Determining the Amount of Carbon Dioxide Emission from Primary Energy Consumption in Different Production Sectors of Iran: A multi-factor Energy Input-output Analysis

This study investigates the impact of final demand change on primary energy consumption, renewable energy consumption, CO2 emissions, and economic growth. For this purpose, the multi-factor energy input-output method proposed by Guevara and Domingos (2017) has been adopted, and an input-Output table for the year 2016 has been used. The results show that among energy products, electricity has the highest primary energy consumption coefficient. Although the rate of renewable energy consumption in this product is higher than other products, due to the small share of renewable energy consumption in primary energy consumption, electricity has the highest rate of CO2 emission. Also, the efficiency of primary energy conversion to secondary energy is 24% with the lowest efficiency among energy products. Among non-energy products, non-metallic mineral products and transportation services have the highest primary energy consumption coefficient and CO2 emission. The results of units’ emission production growth of the sectors related to non-energy products show that leather products had the least CO2 emissions per production growth unit. In contrast, transportation services had the highest emissions per production growth unit.
