Initiatives
Initiatives of Environmental Management Systems
Establishment of Environmental Management Systems
Mazda is promoting the establishment of environmental management systems (EMS) across its entire supply chain and in all Group companies. The purpose of the EMS is to carry out more environmentally conscious business activities in a more effective manner, based on ISO 14001 and other standards.
【Statistics from FY March 2024】
- Acquisition of ISO 14001 certification by Mazda and 14 of 15 Group manufacturing companies in Japan and overseas
- Promotion of receipt of certification under EcoAction 21 (EA21),* an EMS, by domestic automobile sales companies; completion of certification by 15 sales companies and at Mazda Chuhan Co., Ltd.; promotion of certification at owner-managed dealerships resulting in acquisition of certification at a total of 119 dealerships comprised of 24 dealerships for the Mazda/Mazda Enfini sales channel, 94 dealerships for the Mazda Autozam sales channel, and Mazda Chuhan (as of the end of March, 2024)
* EA21 is a simplified EMS established by the Ministry of the Environment, for application at companies of various scales, such as small to medium-sized companies.

Promotion of Green Purchasing
With the aim of reducing environmental impact throughout its entire supply chain, Mazda established the Mazda Green Purchasing Guidelines and takes action in accordance with these guidelines. These guidelines require all of its suppliers worldwide to undertake measures to reduce their impacts on the environment at all stages, spanning from product development to manufacturing and delivery. The guidelines also make it clear that Mazda will give preference in purchasing to suppliers who implement such environmental measures. Moreover, under the guidelines, Mazda asks suppliers to formulate and enact road maps for reducing their CO₂ emissions. The Company has received such CO₂ emissions reduction road maps from local and major suppliers, and collaborative efforts toward carbon neutrality are underway.
Mazda also requires suppliers of parts, materials, and industrial equipment and tools to obtain and maintain ISO 14001 certification and to reduce the amount of greenhouse gas emissions generated through their corporate activities. In addition, the Company promotes environmental activities in collaboration with its suppliers by providing them with information and other assistance. Presently, all major suppliers involved in Mazda vehicle development and manufacturing have acquired ISO 14001 certification.
【Statistics from FY March 2024】
- Rate of 100% for maintenance of ISO 14001 certification among 500 new and continuing major suppliers around the world (as of March 31, 2024)
- Requests for EMS development in accordance with the Mazda Green Purchasing Guidelines issued to secondary suppliers and subcontractors through primary suppliers
Status of Implementation of Environmental Audits
To confirm that EMS, such as ISO 14001 and EA21, are functioning effectively, both internal audits and external audits are carried out annually at Mazda and all Group companies, both in Japan and overseas, 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.

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, 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 which are even stricter than the most recent legal requirements. In compliance with the above in-house standards, the Company has been working to reduce the road traffic noise of all the passenger vehicles and commercial vehicles it produces. The Company has also been actively addressing the development of technologies to reduce the three major vehicle noises: engine noise, air intake and exhaust system noise, and tire noise.

Environmental Education Structure


Routine Environmental Activities
Employees are working on environmentally friendly initiatives through their individual daily tasks.
Reduction of Paper Use
Mazda makes ongoing efforts to considerably reduce the amount of paper used for office work through the digitization of documents, ledger sheets, and other forms as well as through the use of projectors and monitors at meetings. In addition, the Company is promoting recycling through exhaustive waste sorting.
Energy Use Reduction
Through regular initiatives, including purchasing of low-power consumption office equipment and furniture and turning off lights and computers when they are not in use, Mazda is working to reduce energy use. In addition, the Company encourages offices and factories to turn off half of the lights during lunch breaks as a continuous measure. Furthermore, the Company implements a “Cool Biz” program during the summer season every year, setting internal room temperatures at 28°C (82.4°F) on a standard basis. During the winter season when electricity consumption is particularly high, the Company implements a “Warm Biz” program, setting internal room temperatures at 20°C (68°F) on a standard basis.
Eco-Walk Commuting Program
In order to raise employees’ environmental consciousness and encourage them to take better care of their health, employees who walk two kilometers or more as part of their daily commute to work are rewarded with an addition of 1,500 yen per month to their commuting allowance.
Mazda Light-Down Campaign
To raise environmental awareness, Mazda and domestic Group companies participate in the Mazda Light-Down Campaign, in which they turn off their signboards and indoor lighting.
【Statistics from FY March 2024】
- Lighting shut off for two hours from 20:00 to 22:00 on June 21 (summer solstice) and July 7 (Tanabata star festival in Japan)
- Reduction of 12 MWh in electricity use and approximately five tons in CO₂ emission
Environment-Related Accident Prevention Activities
Campaign for Oil Spill Prevention and Traffic Safety
Together with Mazda Logistics Co., Ltd. and several truckload transportation companies, Mazda Motor Corporation conducts an awareness-raising campaign to prevent oil spills on roads during vehicle delivery and improve traffic safety awareness. In this campaign, which is held twice a year, awareness-raising leaflets are distributed to drivers of delivery trucks 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. Going forward, the Company will strive to utilize this system as an effective tool for preventing oil spills.


Awareness raising fliers 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 date of legally mandated and annual inspections and maintenance.
