Roma Hub is a oil & gas facility operated by Santos Limited in QLD. Like all covered facilities, LNG processing, gas extraction and pipeline operations release methane and combustion emissions. Under Australia's Safeguard Mechanism, Roma Hub must keep its annual emissions below a stepping-down baseline — or purchase carbon credits to cover any overage.
In 2023–24, Roma Hub came in under its baseline — reporting emissions of 129 kt against an obligation of 151 kt, a surplus of 22 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. Roma Hub generated 21,545 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 Roma Hub with other oil & gas facilities covered by the Safeguard Mechanism.
