Beijing: China has ordered a national census on the sources of pollution, as it seeks to bring down the high pollution level affecting several of its main cities. China is the world’s top carbon emitter. Beginning from December next year, the census will target industrial, agricultural and residential establishments and review the efficiency of centralised pollution control and treatment facilities.
A working group has been established under the Ministry of Environmental Protection to oversee the census.
The census is likely to be finished by 2018 and the results released in 2019. To ensure the accuracy of the census, in addition to employing traditional methods, remote sensing satellites and drones will be used to collect data.
