Abstract

Due to the ongoing increase in the number of commercial flights, greenhouse gas emissions from aviation are expected to rise significantly. Balancing the pursuit of productivity growth with environmental-footprint control policies comprises a long-term regulatory challenge. In this light, the main goals of the present paper are: (i) to measure the CO2 emissions of European airlines from 2000 to 2010, (ii) to compute airlines' productivity in developing an environmental-sensitive productivity index, (iii) to compare the obtained results with those resulting from a traditional index, and (iv) to identify the drivers affecting productivity changes. Our results show that on average, airlines' relative CO2 emissions have decreased. Although the airlines we studied experienced an average productivity increase-both considering and not considering negative externalities production-environ mentally sensible productivity growth is lower than traditional productivity growth. Finally, we find that improvements in load factor as well as a combined increase in stage length and aircraft size affect productivity changes positively, while fuel efficiency is significant only in the case of a CO2-sensitive measure of productivity.
