Overview of Environmental Impact

Material Balance

Sharp gathers data to gain an overview of the burden its 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. Sharp then uses these values to reduce its environmental burden.

Material Balance in Business Activities (Fiscal 2018)

  • *1 TJ (terajoule) = 1012 Joules
  • *2 Amount of solar power generated; amount of green power certificates purchased.
  • *3 Total weight of product shipments and waste, etc. (estimate).
  • *4 Amount recycled through closed-loop plastic material recycling technology.
  • *5 In Japan.
  • *6 Annual energy used and amount of CO2 emitted by products in the 13 major categories sold in the reporting year (estimate).
  • *7 Total weight of products in the 8 major categories sold in the reporting year and packaging materials used (estimate).

Boundary of Environmental Performance Data, Calculation Standards for Environmental Performance Indicators

The environmental performance data are calculated based on the following period, coverage, and calculation standards.

< Period Covered, Coverage >
Period covered: Fiscal 2018 (April 2018 to March 2019)
Coverage: Sharp Corporation production sites and production bases in Japan and overseas

Calculation Standards for Environmental Performance Indicators

Environmental Performance Indicators Calculation Method
Input Product manufacture Energy consumed Calculated based on the Act on the Rational Use of Energy (Energy Conservation Act) and the Japanese Ministry of the Environment's Greenhouse Gas Emission Calculation and Reporting Manual
Water resources consumed Consumption and recycled use of industrial-use water, tapwater, and groundwater
PFCs purchased HFCs, PFCs, sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3) purchased annually
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 in the 13 major categories*1 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 in the 13 major categories*1 sold in the reporting year. Calculation based on each product's annual energy consumption rate (using a heat input per unit of 9.97 MJ/kWh).
Recycle Disposal, recycling Home appliances(4 kinds)*2 Amount of used home appliances (4 kinds) recycled
Copiers/MFPs Amount of recycled copiers and MFPs
PCs Amount of recycled PCs
Closed-loop plastic material recycling Amount of recycled plastic used, which was produced through closed-loop material recycling
  • *1 LCD TVs, air conditioners, refrigerators, washing machines, air purifiers, microwave ovens, LED lights, Blu-ray Disc recorders, facsimiles, mobile phones, LCD monitors, copiers/MFPs, solar cells
  • *2 TVs (CRT TVs, flat-panel TVs), air conditioners, refrigerators/freezers, washing machines/dryers
Environmental Performance Indicators Calculation Method
Output 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 GHG Protocol Calculation Tools (GHG emissions from purchased electricity)
  • 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 4th 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 and transferred (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
Product shipments Total weight of products in the 13 major categories* sold in the reporting year, plus packaging material used (estimate)
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 in the 13 major categories* sold in the reporting year, based on their energy consumption (estimate)
Disposal, recycling Disposal after recycling [Weight of 4 kinds of home appliances, PCs, and copiers/MFPs collected] – [Weight recycled into new products or materials, or reused]
  • LCD TVs, air conditioners, refrigerators, washing machines, air purifiers, microwave ovens, LED lights, Blu-ray Disc recorders, facsimiles, mobile phones, LCD monitors, copiers/MFPs, solar cells
