From its inception as a single-city initiative — Sydney, Australia – in 2007, Earth Hour has grown into a global symbol of hope and movement for change. Earth Hour 2010 created history as the world’s largest ever voluntary action with people, businesses and governments in 128 countries across every continent coming together to celebrate an unambiguous commitment to the one thing that unites us all — the planet.
