4AIR, the global leader in business aviation sustainability, announced today that it has helped aircraft owners, operators, and passengers offset or reduce more than 6.2 million metric tons of CO2 through the use of verified carbon offsets and sustainable aviation fuel (SAF) since launching in November 2020. SAF is a “drop-in” fuel that meets all the same technical and safety requirements as fossil-based jet fuel but comes from a more sustainable source.
