PV Systems
In 2014, our company installed and began operating a photovoltaic system at the Minami-Honmoku MC-1 and 2 Container Terminals taking advantage of the feed-in tariff (FIT) scheme as the first such initiative at the Port of Yokohama. Since 2016, we have also been operating photovoltaic power generation systems within Minami-Honmoku MC-2 and Honmoku D-5 Container Terminals. Other than that, PV systems have been installed on the rooftops of facilities such as the Daikoku warehouse No. 4 owned by Yokohama City, and private warehouses.

| Capacity | 520kW | 310kW | 230kW |
| Operation start | March 2014 | March 2015 | March 2015 |
| Electricity output （annual average） | 574,000 kWh/ year | 424,000 kWh/ year | 266,000 kWh/ year |
| CO2 emissions reduction （annual average） | 249 t-CO2 | 184 t-CO2 | 115 t-CO2 |
Utilization of renewable energy in electricity procurement
We have supplied 100% electricity derived from renewable energy sources to every terminal served through our managed substation facilities since FY2022.
Our power is actually renewable energy power that utilizes renewable energy certificates issued by renewable energy power plants located in 13 municipalities in the Tohoku region, with which Yokohama City has concluded a partnership agreement in support of the “e.CYCLE” demonstration project to revitalize the Tohoku region through the use of electricity derived from renewable energy generation promoted by the City of Yokohama. In addition, a portion of the electricity bill is used by the partner municipalities as a fund for regional revitalization, thereby contributing to the revitalization of the region.
Switch to LED Lighting
In 2016, we began converting existing facilities to LEDs and have completed 100% conversion of yard lighting (outdoor) to LEDs, contributing to a 40% to 60% reduction in electricity consumption compared to conventional lighting.
We are also making progress in switching to LEDs for indoor lighting; every piece of lighting equipment installed in our managed facilities is scheduled to be switched over to LEDs by the end of 2024.
Reduction of CO2 emissions from our operations
We aim to be carbon neutral in terms of CO2 emitted from electricity and fuel consumption from our business activities (consumption by our offices, company-owned vehicles, etc.).
As for company-owned vehicles, we will gradually switch to hybrid vehicles and aim to introduce EVs in the future.
[Electricity]
The purchase of Renewable Energy Certificates (RECs) provides access to electricity with almost zero CO2 emissions. (from FY2023)
[Fuel (gasoline)]
We plan to implement carbon offsets by purchasing J-Credit corresponding to the amount of fuel used, aiming to achieve zero CO2 emissions in real terms. (From FY2023)
