Contribution to a Low-Carbon Society

Management Approach

The TEPCO Group, as members of the Electric Power Council for a Low-Carbon Society* , promotes low-carbonization of energy to achieve our voluntary goals, by such efforts as improvement of thermal efficiency at our thermal power generations and expansion of renewable energy.
*participation of 42 Japanese power operators in Japan (as of April 5, 2017), including the TEPCO Group
We will develop strategies for climate change including quantitative targets, taking into consideration of the condition of restart of nuclear power, which greatly contributes to CO2 reduction.

Major Initiatives

Segment Details of installation
Power generation Installation of high-efficiency thermal power generation (MACCII, IGCC, etc.), installation of renewable energy power generation
Power distribution System development towards expanding renewable energy system, promoting installation of smart meters
Retail Propose and provide optimal energy use for customers, promote dissemination of heat pumps and other high-efficiency equipment

Energy consumption intensity for buildings, etc.*

FY2015 FY2016
MJ/m2 - 1,427
  • *

    Energy consumption intensity
    = office building energy consumption (MJ) / surface area of that office building (m2)

  • *

    Energy included in intensity is fuel, electricity, heating, and cooling.

Reduction in energy consumption achieved

Improvement of thermal efficiency of all thermal power plants by 1% has a CO2 reduction effect of 1.9 million tons.
From 2015 to 2016, thermal efficiency at thermal power plants was improved by 0.8%.

Reductions in energy requirements of sold products and services achieved

Due to the characteristics of our business, the products and services we provide do not require energy consumption. Thus, there are no changes in energy requirements.

GHG emissions and energy consumption within the organization

GHG emissions (Scope 1)

Unit FY2015 FY2016
YoY
CO2 From power generation Kt-CO2 91,300 88,900 -3%
  • *

    CO2 emissions are due to the consumption of fuel used for power generation at the TEPCO Group's thermal power plants.

  • *

    No CO2 emissions from bio-fuel

FY2016 SF6, HFC, and other GHG emissions incidental to TEPCO Group business activities

Unit FY2015 FY2016
YoY
HFC Kt-CO2 3.0 4.0 33%
SF6 (Sulfur hexafluoride) Kt-CO2 60.0 61.0 2%
Methane Kt-CO2 0 0 -
N2O (Dinitrogen monoxide) Kt-CO2 58.0 58.0 -
  • *

    No CO2 emissions from bio-fuel.

  • *

    We selected the stock equity method as the consolidation approach for the calculation of emissions.

  • *

    As a reference for calculation, we used the "System for Calculating, Reporting, and Publishing Greenhouse Gas Emissions" based on the Act on Promoting Global Warming Countermeasures.

GHG emissions (Scope 2)

CO2 emissions incidental to indirect energy consumption (buildings, etc.) for TEPCO Group business activities

Unit FY2015 FY2016
YoY
CO2 Kt-CO2 - 87.0 -
  • *

    CO2 emission is calculated using the energy consumption of the office buildings that are classified as 3300 in the industrial classification by the Act Concerning the Rational Use of Energy (Energy Conservation Act).

  • *

    We selected the stock equity method as the consolidation approach for the calculation of emissions.

GHG emissions intensity

    ( ) indicates CO2 emissions intensity and CO2 emissions prior to reflecting adjustments stipulated in the Feed-In Tariff for Renewable Energy based on the Act on Promoting Global Warming Countermeasures.

  • *

    Values in FY2015 is of TEPCO Inc., and values in FY2016 is of TEPCO Energy Partners Inc.

  • *

    The Feed-In Tariff stipulates that all power users bear surcharges to the electricity used, and thus all the environmental value be fairly distributed to power users. Values of CO2 emissions intensity and CO2 emissions are calculated in accordance with the provisions of the relevant regulation.

  • *

    The CO2 emissions is the emissions from the consumption of fuel used for power generation at thermal power plants, and includes electricity purchased from other companies.

GHG emissions and energy consumption outside of the organization

Energy Consumptions outside of the organization (Scope 3)

Energy consumed outside of the organization is extremely limited compared to internal energy consumption and there is no appropriate calculation method thus we eliminated energy consumption outside of the organization from calculation and reporting.
