Quick Summary

The High Court has declared invalid an approval for expanding a major coal mine near Mt Pleasant in New South Wales, citing inadequate consideration of overseas greenhouse gas emissions under NSW law. The court ruled that the Independent Planning Commission failed to address 98% of the project’s emissions classified as “Scope Three,” which occur when exported coal is burned abroad. Environmental lawyer Anita Hart hailed it as a groundbreaking decision for climate law in Australia, while industry groups like the Minerals Council called for new legislation amid concerns over legal uncertainty and potential investor reluctance.

Story summary

In a landmark ruling, the High Court of Australia upheld a decision against the expansion of the Mount Pleasant coal mine in Musswellbrook, New South Wales. The court ruled unanimously that planning authorities must consider local climate change effects caused by emissions from exported coal when approving fossil fuel projects. In a 3-2 split decision, three judges found that the Independent Planning Commission failed to account for the greenhouse gas emissions generated when the mine's coal is sold and burnt overseas, effectively halting the expansion project which would have doubled the mine’s output to 21 million tonnes per annum until 2048. Environmental campaigners hailed this as a binding national precedent, urging planning authorities across Australia to take similar climate impacts into account for future fossil fuel projects. The case was initiated by local residents and environmental groups like DAMSHEG (Denman Aberdeen Muswellbrook Scone Healthy Environment Group), led by retired science teacher Wendy Wales, highlighting the growing concern over the environmental impact of coal mining in Australia.

tables → survive → Appeal

Edelman continued that “by focusing only upon two per cent of the project’s emissions”, the commission had failed to in its duty to fully consider minimisation conditions. asserted
commission → continue → conditions
