Greenhouse gas emissions by Australia
climate changing gases from Australia
Greenhouse gas emissions by Australia totalled 533 million tonnes CO2-equivalent based on greenhouse gas national inventory report data for 2019; representing per capita CO2e emissions of 21 tons, three times the global average. Coal was responsible for 30% of emissions. The national Greenhouse Gas Inventory estimates for the year to March 2021 were 494.2 million tonnes, which is 27.8 million tonnes, or 5.3%, lower than the previous year. It is 20.8% lower than in 2005 (the baseline year for the Paris Agreement). According to the government, the result reflects the decrease in transport emissions due to COVID-19 pandemic restrictions, reduced fugitive emissions, and reductions in emissions from electricity; however, there were increased greenhouse gas emissions from the land and agriculture sectors.
Australia uses principally coal power for electricity, accounting for 66% of grid-connected electricity generation in 2020, but this is rapidly decreasing with a growing share of renewables making up the energy supply mix, and most existing coal-fired power station scheduled to cease operation between 2022 and 2048. Emissions by the country have started to fall and are expected to continue to fall in coming years as more renewable projects come online.
Climate Action Tracker rates Australia's overall commitment to emissions reduction as "insufficient". Policies and action is "insufficient", domestic target is "almost sufficient", fair share target is "insufficient", and climate finance is "critically insufficient". This is because the Australian government has continued to invest in natural gas projects, refused to increase its 2030 domestic emissions target, and is not on track to meet its current target.
“Greenhouse gas emissions by Australia” enters the record as climate changing gases from Australia. Crown Archives preserves that source wording while asking what Greenhouse, emissions and Australia can confirm, complicate or overturn.
Why this record matters
“Greenhouse gas emissions by Australia” is worth following because a concise public description often conceals a longer documentary argument. Here, Greenhouse, emissions and Australia provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Feb 25, 2026. The linked authority identifier is Q5165788. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2019, 2021, 2005 and 2020.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
