High Court ruling: NSW coal mine expansion must assess Scope 3 emissions
katherinetimes.com.auAustralia's High Court has ruled that a proposed expansion of the Mount Pleasant coal mine in NSW must take account of Scope 3 emissions, the pollution released when exported coal is eventually burned. The 3-2 decision upholds an earlier court ruling that the state's planning commission failed to consider conditions to reduce those downstream emissions. The case was brought by Hunter Valley residents and has been described as a landmark for climate litigation in Australia. The ruling creates new uncertainty for coal miners and investors. Future project approvals in NSW may now need to assess emissions from export customers, and could face conditions such as coal washing, restricting sales to Paris Agreement signatories, or offsetting expected Scope 3 emissions. The mine's 22-year expansion plan now goes back to the NSW Land and Environment Court, while a stop-gap approval lets it operate until 2032. The decision is likely to be studied by courts and regulators in other countries.
