Environmental Performance Data

Summery in fiscal year 2017

The environmental mass balance shows the balance of the used energy and resources and output of waste and exhaust gases of the whole business activity. NYK grasps the relation of our business activity and the environment to reflect the results to our environmental management plan and activities to reduce our environmental impact.

  • * The amount of greenhouse gas of our fleet is calculated based on “GUIDELINES FOR VOLUNTARY USE OF THE SHIP ENERGY EFFICIENCY OPERATIONAL INDICATOR” agreed in Maritime Environment Protection Committee of IMO (International Maritime Organization) in August, 2009.
  • * Moreover, the amount of the exhaust of greenhouse gas from the office and the terminal of a domestic running own business is calculated based on Coefficient from electric power company and “Law concerning promotion of measures for controlling global warming” of the Ministry of the Environment.

Obtaining Environmental Load Data from Domestic and Overseas Group Companies

Grasping the environmental burdens of energy consumption is a first step to reducing the burdens. We collect data on environmental burdens such as electricity usage, fuel consumption, industrial waste, and so on from domestic and overseas consolidated subsidiaries companies in an effort to comprehensively grasp the load situation throughout all our group companies and promote further reductions at the individual company level.
In fiscal 2017, we began using the Eco Track environmental load data collection/compilation system to obtain more efficient and accurate data.


To better visualize our global environmental performance, we started collecting environmental performance data in January 2007 from major domestic consolidated group companies. As of August 2018, we collect 18 kinds of environmental performance data from 47 companies and 244 locations.


In January 2008, we started collecting environmental performance data.
As of August 2018, 18 kinds of data, the same number being collected domestically, were being collected from 199 main overseas consolidated group workplaces. This network is not only a tool for collecting data but also a route for environmental communication. Moreover, we are continually working to improve the accuracy of all data.
