The High Court ruled on Wednesday that planning authorities in New South Wales must consider overseas emissions when approving new coal mine expansions. This decision has raised fears among Queensland’s mining sector, which is the country's largest coal producer. Industry leaders are concerned that the ruling could spook investors and affect project approvals despite government assurances that existing laws are robust and will be strengthened if necessary.

Story summary
On Wednesday, Australia’s High Court ruled in favor of a Hunter Valley residents' group, halting MACH Energy’s proposed expansion of its Mount Pleasant coal mine near Muswellbrook, New South Wales. The decision was a 3-2 split ruling where three judges agreed that the state's planning commission failed to consider mitigating emissions generated when the coal is sold and burnt overseas. This landmark case means NSW planning authorities must now take into account scope 3 emissions, or downstream greenhouse gas emissions from burning exported coal, when approving fossil fuel projects.
The expansion would have doubled the mine’s output to 21 million tonnes per annum until 2048, with 98% of projected emissions classified as scope 3 emissions. Wendy Wales, a retired science teacher and president of the local community group Denman Aberdeen Muswellbrook Scone Healthy Environment Group (DAMSHEG), celebrated this "groundbreaking decision" that will influence similar cases nationally.
Environmental advocates assert the ruling sets a binding national precedent for fossil fuel projects in NSW, while industry bodies express concern about potential impacts on future investment in resource-rich states like Western Australia.
