Reduction of impact on roadside living environment

In order to reduce the impact on the roadside environment, we are taking measures such as noise countermeasures by installing sound insulation walls and maintenance of environmental facility zones.In fiscal 2019, we installed sound insulation walls of about 3 km, and the total length of installation is about 1,080. It is km.

Promotion of environment-friendly "eco Inter ®" and "eco Area ®"

At IC and SA / PA, based on the active introduction of energy-saving electrical equipment, measures to improve the efficiency of heating and cooling in buildings and the development of "environmentally friendly" facilities that utilize renewable energy such as solar power generation. Is proceeding.
