The Civil Aviation Decarbonization Organization (CADO) and 4AIR announced a strategic collaboration between their respective Sustainable Aviation Fuel (SAF) registries. The collaboration's key focus is on interoperability to enhance data integrity, mitigate double issuance risks, and facilitate efficient cross-registry SAF certificate handling between commercial and business aviation. The collaboration between the CADO SAF Registry and the Assure SAF Registry powered by 4AIR is a key step towards a fully functioning SAF market while safeguarding data integrity. Alignment between commercial and business aviation sends a strong demand signal for more SAF, creates greater transparency, reduces integrity risks for the SAF value chain, and eases the burden of claiming SAF under voluntary or regulatory schemes," said Kennedy Ricci, President of 4AIR. "A unified approach from both business and commercial aviation is vital to create an environment that promotes SAF development and adoption across sectors.
