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 energy use and reducing energy consumption.

Results of efforts to reduce greenhouse gases and energy consumption

In FY2013, the Group's overall greenhouse gas emissions decreased year-on-year by 18 kilotons-CO2e. This figure includes a decrease from 206 kilotons-CO2e to 184 kilotons-CO2e at domestic sites and an increase from 271 kilotons-CO2e to 275 kilotons-CO2e at overseas sites compared with FY2012 (See G1). Energy consumption for the Group overall decreased by 6 thousand kiloliters from FY2012. This figure includes a decrease from 91 thousand kiloliters to 81 thousand kiloliters at domestic sites and an increase from 113 thousand kiloliters to 117 thousand kiloliters at overseas sites compared with FY2012 (See G2). The breakdown for 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 32.7% in an average of FY2011-13 (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 medium-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 factor of electricity in regards to domestic greenhouse gas emissions in FY2012. In FY2013, the FY2012 CO2 conversion factor 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 among stakeholders. In line with this request, we have been trying to keep up with SCOPE 3.
We have ascertained that our greenhouse gas emissions from commutes was 6,443t-CO2e (domestic sites), 527t-CO2e from business trips (domestic sites), 3,769t-CO2e from disposal and processing of waste (domestic sites) and 24,100t-CO2e from transporting products (group).
