Abstract

Today, the issue of significant increases in polluting gases has become a major global challenge. This issue, along with industrial growth and development in developed and developing societies, has attracted more attention in order to prevent their destructive effects. The purpose of this article is to investigate the factors affecting the spread of pollution in the petrochemical sector. In order to test the relationship between the variables, a mild transfer regression model for the period 1399-1396 has been used. The statistical population of the present study is companies producing petrochemical products. The most important variables used in this study include per capita carbon dioxide emissions, product output, energy intensity, technology costs, and added value of petrochemical products. The results showed that there is a nonlinear relationship between the variables of production and pollution. In the estimated nonlinear model section, because the energy intensity variable has been selected as a variable, it was observed that with increasing the intensity of energy consumption from 5.12%, the effect of petrochemical production on the level of emissions is different and significant. The results obtained from the nonlinear model estimate show that the production of petrochemical products in companies producing petrochemical products at different levels of energy consumption has different effects on carbon dioxide emissions in the country. Accordingly, given that greenhouse gas pollution is one of the serious threats facing countries, and due to its nature, factories and companies producing petrochemical products should be required to reduce emissions through tax and incentive policies. In addition, more polluting industries and polluting products should be prevented from entering the production process through strict environmental laws and regulations, especially in the petrochemical sector.
