Impact of fuel prices on energy efficiency of maritime ships

Abstract

Over the last decade, several policies have been implemented by the International Maritime Organisation (IMO) and the European Commission (EC) to affect the environmental performance of maritime shipping. Many of these policies result in higher fuel costs for shipping, either direct (e.g. in case of EU ETS) or indirect (e.g. in case of FuelEU Maritime1). In this study, we have investigated whether and to what extent increases in fuel prices influence shipping companies to invest in energy efficiency technologies or to improve their operational energy efficiency. For that purpose, we have econometrically studied the impact of historic variations in fuel prices on both technical and operational energy efficiency of maritime ships in the global fleet.
