The Best Carbon Offsets – QAS-Certified

Only Clear, the Carbon Offset Company, Carbon Footprint and IATA have successfully submitted their carbon offsets to be audited against the high standards required by the QAS.

IATA provides QAS-Certified offsets to several major airlines through its Carbon Offset Program. The organisation represents 240 airlines, or 84% of total air traffic, and leads the airline industry. Over 30 of its member airlines have introduced an offset program.

The best carbon offsets have met the stringent criteria set by the Quality Assurance Standard over the dates given below. They can be used by companies and organisations wishing to use the QAS Carbon Neutral Quality Mark.
