Carbon Neutral Port Initiatives

Ports are logistics bases that handle more than 99% of Japan's imports and exports, and are industrial bases where various companies are located. The city of Yokohama, which has Yokohama Port, one of Japan's leading ports, is aiming to achieve carbon neutral ports (CNP) that reduces greenhouse gas emissions to zero by enhancing port functions that take into account decarbonization, such as promoting energy conversion of ships and coastal industries using next-generation energy (hydrogen, methanol, ammonia, synthetic methane, etc.) and accumulating coastal industries.
Since CO2 emitted from the coastal area of Yokohama City accounts for approximately 40% of the entire Yokohama city area, decarbonization of the coastal area will play a major role in achieving carbon neutrality in Yokohama City. To this end, we are working with the national government, private companies, and neighboring local governments to develop CNPs.

With the aim of achieving carbon neutrality in the coastal area of Yokohama City in 2050, Yokohama City is promoting the formation of a carbon-neutral port (CNP) that reduces greenhouse gas emissions to zero as a whole.
This time, based on the provisions of Article 50-2 of the Port and Harbor Law, the “Yokohama Port Decarbonization Promotion Plan (draft)” was created to promote the effective use of ports that contribute to the promotion of decarbonization through public-private partnerships. We raised opinions from 10:00 on Monday, December 23, 2024 to Tuesday, January 21, 2025.
