Earth Hour 2007 March 31, 2007

Global warming is now the greatest threat Australia has ever faced.

At 7.30pm on 31 March this year, we want you to turn off your lights for just one hour - Earth Hour - to show the world that Sydney cares enough about global warming to take action.

Think you can't make a difference?

Turning off lights when you're not in the room and turning your appliances off standby will save up to 10% of our electricity consumption. It's that easy.

Join Earth Hour, switch off your lights on 31 March and help stop global warming. Before it's too late.
