4Air registers 10m SAF gallons on Assure platform

Business aviation sustainability company 4Air said it has successfully registered 10m gallons of sustainable aviation fuel (SAF) on its blockchain-backed ledger Assure SAF Registry.

“The Assure SAF Registry is more than just a tracking tool; it is a foundational element for the future of sustainable aviation,” said Nancy Bsales, chief operating officer at 4AIR. “By providing a secure, transparent, and verifiable system, we are building the infrastructure necessary to scale SAF adoption across the industry.”

Assure SAF Registry provides a inventory and registry system for both business and commercial aviation value chains, building on 4AIR’s experience in tracing and documenting SAF.

This ensures traceability from producer to supplier, to the fixed base operator (FBO), airline, and ultimately to the corporate end-user, providing a detailed history for even the smallest quantity of SAF.

The blockchain technology gives assurance to prevent double claims or counting, delivering a true understanding of SAF usage and its impact, and increasing confidence in aviation sustainability efforts.

4Air said that the Assure SAF Registry is designed to assist with easing tracking requirements for both voluntary and regulatory reporting.
