The Climate Change Authority has prepared a series of fact sheets to provide information on a range of climate change issues
Greenhouse gases enhance the natural greenhouse effect by trapping more heat in the Earth’s atmosphere than would be the case without human activity, leading to changes in our climate.
Australia is the world’s 14th largest emitter producing 1 per cent of global emissions.
188 Parties have ratified the Paris Agreement. Ratifying parties have made commitments to take practical steps to reduce greenhouse gas emissions.
Electricity generation is Australia’s largest source of emissions, but electricity emissions have been decreasing since 2009.
Emissions from Australia’s industrial sector arise mainly from manufacturing and mining (including oil and gas).
Transport makes up 19 per cent of Australia’s greenhouse gas emissions and has been steadily increasing.
Agriculture is responsible for 13 per cent of Australia’s emissions in 2019.
Forestry and land use have stored more emissions than they released since 2015.
Waste emissions come from organic matter decaying in landfills and processing and treatment of wastewater.
