Environmental Conservation Activities ・ Environmental Data

We have established concrete targets to achieve medium-to-long-term environmental goals in EPC, Office and R&D activities.In addition to contributing to the environment through our core business in Japan and overseas, we proactively carry out environmental activities, including assessing the main environmental impacts at our offices and construction sites, promoting recycling, and practicing green procurement.

Environmental Activity Categories

Chiyoda's main operations are in the engineering, procurement and construction (EPC) of plants/facilities, project management with the related support services and research and development. We categorize these operations into EPC, Office and R&D activities, as shown in the diagram below, which also correspond to our environmental activity categories.

EPC Activities

Chiyoda establishes annual environmental goals for each of its specialized engineering and procurement departments based on the environmental targets shown below. Self-evaluations of performance at the end of the first half and the full fiscal year are applied to the following fiscal year's activities.

<>

Target 1 -- Offer Proposals for Improving Environmental Performance to Customers

Example of environmental solution

Made an average of 2.40 environmental proposals per EMS project in Japan.
Made an average of 3.93 environmental proposals for projects where environmental proposals were made.
Of the Company’s six SQE* Management Activities Awards given in the fiscal year ended March 2011, the Technology Planning & Administration, Technology Development Business Planning & Administration Office and IT Management Office won a special prize for excellence for promoting a pilot program for paperless meetings companywide; the Construction Division received a special award for environmental protection by reusing old ID cards; and the Pharmaceutical Project Department /Mechanical Engineering Centers 1 & 2 received a merit award for promoting and implementing environment-conscious solutions for customers.
* SQE: Occupational safety, quality and environment.

Target 2 -- Assess and reduce output of construction by-products and achieve zero emissions. (Final landfill quantity less than 5 percent of initial disposal quantity)

The ratio of final landfill quantity to initial disposal quantity for construction sites in Japan during the fiscal year ended March 2011 was 18.0 percent for non-sludge, 4.4 percent for sludge and 17.2 percent overall. This was attributable to a lack of progress in recycling due to factors such as a high volume of insulation waste, debris and other hard-to-recycle waste generated due to demolition work on existing plant facilities.

※Note: Starting from the fiscal year ended March 2011, residue after incineration is estimated at 7 percent of pre-incinerated waste volume and added to final landfill quantity.

Target 3 -- Promote use of electronic manifests (Goal is 88% of all manifests)

Electronic manifests accounted for 89.7 percent of all manifests used on construction sites in Japan during the fiscal year ended March 2011, meeting Chiyoda's target.

Target 4 -- Promote inspection of industrial waste disposal sites (Target inspection rate of 50%)

At domestic sites, site inspections were conducted at waste disposal sites of 23 percent of waste disposal sites/waste processing. The low inspection rate was attributable to the difficulty in conducting actual inspections because disposal sites are located far from construction sites.
The revised Industrial Waste Disposal Law enacted in April 2010presents multiple methods of obtaining information on the disposal performance of waste disposal sites/waste processing. Chiyoda therefore plans to use modified verification methods in the fiscal year ending March 2012.

Office Activities

<>

Target 1 -- 100% clean desks and 33% reduction in printed documents

Clean desks: 93.7 percent target achievement
Reduction in printed documents: 169 percent target achievement

As in the previous year, Chiyoda set a target for the priority issue of reducing printed documents, and made steady progress. Cleaning up archives and other measures resulted in a 169 percent achievement rate, well exceeding the target. The volume of documents reduced was 13,681 cardboard boxes (6,311 file meters, or 213 tons), equivalent to 4,260 trees (140mm in diameter and 8m tall).

Target 2 -- Reduce recyclable trash and waste by 10%

Reduction of documents was achieved mainly by recycling paper and by cleaning and re-using file folders and other office supplies.
Approximately 47,100 files, 29,300 binder clips (large, medium, small) and 69,900 colored index tabs

Target 3 -- Encourage employees to dress for the season

Made steady progress in encouraging employees to wear warm- and cold-weather business attire.

The following are principal examples of Chiyoda’s new energy conservation activities during fiscal year ended March 2011.

Renewal of low-voltage transformation facilities (Koyasu)

The transformer in low-voltage transformation facilities that was installed more than 27 years ago was replaced with a high-efficiency transformer as part of an overall upgrade of facilities. The new transformer is the “top-runner” type recommended by the Japanese government, and will reduce electricity consumption and CO2 emissions. Chiyoda plans to follow with renewals of its high-voltage transformation facilities.

Central Monitoring System for Air-Conditioning (Koyasu)

A building management system has been installed in the central control office of the main building to simultaneously verify the amount of energy being used throughout the building and the effect of energy-saving facilities.
This system monitors electric power consumption, air- conditioning operation and other measurements, which has facilitated planning and demonstration of energy-efficient operation.
Preparation of materials such as monthly and yearly data from these facilities and reports to government agencies are also possible.

Research and Development Activities

The following are principal examples of activities conducted to achieve research and development targets for the fiscal year ended March 2011

<>

Target 1 -- Reduce laboratory waste. Predict volume of laboratory waste from past results and current year operations and set targets

Laboratory at the Koyasu Office & Research Park
(preparing a catalyst)

For industrial waste generated by research and development, Chiyoda predicted the amount of waste based on past results and the content of research and development expected to take place during the fiscal year, and acted to reduce the predicted volume by 5 percent. The actual reduction was under 5 percent, mainly because disposal of stored waste generated in the past exceeded assumptions. Chiyoda intends to further reduce industrial waste by separating general wastes.

Target 2 -- Ensure complete compliance with laws concerning research and development

In the fiscal year ended March 2011, Chiyoda once again set compliance with laws regarding items such as research equipment used in research and development as an environmental target, and carried out activities to achieve it. Specifically, we surveyed government notifications for research equipment based on the relevant laws to confirm that results were in compliance with legal requirements. In the fiscal year ended March 2011, Chiyoda focused on the Industrial Safety and Health Act, and conducted surveys and studies that also included other related laws. As a result, we reconfirmed that there were no problems in notifications to government agencies, management methods or other areas.
