An Investigation of Energy Consumption, Economic Growth and Co2 Emission in the Iranian Economic Sectors

Although the trend of increase in energy consumption has made possible fast economic growth of industrial modern society, but because of combustion pollutants emission and increase in density of carbon dioxide in atmosphere has made irreversible changes in the world. Not only this trend is destroying finite and nonrenewable energies, but also it is releasing numerous of pollutants into the receptive environment (air, water, and soil).
In this article, existence of caus ality relation between energy carrier's consumption with economic growth and carbon dioxide gas emission in sectors of economy (residential, general and commercial, industry, agriculture, and transportation) in period of 1376 to 1391 using causality Toda and Yamamoto has been studied. In order to identify consumption of which energy carrier excites economic growth and carbon dioxide gas emission in each sector or economic policy in which energy carrier for a sector is suitable for that sector without reducing economic growth rate.
In the agriculture sector, results show a unidirectional causality relation of energy carrier consumption to economic growth. In transportation, residential, general and economic sectors existence of bidirectional causality relation of economic growth variable and carbon dioxide gas emission with energy carriers has been verified. In industry sector, a unidirectional causality relation of economic growth to gas, electricity to economic growth and bidirectional causality relation of coal exist. Also, unidirectional causality relation of carbon dioxide emission to oil and bidirectional causality relation carbon dioxide gas emission to other variables except oil exist.
