Environmental Data

Environmental Performance Data Scope 3: Calculation results
As part of earth-conscious activities, We are promoting resource saving (reduction of energy and water etc.) and reduction of carbon dioxide and waste. Although the total amount has increased due to the increase in sales (production volume) in recent years, the specific consumption has been improved due to the efficiency of facilities and work processes and resource saving activities.
As well as legitimate business activities, we incorporate environmental management systems (ISO14001) to continuously improve environmental performance.
Input Data
 Total Energy Input
 Water input
・  The data covers Japan sites and overseas affiliates.
・  Fossil fuels consists of LPG, city gas, LNG, gasoline, diesel, Kerosene.
・  Specific consumption is the total energy consumption divided by consolidated sales.
・  The data covers Japan sites and overseas affiliates.
・  Recycled water is the water regenerated by wastewater treatment equipment.
・  Specific consumption is the amount of supply water divided by consolidated sales.
Output Data
 Total Waste Generation
 Greenhouse Gas Emissions
・  The data covers Japan sites.
・  Recycled waste is the waste that is recycled and does not include landfilled waste.
・  Specific consumption is the total amount of waste divided by consolidated sales.
・  The data covers Japan sites and overseas affiliates.
・  The greenhouse gas emissions are described in terms of CO2 equivalent.
・  Others are greenhouse gases of non-energy origin such as CFC, HCFC, SF6.
・  Fossil fuels consist of LPG, city gas, LNG, gasoline, diesel, Kerosene.
・  Specific consumption is the total greenhouse gas emissions divided by consolidated sales.
