Environmental Contribution

The Uchimizu Project

In the Otemachi, Marunouchi, and Yurakucho areas of central Tokyo, the Uchimizu Project has been conducted each summer since 2008 to battle the urban heat island effect.

“Uchimizu” means “watering” or “sprinkling” and is an old Japanese custom traditionally done in gardens and streets.
Uchimizu prevents dust from rising and cools the warm ground.

For this project, we use rainwater and kitchen wastewater that has been filtered.
We are proud of our continual participation in this environment-friendly event.


CO2 Reduction / Light-Down Campaign

Japan’s Ministry of the Environment (MOE) conducts a “CO2 Reduction / Light-Down Campaign” on the day of the summer solstice and every July 7, which has been designated as “Cool Earth Day” by the MOE. Through this campaign, the MOE encourages less lighting to reduce electricity use.

The NYK head office participates in this campaign every year by reducing evening lighting at the company cafe.

Ceiling lights are turned off and natural outside light is utilized. After 5:00 p.m., reduced lighting is supplemented by candlelight. And electricity use (lighting and electrical outlets) on this day is reduced by 30%.


Participation in World Wide Fund for Nature Japan

Since 2005, NYK has been a corporate member of the World Wide Fund for Nature (WWF) Japan.

The WWF, which operates in over 100 nations, is one of the largest conservation organizations in the world. Its mission is to promote biodiversity and reduce the negative impact of human activities on nature and wildlife.

NYK will continue to support the WWF's effort to achieve harmony between humans and nature.

Cooperation with research organizations' marine environmental research

Based on its experience in operating a worldwide fleet of ships, NYK supports the efforts of international research organizations and also conducts joint research by providing vessels as an environmental research field.

  • Research on marine pollution from toxic chemicals (cooperation in research with the National Institute for Environmental Studies)
  • Research on the movement of sea life, which happens when organisms stick to the surface of hulls or are trapped in the ballast water that ships take on in one location and discharge in another, and on the consequent ecological impact (cooperation in research with Kobe University)

In October 2007, NYK and two subsidiaries, Japan Marine Science Inc. and NYK Cruises Co. Ltd., received letters of thanks from the National Institute for Environmental Studies for their support of research.

NYK's Participation Helps Tohoku University Researchers Confirm CO2 Concentration Differences between Hemispheres

NYK is participating in a Tohoku University research project to study global greenhouse gas distribution and circulation. Over a period of 30 years, sample air is being taken at sea on a containership shuttling between Japan and Australia, and on another traveling between Japan and North America. Analyses of the sampled air have already revealed that the northern and southern hemispheres have varying concentrations of CO2, and also that concentrations fluctuate seasonally and yearly. By adding observation points on the ocean to points on land, we have contributed to research in this area.

University lectures

NYK arranges for experts from among its diverse staff to lecture at universities in Japan and thereby supports the education of students who plan to become seafarers or enter other segments of the shipping industry.

  • “Shipping Business Theory” at Tokyo University of Marine Science and Technology since 2000
  • “Social Aspects in the Shipping Industry” at Kobe University since 2006

Wind-Power Station in Yokohama

In April 2007, NYK became one of the Y-Green Partner companies that sponsor the large wind-power station operated by Yokohama City. The City in turn gives each company a Green Power*1 Certificate in proportion to the amount of the company's sponsorship. The certificates allow the companies to use equivalent amounts of “wind-generated” energy. The total amount for NYK from 2007 to 2016 was about 1130 MWh, which equals the yearly electricity consumption of about 324 average households.

*1 Green power
Electric power that is generated by means of renewable energy such as from biomass, wind, and solar technologies, which do not contribute to any increase of CO2 in the atmosphere

Planting Trees

NYK Group staff have participated in numerous tree-planting programs in cooperation with local communities.

In Thailand, we began the tree-planting Carbon Neutral Project in June 2007 and this project is scheduled to continue for more than 20 years.

NYK Line (Thailand) Co. Ltd.,
NYK RORO (Thailand) Co. Ltd.,
Yusen Logistics (Thailand) Co. Ltd.,
Nippon Cargo Airline (Thailand) Co. Ltd.
Double Wing Spirit Service Co Ltd
ANJI NYK Logistics Co., Ltd.

In addition, we have invested in a joint tree-planting project that started in 2003 in Albany, Australia, and in a Brazilian afforesting project that began in 2008 with wood-chip maker Amapa Florestal e Celulose S.A. (AMCEL).
