The IATA Aviation Carbon Exchange, or ACE, is a centralized marketplace for CORSIA eligible emission units where airlines and other aviation stakeholder can trade CO2 emission reductions for compliance or voluntary offsetting purposes. The ACE technology provides for an easy to use and secure trading environment, offering the highest level of transparency in terms of price and availability of emissions reductions. Airlines trading on ACE will benefit from IATA Settlement Systems and Clearing House for seamless and risk-free settlement of funds. The exchange is open to all airlines, IATA and non-IATA, as accessible to carbon market participants wanting to list emissions reduction that are CORSIA compliant.

The ACE platform is offered in partnership with Xpansiv CBL Holding Group. The roll out of the different trading options will be done in a phased approach and the full integration of CBL Markets’ trading platform and IATAs settlement systems is planned for Q2020. 

On January 30, 2020 — Xpansiv CBL Holding Group (XCHG) and IATA announced a partnership to develop the Aviation Carbon Exchange (ACE), a new and innovative way for airlines to meet their emissions compliance obligations under the Carbon Offset Reduction Scheme for International Aviation (CORSIA). CORSIA addresses the increase in total CO2 emissions from international aviation above 2020 levels.

Powered by CBL Markets, an XCHG company, ACE will serve as a centralized marketplace for CORSIA eligible emission units, providing a secure, intuitive destination for airlines to access real-time data with full price transparency. In Q1 2020, CBL Markets and IATA plan to trial with airlines that want to start offsetting voluntary credits as a pilot phase. The CORSIA eligible emission units will be listed on ACE once ICAO has published those accepted under the scheme. ACE trading will be supported by the well-established IATA Settlement System and Clearing House, offering seamless and risk-free settlement to IATA and non-IATA airlines.

The partnership foresees a phased approach in terms of rolling out the different trading options, with the full integration of CBL Markets’ trading platform and IATAs settlement systems to be expected during the 3rd quarter of 2020.
