Removing business and first class seats could cut aviation emissions by up to 57%, according to a University of Oxford study.
A new study by the University of Oxford finds that eliminating business and first class cabins could reduce aviation’s climate impact by up to 57%, with reconfiguring planes for more economy seats cutting emissions significantly.
The research, analyzing 2023 flight data, shows emissions vary widely—ranging from under 50 to over 800 grams of CO₂ per passenger-kilometre—due to inefficiencies in current layouts and aircraft use.
Replacing older planes with newer, more efficient models like the Boeing 787-9 and Airbus A321neo could lower global emissions by 27% to 34%.
The study highlights that frequent long-haul travel by wealthier passengers drives disproportionate emissions, and simple changes in seating and operations offer major near-term climate benefits.
