Sammendrag
Aviation emissions contribute to climate change and local air pollution, with important contributions from non-CO2 emissions. These exhibit diverse impacts on atmospheric chemistry and radiative forcing (RF), varying with location, altitude, and time. Assessments of local mitigation strategies with global emission metrics may overlook this variability, but detailed studies of aviation emissions in areas smaller than continents are scarce. Integrating the AviTeam emission model and OsloCTM3, we quantify CO2, NOx, BC, OC, and SOx emissions, tropospheric concentration changes, RF, region-specific metrics, and assess alternative fuels for Norwegian domestic aviation. Mitigation potentials for a fuel switch to LH2 differ by up to 3,1X10kgCO2-equivalents (GWP20) when using region-specific compared to global metrics. These differences result from a lower, region-specific contribution of non-CO2 emissions, particularly related to NOx.This study underscores the importance of accounting for non-CO2 variability in regional assessments, whether through region-specific metrics or advanced atmospheric modelling techniques.

Combining Fleetwide AviTeam Aviation Emission Modeling with LCA Perspectives for an Alternative Fuel Impact Assessment
Klenner, Jan; Lund, Marianne Tronstad; Muri, Helene Østlie; Strømman, Anders Hammer (Peer reviewed; Journal article, 2024)Reducing aviation emissions is important as they contribute to air pollution and climate change. Several alternative aviation fuels that may reduce life cycle emissions have been proposed. Comparative life cycle assessments ... -
Public support for aviation emission policies in India and Norway: Cross-country comparison
Kallbekken, Steffen; Skjeflo, Sofie Waage (Peer reviewed; Journal article, 2024)We examine public support for four policy instruments to reduce aviation emissions in India and Norway, analysing the determinants of support and the effect of information provision. Support is significantly higher in ...
