Airlines participating in the IATA carbon offset program typically offer carbon credits stemming from renewable energy or other high-quality projects that follow the stringent quality requirements of the Quality Assurance Standard (QAS).
Approved offsets must carry one of the following high-quality certificates:
- Certified Emission Reductions (CERs) - issued under the Clean Development Mechanism (CDM).
- Voluntary Emission Reductions (VERs) - Gold Standard or Voluntary Carbon Standard (VCS) version 2007 onwards.
- Approved REDD+ methodology projects - based on sustainable land use.
The following projects are not allowed to be offered under the IATA carbon offset program:
- Hydropower projects generating more than 20 megawatts.
- Projects using hydroflourocarbon-23 (HFC23).
- Forestry offset projects not based on sustainable REDD+ project methodologies.
