Hundreds of millions of people, businesses and governments around the world unite each year to support the largest environmental event in history – Earth Hour - by switching off the lights for one hour.

In 2016, Earth Hour rolled across the world and millions of people came together to shine a light on the climate action our planet needs. The tenth edition of the movement’s signature lights out event saw individuals, communities, organizations and landmarks in an unprecedented 178 countries and territories switch off in solidarity with global efforts to change climate change.
