Environmental Guidelines

NTT Group operations have the following four key attributes: (1) procurement of a great many products; (2) possession of many buildings; (3) high electricity consumption by telecommunications equipment; (4) in-house R&D facilities. To promote the effective reduction of our environmental impacts, we have drafted the following original standards and guidelines that address each of these four key attributes.

In particular, the development and procurement of ICT devices with outstanding energy efficiency is essential for the effective reduction of the CO₂ emissions of the NTT Group.

Under the Green Procurement Standards, the NTT Group develops and procures ICT devices such as routers and servers with consideration for energy-efficient performance in addition to function, performance and cost as well as target values for each equipment. We are endeavoring to apply these initiatives to the reduction of electricity consumption and concomitant CO₂ emissions related to customer communications.

Pursuing Initiatives across the Industry for Energy-Efficient ICT Devices

NTT is a member of the Telecommunications Carrier Association (TCA) and in that capacity, participates in the ICT Ecology Guideline Council,^*1 an organization that seeks to enhance the energy efficiency of telecommunications-related products. The council formulates guidelines on the criteria for evaluating the energy efficiency of telecommunications devices, and NTT has contributed to the technical aspect of this effort. The NTT Group's Energy Efficiency Guidelines were based on the guidelines created by this council, and the content of these guidelines is now included in the Green Procurement Standards.

In August 2010, eight NTT Group companies^*2 acquired the Eco ICT Logo on submitting self-evaluations of their CO₂ emissions reduction efforts, including the establishment of Energy Efficiency Guidelines. The Eco ICT Logo was created by the ICT Ecology Guideline Council to signify efforts by telecommunications service providers to reduce CO₂ emissions.

Eco ICT Logo

We will continue to drive the development and procurement of energy-efficient equipment, and work with the ICT Ecology Guideline Council to help bring both vendors and carriers together to promote the industry-wide procurement of energy-efficient equipment. We will ensure that vendors are consistently provided with requirements for NTT Group specification processes, and include energy efficiency information disclosure and our corporate stance on energy efficiency in our criteria for selecting vendors.
