Transparency, Policy Surveillance, and the Comparison of Mitigation Efforts
Countries’ emissions mitigation pledges took many different forms under the 2015 Paris Agreement. This work highlights the role of transparency in understanding this variation and illustrates how economic tools can assess and compare mitigation efforts.
- Comparing mitigation efforts can play an important role in the Paris Agreement’s transparency mechanism. By enhancing the understanding of countries’ pledges and related mitigation efforts, these analyses can facilitate greater future ambition.
- With emissions mitigation pledges taking a variety of forms, economic tools can provide an “apples-to-apples” comparison of the emissions reductions, implicit carbon prices, and abatement costs of countries’ domestic mitigation programs.
- We review the results of four global models that present emissions, price, and cost metrics of mitigation efforts for major developed and developing countries, and compare these to the social cost of carbon and 2°C emission pathways.
- Countries’ mitigation programs will likely differ from the cost-effective, economy-wide carbon price assumed in most modeling analyses. We highlight key insights from the literature and place the details of countries’ mitigation programs in this context
- We discuss how to implement future modeling analyses to better represent the real-world details of national mitigation programs. This can refine comparability metrics and provide opportunities for policy learning.
