Approval demonstrates that ACR meets the high bar for quality in the global aviation carbon market
LITTLE ROCK, ARK – ACR is pleased to announce that at its October 2025 session, the Council of the International Civil Aviation Organization (ICAO), the United Nations’ main aviation body, approved ACR to supply carbon credits for the Second Phase of the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), covering the period 2027–2029.
The decision confirms that all of ACR’s active methodologies are eligible to supply credits for use in CORSIA’s Second Phase. This latest approval builds on ICAO’s previous decisions to recognize ACR-issued credits for CORSIA’s Pilot Phase (2021–2023) and First Phase (2024–2026).
“We are proud that ACR has once again successfully completed a thorough review of our program requirements and oversight and that ICAO has approved ACR-issued credits for use in both CORSIA’s First and now Second Phase,” said Mary Grady, Executive Director of ACR. “ICAO’s most recent approval reflects our ongoing alignment with Paris Agreement rules and ICAO requirements in a rapidly evolving market landscape.”
ICAO is a specialized agency of the United Nations that manages the standards that govern international aviation. In 2016, ICAO approved the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) as a global market-based mechanism to achieve carbon-neutral growth in international aviation starting in 2020. Demand for CORSIA Eligible offset credits is expected to be 1.5 billion tons of CO2-e through 2035.
