Offset credit supply potential for CORSIA

The International Civil Aviation Organisation is in the process of finalising the design of a scheme – the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) – to address carbon dioxide emissions from international aviation. In this discussion paper estimate the potential supply of carbon offset credits to meet demand from international aviation under CORSIA under a number of different scenarios which include different types of restrictions imposed on the eligibility of offset credits. Analysis considers supply from the four largest offsetting programmes: the Clean Development Mechanism, the Verified Carbon Standard, the Gold Standard and the Climate Action Reserve for emission reductions over the period from 2013 – 2035.
