Determinant factors energy efficiency and emission of pollutants Co2 & So2 in Iran's agricultural sector

Large amounts of environmental pollutants that occur in nature mean a serious problem. Improving productivity as one of the most important sources of economic growth means using efficient production for all resources including labor, capital and energy. The main purpose of this study is to investigate the relationship between energy efficiency and CO2 and SO2 emissions as a criterion for environmental pollution and consumption of energy carriers and to determine the most effective factor on energy efficiency in Iran's agricultural sector. In this study, to achieve the objectives of the research, annual data on the consumption of energy carriers and environmental pollutants during the period 1988–2016 for the agricultural sector of Iran using Eviews10 software and vector regression model have been used. The results show that the decrease in energy efficiency in the agricultural sector by 1.037 and the increase in energy consumption by 1771.2 and with one difference, The energy efficiency of the agricultural sector has increased by 0.53 which indicates the optimal and efficient use of energy. Labor has been positive with two interruptions, and capital is positive in the first interruption, which is the most important factor influencing the energy efficiency of the agricultural sector and shows an increase in energy efficiency of the agricultural sector. The highest CO2 emissions are related to electricity prices. Given the positive relationship between electricity prices and emissions, it can be said that the increase in electricity prices in the agricultural sector (26,714.39) should be partially replaced by fossil fuels, thus increasing pollution and reducing energy efficiency.
