Environment Activities at the NYK Head Office

At the beginning of each fiscal year since 2008, we have established specific action plans and targets to reduce CO2 emissions.

Use of LED lights

NYK has installed LED fluorescent lights at company-related facilities. LED lights not only use less electricity but also can be used for longer durations. Furthermore, LED lights that will not affect operation are turned off.


Water-saving devices

Water-saving devices have been attached to faucets in the lavatories.

Optimal use of window shades and air conditioning

We have placed emphasis on making optimal use of window shades and air conditioning.

In summer, a closed window shade during daylight hours can keep heat out and cool air in a building. In winter, closed blinds when the sun is down can keep cold air out and warm air in a building.


Open blinds on a clear winter's day allows warm sunshine to enter.


Closed blinds on a hot summer afternoon reduces the load placed on air conditioners.

Closed blinds on a hot summer afternoon reduce the load placed on air conditioners. It is extremely difficult to maintain comfortable office temperatures, so we coordinate with building management to efficiently maintain a comfortable office environment.


Temperature controls for each floor


Using temperature data from continually monitored floors, we seek to maintain a comfortable, energy-efficient office environment.

We are also making other efforts that will reduce environmental loads, such as turning some office lights off during lunch and other times.

Rooftop Garden

As part of the renovation of the Yusen Building, a rooftop garden was built to reduce the heat absorbed by the building in summer, thus trimming the energy needed to cool the building and the emissions generated as a result. The area has been named the “Green Deck” and includes a lawn, a section where herbs are grown, and even some outdoor fitness equipment. Moreover, the deck provides staff members a sanctuary where they may enjoy lunch outdoors, do a little exercise, and relax among the shrubbery.


Building Brownout Activities ⁄⁄ Yusen Real Estate Corporation ⁄⁄

In fiscal 2011, Yusen Real Estate Corporation implemented its “Win-Win Brownout” campaign, in which the company requested its tenants to share information and cooperate with building brownouts to drastically reduce energy consumption. As a result, energy use was reduced by an average of about 30 percent per month. In the end, this electricity savings in communal areas allowed Yusen Real Estate Corporation to reduce its tenants' electricity bills.

In fiscal 2012, Yusen Real Estate Corporation introduced an additional brownout activity called “We're on the same boat.” In this activity, rising electricity expenses were not passed on to tenants. Instead, by lowering the supplied capacity of electric power to a respective building, the basic charge for contracted power could be reduced, and rising prices were then absorbed through the tenants' cooperation with the brownout. In the end, this activity allowed electricity cost to be controlled.

In recognition of these activities, Yusen Real Estate Corporation received the Japan Association for Real Estate Sciences' fiscal 2013 Achievement Award.*1

This award is given to recognize the establishment of insightful new business programs or exceptional accomplishments that may have resulted in new real estate business. The award also recognizes achievements in “software” — i.e., finance, circulation, management, research, and publication — in addition to “hardware” — i.e., ideas for development.

Installation of solar-power generation equipment in training facility

Rooftop solar-power generation facilities at the NYK Tobitakyu general training institute have been working since 2002.
Consisting of six generators with 420 solar panels (120 centimeters by 80 centimeters) with a generating capacity of 50 kilowatts, equivalent to the power demand of approximately 15 households, the system can meet approximately30% of the electricity needs of the institute. Unused daytime capacity is sold to an electricity company.

Installation of LED Lighting at Yusen Logistics

As an energy conservation measure, Yusen Logistics Co. Ltd. had been looking to install LED lighting at their warehouses and offices. From 2011 to 2012, replacement of the conventional mercury lamp to LED lighting was carried out at the Narita Logistics Center warehouse. In September 2015, the lighting was switched to LEDs at the Chubu Logistics Center as well, resulting in an electricity consumption reduction of approximately 60%. And in May 2017, a trial to replace mercury lamps with LED lighting was carried out at the Toyooka Logistics Center. In addition, fluorescent lights at the Chubu Distribution Center were replaced with LED lighting. This was Yusen Logistics' first attempt at using LED lighting in the office area. Yusen Logistics is planning to conduct a full scale replacement of all office lighting to LED lamps in the future in order to further promote energy conservation and reduce the company's environmental burden.

Making Use of Advancements to Reduce CO2 Emissions at Domestic Terminals

At domestic terminals, we have implemented a number of environment-friendly measures.

(1) Installation of Hybrid-cargo-handling equipment*2
(Tokyo Container Terminal, Kobe Container Terminal)

NYK is in the process of introducing hybrid-cargo-handling equipment at two ports in Japan, a first at both these locations. At Tokyo's Ohi container terminal, the new equipment is 90 percent complete. And at the port of Kobe's Rokko Terminal, the replacement is 70 percent complete.

*2 Hybrid-cargo-handling equipment
CO2 emissions can be reduced by 40% by utilizing energy produced and stored when rolling down the crane.

(2) Installing Solar Cells at Tokyo Container Terminal

Together with group company NYK Trading Corporation, NYK has installed CIS solar cells*3 at the NYK container terminal in the Port of Tokyo's Ohi Terminal. Approximately 1,600 of these solar panels have been installed on the terminal gate rooftop. The annual generating capacity is about 165,500 kWh, about 10 percent of the electric power consumed annually at the administration building.

The environmental value of the electricity generated by this facility is to be shifted to a third party utilizing the green power certification system.

*3 CIS solar cells
Copper, Indium, Selenium, or CIS, are the major components of CIS solar cells, which have been drawing attention as next-generation solar cells because they do not contain silicon, which is in short supply due to excessive demand. The CIS solar cell belongs to the class with the highest photoelectric conversion efficiency among thin-film-type solar cells. In particular, due to the excellent absorption of sunlight with a black element, the CIS solar cell is superior to the crystalline silicon solar cell that has a bluish element, which reflects a blue light.

(3) New Revolutionary Container Hanger Featuring Solar Cells

NYK, JFE Engineering Corporation, and the Tokyo Port Terminal Corporation have built an innovative, state-of-the-art container hanger at the Ohi Container Terminal's No.6 berth.

This new hanger began operations in April 2011 and improves yard usage through efficient operations. And solar panels on the roof make the terminal much more environment friendly.


The terminal also features the following advancements:

  • Fuel additives*4 are used to improve fuel efficiency and reduce soot and, thus reducing air pollution.
  • Older trucks have been replaced with ones that emit less pollution.
  • Eco-driving training has been provided to truck drivers.
  • • Inner packages are used for malt transportation, and waste generated in container yards is recycled.
*4 Fuel additive
Factory trials indicate that fuel additives reduce particulate matter by about 25percent and CO2 by about 2percent.

Making Use of Advancements to Reduce CO2 Emissions in Los Angeles

Yusen Terminals Inc. (YTI) in Los Angeles has an on-site solar project that generates about 11,800 kWh of electricity a year from only 96 panels installed in collaboration with NYK parent company NYK Trading; company employees also use electric cars to get around the terminals. Both of these measures have led to a reduction of CO2 emissions and thus aided the City of Los Angeles's antipollution measures. The company also makes use of a power factor correction to efficiently deliver power. In addition, YTI has installed shoreside connection boxes at the terminals to allow moored vessels to plug in to shoreside electrical power as opposed to running on diesel power while at berth.
