Introduction: Considering that Iran is one of the ten countries with the most pollution, research in this field is necessary. The goal of countries is high economic growth along with the non-emission of pollution. Environmental destruction and climate change are problems of all countries. Some people believe that economic growth leads to the destruction of the environment, and some others do not accept this theory. Sustainable development means that today's generation must meet its own needs without compromising the next generation. Today, countries are trying to achieve sustainable development by minimizing environmental destruction in addition to economic growth. To achieve this goal, international treaties have been concluded between the countries of the world. Many environmental protection organizations were established. One of the long debates among economists is energy consumption. On the one hand, due to economic growth and production of goods, energy consumption is needed, and on the other hand, the pollution caused by the consumption of this energy fuels environmental and non-climate pollution in countries. Because Iran is a country that sells oil and natural gas, it is a country that has a relative advantage in the field of fossil energy. Considering that Iran has a relative advantage in energy consumption, research in this field becomes necessary. Energy consumption can lead to more pollution.Materials and methods: For the first time, this research investigates the factors affecting energy consumption and pollution emission in Iran using the Markov switching method, fully adjusted ordinary least squares and dynamic ordinary least squares and Johansen's method, for the period of 1994-2021. examines In most of the studies conducted on the relationship between energy consumption and major macroeconomic variables, the influence of factors affecting energy consumption, especially factors affecting energy consumption and pollution emission in Iran, has not been paid attention to. For the first time, this research examines the experimental test of the environmental Kuznets curve with three dynamic time series methods, including fully adjusted ordinary least squares and dynamic ordinary least squares, with three optimal intervals and Johansen's method.Results: According to the results of this research, with all three dynamic time series methods, the Kuznets curve was confirmed for Iran, and this country is located in the downward part of the Kuznets curve, which means that economic growth initially leads to pollution, but later it causes pollution. Pollution is reduced. Energy consumption has had a positive and significant effect on carbon dioxide emissions. According to the research results, gross domestic product, energy consumption, foreign direct investment have a positive and significant effect on carbon dioxide emissions. Trade has a negative and significant effect on carbon dioxide emissions. The LR test showed that the model is nonlinear and the Markov switching method was used to estimate the model. The results obtained using Markov switching MS-ARMA(3,1,0) method show a positive and significant relationship between trade, GDP and energy consumption with a break on energy consumption. Due to the composition effect of Iran in energy-intensive industries, it has found a relative advantage and trade has a positive and significant effect on consumption.Keywords: FMOLS، DOLS، Kuznets Curve, Johansen

Introduction: Fossil fuel consumption has warmed the earth by releasing greenhouse gases. Abnormal climate changes, rising sea levels, melting glaciers and other climate phenomena have attracted global attention. Greenhouse gas emissions are considered as the main cause of climate change and global warming. The largest percentage of greenhouse gases is carbon dioxide gas. The spread of pollution is one of the most important problems of countries It is one of the problems of the present century. Iran is among the ten countries with the highest carbon dioxide emissions in the world, and measures have been taken to reduce carbon dioxide emissions in this country, which have not led to a reduction in carbon dioxide emissions in this country.Materials and Methods: The purpose of this research is to investigate energy consumption, carbon dioxide emissions and economic growth using the directional non-cyclical graph approach for the period of 1990-2018 for the country of Iran. The data was obtained annually from the World Bank. Pearson's correlation test and Granger's causality test were investigated for variables of economic growth, capital, open trade, carbon dioxide emissions and energy consumption. For the first time, this research examines the causal relationship between energy consumption, carbon dioxide emissions and economic growth with the approach of a directed non-cyclic diagram.Results: According to the results of this research, there is a significant correlation in the variables of carbon dioxide emission, open trade, energy consumption, capital formation and GDP. The highest correlation coefficient belongs to GDP and carbon dioxide emissions and the lowest correlation coefficient is related to gross domestic production and open trade. According to the results of the Granger causality test, causality from GDP to carbon dioxide emissions, causality from carbon dioxide emissions to energy consumption, causality from GDP to energy consumption, Causality from capital to energy consumption, causality from capital to GDP, The cause of carbon dioxide emissions to open trade. Causality from energy consumption to open trade, causality from capital to open trade and so on There is causality from GDP to open trade. Iran has a relative advantage in energy consumption due to its huge resources of oil and gas, which has caused the emission of pollutants by the gross domestic product.Discussion: According to the results in Iran, there is causality from gross domestic product to energy consumption and carbon dioxide emissions, which shows that Iran does not need to reduce its economic growth in order to reduce carbon dioxide emissions. It indicates that energy consumption and carbon dioxide emissions in Iran will not lead to economic growth. Iran can follow a conservative energy policy and a policy to reduce carbon emissions in the long term without creating obstacles and reducing economic growth. Economic growth has led to the emission of pollution and it is possible to pursue economic growth without the emission of pollution by using sustainable development policies. The causality is from economic growth to energy consumption, trade and capital. According to the directed acyclic diagram (DAG), the Granger causality test was investigated in the variables of economic growth, open trade, capital, carbon dioxide emissions and energy consumption. According to the results of this research, Granger causality has started from economic growth to other variables.

Financial development is one of the goals of countries. This study investigates for the first time the impact of financial development on environmental pollution and energy consumption with the method of generalized torque, dynamic least squares and adjusted minimum squares in OPEC member countries in the period 1992-1992. Iran has a comparative advantage in energy consumption, so research in this area is necessary. According to the results of financial development, it has had a positive and significant effect on environmental pollution in these countries in the form of three models, and indicates that financial development in these countries has not led to the creation of environmentally friendly technologies. Energy consumption, GDP and urban growth have a positive and significant effect on environmental pollution. The Kuznets curve in these countries is confirmed by an inverted U-shape. Financial development with dynamic least squares and adjusted ordinary squares has a positive and significant effect on energy consumption.

Expand the usage of Internet and consequently reducing the digital divide between developing and developed countries, shows the study of effect this variable on the energy consumption and air pollution in developing countries is important. In this regard, the main objective of this paper is to examine the impact of the Internet's influence on energy consumption and CO2 emission in Iran Using time series data 1995-2016. The results using co-integration five-step Johansson (1992) method showed a positive impact of Internet on the per capita energy consumption in the long term. A one percent increase in the number of Internet users (per 100 people), in the long run, increase the per capita energy consumption in Iran by 0.19 percent. Accordingly, the move to the policies and programs that take advantage of the Internet to reduce energy consumption in the country is essential. Also, the long-term impact of the Internet on air pollution is positive, but it is negligible. So that a one percent increase in the number of Internet users (per 100 people), in the long run, increase the level of CO2 emissions in the country by about 0.06 percent. Accordingly, it can be said that the increase in Internet usage is not a serious threat to air pollution in Iran.
