To preserve air and water quality, Mazda has specified voluntary emission standards stricter than the legal requirements and is ensuring appropriately low emissions of pollutants.
Mazda has defined its own standards, which are stricter than legally stipulated standards, for the emission of sulfur oxides (SOx), nitrogen oxides (NOx), dust and soot, fine particles, vapors, and volatile organic compounds (VOCs), and is continuing efforts to reduce such emissions.
In addition, Mazda is shifting the use of fuel oil to that of city gas and makes other efforts to actively adopt materials that reduce the environmental burden.
When discharging wastewater to public waterworks, Mazda maintains voluntary standards stricter than the legal requirements, and manages discharge daily.
The Company also ensures wastewater cleanliness by properly treating water used for industrial processes, human hygiene, and other purposes.
With the exception of its Miyoshi Plant, nearly all the water Mazda uses in production processes at the plants and offices in Japan is water for industrial use. The Company does not use subsurface water, as this may cause ground subsidence. Mazda also makes effective use of water by collecting and storing rainwater for use in the Miyoshi Plant.
