The Open-ended Working Group (OEWG) meets once mid-year and deliberates on issues to be further discussed and decisions to be adopted at the MOP/COP at the end of the year. The Open-ended Working group was established pursuant to decision I/5 of the First Meeting of the Parties to review reports of the Assessment Panels and prepare draft proposals for any amendments to the Protocol, among other things. Its mandate was extended pursuant to decision II/5 of the Second meeting of the Parties to consider other issues of relevance to the implementation of the Montreal Protocol.
