Join the movement
Earth Hour is a global movement uniting people to protect the planet. By asking individuals, cities, landmarks and business to turn their non-essential lights off for one hour and commit to reducing their environmental impact, we are showing everyone that the world's environmental issues don't have to overwhelm us. Small things we do every day can make a better future. Join the movement and make your commitment to a better planet.
