The Port of Yokohama, in conjunction with the Port of Kawasaki, is currently conducting studies to achieve the status of carbon-neutral port. To provide a baseline for these studies, we mapped vessels and oil tank groups in the Port of Yokohama and the Port of Kawasaki on high-resolution optical images taken by the Pleiades-1B satellite on September 24, 2021, in order to then estimate the total greenhouse gas emissions from all the vessels in the port, as well as to examine potential areas for a conversion to hydrogen facilities in the future. The mapping showed 322 maneuvering vessels and 2682 moored vessels. More than 90 % of the moored vessels were located in the Port of Yokohama. Additionally, there were 68 and 78 oil tank groups in the Port of Yokohama and Port of Kawasaki, respectively. The City of Yokohama manages the Port of Yokohama as its port administrator and has a general understanding of information on vessels and oil tank groups. However, we do not have information on the exact number of vessels in the entire port, nor do we have accurate information on the oil tank groups, which are mostly on private property. Furthermore, little information is available on the adjacent Port of Kawasaki, whose administrator is the City of Kawasaki. The use of high-resolution optical satellite images provided detailed information that could not be obtained previously. This study approach was useful in studying the potential use of hydrogen, fuel ammonia, carbon-neutral gas, etc. as part of the effort to achieve carbon-neutral port status in the Ports of Yokohama and Kawasaki.
