Jet2's absolute emissions rose 20% in two years while intensity improved—a classic aviation greenwashing pattern. Unvalidated intensity targets, withdrawn SBTi commitment, negligible SAF uptake (<0.04% of fuel), and structural silence on non-CO2 warming effects define material weaknesses across climate and nature disclosure.
Jet2 scores 28/100 (Significant gaps) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified July 2026.
That places Jet2 joint 658th of 847 companies scored, and joint 4th of 23 in Airlines / Aviation.
