Under the National Greenhouse and Energy Reporting Act 2007 the Clean Energy Regulator publishes a point-in-time extract of electricity sector emissions and generation data each year.
Electricity generation and scope 1 emissions from 2016–2019
Emissions in the electricity generation sector have decreased over the last three years. There was a notable reduction of 6.8 Mt CO2-e (3.8 per cent) in 2017–18 and 4.8 Mt CO2-e (2.9 per cent) in 2018-19 on the previous reporting year.
In 2019, Australia set a new record for total electricity generated from renewables. For the 2018-19 reporting year renewables became the second largest electricity generation fuel source (17 per cent), while black coal remains the largest (53 per cent). The Clean Energy Regulator expects that the national energy mix will continue to evolve.
