I found this very interesting concept.
“The book and claim system allows corporate consumers to buy SAF certificates (called SAFc) that represent the certified lifecycle emissions reductions from cleanly-fueled trips and then use them in corporate emissions reporting, with an auditable and credible trail of ownership. The completed transactions release funds into a solution that, if scaled and implemented for widespread use in planes, would achieve the desired decarbonization.”
It seems that the concept is still new.
