Environmental data

・The aggregation range is equivalent to 95.3% of the entire Group (percentage figures refer to our environmental management activities)
・Verification by a third party has been completed for the results of the fiscal year 2023. The verification for the results of the fiscal year 2024 is scheduled to be completed by the end of October 2025.

Amounts of Energy Purchased

Transition of Amount of Energy Purchased

Notes

1.

Amount of grid connected power purchased (after amortization): The amount of renewable energy certificates amortized is deducted from the amount of grid connected power purchased.

2.

The scope of data collection includes all domestic and overseas bases.

3.

No heat was purchased.
Volumes of fuel purchased are aggregated based on lower heating value (J) and converted at a rate of 3,600 GJ, or 3.6 TJ, to 1 GWh.

4.

“Total” includes the amount of purchased electricity generated from renewable sources but excludes the amount of electricity generated in-house (both non-renewable and renewable energy)..

Breakdown of Amount of Fuel Purchased

*

As the calorific value per area of gas varies by supplier and pressure varies by supply pipe, amounts are converted at a rate of 1,000 m3 at a pressure of 0℃1 to 45 GJ.

Breakdown of Scope 1 and Scope 2 Emissions

Notes

  1. 1.

    The scope of data collection includes all domestic and overseas bases.

  2. 2.

    Our Scope 2 emissions have been calculated using the market-based method since fiscal 2023.

    • Emission coefficients in Japan: We use the adjusted emission factors (residual mix) of electricity suppliers from the Emission Factors by Electricity Utility Providers published by the Ministry of the Environment and the Ministry of Economy, Trade and Industry of Japan.

    • Overseas electricity emission factors: We use the latest country-specific average electricity emission factors from IEA Emission Factors 2024. For fiscal 2024, we are using the 2022 values.

Breakdown of Scope 1 Emissions

(kt-CO2e)

*ʼsemiconductor etching materialsʼ include use in semiconductor etching processes as well as in chamber cleaning processes in semiconductor manufacturing equipment.

Notes

1.

The scope of data collection includes all domestic and overseas bases.

2.

Greenhouse effect coefficient (GWP): Used AR5, the 100-year coefficient in the 5th IPPCC periodic report since fiscal 2021 in accordance with the COP24 international agreement. Used AR4 for fiscal 2013 to 2020.

3.

The calculation of emissions other than CO2 uses the IPCC inventory & (default) emission factors (IPCC2006 Tier2c factors) in accordance with the calculation guidelines of the Act on Promotion of Global Warming Countermeasures.
In addition, emissions due to SF6 use (proprietary inventory) in high-voltage manufacturing processes have also been added.
The default values (90%, 95% for NF3 only) are used for the exclusion rate of exhaust gas elimination systems for the etching process of semiconductors.
However, in each inventory for product HFC refrigerant filling processes and SF6 insulating gas filling processes, actual measured values are used instead of default emission coefficients.

4.

Since fiscal 2017, we have been undergoing third-party verification within the year following the year under review with respect to calculation methods, data sources, calculation processes, and companywide totals.

GHG Emissions by Business segment in Fiscal 2024

(kt-CO2e)

GHG Emissions by Country in Fiscal 2024

(kt-CO2e)

Scope 2 emissions is calculated using the market-based method
In Japan: We use the adjusted emission factors (residual mix) for each electricity supplier, as published by the Ministry of the Environment and the Ministry of Economy, Trade and Industry of Japan.
Overseas: We use the latest country-specific average electricity emission factors from "IEA Emission Factors 2024."

Scope3 Emissions (FY2024 results and Scope and Method Calculations)

(kt-CO2e)

Prepared based on the "Basic Guidelines on Accounting for Greenhouse Gas Emissions Throughout the Supply Chain Ver.2.7" by the Ministry of the Environment of Japan.

Notes

  • Final products (products that customers use directly as supplied by our company):
    Industrial electric furnaces, Store distribution equipment, Thermal power generation

  • Intermediate products (our products/components that are incorporated into customers' products and then provided to end users):
    Power semiconductors, Low-voltage inverters, Motors, Transformers, Turbines/generators

Transition of Scope 3 Emissions

Greenhouse Gas Emissions in Fuji Electric's Overall Supply Chain

(kt-CO2e)

Scope of calculation: Scope 3 Category 11 in fiscal 2024 is approximately 74% of emissions during the use phase of all our products.

Emissions Transaction System

Renewable Energy Use

(MWh)

Notes

Since fiscal 2022, we have been purchasing renewable energy and amortizing electricity certificates in Japan and abroad.

*1

Renewable power: On-site photovoltaic power generation (PPA), off-site renewable energy power generation, and green electricity

*2

Power consumption: Total amount of all power purchased + amount of photovoltaic (self-generated) power.

*3

Energy consumption: Total amount of all power purchased + amount of photovoltaic (self-generated) power + amount of fuel consumed.

Total Waste / Waste Sent to Landfills

(t)

Notes

1.

Total waste is the amount of unnecessary articles created during production activities (industrial waste, general waste, and valuable waste).

2.

Ratio of waste sent to landfills is calculated as follows: Waste sent to landfills ÷ Total waste

3.

In fiscal 2021, landfill waste increased due to difficulties in recycling fluorine sludge into cement overseas.

4.

The scope of data collection includes all domestic and overseas bases.

Hazardous waste / non-hazardous waste

(t)

Notice

Hazardous waste: Hazardous waste: Under Japanʼs Waste Management and Public Cleansing Act, businesses are responsible for all of the industrial waste they generate (including the issuing of manifests and final disposal). This law does not distinguish between hazardous waste and non-hazardous waste. We consider hazardous waste to be harmful waste materials and we therefore retallied our figures according to the following types of waste: waste oil, waste acid and waste alkali, organic and inorganic sludge, and used activated carbon.

Water Resources

Water Intake

(TCM)

Notes

1.

“Potable water” refers to drinkable tap water. “Industrial water” refers to water for industrial purposes that is not drinkable.

2.

Total water intake in Japan is the sum of potable water purchased, industrial water purchased, and groundwater intake.

3.

Volume of groundwater does not include groundwater used for soil cleanup, for agricultural purposes, or for melting snow.

4.

The scope of data collection includes all domestic and overseas bases.

Water Recycled

(TCM)

Notes

Recycling rate is calculated as follows: Amount of water recycled ÷ Amount used (Intake amount + Amount recycled)

Wastewater

(TCM)

Notes

Sewerage includes the drainage sent to general sewage treatment facilities in industrial parks.
Rivers and waterways include direct discharge to sea areas, drainage that has seeped underground, and evaporation at factories. However, it does not include the amount of drainage from rainwater at factories.
