In New South Wales, the approval and subsequent legal challenges of coal mine expansions have highlighted tensions between economic interests and climate obligations. The New South Wales Independent Planning Commission (IPC) approved the Hunter Valley Operations (HVO) Continuation Project, a joint venture between Yancoal and Glencore. This expansion, the largest in the state’s history, allows for the extraction of 716 million tonnes of coal. While the IPC determined that economic benefits and job preservation outweighed environmental impacts, the approval mandated strict conditions regarding greenhouse gas emissions and carbon offsets. Environmental groups criticized the decision as a “betrayal” of climate policy. Following this, the High Court of Australia issued a landmark ruling that halted the expansion of the Mount Pleasant coal mine. In a 3-2 split decision, the court found that the IPC failed to adequately consider how Scope 3 emissions—pollution from exported coal—contribute to local climate risks such as bushfires, droughts, and flooding. This ruling establishes a national precedent requiring decision-makers to account for the local climate consequences of a project’s emissions, potentially impacting numerous other coal proposals in the NSW planning pipeline. The High Court has since upheld this ruling, invalidating the expansion of the Mount Pleasant mine. The legal challenge, brought by local residents Wendy Wales and Tony Lonergan of the Denman Aberdeen Muswellbrook Scone Healthy Environment Group, confirms that decision-makers must account for the regional impacts of Scope 3 emissions. This decision directly affects 17 coal proposals currently in the NSW planning pipeline. Consequently, the expansion approval for MACH Energy, which sought to nearly double annual output and extend the mine's life by 22 years, must be referred back to the NSW Land and Environment Court or the IPC for a proper assessment of its climate impact.
