What this means
Western Australia is a aviation facility operated by Alliance Aviation Services Limited in WA. Like all covered facilities, jet fuel combustion generates significant Scope 1 emissions across the national fleet. Under Australia's Safeguard Mechanism, Western Australia 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 aviation sector, 2 of 3 covered facilities reported emissions above their baseline in 2023–24. The table below compares Western Australia with other aviation facilities covered by the Safeguard Mechanism.
