Analysis of fuel efficiency of largest European airlines in the context of climate change mitigation

Abstract

In recent years Greenhouse Gas (GHG) emissions released by aircraft engine and their contribution to climate change gained major importance among airlines operating across European Union member countries after the inclusion of the aviation sector in the European Union Emissions Trading Scheme (EU ETS). According to EU ETS, all intra-community flights became subject to GHG emission restrictions since the year 2012 with allocated annual carbon dioxide emission allowances that airlines will have to comply with. This research presents estimations of fuel consumption and carbon dioxide emissions among flight operations of aircraft used by largest European airlines in chosen flight routes of high daily passenger demand. Results show that some alternatives remain available for European airlines and some opportunities may emerge to reduce costs and increase revenues through enhanced engagement with air passengers towards a more environmentally friendly behaviour.
