Mazda has defined its own standards, which are stricter than legally stipulated standards, for the emission of sulfur oxides (SOx), nitrogen oxides (NOx), particulate matter, finely ground waste, vapors, and volatile organic compounds (VOCs).

The introduction of scrubbers and low-load equipment, and implementation of stringent daily controls, have enabled us to meet all legally stipulated values.

When discharging wastewater to public waterworks, Mazda more than meets legally mandated emission quantities by maintaining voluntary standards stricter than the legal requirements, and by managing them on a daily basis. We also ensure wastewater cleanliness by properly treating water used for industrial processes, human hygiene, and other purposes.

Nearly all the water Mazda uses in production processes is water for industrial use. We do not use subsurface water, as this may cause ground subsidence. We also make effective use of water by collecting and storing rainwater for use in our Miyoshi Plant.
