This study examined the impacts of economic policy uncertainty and oil price on carbon dioxide emissions as a criterion of environmental quality in seven OPEC member countries from 1990 until 2019. According to the theoretical framework, economic policy uncertainty can directly or indirectly affect the quality of the environment, such as through direct policy adjustment, consumption, and investment channels. In this regard, with the help of panel data, the experimental models of this study were estimated and evaluated by the Fully-modified Ordinary Least Squares (FMOLS) method. The results indicate that the economic policy uncertainty and the oil price variables are statistically significant in both models, and their coefficient is positive. In other words, higher policy-related economic uncertainty and oil price over this period has led to higher carbon dioxide emissions and, thus, lower environmental quality in OPEC member countries. Ultimately, the estimates in the second model confirm an inverse U-shaped relationship between economic growth and the quality of the environment of these countries in the mentioned period, based on the Environmental Kuznets Curve (EKC) hypothesis.

The main purpose of this study was to investigate the role of trade by export and import of intermediate and final goods on environmental degradation, and carbon dioxide emission, in the form of the Environmental Kuznets Curve (EKC). For this purpose, a panel data set of OECD, and non-OECD countries from 1998 to 2018 was used. According to the results, the EKC was established in all samples. In addition, while with a sample of OECD countries, trade has a beneficial or inverse effect on carbon dioxide emissions; with a sample of non-OECD countries, and that of all countries, a non-beneficial or direct effect from trade on carbon dioxide emissions prevails. Also, an important conclusion is that imports, regardless of the type of goods, had a more destructive effect on the environment than exports in all samples. Therefore, theories supporting beneficial effects of exports, e.g. improving technology, or destructive effects of imports through energy-intensive products, are better explanations of the issue than theories of destructive consumption of energy resulting from exports, or beneficial effects of imports for the environment

Industrialization leads to emission of carbon dioxide from extensive use of fossil fuels. This study investigates the dynamic relationship between economic growth, trade freedom, coal consumption and carbon dioxide emission in Iran. An autoregressive distributed lag (ARDL) model is designed to study the short term and long term relationship. After evaluating the model for unit root test, a logistic regression analysis was run on the basic of 1986-2012 data for the economy of Iran. Our findings indicate the existence of a significant correlation between economic growth, trade freedom and coal consumption with carbon dioxide emission. Thus the presence of Environmental Kuznets Curve are confirmed both in the short-run and long-run. Panning for coal consumption reduction can be emphasized as a policy tool for emission reduction.

The greenhouse gas emissions as a result of human activities is considered the main factor in global warming. This subject is of greater importance in OPEC countries because of the dependency of OPEC economies on fossil fuels and their economic vulnerability in relation with climate changes conventions and the Kyoto Protocol. In this study, besides analyzing the extent of compliance with EKC in the OPEC and OECD countries, the most important factors influencing CO2 emission will be examined and also the policy implications of KEC for Iran will be studied. The findings indicate that firstly, the inverse U shaped Environmental Kuznets Curve is not confirmed for all the studied countries, including Iran. Secondly, manufacturing value added to GDP (as an industrial development index), trade to GDP (as the openness index), and energy consumption to GDP (the energy intensity index) are found to be the main macroeconomic determinants.

This research investigates the existence and direction of Granger causality between economic growth, energy consumption, and carbon emissions in Iran. A multivariate model including economic growth, energy consumption, carbon emissions, capital stock, labor force, and urban population is used to determine eventual causality between variables according to Toda-Yamamoto Approach. Results indicate that there is a bi-directional causality relationship between gross domestic product and CO2 emissions. Also, there is a uni-direction causality relationship from energy consumption to CO2 emissions. Finally, the results maintain that the EKC hypothesis for GDP and CO2 emissions is relevant in the period of study.
