Environmental Effects of Energy Intensive Industries in Iran

Environmental issues and emphasis on reduction of damage to environment is essential in policy formulation and developmental planning of countries. In each policy, identification of the source and type of pollutants due to improper use of energy is very important. In this study, we evaluated environmental aspects of Non-Metallic Minerals Industries and calculated the types of emissions resulting from energy consumption in each of these sectors. Results indicated that cement, lime and plaster had the highest share of carbon dioxide emissions and the highest share of social expenditures. In addition, the technical efficiency of these industries is calculated using SBM approach and efficient industry have been identified. However, the directional distance function has shown that these industries are not environmentally efficient friendly.
