Carbon Neutrality
Management Approach
The TEPCO Group, as members of the Electric Power Council for a Low-Carbon Society (ELCS)*, promotes low-carbonization of energy to achieve our voluntary goals, by such efforts as improvement of expansion of renewable energy.
- *
Participation of 65 Japanese power operators in Japan (as of June 18, 2021), including the TEPCO Group
We will develop strategies for climate change, taking into consideration of the condition of restart of nuclear power, which greatly contributes to CO2 reduction.
Major Initiatives
| Segment | Details |
|---|---|
| Power generation | Installation of renewable energy power generation |
| Power distribution | System development towards expanding renewable energy installation, promoting installation of smart meters |
| Retail | Reducing CO2 emissions of electricity delivered to the customers by 50% or more by fiscal 2030 compared to in fiscal 2013, that is related to Scope 3 emissions |
[Voluntary Goals by the Electric Power Council for a Low Carbon Society (ELCS)]
Goals premising of realization of Japan's FY2030 energy mix
(prospect of long-term energy supply and demand)
| FY2020 | FY2030 | FY2018 actual | |
|---|---|---|---|
| Emission intensity (end use) | - | Approx. 0.37kg-CO2/kWh | 0.531kg-CO2/kWh |
| Maximum reduction potential by adopting BAT during installation of new thermal power plants | Approx. 7 million t-CO2 | Approx. 11 million t-CO2 | Approx. 8.5 million t-CO2 |
Targets and Initiatives for Carbon Neutrality
TEPCO* has grasped the global trend of decarbonization and is boldly shifting to a business model based on carbon neutrality.
FY2030 target :
Reduce CO2 emissions of electricity delivered to customers by 50% in FY2030 compared to FY2013
2050 challenge :
Reduce CO2 emissions from the supply of energy to net zero by 2050
With these objectives in mind the entire Group is engaged in initiatives to both develop zero-emission power sources and further promote the electrification of energy demand so that we can work with society to achieve carbon neutrality.

[Society] Achieving Carbon Neutrality with Our Customers
Initiatives on the energy demand side, such as developing emission-free power sources and replacing fossil fuels with "electrification," etc., are important for achieving carbon neutrality.
TEPCO is working with our customers to improve energy resilience during emergencies, live more comfortably, and achieve carbon neutrality.
[Grids] Smart Systems for Supporting Carbon Neutrality
Transmission and distribution networks play an important role in the introduction of large amounts of renewable energy. And, they need to be more resilient to natural disasters which are becoming fiercer and affecting larger areas.
In order to achieve carbon neutrality and strengthen the resilience of power grids, we will leverage digital technology to increase the value of regionally dispersed energy, and make changes to both equipment and facility configuration in order to more effectively utilize dispersed transmission and distribution networks.
[Supply] The Best Mix for Carbon Neutrality
Zero-emission power sources are needed if we are going to achieve carbon neutrality. However, in Japan, which has few natural resources, it is important to balance energy security with economic efficiency while prioritizing safety. As an energy provider, TEPCO is aiming for a best mix of energy in order to achieve carbon neutrality that is based on the S+3E's.
