  • Detail

China plans to issue the first national standard to control the emission of air pollutants from ships. The Ministry of Environmental Protection announced on the 8th that the "limits and measurement methods of exhaust pollutants from ship engines (China's first and second stages)" will be open to the whole society for comments for the second time from now on. If the new standard is officially promulgated and implemented, it will be the first time for China to issue the national standard for the emission control of air pollutants from ships until the tension fracture

it is understood that China has formulated corresponding standards for the pollution control of water and solid waste discharged from ships, but the air pollutant emission control standards for ships have remained blank for a long time. At present, the emission control of air pollutants from ships in the world is mainly controlled by marine engines. Through environmental management methods such as type approval, production consistency inspection and in-service compliance inspection, the emission control of air pollutants from ships is realized. The standard also adopts this general management idea, and the test method adopted is consistent with the existing international regulations and standards

in addition, the Ministry of environmental protection is formulating the emission standard of pollutants for the shipbuilding industry, focusing on controlling the emission of VOCs and other air pollutants during shipbuilding

xiongyuehui, director of the Department of science and technology standards of the Ministry of environmental protection, said that China is a country with rich inland river shipping resources. By the end of 2013, China had 172600 water transport ships with a net payload of 244 million tons. Among the top ten ports in the world, China holds eight seats, and its throughput accounts for about a quarter of the world. The problem of environmental pollution caused by ship transportation has become increasingly prominent. For outdoor lines

it is estimated that in 2013, the national ship sulfur dioxide emissions accounted for about 8.4% of the total national emissions, and the nitrogen oxide emissions accounted for 11.3%. Port cities are the most affected by ship pollution, followed by cities along rivers

in view of the urgent situation of air pollution prevention and control in China's ports and ships, in order to implement the requirements of the environmental protection law and the air pollution prevention and control law, the Ministry of environmental protection timely launched the formulation of emission standards for ship engines. This standard was published to the public in July 2014, and 156 feedback comments were received. Based on this, the standard preparation team modified and improved the content of the standard, forming a second exposure draft

compared with the first exposure draft, the second exposure draft has adjusted the provisions on the use of fuel oil by ships in the standard, and widened the types and scope of fuel oil used by ships; Increased the durability requirements of marine engines for entertainment; Added the requirements for exemption of ship engines; The durability life requirements are increased.

Xiong Yuehui said that after the new standard takes effect, the emission level of exhaust pollutants from ships and aircraft will be further reduced. In addition, the regulations on the use of marine fuel in the standard will obtain significant environmental benefits. It is estimated that only transport ships (excluding fishing boats) across the country will reduce sulfur dioxide emissions by about 950000 tons and particulate emissions by about 110000 tons per year by improving fuel quality

Xiong Yuehui said that China's coastal, riverside and port cities will be the main beneficiaries of the above emission reduction benefits, and the implementation of the new standards is of great significance to improve the ambient air quality of these places and cities
