Environmental Indices (performance & targets)

We have selected key areas to be prioritized and set key environmental management indices measuring the extent to which we achieve these priorities. Quantitative targets have been set to the extent feasible. We periodically check our progress in achieving these targets.
In the future as well, the entire HEPCO Group will work together to expand such initiatives so that we may reach these targets.

[Evaluation index]

Evaluation index

  1. *1Calculated based on the Greenhouse Gas Emissions Accounting, Reporting, and Disclosure System pursuant to the Act on Promotion of Global Warming Countermeasures.
  2. *2Values reflect adjustments and other corrections associated with CO2 credits, non- fossil fuel value certification purchases, and Feed-in Tariffs (FIT) for renewable energy sources.
  3. *3Figure does not include power station and substation power consumption, transmission/ distribution loss, or other electric power used when supplying electricity.
  4. *4Figure covers industrial waste generated by HEPCO and electric power supply- related businesses of HEPCO Group companies.
  5. *5Items counted: The procurement rate is indicated for environmentally-friendly copy paper, printed materials (excluding flyers, posters and pamphlets), OA equipment and clothing products which vendors publish in their catalogs or other such publications. Copy paper is only counted for HEPCO Group companies.
