Earth Hour 2021
Climate action to save earth
A healthy planet is not an option, it is a necessity. About 72% of GHG emissions come from households. Switch to clean energy sources, drive and fly less, recycle and reuse and where not possible, buy less.
History of the Hour
Started by WWF and partners as a symbolic lights-out event in Sydney in 2007, Earth Hour is now one of the world’s largest grassroots movements for the environment. Held every year on the last Saturday of March, Earth Hour engages millions of people in more than 180 countries and territories, switching off their lights to show support for our planet.
But Earth Hour goes far beyond the symbolic action of switching off – it has become a catalyst for positive environmental impact, driving major legislative changes by harnessing the power of the people and collective action.
Earth Hour is open-source and welcomes everyone, anyone, to take part and help amplify the mission to unite people to protect the planet.
