Decarbonisation trends for Australian grid electricity, fuels, heavy vehicles, and other emission factors used in corporate GHG inventories.
Company vehicle · kWh
Australia is committed to reducing GHG emissions to 43% below 2005 levels by 2030. A key contribution to this target is the expanded Capacity Investment Scheme to deliver on the government’s target to achieve 82% renewable electricity by 2030.

In Australia, the emission factor for natural gas has not changed in recent years, however recent pilot studies alongside the Energy Networks Australia 20% RGT (renewable gas target) means our projection is for a very modest reduction by 2030.

Australia’s utilities_electricity_grid residual factor could follow a sharper decarbonization path than the CER baseline suggests. Ember’s 2025 forecast envisions the residual market-based factor falling from 0.92 in 2025 to 0.75 by 2030 (Ember, 2025 Forecast), a roughly 19% reduction. This contrasts with CER’s projection of a gradual rise to about 0.98 by 2030 (CER, 2025 Forecast). The drivers underpinning a lower residual factor include: accelerated deployment of wind/solar and storage with ongoing coal retirements (AEMO, 2024); strengthened Safeguard Mechanism reforms tightening baselines for large emitters to accelerate abatement (DCCEEW, 2023–2025); rapid growth of corporate PPAs—around 60% of capacity contracted by 2025—locking in low-emission supply (Briggs, BRCA, 2025); and wholesale-market reforms and transmission investments that embed renewables into the market (AEMO, 2024). Together, these factors support a stronger decarbonization trajectory across au-nsw, au-vic, au-ql, au-sa, au-wa, au-tas, au-nt, and au-act.
