What is Earth Hour?
Earth Hour is a worldwide event that is organized by the World Wide Fund for Nature (WWF), encouraging households and businesses to turn off their non-essential lights for one hour to raise awareness about the need to take action on climate change.

When and Where did it all start?
The first ever Earth Hour event took place in 2007, in Australia: 2.2 million individuals and more than 2,000 businesses turned off their lights.

In 2008, the City of Toronto, Canada, signed up as well, and it wasn’t long before 35 countries and almost 400 cities and towns were part of the event.

With the invitation to ‘switch off’ extended to everyone, Earth Hour quickly became an annual global event. It’s scheduled on the last Saturday of every March – closely coinciding with the equinox to ensure most cities are in darkness.

In 2011, Earth Hour saw hundreds of millions of people across 135 countries switch their lights off for an hour. But it also marked the start of something new – going Beyond the Hour to commit to lasting action on climate change.
