Estimate greenhouse gas emission, classify environmental protection and propose solutions for greening some industries in Long An province

Abstract

In order to improve the efficiency of environmental protection and make favorable conditions for environmental management and supervision in industrial zones in Long An province, the study of calculating greenhouse gas emission and developing a set of criteria for classifying environmental protection for industries being operated in this area is necessary. Greenhouse gas emission of three industries, including chemial protection plant, metal, paper production were  calculated and the results were  822,63 tons CO₂eq/year; 2.067,18 tons CO₂eq/year; 48.965,78 tons CO₂eq/year respectively. Using multi-criteria approach to screen the criteria for classification, and obtaining the official set of criteria including 24 criteria in four topics: economic potential (2 criteria); Environmental emissions (12 criteria); resource consumption (3 criteria); management response (7 criteria). Applying these criteria for classifying three industries, the results shown that the environmental protection in both chemial protection plant and paper production are average and that is quite good in metal production. Thereby, the authors proposed some solutions to improve the efficiency of environmental protection for production facilities operating in three research industries, including three groups of solutions: Reducing emissions to the environment; Saving resources and Promoting environmental protection management.
