CO₂ Emission Control Measures

Thermal power is a vitally important means of power generation for ensuring a stable supply of electricity by flexibly responding to fluctuations in power demand.
TEPCO Fuel and Power strives to reduce CO2 emissions through the use of LNG thermal power, a means of thermal power generation with comparatively low CO2 emission levels, and efforts to improve thermal efficiency for power generation.

Use of Clean Energy

LNG, a fuel producing with comparatively low CO2 emissions, accounts for the majority of fuel used in our thermal power plants.

Improving Thermal Efficiency for Power Generation

Improving thermal efficiency helps contain the use of fossil fuels in thermal power plants, reducing CO2 emissions.

TEPCO Fuel and Power actively adopts the use of highly efficient equipment and facilities as part of its efforts to improve thermal efficiency.

Initiatives Implemented to Achieve Benchmarks Set by the Act on the Rational Use of Energy

TEPCO Fuel and Power carries out initiatives to achieve benchmarks set by the Act on the Rational Use of Energy.

Benchmark Performance

Company performance on benchmarks set as standards for determining the rational use of energy as defined in the Act on the Rational Use of Energy are as described in the table below.
The Japanese Government has established an "energy mix" target for FY 2030 from a safety, energy security, economic viability and environmental perspective. To achieve these ends, we will strive to introduce highly efficient power generation facilities and maintain thermal efficiency levels in an aim to achieve standards for meeting the benchmark performance indicators set.

CO2 Emissions

CO2 emissions are calculated based on the "Act on Promotion of Global Warming Countermeasures".

Release of Company Reported Emission Levels in Accordance with the System for the Calculation, Report and Publication of Greenhouse Gas Emissions

Energy-originated CO2 emissions (CO2 emitted during fuel combustion, and CO2 emitted in the use of electricity or heat provided by another party) for "Businesses" defined in the system for the calculation, report and publication of greenhouse gas emissions based on the Act on Promotion of Global Warming Countermeasures, and for "Designated Energy Management Factories, etc." defined in the Act on the Rational Use of Energy are as described in the table below.

*"The Company" refers to the former Tokyo Electric Power Company below.
