The Civil Aviation Decarbonization Organization (CADO), 123Carbon, and the Assure SAF Registry have agreed to collaborate on implementing an interoperability pilot program between their respective Sustainable Aviation Fuel (SAF) registries. The goal is to exchange verified information on the integrity of SAF attributes and strengthen their global adoption.

The initiative seeks to establish shared controls and standards to eliminate the risk of double counting and maintain a single, reliable record of SAF-related emissions reduction declarations. Registry integrity is considered essential for market expansion, especially in a context characterized by fragmentation and customized structures that hinder rapid implementation.

CADO emphasized that harmonization, standardization, and increased transparency are necessary conditions for consolidating a mature SAF market. For its part, 123Carbon noted that interoperability will enable the creation of an open, peer-to-peer technology ecosystem without adding extra layers of governance, and will also facilitate the future transfer of certificates between registries.

Meanwhile, 4AIR—through the Assure Registry—emphasized the importance of implementing shared safeguards that allow for the verification of SAF attributes across registries, the early identification of duplication risks, and the preservation of the credibility of voluntary and regulatory claims as the market continues to expand.

The pilot program represents an initial step toward greater interoperability within the SAF ecosystem, with the goal of strengthening trust, improving transparency, and supporting the effective decarbonization of the aviation sector.
