Sixty companies out of Osaka Gas and its 150 consolidated subsidiaries, excluding companies housed in office buildings as tenants and overseas companies whose environmental performance data are difficult to grasp and whose environmental impact is minimal. One overseas subsidiary has been added to the list of companies subject to energy consumption and greenhouse gas (GHG) calculations. The number of total companies subject to the calculations varies from year to year due to company mergers and other factors. For FY2021 and beyond, results of offices of the core energy business companies are included in "Osaka Gas."

t-CO2/t*With an emphasis on properly evaluating the effects of reducing purchased electricity, the Daigas Group uses the average coefficient for thermal power sources to calculate CO2emissions for control purposes.
City gas: published values by Osaka Gas / Other fuels: Ministerial Ordinance Partially Revising the Enforcement Order of the Act on Promotion of Global Warming Countermeasures
- *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 Scope 3 emissions
-
Figures in parentheses are not subject to third-party verification.
Scope 3 greenhouse gas emissions are 0 because the energy used by tenants is included in Scopes 1 and 2 for Category 8, and all the investments are for business and policy purposes, not for investment purposes, for Category 15. The Scope 3 greenhouse gas emissions for Category 10 are based on our own calculations.
- *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.
