■The values for the individual Chubu Electric Power companies are listed up to FY2019 and the total combined values for three companies consisting of Chubu Electric Power Co., Inc., Chubu Electric Power Grid Co., Inc. and Chubu Electric Power Miraiz Co., Inc. companies are listed from FY2020.（Chubu Electric Power Co., Inc. split off its power transmission and distribution businesses into Chubu Electric Power Grid Co., Inc. and its sales businesses into Chubu Electric Power Miraiz Co., Inc. on April 1 2020.)

※１ Reflects adjustments involved in CO2 emission credits, non-fossil fuel energy certificates and the FIT scheme for renewable energy obtained from the methods stipulated in the Act on Promotion of Global Warming

Countermeasures. Figures in parentheses represent Basic emissions factor and Basic emissions.

※２ Figures are rounded and may not match the total.

※３ GHG emissions quantification is subject to uncertainty when measuring activity data, determining emission factors, and considering scientific uncertainty inherent in the Global Warming Potentials.

※４ Scope of calculation is as follows:

FY2019: Chubu Electric Power Co., Inc. (before split offs)

FY2020: Chubu Electric Power Co., Inc., Chubu Electric Power Grid Co., Inc. and Chubu Electric Power Miraiz Co., Inc. FY2021:

Not in parentheses … Chubu Electric Power Co., Inc., Chubu Electric Power Grid Co., Inc. and Chubu Electric Power Miraiz Co., Inc.

In parentheses … Chubu Electric Power Co., Inc., Chubu Electric Power Grid Co., Inc., Chubu Electric Power Miraiz Co., Inc., + 7 of the domestic consolidated subsidiaries as of the beginning of FY2021 FY2022:

Not in parentheses … Chubu Electric Power Co., Inc., Chubu Electric Power Grid Co., Inc., Chubu Electric Power Miraiz Co., Inc. + 8 of the domestic consolidated subsidiaries as of the beginning of FY2022

In parentheses … Scopes 1 and 2: Chubu Electric Power Co., Inc., Chubu Electric Power Grid Co., Inc., Chubu Electric Power Miraiz Co., Inc. + 37 of the domestic consolidated subsidiaries as of the beginning of FY2022 Scope 3: Chubu Electric Power Co., Inc., Chubu Electric Power Grid Co., Inc., Chubu Electric Power Miraiz Co., Inc. + 11 of the domestic consolidated subsidiaries as of the beginning of FY2022

FY2023：

Not in parentheses … Chubu Electric Power Co., Inc., Chubu Electric Power Grid Co., Inc., Chubu Electric Power Miraiz Co., Inc.+ 15（＊）of the domestic consolidated subsidiaries as of the beginning of FY2023

＊Chubu Plant Service Co., Ltd., C-TECH CORPORATION, Techno Chubu Co., Ltd., C Energy Co., Inc., Chuden Real Estate Co., Inc., Chuden Auto Lease Co., Ltd., Chuden CTI Co., Ltd., ES-CON JAPAN Ltd.,

TOENEC CORPORATION, TOENEC Service Co., Ltd., Asahi Synchrotech Co., Ltd., Diamond Power Corporation, CEPO Handa Biomass Power Co.,Ltd., MIRAI Design Power Co., Inc., Chuden Transportation Service Co.,Ltd

In parentheses … Chubu Electric Power Co., Inc., Chubu Electric Power Grid Co., Inc., Chubu Electric Power Miraiz Co., Inc. + 36 of the domestic consolidated subsidiaries as of the beginning of FY2023

FY2024： Chubu Electric Power Co., Inc., Chubu Electric Power Grid Co., Inc., Chubu Electric Power Miraiz Co., Inc. + all of the domestic consolidated subsidiaries as of the beginning of FY2024

※5 Scope1：

Emissions of greenhouse gases released directly into the atmosphere from emission sources within organizational boundaries.

Calculated, in principle, with the emission factors specified in the GHG emissions accounting, reporting, and disclosure system administered by Japan's Ministry of the Environment, based on the Act on the Rational

Use of Energy and the Act on Promotion of Global Warming Countermeasures.

※6 Scope2：Emissions due to the electricity consumption.

※7 Offices, power plants, etc：Calculated by using the adjusted emissions factor for each electricity retail company.

※8 Transmission and distribution losses：

Calculated by subtracting the amount of electrical energy at use end from that at transmission end and multiplying the result by the emission factor of general electricity transmission and distribution utility companies in accordance with the GHG Protocol Corporate Accounting and Reporting Standard and GHG Protocol Scope.

※9 Scope3：

Indirect greenhouse gas emissions from business. We follow major guidelines have been published:

"the GHG emissions accounting, reporting, and disclosure system administered by Japan's Ministry of the Environment", based on "the Act on the Rational Use of Energy" and

" the Act on Promotion of Global Warming Countermeasures"

"Corporate Value Chain (Scope 3) Accounting and Reporting Standard(GHG protocol)"

"Green Value Chain Platform (Japanese Ministry of the Environment website, which provides Scope 3 emissions calculation methods and models)（Ver.3.5）" "IDEA Ver.2.3"

"Evaluation of Life Cycle CO2 Emissions of Domestic and Foreign Biomass Fuel for Coal-fired Power Plant" （CRIEPI Report Y10010 (May 2011))"

"Comprehensive Assessment of Life Cycle CO2 Emissions from Power Generation Technologies in Japan"（CRIEPI Report Y06 (July 2016))"

※10 Category１：Product/service price × emission factor

※11 Category２：Amount of a price increase of non-current assets × emission factor

※12 Category３：

The sum of the following three values;

-Emissions from generation of electricity we procured and sold to end users： the quantities of electricity procured from other companies × emission factor

-Emissions from upstream activities (extraction, production and transportation) of fuels for electricity we procured and sold to end users： the quantities of electricity procured from other companies × emission factor

-Emissions from upstream activities (extraction, production and transportation) of fuels we consumed： the quantities of fuels consumed × emission factor

※13 Category４：Calculated in accordance with the Specific Shipper Business Report under the Act on the Rational Use of Energy.

※14 Category５：Industrial waste, etc. generated × emission factor

※15 Category６：Business travel expenses × emission factor

※16 Category７：Travel expenses for employee commuting × emission factor

※17 Category11：LNG・Gas sales volume × emission factor etc.

※18 Category12：Expected waste volume × emission factor

※19 Category13：Number of leased assets, etc. × emission factor

※20 Power generation capacity owned by Chubu Electric Power Co., Inc. for business（the capacity of joint project is counted by equity share）.

※21 Losses include power consumption within the substation.
