Environmental data

・The aggregation range is equivalent to 95.2% 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 2022. The verification for the results of the fiscal year 2023 is scheduled to be completed by the end of the fiscal year 2024.

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.

    Power coefficients are used to calculate the indirect CO2 emissions from power plants for each kWh of electricity purchased.
    Japan source – FY2023: Emission coefficients by electric utility (Announced by the Ministry of the Environment and the Ministry of Economy, Trade and Industry) FY2022: Japan's average power coefficient by the Electric Utility Low-Carbon Society Council (Fiscal Year 2022: 0.436 kg-CO2e/kWh)
    Overseas source - Average power coefficients for the respective countries described in IEA-Emission Factors (2022 edition) : Coefficients for [fiscal] 2021 are used for fiscal 2023.

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 (IPCC1996 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.

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

(km3)

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

(km3)

Notes

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

Wastewater

(km3)

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.
