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 2017–18 — 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

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

In 2017–18, Big Lake Gas came in under its baseline — reporting emissions of 112 kt against an obligation of 140 kt, a surplus of 29 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.
