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.
Coverage: Sharp Corporation production sites and production bases 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 the Rational Use of Energy (Energy Conservation Act) and the Japanese Ministry of the Environment’s Greenhouse Gas Emission Calculation and Reporting Manual
PFCs purchased HFCs, PFCs, sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3) purchased annually
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 in the 8 major categories* 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 8 major categories* 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).
  • Flat-panel TV, air conditioners, refrigerators, washing machines, air purifiers, microwave ovens, copiers/MFPs, solar cells
