Pathways to net-zero emissions from aviation
Candelaria Bergero, Payne Institute Fellow Greer Gosnell, Dolf Gielen, Seungwoo Kang, Director Morgan Bazilian and Steven J. Davis write about how international climate goals imply reaching net-zero global carbon dioxide (CO2) emissions by roughly mid-century (and net-zero greenhouse gas emissions by the end of the century). Among the most difficult emissions to avoid will be those from aviation given the industry’s need for energy-dense liquid fuels that lack commercially competitive substitutes and the difficult-to-abate non-CO2 radiative forcing. Here we systematically assess pathways to net-zero emissions aviation. January 30, 2023.
