# SAFc

SAFc is an innovative system designed to promote the adoption of Sustainable Aviation Fuel (SAF) by issuing and managing SAF certificates. These certificates serve as verifiable proof that a specific volume of SAF has been produced or utilized, ensuring transparency and accountability in the aviation industry's transition to greener fuels.
