Sustainability In The Airline Industry Statistics 2026

Aviation cut CO2 emissions intensity by 34% from 2005 to 2019, yet climate impact is not just about CO2, with contrails and induced cirrus linked to about 0.3% of global warming potential in some estimates. At the same time, EU rules like ReFuelEU Aviation turn SAF and emissions performance into a measurable compliance value per kg CO2e reduced, while CORSIA and EU ETS keep pushing stronger MRV and lifecycle accounting across international travel. Between route planning gains, lifecycle reductions from fuels, and tightening reporting duties such as CSRD and GHGRP, the sustainability picture is moving fast and uneven, and the stats reveal where progress is real and where the hard work still sits.
