This paper focuses on a key question: whether both the developing countries generating the offsets and the developed countries buying them will be allowed to count the same emission reductions toward their respective pledges. The authors quantify the implications of double-counting of international offsets by building a spreadsheet model to analyze how potential offset supply and demand balances may evolve. They find that double-counting could effectively reduce the ambition of current pledges by up to 1.6 billion tons CO2e in 2020.
They close by describing several possible ways to address the risks of offset double-counting.

About SEI Working Papers:
The SEI working paper series aims to expand and accelerate the availability of our research, stimulate discussion, and elicit feedback. SEI working papers are work in progress and typically contain preliminary research, analysis, findings, and recommendations.
Many SEI working papers are drafts that will be subsequently revised for a refereed journal or book. Other papers share timely and innovative knowledge that we consider valuable and policy-relevant, but which may not be intended for later publication.
