Environmental Accounting

As a tool for environmental management

With a view to promoting environmental management, Toshiba Group is working to introduce an environmental accounting approach aimed at collecting accurate data on investments and costs required for its environmental conservation initiatives and analyzing the collected data in order to reflect investment effects and cost benefits in managerial decision making.

Environmental costs are calculated in accordance with the Ministry of the Environment's Environmental Accounting Guidelines 2005. As for environmental benefits, Toshiba Group's environmental accounting assumes four basic concepts: competitive advantages, prevention of potential environmental risks, internal benefits, and external benefits. We classify benefits into four categories based on combinations of these concepts to develop a comprehensive approach to environmental accounting: customer benefits due to reduced power consumption of products, actual economic benefits resulting from reductions in the amount of waste and energy consumed, assumed economic benefits estimated to result from reductions in air pollutant emissions, and benefits resulting from preventing potential risks. To assess benefits, we show reductions in environmental impact in physical amounts and also calculate benefits on a monetary basis.

Environmental costs and benefits

Total environmental costs increased by 3.3% from the previous year to 52.7 billion yen. Of the different business sections, the electronic device section, which handles semiconductors, accounted for the largest percentage of total environmental costs, followed by the Energy & Infrastructure Group and the Community Solutions Group. Total investments increased by 24% from the previous year to 11.5 billion yen.

The total amount of environmental benefits was 82.8 billion yen. The breakdown of the total is as follows: actual economic benefits were 9.2 billion yen; assumed economic benefits were 44.2 billion yen; customer benefits were 29.4 billion yen; and risk prevention benefits were 7 million yen. The most important cause of the increase in assumed economic benefits was the reduced environmental impact of Sigma Power Ariake Co., Ltd., which engages in the thermal power generation business. The amount of assumed economic benefits excluding the effects of the power generation business was −0.5 billion yen. Considering the large effect of the power generation business on environmental benefits, we also show the changes in environmental benefits after excluding the effects of Sigma Power Ariake.

We will continue to appropriately analyze environmental costs and develop environmental management measures to further increase environmental benefits.

Cost benefits of environmental management measures

The figure shows the changes in the cost benefits of measures for climate change mitigation and waste disposal over the past three years. We compared the costs incurred in taking measures to mitigate climate change and dispose of waste against the total amount of reductions in payments related to energy consumption and waste disposal compared to the previous year as well as sales of valuables during the current year. In the table below, costs are expressed as business area costs and benefits as actual benefits.

In FY2015, measures to mitigate climate change and to dispose of waste both brought larger benefits than the costs of implementing them.

The major issue to be addressed going forward is how to overcome two conflicting problems: an increase in emissions of environmental pollutants as a result of business expansion and the need for cost reductions. Toshiba Group will also analyze the cost benefits and other financial aspects of environmental management measures in more detail.

Environmental costs (FY2015)

Unit: million yen
Category Description Investment Costs
Total 11,544 52,652
Business area costs Reduction in environmental impact 9,840 21,947
Upstream/downstream costs Green procurement, recycling, etc. 614 964
Administration costs Environmental education, EMS maintenance,
tree planting on factory grounds, etc.
179 3,259
R&D costs Development of environmentally conscious products, etc. 900 26,267
Public relations costs Support for local environmental activities, donations, etc. 10 43
Environmental damage restoration costs Restoration of polluted soil, etc. 0 172

Environmental benefits (FY2015)

Category Description Reductions in environmental impact Benefits measured as a monetary value (million yen) Calculation method
Total monetary benefits 82,814  
(A) Actual benefits Costs that can be measured directly as a monetary value, such as electricity and water charges Energy -1,589,355(GJ) 2,712 Reductions in electricity charges and waste processing costs compared to the previous year, plus sales of valuables
Waste 4,313(t) 6,584
Water −27(m³) −120
Total monetary benefits 9,177
(B) Assumed benefits Reductions in environmental impacts measured as a monetary value Reduction in the amount of chemicals discharged 424 (t) 44,248 To obtain monetary values, we assessed the impact of different substances by using the equivalent amount of cadmium for each substance, which we calculated based on environmental standards and on threshold limit values for chemical substances specified by the American Conference of Governmental Industrial Hygienists (ACGIH-TLV), and then multiplying such amounts by the damage compensation for cadmium contamination. In order to compare different environmental impacts by the same standard, reductions in environmental impacts on the atmosphere, hydrosphere, and soil compared to the previous year are shown alongside monetary amounts that represent the values of such reductions.
(C) Customer benefits Reductions in environmental impacts during product use measured as a monetary value Reductions of CO2 emissions during use 2.39 (million t-CO2) 29,382 Reductions in environmental impact throughout product life cycles measured in physical and monetary units (monetary amounts). The product life cycle includes (1) material procurement, (2) manufacture, (3) transport, (4) use, (5) collection and transport, (6) recycling, and (7) proper treatment. In this report, we focused on reductions in environmental impacts during product use. We used the following equation to calculate energy-saving benefits: Benefits (yen) = Σ [(Old model annual power consumption – New model annual power consumption) × Number of units sold annually × Standard unit electricity price]
(D) Risk prevention benefits Reductions in environmental risks before investment 7 Benefits from investments in environmental structures, such as dikes designed to prevent soil and groundwater contamination, evaluated for their effects of hedging against possible future risks. We used the following equation to calculate risk avoidance effects per capital investment project: Standard purification and repair costs and the occurrence factor were calculated using values originally estimated by Toshiba to evaluate risks involved in chemical leaks.
Risk avoidance effects = Amount of chemicals, etc. stored or retained × Standard purification/ repair costs × Occurrence factor

Reductions in environmental impact for actual and assumed benefits indicate differences between FY2014 and FY2015.
Reductions in environmental impact for customer benefits are based on comparisons between the benchmark year (in principle FY2000) and FY2015.
Negative benefits indicate that the increase in environmental impacts exceeded reductions due to increases in production and other factors.
