Carbon-Neutral Port Initiatives

Last updated date:2024/7/12

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.

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.

Consideration of a financial framework utilizing sustainable finance, etc.

In April 2024, in the term of making Carbon-Neutral Port in the Port of Yokohama, the City of Yokohama concluded a MOU with Mizuho Bank for the purpose of collaborate consideration to create new financial support scheme to the activities for decarbonization of companies and groups at waterfront areas in the city of Yokohama.( Press release on April 23rd, 2024(PDF:403KB))

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.

July 2022 - Signed a collaboration agreement to expand the use of hydrogen and other next-generation energy sources in the Kawasaki and Yokohama waterfront area

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.

In May 2022, the City of Yokohama concluded a MoU with NYK Line(外部サイト), etc. for Acceptance of Ammonia-Fueled Tugboat (Press release on May 23rd, 2022)

Incentive programs for environmentally friendly vessels

To promote the use of low-carbon and decarbonized fuels and strengthen international competitiveness, we offer an incentive program to encourage environmentally friendly vessels to promote port calls. (More details)

Initiatives to utilize zero-emission vessels

Utilizing the Maritime Emissions Portal

Yokohama City is the only port in Japan to use the Maritime Emissions Portal, developed by RIGHTSHIP Pty. Ltd., a maritime platform specializing in ESG, to make a carbon neutral port. Through the Maritime Emissions 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))

Exploring the Utilization of Battery Tankers

In April 2024, the City of Yokohama concluded a MOU with TEPCO Power Grid, Inc. and Ocean Power Grid, Inc. to consider the future conception of grid network and the construction of new supply base of green power, which are necessary for forming Carbon-Neutral Port in the Port of Yokohama.

Efforts to form the Green Shipping Corridor

Green Shipping Corridor (GSC) is a newly proposed concept for decarbonizing shipping and port management that is gaining popularity worldwide. GSC is an initiative to promote the reduction of greenhouse gas emissions from shipping and port activities by introducing new technologies into the shipping routes connecting ports, and through public-private partnerships and policies.
The City of Yokohama is working toward the formation of the GSC with following ports.
Port of Los Angeles, Port of Oakland, Port of Long Beach, Ports of Republic of Singapore, Port of Hueneme
