Implementation of Environmental Audits
To confirm that environmental management systems, such those based on ISO 14001, EA21, and other standards, are functioning effectively, both internal audits and external audits are carried out annually at Mazda and all domestic and overseas Group companies that have obtained certification. The results of internal audits and external audits are reported to senior management, and any problems are swiftly and appropriately rectified.

Elimination of Sensory Pollution
Sensory pollution includes 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 the surrounding individuals. For this reason, the Company is systematically stepping up measures to alleviate the causes of such pollution as well as measures to improve noise insulation and odor removal.
Reduction of Vehicle Noise
Mazda has established its own noise standards for all vehicle models that are even stricter than the most recent legal requirements. Compliance with said standards is pursued to reduce road traffic noise from Mazda vehicles. The Company has also been actively developing technologies to reduce the three major types of vehicle noises: engine noise, air intake and exhaust system noise, and tire noise.
Example of Anti-Noise Measures (Mazda3)
Environmental Risk Management
Environmental Monitoring
Drills are conducted at individual production sites and offices to prepare to respond to accidents, incidents of environmental pollution, and other risks while regular environmental monitoring is performed in relation to air and water pollution and other environmental risks.
【Statistics from FY March 2025】
| Environmental Monitoring Category | Monitoring Target | Items Monitored | Monitoring Frequency |
|---|---|---|---|

Environmental Education Structure
Environment-Related Accident Prevention Activities
Oil Spill Prevention and Traffic Safety Campaign
Together with Mazda Logistics Co., Ltd. and several truckload transportation companies, Mazda Motor Corporation conducts an awareness-raising campaign aimed at improving traffic safety awareness and preventing oil spills on roads during vehicle delivery. In this campaign, which is held twice a year, awareness-raising leaflets are distributed to drivers of vehicles delivered to the Hiroshima Plant and the Hofu Plant. In doing so, the Company strives to improve such drivers' awareness of the environment and safety and create a system to ensure that employees can make a quick and appropriate response in the event of an accident. As part of its efforts to prevent oil spills from occurring, Mazda has established a record system* that consolidates databases on the maintenance status of each vehicle and information on past environmental defects and presents this information in a visual format. The system began operation in March 2021, and introduction of the system had been completed at all participating truckload transportation companies as of March 31, 2024. In FY March 2025, a series of briefings was held for the purpose of encouraging the adoption of this system at other transportation companies. Going forward, the Company will strive to utilize this system as an effective tool for preventing oil spills.
Awareness-raising leaflets being distributed
* The record system entails integrated management of various transportation vehicle information in the possession of truckload transportation companies to allow for alert messages to be sent to these companies as necessary. Information recorded by this system includes vehicle models, registration dates, travel distances, and dates of legally mandated and annual inspections and maintenance.
