Earth Hour is a WWF initiative where YOU can show your support for action on climate change by turning off your lights for one hour to show your support and commitment.

Earth Hour is a symbolic event designed to engage people from all walks of life in the climate change discussion to send a strong message to our political leaders that we want them to take meaningful action on climate change. Since it began in Sydney in 2007, Earth Hour has inspired the world, reaching more than one billion people in more than 4,000 cities and towns globally in 2009.
