Jet2 recognized as one of Europe’s most economical airlines in independent global research | News
Jet2 has been recognized as one of Europe’s most fuel-efficient airlines in a major independent study into global aviation emissions 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 Kilometer (ASK), a standard industry metric that reflects emissions relative to passenger capacity.
Cirium’s analysis shows that Jet2 achieved 57.9 grams of CO₂ per ASK in 2025, supported by continued year-on-year efficiency improvements. Jet2 also recorded a 3.1% reduction in emissions intensity compared to the previous year, demonstrating continued 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 to previous generation aircraft, Jet2 expects these performance data to improve further in 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 recognized by Cirium as one of the most carbon-efficient airlines in Europe. This independent analysis reflects the practical steps we are taking as part of our sustainability journey, alongside continued investment in more efficient aircraft and operational improvements across our business.”
He added: “This report underlines an important point: while sustainable aviation fuel will play a critical role in the long term, today’s actual emissions reductions are determined by fleet decisions, the way aircraft are configured and how airlines operate on a daily basis. Independent benchmarking like Cirium’s is critical for transparency and accountability.”
The Cirium Flight Emissions Review uses the EmeraldSky methodology, which delivers a single, consistent approach applied across the global aviation sector and independently guaranteed under ISAE 3000 standards by PwC. It is designed to enable fair comparisons between airlines of different sizes, business models and geographies.
