Of Osaka Gas’s 154 consolidated subsidiaries, 56 are subject to the calculation. The others are companies whose environmental effects are minimal and whose environmental data are difficult to grasp. They are housed in Osaka Gas office buildings as tenants or are foreign companies not subject to such calculation. One overseas subsidiary was added that is subject to energy use and GHG calculations. However, the aggregate number of companies may differ by fiscal year due to company mergers, etc.

t-CO2/t* CO2 emissions of purchased electricity subject to control are calculated using the average factor of thermal power plants so that the Daigas Group can precisely assess how the reduction of purchased electricity has contributed to a reduction in CO2 emissions. Emission factor used for calculation of emissions in FY2017: 0.65 t-CO2 / 1,000 kWh stipulated in the Plan for Global Warming Countermeasures adopted at the Cabinet meeting in May 2016.
Emission factor for gas is the value published by Osaka Gas.
Emission factor for other fuels: Ministerial Order for Promotion of Measures to Cope with Global Warming
- *2 CO2 emission factor for purchased electricity when calculating greenhouse gas emissions for comparison
-
CO2 emissions are calculated using the actual value of the emission factor of the electric power company in the previous fiscal year. The emissions are calculated by multiplying the usage volume for each electric power company by the emission coefficient for that company, in accordance with the agreements signed with multiple electric power companies.
Therefore, the year-to-year difference in CO2 emissions does not necessarily reflect the effect of emission control measures.
The effective emission factor is used as the emission factor to ascertain actual emissions due to electricity use. (reference: The adjusted emission factor, which reflects the Kyoto Protocol's credit scheme, is used in the Greenhouse Gas Emissions Calculation and Reporting System.)
- *3 Figures in parentheses
-
The figures are not subject to third-party verification.
The figures are 0 in Category 8 because energy consumption arising from tenant occupancy is included in Scopes 1 and 2. The figures are 0 in Category 15 because all the investments are for sales and policy reasons, not for investment purposes.
- *4 Calculation of methane emission
-
Methane emission is calculated using GHG coefficient 25.
(Reference: IPCC Guidelines for National Greenhouse Gas Inventories 2012)
- *5 Chlorofluorocarbons
-
Emissions of gases subject to the Act on Rational Use and Proper Management of Fluorocarbons are calculated.

Figures in the table do not appear to add up to the totals due to rounding.
- *1 Estimated amount of soil generated
-
The amount that is believed to be generated when doing pipe installation without using current methods for reducing the amount of excavated soil. The difference between this figure and the actual amount generated is the reduced amount.
- *2 Amount utilized
-
The amount used outside of Daigas Group, such as for improving farmland soil. Final disposal is the amount generated minus the amount recycled and the amount utilized.
