Environmental protection activities/Realizing a Low Carbon Future

Low CarbonRealizing a Low Carbon Future

To realize a low carbon future and adapt to the effects of climate change, we have set three targets leading up to fiscal 2031. These are reducing overall CO2 emissions across society, improving telecom power efficiency, and adapting to climate change.

Reduction of CO2 Emissions across Society
We will contribute to reducing the CO2 emissions of society by at least 10 times more than the NTT Groupís own emissions.


We will seek to curb our own CO2 emissions (red ball) generated by the NTT Groupís businesses while contributing to overall reductions in CO2 emissions across society (green ball) through the provision of services and technologies.


  • Provide services and technologies that contribute to the reduction of CO2 emissions across society
  • Promote R&D that contributes to reducing CO2 emissions
  • Disseminate examples of contributions made inside and outside the Company

Reduction of CO2 Emissions across Society

Improvement of Telecom Power Efficiency
We will raise power efficiency per data transmission in our telecommunications businesses by at least 10 times compared to fiscal 2014 levels.


We will seek to raise the efficiency of our electricity use, which is essential for us to continue our business. Achieving this target will also contribute to reducing CO2 emissions since electricity is the primary cause of our CO2 emissions.


  • Reduce energy consumption of communications equipment
  • Raise efficiency of communications facilities including networks and data centers
  • Promote R&D that contributes to energy conservation

Improvement of Telecom Power Efficiency

Adaptation to Climate Change
We will play our part in adapting to climate change by actively promoting initiatives through all our activities and by collaborating with our stakeholders.


We will take action on climate change by adapting as a means of moderating its effects that have already materialized and those that will be unavoidable in the mid- to long-term.


  • Disseminate examples of adaptation inside and outside the Company
  • Promote R&D that facilitates adaptation to climate change
  • Engage in initiatives with employees of the Group as well as with customers and business partners

Adaptation of the NTT Group:Developing disaster-resilient telecommunications networks and equipment

The NTT Group is striving to develop disaster-resilient telecommunications networks and equipment. These measures are aimed at mitigating the effects of disasters, and we will also continue providing communications services in the event of a disaster, while serving as an example of adaptation to disasters caused by climate change.

Adaptation of society by providing ICT:Mobile ICT unit

We provide mobile boxes and automobiles equipped with communications, information processing and storage functions to enable the swift recovery of communication functions in areas affected by a disaster. We also offer functions for collecting data on the people affected. These services are disaster prevention measures and adaptation to disasters caused by climate change.
