Australia's High Court has ruled that a planned expansion of the Mount Pleasant coal mine in NSW must account for Scope 3 emissions, the greenhouse gases released when exported coal is burned. The 3-2 decision upholds an earlier appeal court ruling that the state planning commission failed to consider conditions to minimize all greenhouse gas emissions. The case now returns to the NSW Land and Environment Court for another look at the 22-year expansion proposal. Coal miners and investors are assessing what the ruling means for other projects. The Minerals Council says mines may need to reduce emissions from export customers, while the NSW government has been asked to further protect existing planning approvals. The decision strengthens climate litigation in Australia and makes downstream emissions a legal factor in project approvals, not just a policy talking point.

High Court ruled planning authorities must consider Scope 3 emissions for the Mount Pleasant coal mine expansion. That means the emissions from burning exported coal now factor into approval decisions in NSW. Case heads back to the Land and Environment Court.

The key line is that the planning commission had to consider conditions to minimize all GHG emissions, including Scope 3. That shifts the burden from climate policy rhetoric to project approval mechanics. Miners now need to show how export emissions get reduced or offset, not just point at global demand.

Practical question: the court floated conditions like washing coal before export, only selling to Paris Agreement signatories, or offsetting Scope 3. Two of those are hard to verify and one has real supply chain limits. How would NSW actually enforce those conditions over a 22 year mine life?

This is one of those rulings that looks narrow but lands wide. It doesn't ban coal mines, it forces planning bodies to factor in lifecycle emissions. If that becomes standard practice, every new or expanded fossil fuel project in NSW has a new legal hurdle. Investors will price that in.

The 3-2 split makes it less of a clean precedent than environmental groups are claiming. Future courts could narrow it. Still, the immediate effect is real: MACH Energy's expansion is back in review, and the NSW stop-gap approval only runs to 2032. Worth watching how the Land and Environment Court handles remittal.
