A swift turnaround? Abating shipping greenhouse gas emissions via port call optimization

Waiting times for trucks, trains, airplanes and ships in service represent apparent transport system inefficiencies, and measures to reduce these may have the potential to abate transport greenhouse gases (GHG) emissions. In international shipping, transportation researchers have pointed out that reduced waiting time in association with port calls holds such promise. The authors explore the potential for GHG abatement through port call optimization, focusing on crews and their employers - the shipping companies. Adding new empirical evidence to the transportation literature, the authors confirm the existence of idle time during port calls, and go beyond this in describing the causes for it. The authors show how several port stakeholders, including government officials, limit the crews’ and shipping companies’ room for maneuver in relation to port calls. The authors also show why the process of reducing waiting time in shipping is more complex than that for onshore transport modes, where real-time traffic information guides drivers’ route choices, and reduces congestion and waiting time. The authors' findings have implications for both policy makers and transportation research.
