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 FY2015, the Group’s overall greenhouse gas emissions increased year-on-year by 3 kilotons-CO2e. This figure includes a decrease from 200 kilotons-CO2e to 195 kilotons-CO2e at domestic sites and an increase from 285 kilotons-CO2e to 293 kilotons-CO2e at overseas sites compared with FY2014 (see G1).
Energy consumption for the Group overall increased by 2,000 kiloliters from FY2014. This figure includes a decrease from 89,000 kiloliters to 87,000 kiloliters at domestic sites and an increase from 121,000 kiloliters to 125,000 kiloliters at overseas sites compared with FY2014 (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 39.8% for FY2011-15 (see G4).
We will continue to work on reviewing 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).

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

We have ascertained that our greenhouse gas emissions from purchased goods/services were 293 kilotons-CO2e (group), 6,934 tons-CO2e (domestic sites) from commutes, 514 tons-CO2e from business trips (domestic sites), 4,263 tons-CO2e from disposal and processing of waste (domestic sites) and 27,058 tons-CO2e from transporting products (group).
