The dataset provides water pollution intensities for Chemical Oxygen Demand (COD) and Total Suspended Solids (TSS); air pollution intensities for dust, smoke and sulphur dioxide (SO2). The units of measurement for value of output are kilograms per 1000/RMB Yuan. The pollution intensities are at the 2-,3-, and 4-digit ISIC level. These industrial pollution intensities have been produced by the "Economics of Industrial Pollution Control" team of DECRG in the World Bank using the China Environment Yearbooks for 1992, 1994, and 1996. These yearbooks were produced by China’s State Environmental Protection Administration (SEPA).
