Marginal climate and air quality costs of aviation emissions
Aviation emissions have been found to cause 5% of global anthropogenic radiative forcing and ~16 000 premature deaths annually due to impaired air quality.
When aiming to reduce these impacts, decision makers often face trade-offs between different emission species or impacts in different times and locations. To inform rational decision-making, this study computes aviation's marginal climate and air quality impacts per tonne of species emitted and accounts for the altitude, location, and chemical composition of emissions.
