Tackling methane in the coal sector is a major opportunity for climate action that can also strengthen energy security. Experience shows that there are several steps countries can take today – using existing technologies and tools – that can lead to significant reductions in methane emissions from coal mining. This report highlights the lessons learned in different coal-producing jurisdictions to support the development of smart and effective methane regulation. It then provides detailed guidance on the process of designing, drafting and implementing new regulations. Finally, it discusses the different regulatory approaches currently in use for methane, with the aim of providing a comprehensive toolkit for policy makers.
