Carbon-Neutral Port Initiatives

Ports are logistics hubs handling more than 99 percent of Japan's imports and exports as well as industrial centers where various companies are located. The city of Yokohama contains the Port of Yokohama,one of Japan's leading ports,and is making efforts to transform it into a carbon-neutral port(CNP)with net zero greenhouse gas emissions. The measures to achieve this include upgrading port functions with consideration for decarbonization based on large-volume import, storage, and use of next-generation energy such as hydrogen and ammonia, and concentrating industry facilities in the waterfront district. The goal is to make the port carbon-neutral by 2050.
The waterfront district of Yokohama accounts for about 40 percent of its total carbon dioxide (CO2) emissions. Decarbonization of this district will therefore play a key role in achieving carbon neutrality for Yokohama as a whole. For this reason, the city is taking action to create a CNP through collaboration with MLIT (Ministry of Land, Infrastructure, Transport and Tourism), private companies, and neighboring municipal governments.

To achieve decarbonization of its waterfront district, Yokohama created the Yokohama Port CNP Council. The objective of this council is to hold conferences to have businesses in the waterfront district, people with relevant knowledge and experience, and administrative institutions promote decarbonization while sharing information and collaborating with each other.

The waterfront area of Yokohama plays a central role in the city's regional economy and has potential as a leader for decarbonization in Japan due to its diverse concentration of different companies. Therefore, the City is working toward the formation of a base for the import, production, and supply of next-generation energy sources such as hydrogen, ammonia, synthetic methane, and synthetic fuels that will contribute to decarbonization in the waterfront area of Yokohama. The Yokohama Decarbonization Innovation Council was established to enhance and lead decarbonization in Yokohama through the creation of decarbonization innovation through industry-academia-government partnerships, such as collaborations with local businesses that aim to pioneer the research, development, and utilization of next-generation energy and technology.
