- Guyana, Madagascar, the United Kingdom, Zambia, and Zimbabwe joined the alliance.
- IETA, Airbus, Sylvera, and the Verified Carbon Market Collaborative became supporting partners.
- Aviation demand for CORSIA carbon credits could reach 250 million units by 2027.
- The initiative helps countries access carbon markets and climate finance.
- The alliance supports aviation’s pathway toward net-zero emissions.
- Governments and industry groups are working together to increase carbon credit supply.
- The initiative supports implementation of international carbon market mechanisms.
Governments and Industry Expand CORSIA Support
The International Air Transport Association (IATA) has announced that participation in the Supporting Alliance for CORSIA Eligible Emissions Unit (EEU) Supply has reached 50 participating entities, marking a significant milestone in efforts to expand the availability of high-quality carbon credits for the aviation sector.
The latest expansion includes several national governments and leading organizations across the carbon market value chain, reflecting growing international support for the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA).
The alliance seeks to ensure that sufficient carbon credits are available as airlines prepare for increasing compliance requirements under the global aviation emissions framework.
New Governments Join the Alliance
Five countries have officially signed the Aviation Carbon Market Compact and joined the alliance:
- Guyana
- Madagascar
- United Kingdom
- Zambia
- Zimbabwe
Several additional governments, including Peru, have also expressed interest in participating.
The involvement of governments is considered essential because countries play a critical role in authorizing carbon credits and ensuring that international carbon market activities align with national climate commitments.
By joining the alliance, these countries gain access to technical support, market expertise, and opportunities to participate more actively in global carbon markets.
Industry Partners Strengthen Collaboration
The alliance has also expanded its private sector and industry participation.
New supporting organizations include:
- International Emissions Trading Association (IETA)
- Verified Carbon Market Collaborative
- Sylvera
- Airbus
These organizations are contributing technical knowledge, financial support, market expertise, and policy guidance to help expand the supply of eligible carbon credits.
Their participation strengthens collaboration across the aviation, finance, and carbon market sectors.
Growing Demand for CORSIA Credits
Industry forecasts suggest that demand for CORSIA Eligible Emissions Units could reach between 225 million and 250 million units by spring 2027.
As international aviation continues recovering and airline emissions increase, demand for eligible carbon credits is expected to rise substantially.
The alliance was established to help address this challenge by:
- Increasing carbon credit supply.
- Providing technical assistance.
- Supporting policy implementation.
- Facilitating market access.
- Improving climate finance opportunities.
The initiative aims to ensure that sufficient high-quality credits become available to meet future demand.
Supporting Countries and Carbon Markets
One of the alliance’s key objectives is helping countries navigate the relationship between their Nationally Determined Contributions (NDCs) under the United Nations Framework Convention on Climate Change and the requirements necessary to authorize credits for CORSIA use.
Many countries face challenges related to:
- Carbon credit authorization.
- Market participation.
- Climate finance access.
- Regulatory frameworks.
- Carbon accounting systems.
The alliance seeks to provide practical support that enables countries to participate effectively in international carbon markets.

Industry Leaders Highlight Importance
Marie Owens Thomsen, IATA Senior Vice President Sustainability and Chief Economist, said the growing participation demonstrates strong commitment from both governments and industry stakeholders.
She noted that the involvement of new governments and supporting organizations strengthens the connection between market demand and policy frameworks.
According to Thomsen, these frameworks remain essential to unlocking the full potential of CORSIA-eligible emissions units and ensuring that sufficient credits reach the market at the required scale.
Carbon Markets Support Aviation Decarbonization
CORSIA was developed by the International Civil Aviation Organization (ICAO) as the aviation industry’s global market-based mechanism for addressing carbon emissions from international flights.
The system allows airlines to offset a portion of their emissions through approved carbon credits while the sector develops longer-term decarbonization solutions.
Carbon markets are expected to complement:
- Sustainable aviation fuels.
- More efficient aircraft.
- Operational improvements.
- Alternative propulsion technologies.
- Future zero-emission aircraft.
Industry organizations believe that carbon credits will remain an important component of aviation’s transition to net-zero emissions.
Broad Airline Participation
The alliance includes several major airline groups and aviation companies.
Participating airlines include:
- Air France-KLM
- Lufthansa Group
- Qatar Airways
- Singapore Airlines
- Japan Airlines
- International Airlines Group
- SWISS
- ANA
- Egyptair
- Pegasus Airlines
Their participation helps ensure that carbon market development remains aligned with airline requirements and future compliance needs.
Outlook
The expansion of the CORSIA Supporting Alliance demonstrates growing international commitment to strengthening carbon markets for aviation. As more governments, airlines, financial institutions, and carbon market organizations join the initiative, the supply of high-quality emissions units is expected to increase.
With demand for CORSIA-eligible credits projected to rise significantly by 2027, effective collaboration between governments and industry participants will become increasingly important. The alliance may play a critical role in supporting aviation’s decarbonization efforts, expanding access to climate finance, and helping countries participate more effectively in international carbon markets.
