Wheatstone Operations is a oil & gas facility operated by CHEVRON AUSTRALIA PTY LTD in WA. Like all covered facilities, LNG processing, gas extraction and pipeline operations release methane and combustion emissions. Under Australia's Safeguard Mechanism, Wheatstone Operations must keep its annual emissions below a stepping-down baseline — or purchase carbon credits to cover any overage.
In 2023–24, Wheatstone Operations came in under its baseline — reporting emissions of 4.07 Mt against an obligation of 4.30 Mt, a surplus of 234 kt. Facilities that come in under baseline can generate Safeguard Mechanism Credits (SMCs), which can be sold to facilities that need to cover an overage. Wheatstone Operations generated 233,751 SMCs in 2023–24.
Across the oil & gas sector, 8 of 8 covered facilities reported emissions above their baseline in 2023–24. The table below compares Wheatstone Operations with other oil & gas facilities covered by the Safeguard Mechanism.
