What this means

Koodaideri Mine is a facility operated by Mount Bruce Mining Pty Ltd in WA. Like all covered facilities, industrial operations generate significant emissions.

In 2024–25, Koodaideri Mine came in under its baseline — reporting emissions of 151 kt against an obligation of 594 kt, a surplus of 443 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.
