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. For companies, making simultaneous efforts to mitigate and adapt to this issue is important.

KDDI's risk and opportunity

KDDI is aware of the risk of global warming and other climate changes, as well as large-scale natural disasters, and is taking the opportunity to mitigate and adapt to those 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 hindering the provision of stable information communication services. Meanwhile, we are taking the opportunity to provide ICT services by using equipment that has a lesser environmental load and developing and proposing services, solutions, and other efforts that reduce the movement of customers. Furthermore, ICT services have become a valuable means of communications during times of disaster functioning as a lifeline that society cannot do without. As such, we are constantly working to provide high quality information communications services 24 hours a day, 365 days a year.

KDDI's management

KDDI has in place 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. As of March 31, 2016, we are progressing in line with achieving the KDDI GREEN PLAN 2012-2016, barring one of the items.

Highlights of FY2015 Activities

We have calculated and released FY2012, FY2013, FY2014, and FY2015 emissions for Scope 3, which indicate the greenhouse gas emissions in the supply chain.
