Options for improving the emission unit eligibility criteria (EUCs) under the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA)

This discussion paper evaluates the Emission Unit Eligibility Criteria (EUCs) for the International Civil Aviation Organization's (ICAO) Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), proposing refinements to five key quality criteria to ensure environmental integrity.

• The current EUCs generally cover basic conceptual elements for carbon offset credit integrity, but require more detailed elaboration on program requirements and procedures to be effectively realized.
• The paper recommends specific improvements for additionality and baseline determination, including the exclusion of project types that are legally required or profitable without offset revenues, and the requirement that baselines use vetted, program-approved methodologies with conservative parameters tailored to specific sectors and geographies.
• To improve permanence, the paper suggests defining a 100-year permanence threshold, utilizing buffer reserves or temporary crediting, and holding project owners liable for intentional reversals.
• Recommendations for avoiding double counting include specifying procedures to prevent double issuance, use, and claiming, and expanding the definition of double claiming beyond host country claims. For 'no net harm', the paper suggests establishing social and environmental safeguards and removing the word 'net' from the EUC text.
