From Antarctica to the International Space Station, WWF’s Earth Hour transcended borders on Saturday 28th March 2015 mobilizing millions to use their power to take climate action. In a year of record participation, individuals, businesses, city skylines and more than 10,400 landmarks in 172 countries and territories switched off their lights as a symbol of their commitment to change climate change. From the first lights out event in Samoa, across seven continents to Tahiti, the ‘hour’ inspired unprecedented unity and actions from people around the world to tackle local climate issues such as access to sustainable food, renewable energy, climate education and drive climate-friendly policy and legislation.
