Notes to the Editors:


Earth Hour Impact

Starting as a symbolic ‘lights out’ event in 2007, Earth Hour has grown to become a true mass

movement exemplifying the power of people in driving seismic changes. The spirit of Earth Hour

was demonstrated recently in Uganda which announced a ban on plastic use following an Earth

Hour lead-up march on 13 February against the ill-effects of plastic pollution. This is not a stand-alone example.


Previously, the movement helped create a 3.5 million hectare marine-protected area in Argentina and a 2,700-hectare Earth Hour forest in Uganda, ban all plastics in the Galapagos in 2014, plant 17 million trees in Kazakhstan, light up homes with solar power in India and the Philippines and push new legislation for the protection of seas and forests in Russia. Just last year, French Polynesia moved to protect 5 million square kilometres of its seas to preserve ocean ecosystems.

About Earth Hour 


Earth Hour is WWF's flagship global environmental movement. Born in Sydney in 2007, Earth Hour has grown to become one of the world's largest grassroots movements for the environment, inspiring individuals, communities, businesses and organizations in more than 180 countries and territories to take tangible environmental action for over a decade. Historically, Earth Hour has focused on the climate crisis, but more recently, Earth Hour has strived to also bring the pressing issue of nature loss to the fore. The aim is to create an unstoppable movement for nature, as it did when the world came together to tackle climate change. The movement recognizes the role of individuals in creating solutions to the planet’s most pressing environmental challenges and harnesses the collective power of its millions of supporters to drive change.
