Our actions today, as individuals and global community, will determine what the world will look like for generations to come. What is Earth Hour? The world is at the crossroad of climate change, and our actions still aren't enough to reduce it. Earth Hour is one of the many initiatives aimed at addressing environmental issues. During the Earth Hour, cities around the world come together to put off all its non-essential lights for an hour (08:30 pm - 09:30 pm), at the end of March, as a symbol of their commitment to the planet. It is a voluntary power cut by people around the world in a fight against climate change. This year's theme is a celebration of "Places We Love," such as beaches, forests, reefs, snow-capped mountains and rivers which could be at risk from climate change. Sydney was the first this year to switch off its light to observe Earth Hour, while others followed.

Time for lights out! We're proud to take part in this year's #EarthHour

How do you celebrate Earth Hour?

To join the cause you must switch off all non-essential lights during the one hour that the Earth Hour is observed. This is how you make your contribution in fighting climate change.
