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

The High Court in Australia ruled that planning authorities must consider local climate change impacts from global greenhouse gas emissions when approving fossil fuel projects. In a 3-2 split decision, the court dismissed MACH Energy's appeal against a New South Wales Court of Appeal ruling that halted the expansion of its Mount Pleasant coal mine near Muswellbrook. The case was brought by environmental advocates who argued that planning authorities failed to account for "scope 3" emissions — those caused when exported coal is burned overseas. The court found that such emissions must be minimized as much as possible under New South Wales planning law, setting a precedent expected to influence future fossil fuel project approvals across the country.

tables → survive → Appeal
The High Court on Wednesday upheld the lower court’s decision, but on a different basis. asserted

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
