The Safeguard Mechanism requires Australia's largest industrial facilities to keep net emissions under a legislated, stepping-down baseline — or offset the difference with carbon credits.

Not covered since 2016–17 — this facility's reported emissions have not reached the Safeguard Mechanism's 100,000t threshold since then. Figures below are its last reported year.

What this means

OneSteel Whyalla Steelworks is a facility operated by ONESTEEL MANUFACTURING PTY LIMITED in SA. Like all covered facilities, industrial operations generate significant emissions. Under Australia's Safeguard Mechanism, OneSteel Whyalla Steelworks must keep its annual emissions below a stepping-down baseline — or purchase carbon credits to cover any overage.

In 2016–17, OneSteel Whyalla Steelworks came in under its baseline — reporting emissions of 2.40 Mt against an obligation of 2.54 Mt, a surplus of 136 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.
