In recent years, the surge in greenhouse gas emissions, environmental degradation, and climate change has emerged as a pivotal concern for environmental planners and policymakers. Given the predominant role of fossil fuels in carbon dioxide emissions, this study focuses on mitigating emissions, particularly in nations with robust fossil fuel economies. The primary objective of this research is to examine the impact of financial development and governance quality on carbon dioxide emissions within oil-exporting countries, utilizing the panel smooth transition regression model spanning the period 2000-2021. The findings substantiate the presence of a nonlinear relationship between financial development and carbon dioxide emissions. Initially, financial development exerts a positive and significant impact on emissions; however, beyond a certain threshold, this effect reverses, becoming negative. Regarding governance effectiveness, many oil-exporting nations wield substantial market influence due to their significant oil revenues. Notably, oil exporting-firms of these countries are predominantly state-owned or quasi-state firms. Their insulation from competitive threats, coupled with a lack of adherence to regulatory frameworks, has resulted in elevated carbon dioxide emissions under both governance regimes.

In recent decades, due to environmental pollution and the depletion of fossil fuel resources, the consumption of renewable energy sources has been increasing relative to non-renewable ones in many countries. The objective of this paper is to vigorously examine the impact of fossil and renewable energy consumption on economic growth and carbon dioxide (CO2) emissions, with a specific focus on oil-producing and non-oil-producing nations. In this research, 20 developing countries, including 10 oil-exporting nations and 10 non-oil-producing ones, were examined from 2000 to 2019 using panel data analysis, dynamic ordinary least squares, and Granger causality tests. The estimation results show that a 1 percent increase in renewable and non-renewable energy consumption, leads to an increase of 0.32 and 0.007 percent of GDP in oil-producing and 0.169 and 0.188 percent in non-oil-producing countries respectively. On the other hand, increased consumption of fossil fuels in oil-producing countries corresponds to an increase in carbon dioxide emissions, while the utilization of renewable energy sources in these countries leads to a decrease in CO2 emissions. Conversely, in non-oil-producing countries, an increase in the consumption of non-renewable energy sources is associated with elevated carbon dioxide emissions, while the incorporation of renewable energy sources leads to a reduction in CO2 emissions. The research results emphasize that endeavors to stimulate economic growth are accompanied by heightened carbon emissions and environmental degradation. Additionally, the findings highlight the significant role of renewable energy sources in controlling carbon dioxide emissions in both oil-rich and non-oil countries.Based on the results, a one percent increase in renewable and non-renewable energy consumption in both groups of countries leads to an increase in GDP. As an increase in fossil energy consumption in oil-producing countries rises the emission of carbon dioxide, and the use of renewable energy in this group of countries reduces the emission of carbon dioxide. In non-oil countries, the increase in the consumption of non-renewable energy rises the emission of carbon dioxide. Also, the consumption of renewable energy in this group of countries reduces the emission of carbon dioxide. The results of the present study show that in the studied countries, efforts to strengthen economic growth lead to increased carbon emissions and environmental degradation. The findings also indicate the positive effect of non-renewable energy sources on carbon dioxide emissions in both groups of oil-rich and non-oil countries and the positive effect of renewable sources on controlling carbon dioxide emissions.

Today, environmental issues, especially water and air pollution problems have become a major global concern. Air pollution, affects the health of living organisms and natural ecosystems. According to various studies, financial development in a country may attract Foreign Direct Investment (FDI) and higher degrees of research and development (R&D). This, in turn can, increase the environmental performance and thereby reduce environmental pollution. This investigation aims to examine the role of financial development and energy consumption in Iran during 1971-2007, in the framework of the environmental Kuznets curve, using ARDL approach. According to results further financial development in Iran lead to decrease of CO2 emissions. In addition, an increase in energy consumption in Iran is likely to increase CO2 emissions. Also, the results reject the Environmental Kuznets Curve hypothesis in Iran in the long-term.

This study investigates the Granger causality relationship between energy consumption, carbon emission and industrial value added, including labor and gross fixed capital formation in the model. We found that energy consumption is Granger cause of carbon dioxide emission and industrial value added. Also results of variance analysis model suggests that the long term effects of variables on their own swings gradually declines, and share of other variables increases.
