Exploring negative emission potential of biochar to achieve carbon neutrality goal in China

The latest study published in Nature Climate Change explores the significant methane mitigation potential achievable through the strategic closure of gas-rich coal mines in China. By constructing a detailed and dynamic coal mine database, they estimate that China’s coal methane emissions have been largely underestimated. The findings suggest that adopting a closure strategy prioritizing high-gas-content mines, as opposed to the current scale-based approach, could reduce cumulative methane emissions by 67 Tg (26%) by 2050, potentially reaching a reduction of 100 Tg (39%) with improved methane recovery practices. This targeted approach presents a promising strategy for aligning coal phase-out policies with enhanced methane emission mitigation.
