The aim of this study was to estimate the nonlinear effect of oil, gas, electricity, and coal energy consumption on carbon dioxide emissions in ten energy-intensive countries (Iran, South Korea, Japan, Germany-Russia-USA-India-Canada-Brazil and China) in the world. Statistics and information used to estimate the nonlinear autoregressive panel model with distributed intervals (PANEL NARDL) have been extracted from the database of the World Bank and the World Energy Organization for the period 1985-2019. The results show that increased consumption of gas, electricity, coal, and oil leads to increased carbon dioxide emissions, while a decrease in their consumption reduces carbon dioxide emissions in the long run. Also, the nonlinear relationship between the per capita of consumption of these four types of energy and the emission of carbon dioxide in high-consumption countries was confirmed by the parent test in the long run. Therefore, reducing the use of fossil fuels and shifting the focus to clean and renewable energy consumption is proposed for the five selected countries, especially Iran, and economic policymakers should prioritize environmental protection by enacting applicable laws. In this way, the creation and development of intelligent infrastructure for the carbon economy and industry are essential.

During the last decades, global warming and climate change has created much concern across the world. These concerns coincided with the aim of achieving higher economic growth, has become Environmental risks arising from economic activity to a controversial issue. The main objective of this study is to investigate the long run effects of economic and financial developments on environmental pollution in selected Opec countries over the period 1973-2007. The results show that financial development indicators have significantly negative impact on CO2 emissions. Also, the results show that the relationship between economic development and CO2 emissions follow a N shaped relationship. Hence, the recommended policy is more financial development in order to improve the quality of the environment.

Most studies suggest a form of inverted U relationship between environmental quality and economic growth, entitled as "the environmental Kuzne's curve (EKC)"
Given the importance of maintaining environmental quality along with economic growth, this study studies the level of water pollution and economic growth both in developing and developed countries during 2001-1980. Based on theoretical foundations of environmental EKC curve, as in addition to the income variable, the population variable, is also considered as an exogenous variable and the integration method is used for estimating the model. The results indicates that the economic conditions prevailing in both groups of countries are consistent with the EKC. Curve and it this curve. The turning point in developed countries is at 10,622 dollars based on statistical findings, most of the studied countries in this group have crossed the turning point. But as for developing countries, the turning point in this curve is estimated at approximately 901 dollars of national per capita income. Statistical analysis of existing data showed that many countries at this group still have not reached the turning point of the EKC curve and are far from it. Using the results, it seems necessary for the developing countries to adopt more cautious policies to grow and develop their economies, in order to promote the growth of national per capita income, as well as policies to improve quality of water resources, or at least prevent their contamination.

Countries efforts to achieve rapid economic growth and lack of adequate attention to environmental issues in recent years have caused serious damage to the countries environment. Hence, examining factors affecting the quality of environment is more important. This article aims to investigate the Impact of economic growth, energy consumption and openness on Environment pollution in Iran from 1967-2007. This paper uses some econometric techniques, including Johansson approach and DOLS model to explore the influence of economic growth, energy consumption and openness on Environment quality. The result of the analysis reveals a positive sign for the coefficients of economic growth, energy consumption and openness. Also the findings does not support the existence of an inverted U-shaped relationship between economic growth and invironmental pollution.
