牛津大学的一项新研究发现,消除商业舱和头等舱可以将航空对气候的影响降低高达57%,为更多经济座椅重新配置飞机可以大大减少排放量。 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. 分析2023年飞行数据的研究显示,由于目前的布局和飞机使用效率低下,排放量差异很大,从每千公里不到50至800克二氧化碳不等。 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. 用更新、更高效的模型取代老式飞机,如波音787-9和空中客车A321neo,可以将全球排放量降低27%至34%。 Replacing older planes with newer, more efficient models like the Boeing 787-9 and Airbus A321neo could lower global emissions by 27% to 34%. 研究强调,富豪旅客频繁长途旅行导致排放量过高,座位和业务的简单改变可带来重大的近期气候惠益。 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.
