Airline Environmental Audit
The QAS has been auditing environmental performance for the airlines since 2012. Its Carbon Offsetting Standard is the most stringent in the world and used by IATA for its own Carbon Offset Program.
QAS for Airlines
Participating airlines are audited annually against the tightest set of rules worldwide, including at least 40 criteria such as emissions factors, calculation methodologies, project methodologies, registry retiral, radiative forcing index, Green Claims compliance, pricing and providing accurate information. Airlines with their own carbon offset programs can apply directly to the QAS to have their offsets audited, certified and awarded the QAS Quality Mark, or alternatively IATA can both set up the carbon offset program and handle the QAS application as responsible provider.
