New data shows Australia's climate pollution is down 1.6% as solar, wind and batteries continue to replace more expensive coal and gas generation in Australia's electricity grids.
The latest Quarterly Update of Australia's National Greenhouse Gas Inventory estimates 455.6 million tonnes of emissions over the year to March 2026 - a 7.5 million tonne drop over the previous year.
Record high generation from renewables drove a 5.6 million tonne cut in electricity emissions as it continued to displace coal and gas-fired generation. That represents a 3.7% decline.
This comes as the Clean Energy Regulator confirms the June quarter has set new records, with over 1 GW of rooftop solar installed and 1.8 GW of large-scale solar final investment decisions.
Fugitive and stationary energy emissions also fell by a combined 1.7 million tonnes, due to reductions in natural gas venting, underground coal mining and oil and gas extraction.
Electricity emissions are falling steadily as Australians add more batteries and renewables at a household, community and grid level, driven by policies like the Cheaper Home and Community Batteries programs.
The trend is expected to continue as the Capacity Investment Scheme supports an additional 26 GW of solar and wind generation across the country, backed by 14 GW of new clean energy storage.
Minister for Climate Change and Energy Chris Bowen said the results showed the practical benefits of building Australia's cleaner, cheaper and more reliable energy system.
"The latest quarterly update is further proof that what's better for the planet is better for your pocket; more of the cheapest form of new energy, more storage to back it up, and lower emissions as a result," Minister Bowen said.
"With over 4 million household solar systems and more than half a million home batteries supported by our Cheaper Home Batteries Program, we're seeing the results of consistent and considerable cuts in electricity grid emissions.
"Meanwhile the Coalition and One Nation are promising higher bills and higher pollution - that's not the real change Australia needs."
More domestic air travel and diesel road transport drove the 0.2% increase in overall transport emissions, which was tempered by falling petrol use as more Australians move to electric vehicles.
The small increase in transport emissions follows drops in the years to September and December 2025, with levels still below the record high in the year to December 2024 - the last period before the New Vehicle Efficiency Standard came into effect.
"Australia is turning the corner when it comes to stubborn transport pollution - that's good news for motorists as more drivers embrace cheaper to run cars thanks to our policies delivering more choice to the market."
