Carosue Dam Operations

Carosue Dam Operations is a metal ore mining facility operated by NORTHERN STAR (CAROSUE DAM) PTY LTD in WA. Like all covered facilities, iron ore, gold and base metal mining uses significant diesel and electricity. Under Australia's Safeguard Mechanism, Carosue Dam Operations 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 metal ore mining sector, 8 of 8 covered facilities reported emissions above their baseline in 2023–24. The table below compares Carosue Dam Operations with other metal ore mining facilities covered by the Safeguard Mechanism.
