4Air has signed its 100th client, the aviation sustainability consulting firm said Thursday. The company delivers sustainability programs dedicated to aviation, providing what it calls a simplified and verifiable path for aircraft operators to reduce their carbon footprint.

Since 4Air’s launch in January 2021, it has offset or reduced more than 2.5 million tonnes of CO2 emissions through the use of verified carbon offset credits and sustainable aviation fuel (SAF). In just over two years, the company has provided accounting and documentation for the physical and book-and-claim use of more than 5.8 million gallons of SAF.
