Since the energy consumption has increased globally, many countries are searching to conduct a procedure for balancing between the energy consumption and its environmental impact. Therefore, there has been plenty of research to discover new strategies for decreasing carbon emission and highlighting the influential factors. This study has analyzed the carbon emission measures in several different sectors using the input-output approach. Also, the study has measured the effect of carbon emission on the total intensity by calculating the structural intensity and domestic energy consumption. The data is extracted from social matrix of Iran`s economy in 2011 and 2014. The findings indicate that the gas emission rate differs in different sectors and as a result the emission intensity is also different. In general, the emission intensity from 2014 has increased compared to 2011 though the emission intensity in agriculture sector has surged. Also, the total national AEI has increased as a result of structural effect and final demand for it. In other words, structural effect and final demand has influenced in the surge of carbon emission.
