Letter from the International Coalition for Sustainable Aviation to the ICAO Council on the Adoption of the Emissions Unit Criteria (EUCs) in Order to Address Double-Counting and Increase CORSIA

The International Coalition for Sustainable Aviation (ICSA) advocates for the strict adoption of the Emissions Unit Criteria (EUCs) to maintain the environmental integrity of CORSIA. The coalition warns that allowing double-counted emissions credits—where reductions are claimed by both airlines and host countries—would increase global emissions. ICSA recommends a vintage date restriction for eligible units to projects starting in 2020 or later to avoid the use of low-quality accumulated credits. Additionally, the letter demands greater transparency for the Technical Advisory Body (TAB), including public membership lists, conflict-of-interest declarations, and open meetings to prevent secret deals and ensure fair program eligibility assessments.

• The Emissions Unit Criteria (EUCs) are essential for the environmental integrity of CORSIA, and any weakening of these criteria, particularly regarding the avoidance of double counting, could compromise the entire scheme.
• Double counting occurs when emissions reductions are claimed by both an airline and the host country; ICSA argues this must be prohibited regardless of whether the reductions fall within a host country's nationally determined contribution (NDC) under the Paris Agreement.
• To prevent the use of low-environmental-quality credits accumulated before 2020, ICSA recommends a vintage restriction limiting eligibility to projects with a start date of 2020 or later.
• The Technical Advisory Body (TAB) requires significant transparency reforms to avoid conflicts of interest and 'secret back-room deals,' including public membership lists, public conflict-of-interest declarations, and open meetings.
