Quick Summary

A High Court ruling in New South Wales has determined that planning authorities must consider global climate impacts, including the emissions caused by exported fossil fuels (scope 3 emissions), when approving local projects. This decision has raised concerns among Western Australia's energy industry about potential impacts on future investments, particularly for large-scale proposals like Woodside’s $30 billion Browse gas project, which is still under review by state and federal environmental bodies. Industry leaders fear that such rulings could undermine investor confidence due to uncertainties around approval processes and the possibility of legal challenges.

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.
