from New York to Uganda and Sweden to Malaysia – are confirmed and will be turning off on the night of Earth Hour, including iconic sites such as the Eiffel Tower, Taipei 101, the Empire State Building and the Acropolis. To inspire more people to act, this year the Earth Hour movement is also inviting supporters to show their commitment to the cause on their Facebook timelines, in parallel to the lights out rolling across skylines. People around the world can log onto earthhour.org/climateaction to donate five Facebook posts to Earth Hour and encourage their friends to be a part of local climate efforts. They can also use a new Facebook profile picture frame available on www.facebook.com/earthhour to celebrate Earth Hour on their own personal landmark – their Facebook page.
