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.
