Do Operating on the Basis of Green Procurement Guidelines

TAISEI has formulated Green Procurement Guidelines for the purpose of applying materials, equipment, and methods that have less environmental impact during the design, construction, and demolition of structures. Green procurement item categories are reviewed annually. TAISEI's green procurement rate for fiscal 2012 was 30.6%*.
One item (energy-saving electric toilet seats) was added to the 76 items in fiscal 2011, making 77 items. In fiscal 2012, 61 of these items were adopted in 65 construction design projects, and the number of items adopted per project came to 9.2 items.
Meanwhile, the construction divisions have designated priority items, including ready-mixed concrete using blast-furnace cement, blast-furnace cement, recycled aggregate, slag aggregate, recycled steel (recycled reinforcing bars and steel frame), liquefied stabilized soil, high-efficiency fluorescent light fixtures, and environmentally-friendly thermal insulation. TAISEI is promoting introduction of these items to our construction sites.

Plan Preservation of Biodiversity and Environmental Preservation Activities

Do Promote education for understanding of TAISEI involvement in biodiversity issues

Conducted two biodiversity e-learning sessions for all employees with a response rate of over 90%.

Do Promote environmental contribution activities

Conducted activities that included helping create local green areas (Tokyo Greenship Action), helping create nest boxes for dormice, and Shinjuku cleanup activities (Zero Garbage Day), among others. Assisted Animal-pathway & Wildlife Association (a company) that was established to disseminate the results of animal pathway research.
The TAISEI 1 Ton Club was launched in 2010 as an activity to purchase Kyoto carbon credits (CO₂ emissions credits) based on the goal of cutting CO₂ emissions. The Club was held again in 2012 based on the goal of carbon dioxide absorption, with employees giving donations to support preservation of the Kamaishi forest and tree planting activities in Borneo. A total of 747 employees donated to Kamaishi forest preservation activities and 675 to Borneo tree planting activities.

Plan Respond to Environmental Risks

Do Achieve zero environmental law violations by improving knowledge of related laws

Our worksite environmental patrols, which conduct in-house supervision regarding compliance with environmental laws and regulations at construction sites, conducted a total of 1,214 patrols at 695 construction sites throughout Japan. Patrol findings are shown in the graph. We took correction and prevention measures regarding the findings, and we are working continuously to make improvements.

Percentages of findings categories (FY2012)
Do Improve electronic manifest penetration rate

In the interest of proper disposal of waste material, we are promoting the computerization of paper manifests to prevent mistaken entries and omissions from manifests by emitting business operators, collection and transport business operators, and disposal contractors. We achieved a penetration rate of 85.9%* (civil engineering 79.0%* and construction 88.9%*) in fiscal 2012.

Do Proper disposal and rigorous control of spray-on asbestos and construction materials containing asbestos

We published a notice regarding measures to take in construction work that may cause dispersion of asbestos, and took measures to prevent dispersion of asbestos powder.
In addition, we began work to store the results of preliminary surveys on asbestos in demolition and repair work for a period of 40 years.

Do Thoroughgoing implementation of proper disposal and control of contaminated soil

On the real properties owned by TAISEI for marketing purposes, five surveys were conducted in fiscal 2012 on the basis of the Soil Contamination Countermeasures Act and other such statutes. There were two cases of countermeasure construction being implemented.

Do Complaints regarding construction sites and our responses

The main complaints received from neighboring areas regarding environmental issues at the construction sites of all our branches during fiscal 2012 are as follows, with their content and response measures taken.

Plan Improve Environmental Technology Research and Development and Proposal-Making Capability

Plan Comprehensive Environmental Activities

Do Implementation of Eco-Model Projects

Recipient of 2 Awards from the Minister of Land, Infrastructure, Transport and Tourism for Promoting Reduce, Reuse, Recycle Activities

The Midosuji shield construction site (Eco-Model Projects site, Osaka) and Keisei Sugano construction site (Chiba) each received an award from the Minister of Land, Infrastructure, Transport and Tourism for Promoting Reduce, Reuse, Recycle Activities given for active implementation of the three R's (reducing, reusing, and recycling) and ongoing activities.
The Midosuji shield construction site was recognized for its ingenious 3R activities utilizing the unique materials and facilities of shield tunnels and activities to reduce CO₂ emissions. The Keisei Sugano construction site was recognized for its activities to reduce CO₂ emissions by solar power generation and reduction in sludge production using the CRM (Continuous Walls Using Recycled Mud) method.

Do Expansion of Eco-Model Projects Overseas

In fiscal 2012, we attempted expanding Eco-Model Projects to overseas locations.
In Taiwan, we calculated the amount of CO₂ emissions at one civil engineering site, three building construction sites, and the office and discovered that the total amount of emissions was approximately 40,000 tons.

Do Assessing the Environmental Load Throughout the Supply Chain

In fiscal 2012, we joined the CDP Supply Chain Program hosted by CDP, an internationally recognized authority (British NGO). This program involves assessing the volume of carbon dioxide emissions (GHG Protocol, Scope 3) related to TAISEI's business activities at domestic and overseas business partner companies.
