Fleet renewal or supply growth?

Enviado por agodoy el

We examine the impact of new aircraft (A320neo, B737 MAX) on total CO2 emissions, seeking to determine whether their greater fuel efficiency may be offset by supply growth. We draw on granular global data at the aircraft–airline–route level between 2017 and 2023 and employ propensity score matching and entropy balancing to build a sample of comparable airline–route pairs operated or otherwise by new aircraft. We then analyze how the share of new aircraft correlates with supply and carbon emissions by estimating a high-dimensional fixed effects model.
