Jet2's emissions are rising 20% in two years despite intensity improvements, masking deterioration under a metric that lets growth hide. Supply chain visibility is incomplete, nature and water impacts go unreported, and net-zero targets are intensity-based—meaningless if absolute emissions climb. Lobbying through misaligned aviation bodies undermines stated climate commitments.
