Overview 
WASHINGTON – Nov. 11, 2025 | Verra’s Verified Carbon Standard (VCS) Program has been approved by the International Civil Aviation Organization (ICAO) to supply eligible emission units for use in the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) during its second phase, first compliance period (2027–2029).
The decision reaffirms the VCS Program’s standing as one of the most trusted and rigorously governed carbon credit programs globally.
Mandy Rambharos, CEO, Verra
The decision confirms the continued eligibility of Verified Carbon Units (VCUs) under CORSIA. Under the second phase of CORSIA, the following VCUs are approved if they meet all other eligibility conditions as applicable:
- VCUs from projects that began crediting from January 1, 2016
- VCUs issued for reductions or removals that occurred between January 1, 2021, and December 31, 2029
This announcement follows ICAO’s previous approvals of the VCS Program for both the CORSIA pilot phase (2021–2023) and first phase (2024–2026).
The decision also reverts the following exclusions/restrictions from earlier approvals:
- ICAO has removed the exclusion of VCUs from projects applying methodologies AMS.II.G.: Energy efficiency measures in thermal applications of non-renewable biomass (external) and VMR0006 Energy Efficiency and Fuel Switch Measures in Thermal Applications (for improved cookstove activities). This change applies to the VCS Program’s eligibility for CORSIA’s second phase but has also been retroactively extended to the first phase (2024–2026).
- Similarly, the exclusion of VCUs from projects applying VCS methodology VM0049 Carbon Capture and Storage has been removed for certain projects, signaling growing momentum for high-integrity engineered removal activities.
Note: Verra will soon release an updated CORSIA Label Guidance document.
