China's largest coal shipping port, has adopted a new regulation to
prevent air pollution from ships, that came into effect this December.
The rule states ships that emit "visible black smoke" for three minutes
or longer will be punished.
In addition, incinerators are banned in ships off the waters of Qinhuangdao, the regulation said.
Priority will be given to the ships powered by fuel oil with sulphur
content below 0.1 per cent m/m in entry, load and unload, and departure
of the port, Xinhua reported.
"As the port and the urban area are connected seamlessly, ship emissions
have become one of the important sources of air pollution in the city
of Qinhuangdao," said Qinhuangdao Ecology and Environment Bureau deputy
director Wang Xinzhi.
The number of merchant ships in and out of Qinhuangdao has reached
14,000 so far this year. It is estimated that the 24-hour emission of
PM2.5 pollutants by a medium-sized containership is equivalent to the
daily emission of 500,000 heavy trucks.
