The International Air Transport Association (IATA) has launched the Supporting Alliance for CORSIA EEU Supply, a landmark coalition of over 32 aviation and carbon market stakeholders aimed at tackling critical supply bottlenecks in the global aviation carbon market.
The Alliance’s primary goal is to boost the availability of 225 to 250 million CORSIA Eligible Emissions Units (EEUs) by spring 2027.
As the industry approaches its first major compliance deadline under the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) in December 2027, the Alliance will focus heavily on bridging the gap between national climate goals and international aviation requirements.
Specifically, the Alliance will pool resources to provide pro bono, practical assistance to host countries navigating the complex administrative process of authorizing and transferring domestic carbon credits to the CORSIA market while satisfying their own Nationally Determined Contributions (NDCs) under the Paris Agreement.
Marie Owens Thomsen, IATA’s Senior Vice President Sustainability and Chief Economist, highlighted the economic and environmental stakes of the initiative: “CORSIA is the only globally agreed framework to address international aviation emissions… States, however, have their own obligations under the Paris Agreement and the UNFCCC. Credits must be transferred between these systems to avoid double-counting, which has become an important bottleneck.”
“The Supporting Alliance will provide implementation assistance to clear this and other bottlenecks that prevent credits from coming to the CORSIA market.
“It should be noted that CORSIA will likely generate $4-5 billion of climate finance in the first phase, and potentially $100 billion by 2035, depending on market prices. This will help fund climate action, support remote communities, and spur economic development.”
-
Target Bottlenecks: Pool participating organizations’ resources to offer tailored, practical, and pragmatic implementation assistance where supply chains are stalled.
-
Streamline Policy Interfaces: Assist national governments in managing the interface between their Paris Agreement NDCs and the authorization processes required for CORSIA-eligible credits under Article 6.2 guidance.
-
Expand Market Access: Improve developing nations’ access to international carbon markets, technical resources, and capital.
The Alliance will deploy recognized Article 6 and CORSIA experts to provide host countries with customized, on-demand support. This assistance will help governments manage ongoing reporting, authorization, and review processes, ensuring a robust, transparent supply of carbon credits ahead of the 2027 deadline.
The Alliance is open to all organizations and national governments willing to commit expertise and practical resources. The initial cohort features more than 32 entities, including a strong foundational coalition of global airlines: Air Asia, Air France-KLM, All Nippon Airways (ANA), Austrian Airlines, China Airlines, Corsair, Egyptair, IAG, Japan Airlines, KM Malta Airlines, Lufthansa Group, Pegasus Airlines, Qatar Airways, Scoot, Singapore Airlines, and SWISS.
