“…The first measurement is to estimate the pollution intensity of product, that is calculating the emissions released from per unit of production. The second method is to measures the pollution content by means of pollution abatement and control expenditures (PACE), which captures the producer's cost burden of pollution regulation (Akbostanci et al, 2007). Low (1992) calculated relative abatement costs for US industries, and according to Low's calculation, Busse (2004) classified the dirty industries, which is abatement costs of at least 1.8% of total costs, including: industrial chemicals industry, paper and pulp industry, non-metallic minerals industry, iron and steels industry, and non-ferrous metals industry.…”
