· Environmental protection effects
| Classification of environmental protection effects | Environmental performance indicators | Unit | FY 2009 | FY 2010 | Difference |
|---|---|---|---|---|---|
| Environmental protection effects related to resources employed in business operations | · Electric power | 1,000,000 kWh | 127 | 171 | ▲44 |

| · Kerosene | kℓ | 798 | 1,014 | ▲216 | |
| · City gas | 1,000 m3 | 108 | 117 | ▲9 | |
| · Water | 1,000 m3 | 2,537 | 3,122 | ▲585 | |
| Environmental protection effects related to the impact of business operations on the environment and waste generated by these operations | · CO2 emissions | 1,000 t-CO2 | 241 | 219 | 22 |
| · NOX emissions*1 | t | 1,325 | 1,055 | 270 | |
| · SOX emissions*1 | t | 490 | 383 | 107 | |

| · Construction soil generated (and removed from construction sites) | 1,000 m3 | 1,118 | 2,084 | ▲966 | |
| Environmental protection effects related to goods and services produced by business operations*2 | · Projected annual reduction in CO2 emissions during the operation stage (effects of taking the environment into account) | t-CO2 | 8,827 | 14,060 | ― |
*1 Excluding emissions generated from electric power generation
*2 Compared to the 1990 level for buildings to which the Law Concerning the Rational Use of Energy applies; projected emissions are calculated using the CASBEE eco-sheet
(Unit: ¥1 million)· Economic effects produced by environmental protection measures
| Economic effects produced by environmental protection measures | Amount | ||
|---|---|---|---|
| Economic effects produced by environmental protection measures (Actual effects) |
Profit | · Recycling of waste generated by major business operations | 177 |
| Cost savings | · Savings in energy costs as a result of energy conservation | 60 | |
| · Savings in waste disposal costs as a result of resource conservation and recycling | 2,879 | ||
| Economic effects produced by environmental protection measures (Estimated effects) |
Reduction in environmental impact in monetary terms | 31 | |
Presumed effects:
Reductions in recycled waste, CFCs, halons, paper, and other resources are converted into equivalent reductions in CO2 emissions. The value of CO2 is calculated using an average Nikkei-JBIC Carbon Quotation Index of ¥1,431.3 per ton for FY 2010.
Changes in environmental management indicators
· Proportion of environmental R&D costs to total R&D costs
(Environmental R&D costs/total R&D costs) (%)
(FY)
· Environmental impact ratio *Only Taisei-derived impact
(Amount of direct final disposal/value of construction work) (kg/million yen)
(FY)
· Environmental efficiency
(Sales/total environmental impact (construction sites and offices)) (¥1 million/t-CO2)
(FY)
Data were collected and totaled in reference to the following guidelines:
“Environmental Accounting Guidelines 2005” (Ministry of the Environment)
“Environmental Accounting Guidelines for the Construction Industry 2002” (three trade organizations in the construction industry)
Scope of data collection
1. Taisei’s office buildings (head office, branches, business headquarters, and other organizations)
2. Construction projects implemented by Taisei (new construction, additional construction and remodeling, repair, and demolition) and joint-venture construction projects for which Taisei acted as representative (excluding overseas construction work)
3. CO2 data provided indicate the level of CO2 emissions for Taisei’s share of construction projects (excluding overseas construction work).
Target period
From April 1, 2010 to March 31, 2011
Data collection
Detailed data for construction sites were collected using Taisei’s proprietary E-DAM (environmental data management system).
Sampling
Some of the data, including CO2 data, were collected through sampling.
Personnel costs
Personnel costs include Taisei’s standard personnel costs as classified according to official positions (administrative costs) and personnel costs incurred by subsidiary enterprises (upstream and downstream costs).
