Environmental accounting
In order to facilitate the aggregation of environmental accounting for the entire KITZ Group and ensure accuracy, the KITZ Group established an environmental accounting system within the environment, health, and safety information system, which is being operated by the Group.
Concept of environmental accounting
The KITZ Group introduced environmental accounting in order to achieve sustainable development, maintain a good relationship with society, and effectively and efficiently promote environmental conservation efforts. The KITZ Group Environmental Accounting System Manual was compiled in 2005. The Manual is designed to standardize the understanding of the accounting and to compare the environmental accounting information of all Group companies.

Referenced guidelines
The Ministry of the Environment, Environmental Accounting Guidebook (2005 Edition)
Calculation standards for environmental conservation costs
(1) Depreciation method: Calculated using straight-line depreciation for five years and included in the expenditures.
(2) Personnel expenses: Includes expenses related to equipment maintenance, environmental safety management, and environmental education.
(3) Research and development expenses: Includes expenses related to environmental development themes as defined in the Guidelines for Evaluation of Environmental Impact Reduction Associated with Technology Development.
Calculation standards of environmental conservation effects
Calculated as below.
Environmental impact of the current financial year less the previous year’s
Calculation standards of economic effects
(1) Profit: the actual value
(2) Saved cost
– The amount of energy and cost saved by waste reduction are calculated as follows.
Financial gain = {(previous financial year’s environmental impact / previous financial year’s basic unit standard) x current financial year’s basic unit standard – current financial year’s environmental impact} x previous financial year’s unit price
– Reductions in costs associated with recycling are calculated based on the actual intra-group transactions.
