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 electric power usage related to electric power supply, including inside power stations and substations as well as transmission/distribution loss.
  4. *4Figure covers industrial waste generated by HEPCO and businesses associated with HEPCO Group companies which are involved in supplying electric power.
  5. *5Of the items covered that are copy paper, printed materials (excluding flyers, posters and pamphlets), OA equipment and clothing, the procurement rate is indicated for environmentally-friendly products which vendors publish in their catalogs or other such publications. Only copy paper is counted for HEPCO Group companies.
