Protecting the precious environment
We introduced environmental accounting in fiscal 2004 to get a grasp of environmental conservation activities in quantitative terms and promote such activities in an efficient manner.
Scope of calculations
Haseko Corporation's activities
- Completed works at 159 worksites (new building works: 131, demolition works: 28)
- Offices (Tokyo region: Shiba Head Office Building/Yokohama Branch, Kansai region: Osaka Hiranomachi Building, Nagoya Branch/Kyoto Branch)
April 1, 2018 to March 31, 2019
The following cost items were aggregated by using "Environmental Accounting Guidelines 2005 (Ministry of the Environment)" and "Environmental Accounting Guidelines in the Construction Industry 2002 (Japan Federation of Construction Contractors)" as reference.
- Business area costs
- Pollution prevention costs: Costs for measures to prevent air pollution, water contamination, noise, vibration, etc. were aggregated.
- Global environmental conservation costs: Costs for measures to prevent global warming, save energy, prevent the destruction of the ozone layer, etc. were aggregated.
- Resource circulation costs: Costs for waste separation/recycling and appropriate processing, etc. were aggregated.
- Upstream/downstream costs
Labor costs incurred in proposing environment-conscious designs were aggregated.
- Administration costs
Costs for environmental conservation management activities and ISO14001:2015 implementation and maintenance costs were aggregated.
- R&D costs
Costs for research and technological development related to environmental conservation were aggregated.
- Social activity costs
Costs for making donations, providing assistance, etc. to environmental groups and local communities were aggregated.
- Environmental remediation costs
Costs for repairing the surrounding environment and manifest purchasing expenses (fund portion) were aggregated.
