This paper analyses the Nationally Appropriate Mitigation Actions (NAMAs) that non-Annex I Parties pledged to the UNFCCC in compliance with Appendix II provisions of the Copenhagen Accord. The purpose of the analysis is to suggest an effective framework for delivering international financial, technology, and capacity building support as well as a measuring, reporting, and verifying (MRV) GHG emission reductions. The paper shows NAMAs can be divided into four groups: 1) enabling conditions; 2) projects, programs and sectoral measures; 3) carbon neutrality; and 4) national GHG emission reduction targets. The diversity in NAMAs reflects the diverse mitigation needs of non-Annex I Parties and thus calls for a “layering” approach to international support and MRV for NAMAs. This paper further identifies remaining designing issues for an MRV framework by exploring what needs to be incorporated in guidelines for MRV and International Consultations and Analysis (ICA) to be adopted by COP.
