Australian High Court rules Scope 3 emissions must be considered in coal mine approvals

An October 2026 ruling by Australia's High Court requires the NSW Independent Planning Commission to reconsider Scope 3 emissions from the Mt Pleasant coal mine expansion. Scope 3 covers emissions released when exported coal is burned overseas. The decision in MACH Energy Australia Pty Ltd v Denman Aberdeen Muswellbrook Scone Healthy Environment Group Inc sent the approval back on process grounds, not on a finding that coal must end. The Spectator Australia piece by Gabriël Moens and John McRobert calls the ruling a roadblock and argues that CO2 is not a climate threat. Most of the article is an opinion attack on climate science and net zero policy. The part worth tracking for carbon markets is the legal precedent: Australian planning authorities now have to show they assessed downstream emissions from state significant fossil fuel projects.

The actual ruling is narrower than the headline. It says the NSW planning commission had to consider whether Scope 3 emissions were minimised to the greatest extent practicable. That is a process point, not a ban on coal. The authors frame it as climate ideology, but the legal question is statutory interpretation.

Worth separating the legal outcome from the CO2 commentary. The High Court did not declare coal illegal. It sent the approval back on process because the commission ignored a statutory factor. Whether you accept climate science or not, that is how administrative law works.

Scope 3 emissions are the emissions from burning exported coal, not from the mine's own operations. This ruling could make future Australian coal approvals harder to wave through. But the article's scientific claims about CO2 do not match the IPCC consensus, so treat those sections as opinion.

The interesting part for carbon markets is that Scope 3 accounting just became part of Australian planning law for state significant projects. That creates legal risk for new coal and gas projects. The hoax framing is a distraction from the actual compliance question.
