Climate-heating emissions from aviation could be slashed in half – without reducing passenger journeys – by getting rid of premium seats, ensuring flights are near full and using the most efficient aircraft, according to analysis.

These efficiency measures could be far more effective in tackling the fast-growing carbon footprint of flying than pledges to use “sustainable” fuels or controversial carbon offsets, the researchers said. They believe their study, which analysed more than 27m commercial flights out of approximately 35m in 2023, is the first to assess the variation in operational efficiency of flights across the globe.

The amount of carbon dioxide per kilometre flown has been falling as aircraft become gradually more fuel efficient. However, the growth in the number of flights has far outstripped this, meaning the emissions helping to fuel the climate crisis are rising. Aviation’s carbon dioxide emissions could double or even triple by 2050, according to experts.

The new analysis found that more polluting flights were common from airports in the US and Australia, particularly smaller ones, as well as in parts of Africa and the Middle East. Airports in India, Brazil and south-east Asia were dominated by less polluting flights.
