Our group target for reducing CO2 emissions to help create a low carbon society is to curb our emissions in Japan by at least 2 million t- CO2 from the projected 2020 level so as to reduce total emissions by at least 15% (600,000 t- CO2) from the fiscal 2009 level (using the Federation of Electric Power Companies of Japan's 0.33 kg/kWh as the emission coefficient for setting the fiscal 2021 target). Our CO2 emissions for fiscal 2012 were 3.79 million tons, a year-on-year reduction of about 30,000 tons.

CO2 emissions from business operations

Over 90% of the CO2 emissions created by NTT Group business operations are attributable to office and communications equipment power consumption. The NTT Group accordingly created a groupwide energy conservation strategy called Total Power Revolution (TPR) in October 1997 to reduce its power consumption. By promoting efficient energy management at buildings owned by NTT and installing energy-efficient electrical power units, air conditioning systems and telecommunications equipment, we managed to reduce power consumption across the NTT Group by 460 million kWh in fiscal 2012 compared with fiscal 2011.

The NTT Group has been implementing its Green NTT plan to promote the use of eco-friendly renewable energy since May 2008. The goal of this plan is to expand our use of solar power, which could be seen as a key symbol of the low carbon society. Our target is to deploy a total of 5 MW of solar power systems over the whole Group by fiscal 2013.

In August 2008, we established NTT-Green LLP, a limited liability partnership charged with the task of driving the Green NTT plan. NTT-Green LLP is pushing ahead with the efficient installation of solar power systems in premises owned by group companies, and by investing and participating in NTT-Green LLP, group companies can contribute to the spread of renewable energy use. With the approval of a third party certification authority, NTT-Green LLP also issues Green Power Certificates to investing companies, according to the amount of power generated in line with the amount invested. This is the first environmental project undertaken by a business group LLP in Japan that combines the deployment of solar power systems with the issue of Green Power Certificates.

In fiscal 2012, three new solar power generation facilities were added to the Group's stock, and went into operation. The eight facilities installed since fiscal 2010 generate a total of approx. 1.7 MW of power. These combined with systems deployed by individual companies brought the total number of NTT Group systems in operation nationwide to 161 as of the end of fiscal 2012, with a total generating capacity of about 4.5 MW. We are now almost within reach of our target of 5.0 MW by the end of fiscal 2013.

Moving forward, we will endeavor to continue to play a leadership role in contributing to the creation of a low carbon society through the expansion of renewable energy generation in Japan.

Eco ICT Logo

The development and procurement of ICT devices with outstanding energy efficiency is essential to effectively reducing the CO2 emissions of the NTT Group.

We accordingly organized our basic philosophy and devicespecific targets with respect to the development and procurement of routers, servers and other ICT devices used in group companies into our NTT Group Energy Efficiency Guidelines, and we have applied these guidelines since May 1, 2010. These guidelines give concrete form to the ICT devicerelated energy-saving stipulations of our NTT Group Guidelines for Green Procurement and NTT Group Green R&D Guidelines.

Based on these Energy Efficiency Guidelines, group companies develop and procure ICT devices that pay due consideration to energy efficiency as well as to functionality, performance and cost. We are also endeavoring to apply this initiative to the reduction of electricity consumption and concomitant CO2 emissions related to customer communications.

In August 2010, eight NTT Group companies^*1 acquired the Eco ICT Logo on submitting self-evaluations of their CO2 emissions reduction efforts, including the establishment of these guidelines. The Eco ICT Logo was created by the ICT Ecology Guideline Council^*2 to signify efforts by telecommunications service providers to reduce CO2 emissions.

Following the Council's announcement of its Ecology Guideline for the ICT Industry Version 3, the NTT Group revised its own Energy Efficiency Guidelines accordingly and announced Version 3 in February 2012.
