Outline of Environmental Impacts

Overview of Environmental Impacts

Toshiba Group handles a wide range of products and services from household appliances and information/communications equipment to semiconductor and electronic components and power generation facilities. It will work to improve eco-efficiency by understanding and analyzing its environmental impacts.

The following material flow chart shows data on resource inputs such as the consumption of energy, water and chemical substances and data on outputs such as the environmental impact of emissions into the air and waters and the impact of generation of waste in FY2008. In addition, it shows data on the input of raw materials and the volume of major products shipped, as well as changes in such data during the past five years. These data were collected from 538 Toshiba Group companies (actual results for FY2008).

Input: [Materials*¹ 1,392 thousand t, Iron 631 (45%),Plastics 168 (12%), Others 593 (43%)] [Energy 57,082TJ*², Electricity 49,049TJ, City gas 3,442TJ, Bunker A heavy oil 562TJ, LPG 1,046TJ, Kerosene 67TJ, Light oil 1,093TJ, Others 1,823TJ] [Water 55,880 (thousand m³), Industrial water 34,260m³, City water 7,430m³, Groundwater 14,190m³] [Chemical substances Amount handled 62t] → Business Processes[R&D and Design → Procurement → Manufacturing] → Output: [Amount of major products shipped 541 thousand t] [Waste Total amount generated 292 thousand t, Amount recycled 251 thousand t, Amount for final disposal 17 thousand t] [Environmental impacts on air*³ Greenhouse gases 3,070 thousand t-CO₂, CO₂ 2,430 thousand t-CO₂, PFC 430 thousand t-CO₂, HFC 50 thousand t-CO₂, SF₆ 150 thousand t-CO₂, Others 10 thousand t-CO₂, SOX 748t, NOX 3,269t, Particles of soot 122t] [Environmental impacts on water Total volume of wastewater 47,740 thousand m³, (Amount of water reused 5,990 thousand m³), (Amount of water recycled 13,560 thousand m³), BOD 330t, COD 740t, Suspensoid(SS) 1,816t, Total nitrogen 256t] [Chemical substances Amount released 2.1 thousand t, Amount transferred 6.9 thousand t]

Input: [Weight of end-of-use products recovered (Weight of items processed) 100,284t, Disposal] → Recovery and Recycling → Output: [Weight recycled 79,257t, Four home-appliance products 63,529t PCs 1,123t, Medical equipment 4,708t, Others 9,898t] [Amount of waste after recycling 21,026t]

The data related to environmental impacts as verified by Bureau Veritas Japan Co., Ltd. (only review for overseas data) have been extracted from Environmental Report 2009.

*1: Material inputs according to resources, including composite materials, are calculated based on the Estimation Method for Material Inputs using Input-Output Table (EMIOT), a method developed by Toshiba. Detailed information on material inputs for each resource is available on the website.
*2: TJ=10¹²J, PJ=10¹⁵J. Joule is a unit of work done or energy expended as heat or as electricity.
1J=approx. 0.239 calorie
*3: For the power factor, 4.07t-CO₂/10-thousand kWh is used. The figures enclosed in parentheses are those calculated using the power factor, 2.97t-CO₂/10-thousand kWh, as average during the period from fiscal 2008 to fiscal 2012, which is set by the Federation of Electric Power Companies of Japan as a target for the voluntary action plan.
