Welcome to the Earth Hour global community!

According to the International Energy Agency, the power sector is responsible for 37% of the CO2 equivalent emissions worldwide. For appliances, electronics, and lighting - making up around one third of this sector - the energy efficiency savings potential is roughly 50 per cent. WWF supports Topten, an international network promoting clean technologies and energy efficient appliances, and cars . Currently, seventeen European countries, China and the USA are part of Topten. And through Topten's national websites, around two billion consumers currently have access to information on ways to improve their energy efficiency. 

The objective is to combat climate change through energy efficiency. The Topten quick and easy information on the most energy efficient products greatly improves access to these products so that people can buy, sell and manufacture more energy efficient products. And save money too! You’re only one click away from taking climate action. For more information check out www.topten.info
