Australian High Court Rules Authorities Must Consider Climate Impacts of Coal Exports

The High Court of Australia ruled that authorities are legally required to consider the local climate impacts of a coal mine's downstream pollution before granting approval. The ruling upheld a decision that the Independent Planning Commission failed a mandatory legal obligation when approving the expansion of MACH Energy’s Mount Pleasant coal mine without considering how pollution would affect the region through increased bushfire risk, drought, flooding, and extreme heat. This decision was issued one day after Prime Minister Albanese addressed leaders at Pre-COP31 meetings in Fiji, as countries set priorities ahead of COP31 in Antalya, Turkiye.

The judgment establishes a legal requirement for authorities to assess climate risks associated with coal mine pollution before granting permits. This mandates a change in how resource extraction projects are evaluated, potentially affecting the operational costs and approval timelines for coal mining ventures.
