This document provides a list of concrete ideas for actions that could scale up projects on the capture and use of methane at coal mines. The list is based on need statements and ideas proposed during the 21-22 March 2023 GMI Coal Mines Subcommittee meeting, held in partnership with the United Nations Economic Commission for Europe (UNECE). Nearly 50 representatives from 15 countries attended the Subcommittee meeting, including policymakers, technology providers, coal mining industry, academia, international non-government organizations, and environmental think tanks. Participants brainstormed potential solutions (notes available here) to top barriers to mitigating coal mine methane, identified at a prior meeting on September 27, 2022 (notes available here). The Coal Mines Subcommittee subsequently reviewed the list of ideas to prioritize actions GMI could focus on to most effectively address barriers in the coal sector.
