■Preventing Global Warming and Saving Energy

All employees engage in activities to prevent global warming, covering everything from the telecommunications equipment that accounts for 96% of our carbon dioxide emissions to offices.

Initiatives to Prevent Global Warming and Save Energy

• Preventing Global Warming

  Power Purchases and Clean Energy Generation

  

  (Coverage: 12 Group companies)

  We have taken numerous steps to cut our carbon dioxide emissions to less than 370,000 metric tons by 2010.

  In fiscal 2006, we instituted measures to make our air-conditioning systems more efficient. The Tokyo Metropolitan Government’s Global Warming Measure Planning Report System presented a case study of this initiative. We are switching to direct current to power our telecommunication equipments to enhance energy efficiency. Although our total power consumption now covers 12 Group companies, up from seven in fiscal 2005, we have increased electricity usage by just 1.0%.

  In fiscal 2007, we will install gas air-conditioning system to lower

• Contributions to Team-6% Project

  The Team -6% project invites all citizens to help the nation fulfill its pledge to cut its greenhouse gas emissions by 6%.

  NTT Communications, NTTPC Communications, NTT Resonant, and Plala Networks participated in this project. Ongoing efforts include the 2 Up, 3 Down initiative through which people walk up two flights of stairs and down three instead of using elevators. Other contributions are to curb personal computer power consumption and turn off lights in vacant meet ing rooms. People can also wear CoolBiz fashions, enabling employers to run air conditioning at 28°C. We solicited participants in Team -6% through Kankyou-goo, which NTT Resonant operates.

• Planting Rooftop Gardens to Reduce Environmental Loads

  Rooftop vegetation on telecommunication building

  We are using rooftop gardens to reduce the heat island effect. Another benefit of these gardens is that they shield buildings from heat and reduces the power consumption of air-conditioning systems.

  In fiscal 2006, we planted Sedum creepers on the 473-square-meters rooftop of a telecommunications building in Tokyo. The vegetation reduces the facility’s annual carbon dioxide emissions by 13 metric tons. The creepers also help clean the air, improving living environments and beautifying views.

• Conserving Logistics Energy Consumption

  The revised Law Concerning the Rational Use of Energy implemented in April 2006 requires that parties providing and seeking transportation services endeavor to save energy. We annually audit transportation volume* based on invoices, sales promotion tools, and office waste. We voluntarily seek ways to streamline transportation and otherwise enhance logistics.

  We cut the use of transportation through our Web Billing service,which eliminates the need to post invoices. At the end of fiscal 2006,300,000 people used this service, up 40,000 from a year earlier. As a result, we reduced transportation volume about 160 ton kilometers.

  *Transportation volume = total of [cargo weight (metric tons) x transportation distance (kilometers)] per unit of shipped cargo
