“K” LINE Group is taking the initiative for building a highly energy efficient logistics infrastructure while we recognize that our business activities impose environmental impact on the global environment and continue to evaluate it,  setting various targets in order to continuously reduce them.

Environmental load data regarding fuel consumption and electricity consumption in domestic and foreign consolidated subsidiaries are gathered and aggregated by Eco Track, our environmental data aggregation system, with this data being used to understand environmental impact produced by business activities of the entire “K” LINE group. In that regard, we are dedicated to seeing that the environmental performance data are visually available to the public so as to implement additional measures as needed, after such annual environmental data is verified and certified by a third party. We welcome and will utilize any comments or reviews offered by stakeholders regarding additional measures needed in order to reinforce our determination to continuously improve “K” LINE Group’s business activities.

Third-Party Verification of Greenhouse Gas (GHG) Emissions Data

The “K” LINE Group calculates its greenhouse gas (GHG) emissions in line with the Greenhouse Gas Protocol (GHG Protocol), an international standard for calculating and reporting greenhouse gas (GHG) emissions, and receives third-party verification and a Verification Statement for data on emission of GHG generated in the course of every business activity of the company   ranging from the top on down.

DNV GL Group, a third-party institution applies ISO 14064 (international standards related to GHG calculation, reporting and verification) to verify “K” LINE’s data on GHG emissions and evaluates its validity, thus affirming the reliability of the data disclosed and improving transparency. “K” LINE has built a system for quantifying GHG emissions, and every year applies the above standards to accurately calculate, understand and evaluate its emissions, thus aiming to continuously reduce them.

Environmental Accounting

In accordance with the Ministry of the Environment's Environmental Accounting Guidelines 2005, we have aggregated the figures for the target period, January to December 2016. The figures below are from the companies that comprise the Environmental Management System (EMS) of the “K” LINE Group. The amount of investment is the total cost for purchasing equipment used for carrying out the measures in each item. The amount of expenses is the total cost for maintaining the equipment, treating waste, maintaining the EMS and other measures. The amount of expenses excludes depreciation and amortization costs (792.6 million yen).

Note: Figures in the tables below are rounded up or down to the nearest million. Accordingly, the sum of the values may differ from the total amount.
