At its sixth session held on 17-18 November 2003 the Ad Hoc Group of Experts on Coal in Sustainable Development addressed the subject of Coal Mine Methane (CMM). Following the two background papers (ENERGY/GE.1/2003/4 and ENERGY/GE.1/2003/5) as well as a number of presentations treating on that matter delivered during the session, the secretariat put forward a proposal for establishment of the Ad Hoc Group of Experts focusing on CMM. It was noted that activities in the area in question would offer the opportunity for the Group to address not only the three pillars of sustainable development, notably economic, environmental and social, but also the image of coal (see para. 22 of the Ad Hoc Group of Experts on Coal in Sustainable Development’s 6th Session Report).
The Committee on Sustainable Energy at its fourteenth session held on 27-30 June 2005 endorsed both, the establishment of the Ad Hoc Group of Experts on Coal Mine Methane, as well as the program of its work (see section XI point (f) of the Committee’s 14th Session Report).
At its nineteenth session held on 24-26 November 2010, the Committee "approved that a recommendation be made to the Executive Committee of the UNECE to change its name to the Group of Experts on Coal Mine Methane" (ECE/ENERGY/84 para. 26(b))
At the sixteenth session held on 3-4 March 2021, "[n]oting the request of the Committee on Sustainable Energy at its twenty-ninth session that its expert groups consider in their work the changing social, environmental, and economic contexts for their activities and the principles of a just transition, the Group of Experts agreed to revise its mandate and work to orient them with the 2030 Agenda for Sustainable Development and embrace the principles of a just transition (para. 27, ECE/ENERGY/GE.4/2021/2). The proposed revision is to be presented for the Committee's approval at its 30th session on 22-24 September 2021.
