Private aviation is making a growing contribution to climate change

S. Gössling, A. Humpe, et al.

This research, conducted by Stefan Gössling, Andreas Humpe, and Jorge Cardoso Leitão, highlights the alarming rise of CO₂ emissions from private aviation, which surged by 46% from 2019 to 2023, contributing at least 15.6 Mt CO₂ in direct emissions this year. The authors stress the need for regulatory measures to mitigate the sector's growing climate impact, especially as private flights predominantly cater to leisure in the USA.

Abstract
This paper investigates the growing contribution of private aviation to climate change. Using flight tracker data from 2019-2023, the authors calculate CO₂ emissions, finding that private aviation contributed at least 15.6 Mt CO₂ in direct emissions in 2023 (about 3.6 t CO₂ per flight). Emissions increased by 46% between 2019-2023. The study highlights the concentration of private aviation in the USA and its significant use for leisure purposes. Regulation is deemed necessary to address the sector's growing climate impact.
