For certifying entities spending $1000 or less on Sustainable Aviation Fuel (SAF) credits, proof of retirement is strongly encouraged, but not required. The lack of availability for full retirement documentation is occurring because small volume purchases are typically retired in bulk, and retirement certificates are not provided to every buyer.
This waiver is a reflection of the state of the SAF market and our intention to encourage all buyers to participate in it. We aim to reassess this waiver as the market continues to evolve and SAF producers & brokers converge around registries with more accessible documentation.
