Transparency in the Paris Agreement

Establishing a credible and effective transparency system will be both crucial and a challenge for the climate regime based on pledge and review established in the Paris Agreement. The Agreement provides for review of achievements under national pledges (Nationally Determined Contributions or NDCs), but much of this information will become available only well after key steps in the launch of this latest attempt to control human influence on the climate. Still, in these early years, information and understanding of individual and collective performance, and of relative national burdens under the NDCs, will play an important role in the success or failure of the Agreement. However, because of the phasing of various steps in the 5-year cycles under the Agreement and the unavoidable delays of two or more years to produce and review government reports, the Climate Convention and other intergovernmental institutions are ill suited to carry out timely analyses of progress. Consequently, for better or worse, in advance of formal procedures, academic and other non-governmental groups are going to provide analyses based on available data and their own methodologies. We explore this transparency challenge, using the MIT Economic Projection and Policy Analysis (EPPA) model, to construct sample analyses and consider ways that efforts outside official channels can make an effective contribution to the success of the Agreement.
