Environmental Performance Data

Disclosing GHG data based on the GHG Protocol

NYK regularly receives an assurance statement from a third-party certifier confirming that NYK is reporting and disclosing accurate numerical values for greenhouse gas (GHG) emissions by NYK Group companies. This data is then used in calculations to confirm that NYK is meeting the framework of Scope 1, 2, and 3 of the GHG Protocol*1, a benchmark that NYK has achieved since 2012. NYK's certification was the first time in the maritime industry that data collection, calculation, and reporting had been confirmed by a third-party to be in line with Scope 3.

Note 1: Electricity consumption in Japan is calculated on a market basis. CO2 emissions volume from electric power consumption for each fiscal year has been calculated using the coefficients for each electricity provider (actual figures for each fiscal year) published by Japan's Ministry of the Environment.

Note 2: For FY2021, we have partially reviewed the scope and revised the figures, certified after recalculation.

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.

Domestic

To better visualize our global environmental performance, we started collecting environmental performance data in January 2007 from major domestic consolidated group companies. As of March 2023, we collect 24 kinds of environmental performance data from 38 companies and 218 locations.

Overseas

In January 2008, we started collecting environmental performance data.
As of March 2023, 24 kinds of data, the same number being collected domestically, were being collected from 258 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.
