MAZDA:CO2 reduction | Initiatives in Production

Mazda is working to promote efficient utilization of energy and reduce the volume of CO₂ emitted in all aspects of our production and distribution operations.

"Mazda Green Plan 2010" aims to cut by FY2010 the total CO₂ emissions generated by our four principal domestic facilities*1 (including R&D and other administrative departments), despite increased production levels, by at least 20% from the FY1990 level.

In FY2008, energy use and CO₂ emissions both dropped due to a cutback in production caused by the sudden sales downturn.

We conducted wide-ranging activities to drastically reduce operational waste at our plants. For example, we made efforts to raise total equipment efficiency through concentration of production and efforts to eliminate waste due to unnecessary or idle equipment. We also analyzed production processes to expose causes of operational loss.

As a result, our total CO₂ emissions volume from our four principal domestic plants in FY2008 was 609,000 tons, or 40.2% less than the FY1990 level, which equates to 33.4 tons per ¥100 million in sales revenue (a reduction of 26.9%).

In the future, by continuing to maintain and strengthen our flexible production system, Mazda will further improve its overall energy efficiency and achieve even lower CO₂ emissions.

In July 2009, a new passenger car plant at AutoAlliance (Thailand) (AAT), Mazda's Thai manufacturing subsidiary, was completed. It is AAT's second plant and employs flexible manufacturing technology that enables multiple car models to be produced on a single production line. The production line is environmentally friendly because it reduces superfluous processes to achieve improved efficiency. In addition, Mazda's Three Layer Wet Paint System, which reduces VOC emissions by about 45% and CO₂ emissions by about 15%, was installed in the paint shop at AAT in 2008.

In addition to introducing this advanced equipment, AAT is making its workplace more environmentally friendly through measures such as reusing work gloves and meticulously scheduling operation times for air compressors.
