Promotion of Greenhouse Gas Reduction Projects

As a supplementary action to our own CO₂ reduction measures, TEPCO promotes greenhouse gas emission reduction projects in cooperation with foreign countries and domestic small and medium sized enterprises by providing technical and financial support, and consequently contributes to creating a low-carbon society.

Utilization of the Kyoto mechanisms*

We actively utilize the Kyoto mechanisms based on the awareness that they could more efficiently reduce greenhouse gases compared to reduction initiatives in Japan, and could also contribute to sustainable development in developing countries. The carbon credits we acquire through the Kyoto mechanisms are used toward attaining our voluntary reduction target for CO₂ emission intensity.

* Kyoto Mechanisms
These mechanisms allow developed countries to reduce greenhouse gases on a global scale in cooperation with other countries, by using the emission reduction amounts or initial allowances of developed countries to attain their respective emission reduction target under the Kyoto Protocol. The mechanisms include Joint Implementation (JI), Clean Development Mechanism (CDM), and International Emissions Trading, and the reduction amounts and initial quota that are transferred through these mechanisms are called carbon credits.

• Wind power generation CDM project in Guangdong Province, China

TEPCO is a participant in the wind power generation project with the approximate capacity of 100MW, operated by Guangdong Yudean Shibeishan Wind Power Development Co., Ltd. in a coastal region of Huilai County, Jieyang City in Guangdong Province. The project contributes to reduce CO₂ emissions by replacing electricity generated by fossil fuel fired power plants.
We have first acquired the carbon credits generated from the project in April 2009, worth approximately 42,000 tons.

• Participation in the Japan GHG Reduction Fund*

We acquire carbon credits by investing in the Japan GHG Reduction Fund (JGRF). In November 2009, we received our share of carbon credits from CDM project for introduction of power regenerative braking technology in Delhi Metro System, India. In the project activity, the motors installed in the rolling stock regenerate electricity during braking and regenerated electricity is used by other rolling stocks on the same service line. It is expected that electricity consumption is reduced by approximately 30% from conventional levels and the project activity contributes to CO₂ emission reduction.

* Japan GHG Reduction Fund
The first carbon fund in Asia established by 33 private companies and organizations in Japan in December 2004, as a framework for acquiring carbon credits.

Utilization of the Domestic credit system*

We also utilize the domestic credit system to help domestic small and medium enterprises reduce CO₂ emissions. We expect to reduce CO₂ emissions in the amount of 25,000 tons from 7 projects supported by us between FY2008 and FY2012.

* Domestic credit system
A system that allows large companies that have contributed to the reduction of CO₂ emissions by small and medium enterprises through financial and technical support to use that CO₂ reduction amount as their own reduction to fulfill their voluntary targets and action plans. The system was launched in 2008.

• CO₂ emission reduction project at a hospital

We are implementing a CO₂ emission reduction project at Kashiwa Rehabilitation Hospital in Kashiwa City, Chiba Prefecture in cooperation with Aoikai Medical Corporation. The project aims to increase energy efficiency and reduce CO₂ emissions by replacing gas heat pumps with high-efficiency electric heat pumps, and gas-fired hot water boilers with high-efficiency electric water heaters.

By implementing the project over a period of 4 years, from FY2009 to FY2012, we expect to acquire approximately 2,284 tons’ worth of domestic carbon credits.

• CO₂ emission reduction project at tomato farms

In Tochigi City and Shimotsuga County, Tochigi Prefecture, we are implementing a CO₂ emission reduction project in tomato greenhouses at Sunfarm Oyama and Green Stage Ohira, in cooperation with Shimotsuke Agricultural Cooperative. The project aims to reduce CO₂ emissions by replacing heavy oil-fired heaters with high-efficiency electric heat pumps for gardening purposes.

By implementing the project over a period of 5 years, from FY2008 to FY2012, we expect to acquire approximately 1,353 tons’ worth of domestic carbon credits.
