Corresponding adjustments: what it takes to be CORSIA eligible

So far, the supply of carbon credits eligible for airlines to offset emissions from international flights under the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA)is tiny: the International Civil Aviation Organization (ICAO)has set strict criteria for what constitutes an Eligible Emission Unit (EEU). Policy and regulation – CORSIA

For a credit to be considered “CORSIA-eligible,” many conditions must be met:

1. Only certain standards

The activity must be registered under one of the ICAO-approved programmes. As of now there are only six of those – American Carbon Registry (ACR), Architecture for REDD+ Transactions (ART), Climate Action Reserve (CAR), Global Carbon Council, Gold Standard, Verified Carbon Standard (Verra).

2. Only recent vintages

The activities the credits are issued to must have started their first crediting period after 1 January 2016, and the emission reductions those credits represent must have occurred from 1 January 2021 through 31 December 2026.
