Environmental Contribution

Support of Zero Emission Tokyo

In support of initiatives by the Tokyo Metropolitan Government's Bureau of Environment to make zero CO2 emissions in Tokyo, NYK has donated 14,027 tons of CO2 credits (excess reduction credits) acquired through energy conservation efforts in accordance with Tokyo's Cap-and-Trade Program (total emission reduction obligation and emission trading scheme). NYK aims to contribute to environmental preservation for maintaining a sustainable society.

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.

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.

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 40 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
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.

Wind-Power Station in Yokohama

Since April 2007, NYK had been one of the Y-Green Partner companies that sponsor the large wind-power station operated by Yokohama City for 10 years. 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 was about 1130 MWh, which equals the yearly electricity consumption of about 324 average households.

  1. *1Green 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
