Overview of Environmental Impact

Material Balance

We gather data to gain an overview of the burden our business activities place on the environment. Measured items include the consumption of energy and materials in business activities, the emissions of greenhouse gases, and the generation of waste. We then use these values to reduce our environmental burden.

Coverage: Sharp Corporation production sites and production subsidiaries in Japan and overseas

Calculation Standards for Environmental Performance Data

The environmental performance data are calculated based on the following calculation standards.

Input

Environmental Performance Indicators Calculation Method
Procurement, R&D, product manufacture Energy consumed Calculated based on the Act on Rationalizing Energy Use and the Japanese Ministry of the Environment’s Greenhouse Gas Emission Calculation and Reporting Manual
Water resources consumed Consumption and recycled use of water purchased from third parties (industrial-use water, tap water) and groundwater
Chemical substances handled (PRTR-listed) Among the substances covered under the PRTR Law, the total amount of substances handled annually at each plant in quantities of 500 kg or more
Chemical substances handled (VOCs) Among the 20 types of volatile organic compounds (VOCs) specified by Japan’s four major electrical and electronic industry associations, the total amount of substances handled annually at each plant in quantities of 1 metric ton or more
Materials consumed Total weight of products sold in the reporting year (estimate), plus waste, etc. generated
Logistics Energy consumed Revised ton-km method
Product use Energy consumed Estimate of annual energy used by products sold in the reporting year. Calculation based on each product’s annual energy consumption rate.

Output

Environmental Performance Indicators Calculation Method
Procurement, R&D, product manufacture Greenhouse gas emissions
  • CO2 emissions from purchased electricity
    Japan:
    Using CO2 emission coefficient by electric power company (adjusted) published by Japan’s Ministry of the Environment and the Ministry of Economy, Trade and Industry
    Overseas:
    Using emission coefficients published in the environmental reports, etc. of electric power companies, or emission coefficients published in the IEA Emissions Factors
  • CO2 emissions from consumed fuel
    Using emission coefficient published in the Ministry of the Environment’s Greenhouse Gas Emission Calculation and Reporting Manual
  • Greenhouse gases other than CO2
    Using global warming potential published in the 5th Assessment Report by the Intergovernmental Panel on Climate Change (IPCC)
Drainage Annual drainage into public water areas and sewer system
Chemical substances released and transferred (PRTR-listed) Among the substances covered under the PRTR Law, the total amount of substances handled annually at one or more plant in quantities of 500 kg or more that were released and transferred
Chemical substances released (VOCs) Among the 20 types of volatile organic compounds (VOCs) specified by Japan’s four major electrical and electronic industry associations, the total amount of substances handled annually at each plant in quantities of 1 metric ton or more that were released and transferred
NOx emissions Annual emissions
SOx emissions Annual emissions
COD (chemical oxygen demand) Drainage into public water areas
Nitrogen pollutant load Drainage into public water areas
Phosphorous pollutant load Drainage into public water areas
Waste, etc. Industrial waste + general office waste + valuable resources recovered
Final landfill disposal Final landfill disposal of industrial waste + final landfill disposal of general office waste
Logistics CO2 emissions Revised ton-km method
Product use CO2 emissions Amount of CO2 emitted by products sold in the reporting year, based on their energy consumption (estimate)

Recycle

Environmental Performance Indicators Calculation Method
