Making Environmentally Friendly Vehicles

Management and Reduction of Substances with Environmental Impact

Mazda is engaged in a range of initiatives to eliminate or reduce chemical substances that damage the environment.


Collection and Management of Automotive Parts Materials

Mazda is working across its entire supply chain to reduce the use of environmentally hazardous materials such as lead, mercury, hexavalent chromium and cadmium. Using the standardized IMDS*1, international system, the Company gathers information on the materials from suppliers.

  • *1International Material Data System.
How IMDS Works

  • To ensure that suppliers enter IMDS data appropriately, the Company publishes and distributes guidelines each year.
  • The data gathered through IMDS is used to calculate the Company's vehicle recycling rate and to comply with various regulatory regimes for chemical materials, such as REACH in Europe.

VOC Reductions: VOCs in Vehicle Cabins

To maintain a comfortable cabin environment, Mazda is committed to reducing VOCs*2 such as formaldehyde, toluene and xylene, which have been implicated as possible causes of sick building syndrome.

  • In 1999 Mazda developed a deodorizing filter with the capacity to remove aldehydes (adopted as either standard or optional in core vehicle models).
  • In new models, starting with the Demio/Mazda2 launched in 2007, Mazda reduced VOCs in the main materials used in the cabin, such as plastics, paints, and adhesives, thereby conforming with the indoor aerial concentration guidelines established by Japan's Ministry of Health, Labour and Welfare.
  • The new Axela/Mazda3 launched in 2013 also conforms to the indoor aerial concentration guidelines of Japan's Ministry of Health, Labor and Welfare.
  • *2Volatile Organic Compounds.

VOC Reductions: Body-Painting Lines

In FY March 2014, Mazda made steady progress toward achieving the target of reducing VOC emissions from vehicle body paint in body-painting lines to 24.5 g/m² or less.
The target was achieved by reducing VOC emissions in body painting lines to 24.4 g/m², as a result of various measures. Such measures include the Three Layer Wet Paint System introduced in all plants in Japan and major plants overseas, the Aqua-Tech Paint System (introduced in Ujina Plant No. 1) that delivers world-leading environmental performance, and improved efficiency in thinner recovery in cleaning operations.


Reducing Use of "CFC Alternative" Greenhouse Gases

Mazda is working to reduce the amount of CFC alternatives, which constitute greenhouse gases, used as car air-conditioner refrigerants. The Company is also proceeding with product development and adoption of air conditioners that use novel refrigerants in place of CFC alternatives.
