Knowledge Practical Approaches for Global Carbon Neutrality （3/3）～KDDI’s Initiatives to Achieve Carbon Neutrality～

KDDI aims to reduce total CO₂ emissions (Scope 1 and 2) across the entire KDDI Group to practically zero by the end of fiscal 2030, and to achieve net zero by the end of fiscal 2040. In this context, “net zero” means reducing the overall CO₂ emissions across the entire supply chain (including Scope 3) to near zero.

In November 2013, KDDI launched a solar power generation project to contribute to CO₂ reduction. By constructing solar facilities on part of its own property, KDDI generates electricity that is sold to power companies under the “feed-in tariff system for renewable energy.”

In May 2023, KDDI and au Energy & Life began operating sustainable base stations that achieve virtually zero CO₂ emissions. On sunny days, these base stations autonomously secure their power supply through solar generation, meeting all of their energy needs.

At night, the power supply automatically switches to the carbon-free plan offered by au Energy & Life, ensuring low CO₂ emissions 24 hours a day, 365 days a year.

Successful global deployment of carbon neutrality requires concrete initiatives, such as phased planning (short-term, medium-term, and long-term), data integration, and local staff training. This article has highlighted the importance of flexible, site-specific approaches as well as the need for a clear vision from top management.

For overseas representatives advancing carbon neutrality, it is essential to begin by formulating a phased implementation plan with clear short-term, medium-term, and long-term objectives. Accurate monitoring of CO₂ emissions at all sites paves the way for effective reduction measures.

Next time we will focus on “solutions for visualizing CO₂ emissions” by introducing effective methods for data collection, reporting, and monitoring. Please stay tuned.
