Quick Summary

Australia’s highest court ruled against expanding the Mount Pleasant coal mine in New South Wales, stating that the approval process failed to minimize greenhouse gas emissions as required by law. The case was brought by environmental activists Wendy Wales and Tony Lonergan who argued that mining operations contribute significantly to climate change impacts. Three judges out of five agreed with the plaintiffs, halting the proposed expansion which would have extended the mine’s operation until 2048 and nearly doubled its annual output. This decision sets a national precedent requiring consideration of climate damage in fossil fuel project approvals.

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.
