Each year, millions of people around the world switch off for Earth Hour to shine a light on climate action. Be a part of the movement towards building a better tomorrow for our planet and future generations. ​Take one hour to power down by shining a light on climate action and change climate change. 

Climate change remains a big challenge for us all. But another urgent threat now demands our attention: the loss of nature. These two combined threats mean we must act - and now.

Starting as a symbolic lights out event in Sydney in 2007, WWF’s Earth Hour has grown to become the world's largest grassroots movement for the environment, inspiring individuals, communities, businesses and organizations in more than 180 countries and territories to take action for our shared home💪🌎 From our forests to our oceans, we have achieved many amazing things for our climate and its biodiversity - showing us that together, anything is possible.

Join the online conversation using #Connect2Earth and #NewmarketEarthHour and show your ❤️ for our 🌎. Let ​us know what you are doing to power down and shine a light on climate action by making Earth Hour 2019 in Newmarket the biggest one yet!
