Macedon

Macedon is a facility operated by WOODSIDE ENERGY GLOBAL PTY LTD in WA. Like all covered facilities, industrial operations generate significant emissions. Under Australia's Safeguard Mechanism, Macedon must keep its annual emissions below a stepping-down baseline — or purchase carbon credits to cover any overage.

In 2024–25, Macedon reported emissions of 113 kt against a baseline obligation of 100 kt — an overage of 13 kt. The facility covered the 13 kt overage by purchasing 13,092 Australian Carbon Credit Units (ACCUs) — credits generated by carbon abatement projects elsewhere in Australia such as soil carbon farming, avoided land clearing, and landfill gas capture.

Purchasing credits is legal and intended by the Safeguard Mechanism's design — the policy deliberately allows facilities to choose between cutting on-site emissions or funding abatement elsewhere in the economy. Whether credit purchases represent genuine long-term decarbonisation depends on whether the facility's absolute emissions are trending down over time. The chart above shows the trajectory since reporting began. This question applies to all covered facilities under the Safeguard Mechanism, not Macedon specifically.

Among 8 comparable facilities, 8 reported emissions above their baseline in 2024–25. The table below compares Macedon with other facilities covered by the Safeguard Mechanism in the same classification.
