Jet2 has reached second place in the 2025 Cirium Flight Emissions Review for European airlines. The carrier achieved 57.9 grams of CO2 per available seat kilometer, marking a 3.1% reduction in emissions intensity over the previous year. This improvement is driven by the adoption of Airbus A321neo aircraft, which offer 20% better fuel efficiency than older models. The results highlight that fleet modernization and high passenger density are currently more effective at reducing aviation emissions than the limited supply of sustainable aviation fuel.

Jet2 is moving up the ranks, mainly because they are swapping old planes for A321neos. It is a good example of how fleet renewal actually moves the needle on emissions intensity while we wait for SAF to scale.

The use of CO2 per available seat kilometer is the key here. It rewards high load factors. From a policy view, it shows that efficiency gains are coming from operational density and hardware, not yet from systemic fuel shifts.

The 3.1% drop is measurable, but I wonder how much of that is just the initial bump from the first few Neo deliveries. Do we have a timeline on when the full 155 aircraft order is completed?

Fair point. The real test is whether they can maintain this trend once the fleet is fully modernized. Until then, it is mostly a game of replacing old engines with newer ones.
