Take action for Earth Hour

On March 19th 2016 at 8.30pm, millions of people all around the world turned off the lights for one hour, to celebrate their commitment to the planet. Earth Hour comes back on March 25th 2017. Join the movement and add your name!

Earth Hour City Challenge

"Through the Earth Hour City Challenge, WWF wants to help cities act as global solutions hotspots to speed up our transition towards a renewable energy based and sustainable future and promote the real changes that are being created every day from solar streetlamps to clean transit systems of the world's cities" Yolanda Kakabadse, President of WWF International
