Jet2 has been recognised as one of Europe's most fuel-efficient airlines in a major independent global aviation emissions study, published by aviation data specialist Cirium.
In Cirium's 2025 Flight Emissions Review, which assessed the emissions performance of the world's 100 largest passenger airlines, Jet2 ranked second in Europe for carbon efficiency, measured as CO₂ emissions per Available Seat Kilometre (ASK), a standard industry metric that reflects emissionsrelativeto passenger capacity.
Cirium's analysis shows Jet2 achieved 57.9 grams of CO₂ per ASK in 2025, supported by continued efficiency improvements year-on-year. Jet2 also recorded a 3.1% reduction in emissions intensity compared with the previous year,demonstratingongoing progress in reducing the carbon impact per passenger flown.
With an order for 155 Airbus A321neo aircraft, delivering more than 20% fuel efficiency improvements compared with previous-generation aircraft, Jet2 expects these performance metrics to strengthen further over the coming years as newer aircraft continue to enter the fleet.
Paul Southall, Head of Sustainability at Jet2, said: "We are pleased to see Jet2 recognised by Cirium as one of the most carbon-efficient airlines in Europe. This independent analysis reflects the practical steps we are taking to as part of our sustainability journey, alongside continued investment in more efficient aircraft and operational improvements across our business."
He added: "This report reinforces an important point: while sustainable aviation fuel will play a critical long-term role, real emissions reductions today are being driven by fleet decisions, how aircraft are configured, and how airlines operate day-to-day. Independent benchmarking like Cirium's is vital for transparency and accountability."
The Cirium Flight Emissions Review uses the EmeraldSky methodology, applying a single, consistent approach across the global airline industry and independently assured under ISAE 3000 standards by PwC. It is designed to allow fair comparisons between airlines ofdifferent sizes, businessmodelsand geographies.
