The TEPCO Group contributes to creating a sustainable society by setting forth principles of environmental conservation activities in the TEPCO Group Basic Environmental Philosophy and promoting environmental activities appropriate to the respective business operations of each Group company, under the awareness that the Group has the social responsibility to give serious thought to issues of environmental importance such as global warming and biodiversity conservation.
TEPCO Group Basic Environmental Philosophy
The TEPCO Group will:
- Fulfill social responsibilities as a business enterprise to pave the way for sustainable development in the 21st century, by taking positive measures for the solution of environmental problems, including global warming;
- Endeavor to achieve the reduction of environmental risks, including air pollution control, by continually improving the environmental management system, while carrying out eco-efficient business activities with consideration given to the reduction of CO2 emissions, waste recycling, and energy and resource conservation; and

Relationship between business activities and the environment
The electricity business forms the core of the TEPCO Group, and involves the input of diverse resources to generate power and produce electricity, and the output of environmental loads and waste. To minimize the consumption of resources and environmental burden, we are striving to increase power generation efficiency, promote waste recycling, and reduce air pollutants. We are also making active efforts to protect, conserve and create nature environments around our power plants and in Oze, so that we may pass down a rich and diverse natural legacy to the next generation.

*2 Radioactive waste is reported as cumulative amounts of low-level and high-level radioactive waste in storage, because yearly results fluctuate for reasons other than power generation status, such as compaction by compression and incineration (low-level waste) and shipping to and from overseas points for reprocessing (high-level waste).
Cumulative amount of low-level radioactive waste in storage: Cumulative amount in storage at the Fukushima Daiichi, Fukushima Daini, and Kashiwazaki-Kariwa Nuclear Power Stations, as of March 31, 2010
Cumulative amount of high-level radioactive waste in storage: Number of canisters (stainless steel containers about 0.4 m in diameter and about 1.3 m high) returned from France and stored by Japan Nuclear Fuel Limited at its Vitrified Waste Storage Center (Rokkasho-mura, Aomori Prefecture), as of March 31, 2010
*3 Power transmitted = power generated + power purchased from other companies - power for pumping water - power used in power stations
