Resource and Energy Conservation and Reduction of Greenhouse Gas Emissions print

In fiscal 2010, although production increased, energy use in terms of the equivalent consumption of crude oil rose only slightly due to energy savings initiatives at the Mizushima industrial complex and progress in companywide improvements. The energy consumption rate index (against 1990 levels)* has improved to 67.8.
The Energy Conservation Project at the Mizushima industrial complex is intended to conserve energy by reusing petroleum residue (or pitch) that is generated when extracting light oil distillates from heavy oil distillates (such as asphalt) as fuel for boilers, while reducing the use of heavy oil that had previously been used for fuel.

Reduction of Greenhouse Gas Emissions (CO2 Reduction)

Amount of CO2 Emitted

To achieve our ambitious goal of reducing CO2 emissions derived from fuel to 80% of 1990 levels by fiscal 2020, as specified by the Energy Conservation Law, we are taking aggressive steps to slash CO2 emissions. We have put into place an overall framework for reducing CO2 emissions by adding the impact of CO2 reduction to assessment items in ZΣ Activities for fiscal 2010. (ZΣ Activities: See more details of cost-control activities.)
CO2 emissions for fiscal 2010 were approximately 580,000 tons per year and 91% of 1990 levels. Looking ahead, we intend to further reduce this percentage by an average of 1% annually.
Due to amendments to the Energy Conservation Law, CSR Reports after fiscal 2009 have been changed from a business site basis to a business entity basis, and therefore the entity covered for calculation is limited to the ZEON CORPORATION; Okayama Butadiene Co., Ltd., an affiliated company, was excluded from calculation. Consequently, the consumption amount in fiscal 1990 was also revised.
