Environmental Accounting

Mitsui Chemicals invests as much as is necessary in responsible care, including environmental initiatives and occupational health and safety. We also compile and publish our environmental accounts in accordance with the Environmental Accounting Guidelines set out by the Japanese Ministry of the Environment in 2005.

In fiscal 2016, we invested approximately ¥0.9 billion on protecting the environment.
In addition, expenses totaled around ¥22.0 billion on the back of higher research and development as well as other costs.
Including conserved resources and saved energy, the economic impact of our environmental activities this year was equivalent to approximately ¥1.4 billion. Moving forward, will continue to actively focus on environmental protection activities.
