Reduction of Air Pollutants

Due to the use of oil cokes in the casting process of the engine business in the Higashichita Plant we generate sulfur oxides (SOx) and nitrogen oxides (NOx), which are considered to be causes of acid rain.

SOx emissions into the atmosphere substantially declined to less than 1% compared with FY2001 levels as a result of introducing a system to recover these gases, improvements in our manufacturing facilities, and changes in the fuels we use.
On the other hand, total NOx emissions tended to increase due to the greater use of city gas for a co-generation system that we are actively introducing to reduce CO2 emissions.
