Efforts to Reduce Environmental Impacts
in All Kinds of Areas
HEPCO implements a variety of environmental measures at its thermal power stations, such as measures to reduce the amount of SOx (sulfur oxide) and NOx (nitrogen oxide) contained in its gas emissions and to regulate the pH (a hydrogen ion concentration index) of its wastewater. HEPCO also conducts measurements and research to understand the impacts on surrounding areas, and in each case, confirms that there have been no impacts.
Promoting formation of a recycling-based society
With an aim of further improving its recycling rate for industrial waste, HEPCO is committed to promoting the 3Rs (Reduce, Reuse and Recycle).
Developing environmental relations activities
Together with local residents, HEPCO carries out cleanup activities along beaches and other areas, as well as tree-planting activities using special paper-made pots, which are easy to assemble and encourage seedlings to strike root.

To realize a sustainable society, on top of promoting measures against global warming, HEPCO is also pushing ahead with initiatives for reducing environmental impacts in other areas too.
