We study the factors affecting pollution, noise annoyance and global warming social costs produced by aviation, considering all the fleet currently operating. We analyze different aircraft-engine combinations, leading to a dataset of about 1,500 different observations, with relvant variability in terms of externalities produced. Our econometric analysis shows that aircraft age is a main determinant of environmental social costs: a 1-year younger aircraft leads to a -0.32% in social costs. We found a complementary relation among pollution, noise annoyance and global warming: the impact of age on them has the same sign. We also show that aircraft size has a positive impact on social costs: this implies that wide aircrafts generate higher costs than medium, small and light ones. On the contrary size has a negative impact on per-passenger social costs. Hence, policy makers, in designing incentives towards a environmentally sustainable aviation, have to decide first which is the main goal: either limiting the overall social costs (i.e., inducing airlines to choose smaller size aircrafts and higher frequency) or limiting per-passenger costs (i.e., providing incentives to adopt higher size aircrafts and lower frequency).

Abstract

We study the factors affecting pollution, noise annoyance and global warming social costs produced by aviation, considering all the fleet currently operating. We analyze different aircraft-engine combinations, leading to a dataset of about 1,500 different observations, with relvant variability in terms of externalities produced. Our econometric analysis shows that aircraft age is a main determinant of environmental social costs: a 1-year younger aircraft leads to a -0.32% in social costs. We found a complementary relation among pollution, noise annoyance and global warming: the impact of age on them has the same sign. We also show that aircraft size has a positive impact on social costs: this implies that wide aircrafts generate higher costs than medium, small and light ones. On the contrary size has a negative impact on per-passenger social costs. Hence, policy makers, in designing incentives towards a environmentally sustainable aviation, have to decide first which is the main goal: either limiting the overall social costs (i.e., inducing airlines to choose smaller size aircrafts and higher frequency) or limiting per-passenger costs (i.e., providing incentives to adopt higher size aircrafts and lower frequency).
