Conservation of Air Environment

Conservation of Air Environment

Air pollutants discharged through our businesses include sulfur oxides (SOx), nitrogen oxides (NOx), and soot/dust emitted from boilers and furnaces as well as volatile organic compounds (VOCs) from crude oil or petroleum product storage tanks and tanker truck loading facilities. Thus, our refineries and complexes carry out operational management to ensure compliance with emission standards under laws and regulations as well as with emission limits prescribed by regional pollution prevention agreements.
