Assessment of the Environmental Performance in Energy Intensive Industries of Iran by Using Directional Distance Function Approach

In the recent years، environmental pollution، specially، air pollution، has become one of the main concerns of the international community and those are affected health of living organisms and natural ecosystems. In the recent past، environmental pollution has imposed significant human and financial costs on society. One of the most pollutant sectors is the industrial sector and between the polluting industries، the high energy consumer industries have imposed a significant part of environmental pollution. Hence، assessment of environmental performance in these industries is important. This paper using a directional distance function approach and (SBM) approach has evaluated the environmental performance and technical efficiency in the other non-metallic mineral products and production of basic metals industry، respectively. The results indicate that the other non-metallic mineral products industry Although technically more efficient، but have a lower environmental performance and Production industrial facilities، industrial Production cement، lime and plaster and asphalt manufacturing industry had the lowest environmental performance.
