KDDI's Approach

Recognition of Social Issue

In these times when global warming is evident, along with measures to mitigate global warming by reducing greenhouse gas emissions, people are asking about adaptations to global warming where nature and society are changing in response to the effect on the global environment. In 2015, the Paris Agreement was established, calling for a global effort to hold the global temperature rise since the industrial revolution to less than 2°C and to strive to limit the increase to less than 1.5°C. For companies, making simultaneous efforts to mitigate and adapt to this issue is important.

KDDI's Risk and Opportunity

KDDI is aware of the risks of climate change and large-scale natural disasters, and is taking the opportunity to mitigate and adapt to these risks. Global warming increases the risk of natural disasters, which greatly increases the chance of damage or disruption to communications equipment and interruption of communications, thereby hindering the provision of stable information communications services. Meanwhile, we are taking the opportunity to provide ICT services such as those that use equipment with a lesser environmental load, and those that contribute to the development of services and solutions that reduce the movement of customers.

KDDI's Management

KDDI has established the KDDI GREEN PLAN 2012-2016 Medium-term Environmental Conservation Plan based on the KDDI Environmental Charter, and the KDDI Action Guidelines on the Preservation of Biodiversity based on this Medium-term Environmental Conservation Plan. All but one of the targets in the KDDI GREEN PLAN 2012-2016 was achieved. Since FY2017, KDDI has established a new KDDI GREEN PLAN 2017-2030 based on the previous results, and will pursue efforts to make use of ICT services in Climate Action, Creating a Recycling-Oriented Society, and Conservation of Biodiversity.

Highlights of FY2016 Activities

Environmental Conservation Plan

FY2016 was the final year of the KDDI GREEN PLAN 2012-2016 Third Medium-term Environmental Conservation Plan, which KDDI established in FY2012. This plan took three material issues―Low-carbon society, Recycling-Oriented society, and Biodiversity―and established concrete targets for each. To achieve these targets, KDDI promoted the 3G―Green of ICT, Green by ICT, and Green Road Project.

Future issues

  • 7% reduction in CO2 emissions in FY2030 compared to FY2013 for KDDI (in Japan, non-consolidated)
  • Upgrading to highly energy-efficient data centers in Japan and abroad
  • Contributions to reductions in society's CO2 emissions by providing KDDI's information and communication technology (ICT) services
  • Maintain zero emissions from retired telecommunication facilities
  • Maintain material recycling rate of 99.8% for used mobile phones
  • Active promotion of initiatives using ICTs to conserve ecosystems
