* Affiliated Companies

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.

The CO2 emission coefficient for the purchased electricity used is 0.69 kg-CO2/kWh for up until FY2017 and 0.65 kg-CO2/kWh for FY2018 and later.

*1 Environmental Management Efficiency: The results up to FY2017 are calculated values per gas sales volume using the LIME2 coefficient. The results after FY2018 are calculated values per gas production volume using the latest LIME coefficients.

*2 Figure shown in ( ): Figures in parentheses after FY2018 are calculated using the same formula as in FY2017.

*3 CO2 emissions per a certain volume of gas produced: Figures until FY2017 represent CO2 emissions per gas sales volume.

*4 Industrial waste / general waste (final disposal rate): Until FY2017, core companies had been subject to calculation of final disposal rates. Since FY2018, subsidiaries have been subject to calculation of final disposal rates. The number of companies subject to calculation may vary depending on the year due to corporate merger and the like.

Figures in the table do not appear to add up to the totals due to rounding.

*1 Calculation of CO2 emissions

The following emission coefficients are used to calculate CO2 emissions.

Purchased electricity	City gas	Gas before calorific value adjustment process	Gasoline	Diesel oil	LPG	LNG	Heavy fuel oil A	Kerosene	Coal
^*0.65 or 0.69 t-CO2/ 1,000 kWh	2.29 t-CO2/1,000 Nm³	2.23 t-CO2/1,000 Nm³	2.32 t-CO2/kl	2.58 t-CO2/kl	6.17 t-CO2/1,000 m³	2.7 t-CO2/t	2.71 t-CO2/kl	2.49 t-CO2/kl	2.33 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.
