PCB (Poly Chlorinated Biphenyl) storage

We have no PCB-containing equipment in our business sites since March 2017.
In March 2017, we completed, through a nationally designated service provider,appropriately disposing of the three PCB-containing fluorescent light ballasts that hadbeen stored at our former Osaka Plant, and making them harmless.

Prevention of environmental pollution

We comply with the regulations of the local governments in which our plants and Research and Development Center are located in Japan.

Note

Reporting boundary

In principle, environmental data covers all facilities including sales offices in Japan, and Suzhou Plant in China as a major overseas production facility. For other operational sites, the scope of reporting is determined on an individual basis.

Guidelines referenced

These data have been prepared with reference to the Environmental Reporting Guidelines (2018 edition, Ministry of the Environment of Japan), the Basic Guidelines on Accounting for Greenhouse Gas Emissions Throughout the Supply Chain (Ministry of the Environment of Japan / Ministry of Economy, Trade and Industry of Japan, Ver. 2.5), the Environmental Accounting Guideline (2005 edition, the Ministry of the Environment of Japan), the GRI Standards, the Emissions intensity database for calculating greenhouse gas emissions of organizations through the supply chain (ver.3.4) and the Greenhouse Gas Protocol.

Numerical results

Total numbers may not always match, due to the effect of rounding and other reasons.
