Mobil Altona Refinery is a other facility operated by MOBIL OIL AUSTRALIA PTY LTD in VIC. Like all covered facilities, industrial operations generate significant emissions. Under Australia's Safeguard Mechanism, Mobil Altona Refinery must keep its annual emissions below a stepping-down baseline — or purchase carbon credits to cover any overage.
This facility is operating under a multi-year monitoring period (MYMP) — a Clean Energy Regulator-approved arrangement that allows compliance to be assessed across multiple years rather than annually. This is appropriate for facilities where emissions vary significantly year to year due to production cycles or operational changes. The gap shown above does not indicate non-compliance during the MYMP window.
Across the other sector, 8 of 8 covered facilities reported emissions above their baseline in 2023–24. The table below compares Mobil Altona Refinery with other other facilities covered by the Safeguard Mechanism.
