Environmental Management

Results and Assessments for Goals in Fiscal 2008

To achieve the NTT Group Principal Activity Plan Targets for reducing our environment impacts by fiscal 2011, every year we analyze achievement levels against specific goals for the three areas of preventing global warming, reducing waste products, and reducing paper consumption, and use our findings to implement improvements.

Progress made on the NTT Group Principal Activity Plan Targets*1 (by fiscal 2011)

Prevention of global warming*1
Goals
  • Reduce CO2 emissions per subscriber by at least 35% based on fiscal 1991 levels for all telecommunications carriers.
    (Telecommunications carriers: NTT East, NTT West, NTT Communications, NTT DOCOMO)
  • Reduce CO2 emissions per unit of sales by at least 25% based on fiscal 1991 levels for all other Group companies.
    (Other Group companies: NTT DATA, NTT COMWARE, NTT FACILITIES, etc.)

*1 Achievement level for reducing global warming is assessed as the five year average for fiscal 2009-2013.
Specific activities
  • Reduce electricity consumption through the Total Power Revolution (TPR) campaign.
  • Reduce CO2 emissions in logistical and sales operations.
Results
(in graphs)

CO2 emissions reduction rates of NTT telecommunications carriers and other Group companies rose.
Compared with the previous year, CO2 emissions reduction rates rose as a result of our deployment of energy-efficient communications equipment, efficient building and operation of communications facilities, careful examination of CO2 emissions calculations and correction of duplicated calculations within the Group, and improvement of the CO2 emissions conversion coefficient*2 for electricity usage.
Due to revisions made in fiscal 2009 to Japan's Law Concerning the Rational Use of Energy and Law Concerning the Promotion of the Measures to Cope with Global Warming, companies in Japan are now mandated to manage energy usage (and emissions levels) on an individual company basis. To comply with these legal revisions, the NTT Group is reviewing the scope of its data collection procedures, looking into setting new energy-related targets, and implementing further reduction measures.

CO2 emissions reduction rates of telecommunications carriers (base year: fiscal 1991)
This is a graph showing CO2 emissions reduction rates of NTT telecommunications carriers over the past four years. The reduction rate for fiscal 2008 was 27.4%, a 5.2% improvement over fiscal 2007.

CO2 emissions reduction rates of other Group companies (base year: fiscal 1991)
This is a graph showing CO2 emissions reduction rates of Group companies other than telecommunications carriers over the past four years. The reduction rate for fiscal 2008 was 28.6%, a 4.6% improvement over fiscal 2007.

CO2 emissions from business operations
This is a graph showing CO2 emissions from business operations over the past five years. CO2 emissions for fiscal 2008 amounted to 3.6 million tons-CO2, a decrease from last year of 180,000 tons-CO2.

*2 Coefficients used for calculating CO2 emissions based on levels of power consumed were 0.378 kg/kWh for fiscal 2004-2005 and 0.555 kg/kWh for fiscal 2006. For fiscal 2007-2008, the coefficients of respective power suppliers were used.

Waste reduction
Goals
  • Reduce amount of final disposal waste to no more than 15% of fiscal 1991 levels.
Specific activities
  • Reduce the amount of final disposal waste through reduce, reuse, and recycling efforts.
Results
(in graphs)

Amount of final disposal waste* declined and reduction target was cleared.
Efforts to expand IP related equipment and base stations for 3G mobile phones resulted in more waste output compared with the previous year, but gains in recycling efficiency limited the rise in final disposal waste to only 31,000 tons, enabling us to meet our waste reduction targets for the year.

Waste output and final disposal waste
This is a graph showing waste output and final disposal waste over the past five years. Waste output for fiscal 2008 was 782,000 tons, an increase of 103,000 tons over fiscal 2007, but final disposal waste fell to 31,000 tons, clearing the NTT Group's reduction target.

* Waste disposed of in landfills

Reduction in paper use
Goals
  • Reduce consumption of virgin pulp to no more than 80% of fiscal 1991 levels.
Specific activities
  • Reduce paper use by recycling telephone directories.
  • Reduce paper use through Internet billing statement services.
Results
(in graphs)

The amount of virgin pulp used cleared our reduction targets for the year, but rose slightly compared with the previous year.
The virgin pulp content of office paper increased significantly due to discrepancies in the amounts of recycled pulp content found in paper supplied by manufacturers. There was no discrepancy in actual recycled pulp content for telephone directories, enabling virgin pulp usage to be reduced by 21,000 tons. Despite total consumption increasing slightly to 32,000 tons, our virgin pulp paper reduction goals were still cleared.

Virgin pulp consumption
This is a graph showing virgin pulp consumption over the past five years. Consumption for fiscal 2008 was 32,000 tons, clearing the Group reduction target but increasing by 3,000 tons over fiscal 2007.

- In fiscal 2007 billing statements were also included in assessments of virgin pulp consumption.

This point is about three sevenths of the way down the page.

Environmental accounting

The NTT Group introduced environmental accounting in fiscal 2001 to boost the efficiency and effectiveness of its environmental conservation efforts by quantitatively determining both the cost of environmental conservation programs undertaken as part of its business activities and the returns gained. In fiscal 2008, higher levels of recycling pushed up our recycling costs by about ¥9.1 hundred million compared with fiscal 2007, but these efforts allowed us to boost the amount of recycled waste by nearly 100,000 tons. A cost saving of 27.41 billion yen was also achieved through the reuse of certain resources.

We are determined to further improve our environmental management through quantitative measurement and analysis of our environmental activities.

1. Scope of data

The companies subject to consolidated environment accounting are NTT, NTT East, NTT West, NTT Communications, NTT DATA, NTT DOCOMO, and their group companies (192 companies in total).

2. Applicable period

Data for fiscal 2008 report is from April 1, 2007 to March 31, 2008
Data for fiscal 2007 report is from April 1, 2006 to March 31, 2007

3. Accounting method

  • Accounting is based on the NTT Group Environmental Accounting Guidelines.
    These guidelines comply fully with the Environmental Accounting Guidelines 2005 issued by the Ministry of the Environment.
  • Environmental conservation costs are expressed in monetary units and conservation benefits in monetary units and physical quantity.
  • Environmental conservation costs are tabulated separately as environmental investments and environmental costs. From fiscal 2004, depreciation costs are included in environmental costs. Personnel costs are also included in environmental costs.
  • Reductions in CO2 emissions through energy conservation measures are calculated by subtracting actual emissions from estimated emissions in the event that no such measures were taken.
