Abstract

 Measures for achieving carbon-neutral ports have been progressing in Japan and decarbonization of international shipping has been discussing at IMO. Whereas, numerous of container ships have been waiting offshore of various world ports, the increase of CO2 emission by this waiting was concerned.

 This study estimated additional CO2 emission by offshore waiting ships at all container terminals in Tokyo Bay and the effect of countermeasures. As a result, it was revealed that the emission of offshore waiting corresponds to 15% of that of berthing ships and the three fourths of the emission possibly be decreased by the adjustment of entering time into Tokyo Bay and slow steaming in the bay.
