The Environmental Effects of Households Consumption with Respect to Incrementin Gas Delivery: An Input-Output Analysis

In investigating economic dimensions of energy consumption, greenhouse gas emission and its environmental effects have taken on considerable importance in recent decades. Among all, households are considered one of the highest energy consumers and greenhouse gas emitters. With respect to the lower level of carbon in natural gas, the use of this gas leads to less emission,compared to other energy conduits. This study investigates changes in emission of different kinds of pollutants resulting from energy and other consumptions of households in 2001 and 2012. To this end, an Input-Output analysis is employed. The results of the research demonstrate that direct and indirect consumption of different kinds of energy conduits in 2012 increased compared with 2001, whichin turn caused an increment in the emissions of different kinds ofpollutants originated from direct and indirect energy consumption of households in 2012 compared with 2001. However, increments in gas delivery have leads the energy consumed by households,as well as the energy used for different household goods and services,to gradually be replaced by cleaner types
