Australia recorded its biggest emissions drop since Covid, with a 2.2% fall in the year to June.
Preliminary data shows an even larger 2.8% fall in the year to September.
At this pace, Australia is on track to meet its 2030 target of a 43% cut below 2005 levels.
Electricity led the decline, delivering half of the nearly 10 million tonnes of reductions as renewables displaced coal and gas.
Stationary energy emissions also fell due to efficiency gains and lower gas use, while transport emissions rose with higher diesel use.
Grid emissions intensity hit a record low of 0.55 tonnes CO2-e/MWh in the June quarter, with electricity emissions now 30% below their 2009 peak.
Chris Bowen told parliament the 2035 target of a 62–70% cut is still within reach but will require faster action.
The Climate Change Authority warned emissions reductions must triple to hit the 2035 goal.
The CCA said approvals and delivery of clean energy projects must accelerate as coal exits and renewables surge.
Falling costs of solar, batteries, EVs, heat pumps and electrification are expected to drive further cuts across the wider economy.
