Environmental Performance
Environmental Performance 2017
Since FY2004, Nidec has been making and promoting for implementation a three-year medium-term environmental conservation plan, and the fifth one was launched in FY2015. In the focus areas of “greenhouse gases (CO2),” “electricity,” “water,” and “waste disposal” in our business activity-based environmental burden reduction, we aim to reduce our three-year average by 3% on an intensity basis* from base year FY2015 levels.
*Intensity basis: Per employee for non-production sites, and per US$1,000 of sales for production sites.
This plan covers Nidec Group companies’ head offices, R&D sites, and production sites inside and outside Japan.
Past environmental performance
 |
 |
|
|
Mainly due to reduction in the total electricity usage, the total emissions decreased approximately 3%, and the intensity-based emissions decreased approximately 6%, from FY2016 levels. |
Power-saving-based and other effects resulted in an approximately 1% reduction in the total electricity usage, and a 5% decrease in intensity-based electricity consumption, from FY2016 levels.
|
|
 |
 |
|
|
The increase in the number of employees and other factors caused an approximately 13% increase in the total water usage, and an approximately 9% increase in intensity-based water usage, from FY2016 levels. |
Mainly due to the increase in the recycle ratio of metal and other types of trash, the total amount of final waste disposal decreased approximately 24%, and the intensity-based waste disposal decreased approximately 27%, from FY2016 levels. |
 |
 |
|
|
The greenhouse gas emissions increased mainly due to the increase in production equipment’s operation ratio and in the usage of fuels for cooling equipment, while intensity-based emissions decreased approximately 10% mainly due to increased sales, from FY2016 levels. |
The total electricity consumption increased approximately 4% due to, among other reasons, in-house component production-led production line expansion and introduction of automatic production equipment based on the growing product demands, while the intensity-based electricity consumption decreased approximately 10% due to higher sales and improved production efficiency per unit of product, from FY2016 levels.

|
|
Some of our factories’ water usage and leak reduction, and other water-saving measures resulted in an approximately 2% reduction of the total water usage, and an approximately 14% reduction of the intensity-based water usage, from FY2016 levels. |
The final waste disposal increased approximately 3% mainly due to production volume and factory workforce increase, as well as expansion of waste types to manage, while the intensity-based waste disposal decreased approximately 11%, from FY2016 levels. |
Number of business sites covered in the environmental conservation plan
The fifth medium-term environmental conservation plan covers companies that were part of the Nidec Group as of FY2015, the base year of the plan.
