'To prevent air pollution, when installing or updating equipment that uses fuel, we opt for fuels

that minimize generation of air pollutants (such as sulfur oxide, nitrogen oxide and soot), and have

banned the use of heavy oil in principle.

Furthermore, we have designated ozone-depleting substances and persistent organic pollutants cited in the Stockholm Convention on Persistent Organic Pollutants as banned substances'.
