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 Unvalidated intensity targets, withdrawn SBTi commitment, negligible SAF uptake (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. Scores are free. Companies can never pay for anything about their own score. Last verified July 2026.
