University of Tehran Press Iranian Journal of Biosystem Engineering 2008-4803 46 3 2015 09 23 Energy and environmental life cycle assessment of canola production in Mazandaran province of Iran by applying two different approaches Energy and environmental life cycle assessment of canola production in Mazandaran province of Iran by applying two different approaches 265 274 56867 10.22059/ijbse.2015.56867 FA Seyed Hashem Mousavi Avval PhD Student, Department of Agricultural Machinery Engineering, Faculty of Agricultural Engineering and Technology, University of Tehran, Karaj, Iran Shahin Rafiee Professor, Department of Agricultural Machinery Engineering, Faculty of Agricultural Engineering and Technology, University of Tehran, Karaj, Iran Mohammad Sharifi Assistant Professor, Department of Agricultural Machinery Engineering, Faculty of Agricultural Engineering and Technology, University of Tehran, Karaj, Iran Soleiman Hoseinpour Assistant Professor, Department of Agricultural Machinery Engineering, Faculty of Agricultural Engineering and Technology, University of Tehran, Karaj, Iran Journal Article 2015 03 05 The objectives of this study at the first step are to analyze energy consumption and economical profitability in canola production in Mazandaran province of Iran and then to investigate environmental emissions of the production using life cycle assessment methodology. At the next step, the corresponding coefficients are applied to investigate environmental indices in canola production. Required data were obtained through interviews with farmers in the counties of Sari, Neka and Behshahr in the province. For investigating environmental emissions Impact 2002+ was applied and a single score was obtained. Then the coefficients were applied. The results revealed that there was no difference between the two methods and the results was completely same.
