Environmental Management
Environmental Accounting
Scope and Period of Data Compilation and Method of Disclosure
Period: April 1, 2006 March 31, 2007
Scope of Data Compilation: Mitsubishi Electric Corporation and 101 of its domestic and overseas affiliates and subsidiaries (79 domestic, 22 overseas)
The scope of data compilation has been expanded to include all companies that have established an environmental plan (the same scope as this Environmental Report) in order to more accurately ascertain environmental management for the group as a whole.
Scope until fiscal 2006: 50 companies subject to environmental accounting (29 domestic, 21 overseas)
Scope in fiscal 2007: 101 companies that have established an environmental plan (79 domestic, 22 overseas)
Note: The number of companies with an environmental plan increased from 85 companies in fiscal 2006 (62 domestic, 23 overseas).
- Data is disclosed in accordance with the environmental accounting guidelines issued by Japan's Ministry of the Environment.
- The benefits of environmental protection are ascertained in terms of real benefits, which consist of earnings and savings, and estimated benefits. Estimated benefits include the economic benefits to customers of using our products, such as lower electricity bills, and environmental improvements produced outside our business sites.
Fiscal 2007 Overview
Environmental costs and benefits increased substantially over the previous fiscal year due to expanding the scope of data compilation.
We proactively invested in high-efficiency equipment and energy efficiency support devices at a targeted rate of 0.1% of net sales, in order to help prevent global warming. We also reinforced defensive measures by investing in pollution prevention initiatives, such as wastewater treatment facilities and measures to prevent air pollution.
In the areas of parts and materials procurement and environmental measures for products, we invested in production lines for both energy efficient consumer products and industrial products. Concentrated investment, primarily in replacing production lines, in order to comply with the RoHS Directive ended in fiscal 2006, so the overall amount of investment decreased.
As a result, capital investment increased ¥2.18 billion over the previous year to ¥6.04 billion on a group basis, and rose 1.04 billion to ¥3.47 billion for Mitsubishi Electric Corporation.
Environmental protection expenditure increased 900 million over the previous year to 13.88 billion on a group basis. It decreased 430 million to 9.94 billion for Mitsubishi Electric Corporation. The change was largely due to expanding the scope of data compilation.
The overall amount of physical benefits increased substantially due to expanded production. Per unit of net sales, benefits were equivalent to the previous year. The increase in emissions of chemical substances increased due to higher production volume and an increase in the number of managed substances.
Earnings and savings both increased substantially.
Customers benefited in terms of lower electricity bills and environmental benefits were produced with use of our refrigerators, air conditioners, total heat exchange ventilators (Lossnay), energy efficient lamps, energy efficient electrical discharge machines, elevators with inverters, photovoltaic power systems and other products.
