Methane mitigation potentials and related costs of China's coal mines.

ABSTRACT: Mitigating methane (CH₄) emissions from China's coal mines as the largest contributor to anthropogenic CH₄ emissions is vital for limiting global warming. However, the knowledge about CH₄ mitigation potentials and economic costs of Chinese coal mines remain poorly understood, which hinders the formulation of tailored CH₄ mitigation strategies. Here, we estimate and project China's provincial coal mine methane (CMM) emissions, mitigation potentials and costs under various coal production scenarios, by integrating the dynamic emission factors of CMM and key abatement technologies. We find that through continuous coal cuts and available CMM mitigation measures, China's CMM emissions can be reduced by 65%-78% (10.9 Tg-13.1 Tg) in 2060, compared with
