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.
Initiatives being considered at the Port of Yokohama
CNP Formation Initiatives
Yokohama Decarbonization Innovation Council
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.

Yokohama Port CNP Council
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.

Approaches to wide-area coordination for effective use of next-generation energy
Collaboration with the City of Kawasaki
In July 2022, Yokohama and Kawasaki concluded an agreement on collaboration for expanded use of hydrogen and other types of next-generation energy in their waterfront districts.
Yokohama and Kawasaki are next to each other. One of Japan’s largest industrial complexes is in Kawasaki. The two cities concluded the agreement in order to become more effective in achieving carbon neutrality and constructing supply chains.

Collaboration with Ibaraki Prefecture
In December 2022, Ibaraki and Yokohama concluded an agreement to collaborate on decarbonization and industrial revitalization.
Ibaraki and Yokohama signed a collaborative agreement to strengthen the shipping network to improve convenience for cargo owners and promote the attraction and acceptance of cruise ships.

Initiatives for the establishment of a hydrogen supply chain
In November 2021, the City of Yokohama and ENEOS Corporation concluded an agreement to collaborate on the establishment of a hydrogen supply chain.
Through this agreement, the city will aim for the Port of Yokohama to became a carbon-neutral port and work on decarbonization in the waterfront district. The City of Yokohama and ENEOS will strive to achieve a “hydrogen society” by developing and implementing a hydrogen supply infrastructure using pipelines.

Implementation of a NEDO study
Yokohama is implementing an investigative study on the use of hydrogen for CNP formation. This study was adopted by the program for studies of hydrogen manufacturing and use potential commissioned by the New Energy and Industrial Technology Development Organization (NEDO).

Initiatives to encourage the widespread use of next-generation ship fuel
Yokohama is making efforts to encourage the widespread use of liquefied natural gas (LNG), which is the sole next-generation ship fuel currently available for practical use. As part of our measures to become a strategic international container port, we are preparing functions for supply of LNG-fueled ships, the number of which is steadily increasing, and establishing the Port of Yokohama as a supply hub.
Initiatives to utilize zero-emission vessels
Utilizing the Maritime Emission Portal
Yokohama City is the only port in Japan to use the Maritime Emission Portal, developed by RIGHTSHIP Pty. Ltd., a maritime platform specializing in ESG, to make a carbon neutral port. Through the Maritime Emission Portal, we will strive for more accurate volume of emissions from vessels, and to make a carbon neutral port by promoting DX.

Onshore Power Supply for Ships
In July 2023, five companies and two associations established the "Promotion Council for Zero Emission Chargers for Ships", which aims to promote the widespread use of standardized shore-to-ship power stations. The City of Yokohama participates in the council as an observer. (Learn more（PDF：764KB）)
