In accordance with the HEPCO Group Environmental Policy, we have set environmental management items that constitute specific initiatives to reduce the burden that we place on the environment in various business sectors. Each fiscal year, targets are set for these environmental management items and our progress and results assessed, which are then fed back into planned and continuing efforts. In FY2024, we specified target levels for office electricity and water usage as well as the emissions intensity per 1kWh for SOX (sulfur oxide) and NOX (nitrogen oxide), for which qualitative targets had previously been set. We decided that quantitatively presenting targets helps build stronger awareness among employees and enables us to objectively measure the degree of achievement.
