Options for Improving the Emission Unit Eligibility Criteria under the Carbon Offsetting and Reduction Scheme for International Aviation

This discussion paper assesses options for improving the current EUCs. Clearly articulated EUCs are needed to define minimum standards for the “quality” of carbon offset credits that may be used under CORSIA. High quality offset credits will ensure the environmental integrity of CORSIA, meaning that global GHG emissions will be no higher under CORSIA than if airlines were to meet their emissions limitation goals without using offset credits. The paper can inform future revisions of the EUCs that are envisaged with  the view to improve and refine them over time.
