Abstract

Commercial aviation’s contribution to climate change is growing, but the global role of private aviation is not well quantified. Here we calculate the sector’s CO2 emissions, using flight tracker data from the ADS-B Exchange platform for the period 2019 to 2023. Flight times for 25,993 private aircraft and 18,655,789 individual flights in 2019-2023 are linked to 72 aircraft models and their average fuel consumption. We find that private aviation contributed at least 15.6 Mt CO2 in direct emissions in 2023, or about 3.6 t CO2 per flight. Almost half of all flights (47.4%) are shorter than 500 km. Private aviation is concentrated in the USA, where 68.7% of the aircraft are registered. Flight pattern analysis confirms extensive travel for leisure purposes, and for cultural and political events. Emissions increased by 46% between 2019-2023, with industry expectations of continued strong growth. Regulation is needed to address the sector’s growing climate impact. Carbon dioxide emissions from private aviation increased by 46% between 2019 and 2023, with almost half of flights covering less than 500 km in distance, according to an analysis of flight tracking data.

私人航空对气候变化的影响越来越大
商业航空对气候变化的影响越来越大,但私人航空在全球所起的作用却没有得到很好的量化。在此,我们利用 ADS-B Exchange 平台提供的 2019 年至 2023 年期间的飞行跟踪器数据,计算了该行业的二氧化碳排放量。2019-2023 年间 25,993 架私人飞机和 18,655,789 次单个航班的飞行时间与 72 种飞机型号及其平均燃料消耗量相关联。我们发现,2023 年私人航空的直接排放量至少为 1560 万吨二氧化碳,即每次飞行约排放 3.6 吨二氧化碳。近一半的航班(47.4%)航程短于 500 公里。私人航空主要集中在美国,68.7% 的飞机在美国注册。飞行模式分析证实了大量的休闲旅行以及文化和政治活动。2019-2023 年间,排放量增加了 46%,行业预期将继续强劲增长。需要制定法规来应对该行业日益增长的气候影响。根据对航班跟踪数据的分析,2019 年至 2023 年期间,私人航空的二氧化碳排放量增加了 46%,其中近一半航班的飞行距离不足 500 公里。
