Jet2's emissions are rising 20% over two years despite intensity improvements. Absolute decarbonisation is absent: all targets are intensity-based, SAF adoption is negligible at 1%, and water and biodiversity impacts go unreported. The airline is locked into fossil fuel dependency with no credible near-term pathway out.
Same formula for every company. No curve. No private weighting.
