WWF’s Earth Hour 2015 countdown began with the release of a video demonstrating how Earth Hour is empowering individuals and organisations around the world to take action. Showcasing memorable moments and achievements from past Earth Hours, plus statements from world leaders and personalities, the video aims to inspire people with the message to act and ‘use your power to change climate change’. Since 2007, Earth Hour has grown from a symbolic lights-off event in Sydney, Australia to the world’s largest open-sourced environmental campaign, mobilizing hundreds of millions of people in more than 7,000 cities and 163 countries.
