A Milestone for Sustainable Flight
When the international community adopted the Carbon Offsetting and Reduction Scheme for International Aviation in 2016 it created a single global framework for managing emissions from cross border flights. The latest decision by the Council of ICAO increases the pool of programmes able to supply CORSIA Eligible Emissions Units. Eight programmes will cover the first compliance cycle from 2024 to 2026. Another four have already been cleared for the second cycle running from 2027 to 2029, with more applications expected in 2026.
What the New Approvals Mean
· Airlines gain confidence that an ample volume of high quality credits will be available when surrender obligations begin in 2025
· Competition among registries can lower transaction costs and stimulate innovation in monitoring and verification methods
· Governments can align their climate strategies by issuing a Letter of Authorization that removes any risk of double claiming under the Paris Agreement
· Project developers receive a predictable international outlet for credits, encouraging fresh investment in renewable energy and nature based solutions
Programme Breakdown
First cycle suppliers: American Carbon Registry, Architecture for REDD Plus Transactions, Climate Action Reserve, Global Carbon Council, Gold Standard, Isometric, Premium Thailand Voluntary Emission Reduction Program and Verified Carbon Standard. Second cycle suppliers to date: American Carbon Registry, Architecture for REDD Plus Transactions, Gold Standard and Verified Carbon Standard.
A Subtle but Powerful Insight
Because credits must be tagged with a governments authorization, the registry that can integrate national inventory data most seamlessly may become the preferred choice for airlines. This administrative efficiency could become as valuable as the underlying credit price, creating a new competitive dimension within voluntary carbon markets.
Conclusion
The expanded list of eligible programmes strengthens the operational readiness of CORSIA and reassures airlines, investors and states that practical tools exist to reach the sectors net zero target. Early engagement with authorised credits today can secure supply and reveal pricing advantages tomorrow.
