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 fiscal 2016, the amount of GHG emitted by the entire group increased by 5,000 tons-CO2e compared with fiscal 2015. Specifically, the sites inside Japan increased their emissions to 197,000 tons-CO2e from 195,000 tons-CO2e in fiscal 2015 and the sites outside Japan, to 296,000 tons-CO2e from 293,000 tons-CO2e in fiscal 2015 (see G1).
The amount of energy used by the entire group increased by 2,000 kL compared with fiscal 2015. Specifically, the sites inside Japan increased their usage to 88,000 kL from 87,000 kL in fiscal 2015 and the sites outside Japan, to 126,000 kL from 125,000 kL in fiscal 2015 (see G2).
Energy usage is broken down into 92% for SCOPE 2 and 8% for SCOPE 1 (see G3).
Improvement in energy intensity, which we aim to achieve in the medium term, was 17.3% in fiscal 2016 (see G4).
We will continue to review production processes with a focus on core products to further improve the production efficiency for lower energy usage.

  • Changes in the conversion factor have a major impact on greenhouse gas calculations, so the medium environmental targets were set according to energy consumption (crude oil equivalent), a factor that has measure able results.
  • 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 295 kilotons-CO2e (group), 7,136 tons-CO2e (domestic sites) from commutes, 532 tons-CO2e from business trips (domestic sites), 4,627 tons-CO2e from disposal and processing of waste (domestic sites) and 30,200 tons-CO2e from transporting products (group).
