Earth Hour - Saturday March 28, 8.30pm - 9.30pm

Earth Hour is a worldwide campaign that aims to educate the community about the threats of climate change, informing individuals and businesses about the difference they can make by reducing their emissions at home and in the workplace.

Earth Hour and climate change
• Climate change is the most significant threat to life on Earth.
• Greenhouse gas emissions are contributing to the world’s warming. Australia emits around
• 560 million tonnes of greenhouse gases a year – 20 per cent of this comes from households.
• As the Australian climate warms, average annual heat related deaths in older Australians may increase, mosquito-borne disease may spread, agricultural production will be affected by changing rainfall patterns and sea levels will rise.
• Collectively, simple activities like leaving lights on when you leave a room or leaving appliances on standby are direct, unnecessary contributors to climate change.

Earth Hour’s origins and achievements
• Earth Hour is an Australian initiative that began in Sydney in 2007. Approximately 2.2 million people and 2,100 businesses took part in the first year.
• In 2008 Earth Hour was held on Saturday 29 March, 2008 and involved between 50 and 100 million people in 370 cities and towns around the world, including Chicago, Toronto,
• Copenhagen, Dublin, Atlanta and Bangkok took part.
• An independent survey found that in 2008 58 per cent of people in Australian capital cities joined in by switching off their lights.
