Environmental Performance Data

Environmental Accounting

With a view to promote environmental management, we are engaging in “environmental accounting” to sum up and analyze our own environmental conservation investments and reflect return on investment in managerial decision-making.
As environmental conservation investments in FY2018, air-conditioner upgrades and introduction of LED lighting were mainly implemented.
In addition, research and development of inverters, electric drive systems for electric vehicles, solar and wind power generating systems, etc., were approximately 1.09 billion yen, and the amount of investment in global environmental conservation was approximately 1.46 billion yen.
In terms of environmental conservation, CO2 emissions were reduced by 2,843 tons (equivalent to 11% of the total emissions of the previous FY) through energy-saving, energy-creating investments and activities to improve energy-saving operations.
We also realized economic effects of approximately 107,030,000 yen in energy costs and approximately 104,930,000 yen in waste disposal due to the recycling of waste.

Effects of environmental conservation

Classification of effects of environmental conservation Environmental performance indicator [Unit] FY2017 FY2018
Effects of conservation regarding environmental load and waste materials from business activities Amount of CO2 emissions reduced in business places [t-CO2]*1 2,401 2,152
  • *1: For calculation of CO2 emissions from electric power, the emissions factors made public by electric power companies are used.

Waste disposal cost 10,493 11,397

* Environmental conservation costs, effects of environmental conservation, and economic effects of our six production plants in Japan are summed up based on the Ministry of the Environment’s “Environmental Accounting Guidelines 2005.”

List of Environmental Data

We are working toward self-action objectives on a daily basis in order to inspire commitment toward environmental load reduction. The environmental data (results) from FY2014 to FY2018 is listed below.

  • [Range of applicable data] Yaskawa Electric (including partners within business sites) and major domestic and overseas group companies (13 domestic companies and 8 overseas companies)

Third-party verification of greenhouse gases

To improve the reliability of the calculated greenhouse gas emissions (Scope 1, 2, and 3), we receive third-party verification by Japan Quality Assurance Organization.
