Environmental Management

Mazda is establishing an environmental management system throughout its value chain, including Group companies, suppliers, dealerships, and others.

Establishing 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.

Progress Status

  • ■ 13 Mazda and Group manufacturing companies in Japan and overseas have now acquired ISO 14001 certification.
  • ■ Mazda is progressively certifying all dealerships in Japan under EcoAction 21 (EA21)*1, an environmental management system (As of March 2015, 33 dealerships of the Mazda/ Mazda Enfini sales channel, 60 dealerships of the Mazda Autozam sales channel, and Mazda Chuhan, a used car sales company, have been certified).
  • ■ Mazda has completed introduction of an exclusive Mazda EMS to three Mazda Group vehicle parts companies in Japan.

*1 Simplified EMS established by the Ministry of the Environment, for application at companies of various scales, such as small-to-medium sized companies.

Promoting Green Purchasing

With the aim of reducing the environmental burden throughout its entire supply chain, Mazda engages in operation activities in compliance with the “Mazda Green Purchasing Guidelines” (revised in September 2014).
These guidelines require all of its suppliers worldwide to undertake measures to reduce their burden on the environment, at all stages 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.
Mazda also requires its 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.
Currently, all major suppliers involved in Mazda vehicle development and manufacturing have obtained ISO 14001 certification.

Status of Establishment of Environmental Management Systems (EMS) at Suppliers

  • ■ All major suppliers with which the Company has ongoing business relationships (around 400 companies), including new suppliers, have maintained certification as of the end of March 2015.
  • ■ Under the Mazda Green Purchasing Guidelines, Mazda requires, through primary suppliers, secondary suppliers to establish EMS.

Status of Implementation of Environmental Audits

To confirm that environmental management systems, such as ISO 14001 and EcoAction 21, are operating effectively, internal audit and environmental management system audit (EMS audit) are carried out annually of all Group companies, both in Japan and overseas, that have obtained certification, including the Hiroshima district and Hofu Plant. The FY March 2015 EMS audit revealed no serious compliance issues.
The results of the internal audit and EMS audits were reported to senior management. They were also shared with the related members at all certified areas, and any problems were swiftly 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, 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 Initiatives in Environmental Risk Management
