Compliance with Environmental Law and Risk Management

Eliminating Sensory Pollution

Sensory pollution comprises noise, vibration, and odors that have a sensory or psychological impact on people. Mazda recognizes that clearing legal regulations may not be enough to prevent noise, vibration, and odors from annoying neighborhood residents. For this reason, Mazda is systematically stepping up measures to alleviate the causes of such pollution, as well as measures to improve noise insulation and odor removal.

Specific Measures in Environmental Risk Management

Environmental Monitoring

  • Regular training is conducted at each plant and office to prepare for response in the event of accidents that adversely affect the natural environment.
