The Effect of population growth, human capital and petroleum products on environmental pollution in Iran

Survey environmental pollution is an important issue of environmental economics. Environmental pollution is the most important problem facing humanity in the present age. With increasing population, the rate of changes in the environment intensifies especially if the population does not have knowledge of how to protect the environment, this problem increases. The role of human resources in the production process and therefore the quality of the environment from the perspective of economic theory, have been significant changes over time. The aim of this study was to investigate the effect of petroleum products, human capital and the population on environmental pollution in the Iranian economy during the 1357 to 1393. In this study, Environmental pollution model is estimated by using an Auto Regressive Distributed Lag Model (ARDL), this model, CO2 emissions are considered as indicators of environmental pollution. The findings of the long-term model show Banerjee, Dorado and Master t-test, for models was -3.35 and long-term relationship between variables was confirmed. Including error correction model coefficients showed that 41.53 percent of imbalance is a period of adjustment in the next period. The model tries to adjust its medium speed. The results show a positive relationship between oil consumption, population and national income on environmental pollution. The results showed a negative relationship between human capital and environmental pollution as well. Therefore, it is suggested by reducing the consumption of petroleum products subsidies and to encourage consumers to use clean energy reduce the amount of environmental pollution.
