Earth Hour 2015
Earth Hour returns to raise awareness about climate change - switch your lights off between 8.30pm - 9.30pm to make your mark on the global hour of unity.
Earth Hour, a worldwide lights-off event to raise awareness about climate change, returns for 2015. More than 162 countries and territories worldwide are engaged, so make sure you take part too. It has grown to be more than a one-off event, but a movement that has achieved massive environmental impact, including legislation changes by harnessing the power of the unified crowd.
Light a candle, even sit with friends and follow the event online as it progresses. Remember to use the hashtag #EarthHour on Twitter too and smash the 1.9 billion tweets from last year.
