What this means

Liberty Primary Steel Whyalla Steelworks is a steel manufacturing facility operated by ONESTEEL MANUFACTURING PTY LIMITED in SA. Like all covered facilities, steelmaking from iron ore releases large quantities of CO₂ through the coking coal process. Under Australia's Safeguard Mechanism, Liberty Primary Steel Whyalla Steelworks must keep its annual emissions below a stepping-down baseline — or purchase carbon credits to cover any overage.

In 2023–24, Liberty Primary Steel Whyalla Steelworks reported emissions of 1.19 Mt against a baseline obligation of 1.03 Mt — an overage of 165 kt. The facility has not yet surrendered credits to cover this overage — this may indicate an excess emissions situation or a multi-year arrangement not yet reflected in the published data.

Across the steel manufacturing sector, 3 of 5 covered facilities reported emissions above their baseline in 2023–24. The table below compares Liberty Primary Steel Whyalla Steelworks with other steel manufacturing facilities covered by the Safeguard Mechanism.
