  Background and Objective:  Today environmental issues and avoid irregular greenhouse gas emission has become one of the most important concerns of each country. This study has been done with the aim of determining the amount of greenhouse gas emission in different industries and ranking these industries based on the most destructive greenhouse gas including carbon dioxide, carbon monoxide, Methane, Nitrous oxide, Nitrogen oxides, Sulfur dioxide and Sulfur trioxide. Method: In this study after identifying the most pollutant greenhouse gases based on the literature review and using the average of five recent year's data from the Iranian Statistics Center, the weight of each greenhouse gas were determined based on Shannon entropy and by using VIKOR technique and MATLAB software, the most pollutant sector was determined. Findings: Based on Shannon entropy, Co with the weight of 0.3 has the highest coefficient of importance among pollutant greenhouse gases. Based on VIKOR technique, transportation sector based on utility measure, Vikor measure and regret measure was determined as the most pollutant sector. Discussion and Conclusion:  Based on the result of study, transportation sector has played a major role in greenhouse gas emissions and identified as the most pollutant sector. So, attention to structural and cultural components associated to transportation field has become more important than the past. Using green transportation technologies, investing in public transportation and providing infrastructure for non- motorized vehicles can be introduced as suggestion for reducing pollution in this sector.                                                                                                       Manuscript profile

  According to erosion stones in Perspolis archeological zone, it was decided to study parametersaffecting this process. In this research, geographical map of the site and direction of seasonal andyearly winds were studied and samples of rain water were analyzed. Rain water samples fromdifferent locations of Marvdasht city in spring, autumn and winter was collected and tested for acidity.pH of the rain samples of Perspolis region varied between 5.97 and 6.58 during three seasons and allof them were acid rains, which could be one of the most important factors in erosion process of thisenvironment. It is predicted that pollutants emitted from Shiraz Petrochemical Company, Marvdashtcity industries and also exhaust from vehicles have moved toward the west and north-west zone bymentioned winds. So, these pollutants are conflicted to Rahmat mountains (Perspolis archeologicalzone is placed in hillside of Rahmat mountains) and soluted into rainfalls and finally washed with therain water (named acid rain) onto stones and environment of this zone.
