Environmental Compliance

K J 

Kaneka Group continues working to reduce environmental risks through various means, including ISO 14001 internal audits and CSR safety and quality inspections, to check compliance with environmental regulations and legislation such as the Air Pollution Control Act and the Water Pollution Control Act, and with criteria in agreements with local governments.

Environmental Efficiency

K J 

We assess the environmental impacts of our production activities using Environmental Impact Points (EIP), which are compiled using the JEPIX methodology (see note 1), and we use those points to assess our environmental efficiency (see note 2).
Our total environmental impact in fiscal 2016 decreased slightly, by 0.4% from the previous year, to 4.58 billion EIPs, while our environmental efficiency dropped by 5.1% from the previous year due to a decline in sales.


1. The Japan Environmental Policy Priorities Index (JEPIX) methodology involves the calculation of an "eco-factor" coefficient for each emitted substance that has an environmental impact, using a ratio of the annual target for emissions under national environmental policies versus actual annual emissions ("Distance to Target"). The eco-factors are then multiplied by a quantity for each environmental impact to produce a single integrated index known as Environmental Impact Points (EIP). Calculations of eco-factors are done by the JEPIX Project (, in Japanese).

2. Environmental efficiency is a yardstick to measure efforts to maximize value while minimizing environmental impacts, with the aim of achieving sustainable growth. Kaneka calculates this by dividing net sales (yen) by the EIP.

■ Environmental Efficiency

■ Details of Total Environmental Impact

Check & Act

The environmental impact of greenhouse gas, hazardous air pollutants, and nitrogen discharge to coastal waters declined compared to the previous fiscal year, while the environmental impact of NOx and COD discharge to coastal waters increased, resulting in a slight decrease in the total environmental impact.
We will continue working to reduce environmental impact and improve environmental efficiency by promoting energy-saving activities.
