Curbing Global Warming

There are three categories for greenhouse gases emitted during the course of business activities:
Direct emissions from use of energy (SCOPE 1), indirect emissions from energy use (SCOPE 2) and indirect emissions other than from energy use (SCOPE 3). Greenhouse gas emissions cannot be easily measured, so we concentrate on managing energy use and reducing energy consumption.
We have also begun investigations into SCOPE 3.

Results of efforts to reduce greenhouse gases and energy consumption

In FY2012, the Group's overall greenhouse gas emissions increased year-on-year by 10 kilotons-CO2e. This figure includes a decrease from 195 kilotons-CO2e to 186 kilotons-CO2e at domestic sites and an increase from 252 kilotons-CO2e to 271 kilotons-CO2e at overseas sites. (See G1.)
Energy consumption for the Group overall increased by 4 thousand kiloliters from FY2011. This figure includes a decrease from 95 thousand kiloliters to 91 thousand kiloliters at domestic sites and an increase from 105 thousand kiloliters to 113 thousand kiloliters at overseas sites compared with FY2011. (See G2.) The breakdown of energy consumption was 93% in SCOPE 2 and 7% in SCOPE 1. (See G3.) The average energy consumption per unit of the environmental medium-term target improved by 33.0% in an average of FY2011 - FY2012. (See G4.)
We continue to work on reviewing the production processes, especially those for our major products, in order to further improve production efficiency and reduce total energy consumption.

Note: Changes in the conversion factor have a major impact on greenhouse gas calculations, so the middle-term environmental targets were set according to energy consumption (crude oil equivalent), a factor that has measureable results.

Note: Greenhouse gas emissions are calculated using GHG Protocol factors (electricity by country).

Note: There was a review and revision to the CO2 conversion coefficient of electricity in regards to domestic greenhouse gas emissions in FY2011. In FY2012, the FY2011 CO2 conversion coefficient was used.

Efforts on Indirect Emissions Other than from Energy Use (SCOPE 3)

In recent years, there has been an increasing trend to seek the disclosure of information on SCOPE 3 in addition to SCOPE 1 and SCOPE 2. First, in line with this request, we have ascertained our greenhouse gas emissions from the commutes and business trips of our employees at domestic sites. Greenhouse gas emissions from the commutes of our employees at domestic sites in FY2012 were 6,884t-CO2e, while this was 425t-CO2e for greenhouse gas emissions from business trips.
