Today, energy demand has increased as a result of population growth around the world. Due to the limited fossil energy resources and the problems caused by greenhouse gas emissions, it is necessary to pay more attention to renewable energy, because in this way, the goals of sustainable development can be achieved. Therefore, the purpose of this study is to properly evaluate the performance of renewable energy technologies and also to investigate the relationship between renewable energy, carbon dioxide emissions, and sustainable development in Iran and compare it with non-renewable energy. In order to rank renewable energy carriers and identify the best type of them for electricity generation in Iran, a multi-criteria decision model has been used. In this regard, by conducting library studies and collecting the opinions of experts, a set of criteria in the form of four technical, economic, social, and environmental dimensions has been determined. Then, using the VIKOR approach, renewable energies consisting of wind, hydropower, solar, biomass, and geothermal energies are discussed. Findings indicate a high priority of wind energy and solar, hydropower, geothermal and biomass are in the next ranks. The results indicate that the effect of positive momentum on the share of renewable and non-renewable energy on sustainable development in Iran is positive.

In the present study, the approach of a recursive dynamic computable general equilibrium was used in order to simulate the economic and welfare effects of the allocation of oil revenues in the Iranian economy. Accordingly, changes in the production index of different economic sectors, changes in consumption and price levels in the form of 4 scenarios of different combinations of depositing oil revenues to the National Development Fund of Iran, and using the social accounting matrix (SAM) related to the year 2011 were considered. The results showed that by using different scenarios of oil revenue allocation, the highest growth of production and consumption of the studied sectors compared to the basic scenario of the fourth scenario (save 20% of oil revenues in the country's foreign exchange fund and invest 30% of the fund's resources in the industry) will be. Meanwhile, the highest rate of price reduction in the production sector is related to the fact that 20% of oil revenues are saved in the country's foreign exchange fund and no amount has been invested in the economic sectors. In fact, the increase in production and boom is due to the increase in investment in the industrial sector of inflation and will lead to the growth of prices of manufactured products. Therefore, by allocating the fund's resources in the industrial sector, the goal of economic growth and increasing household welfare will be achieved. In fact, due to the strong links between the industrial sector and other sectors, including agriculture and services, by investing to improve the productivity of the industrial sector, all economic sectors have benefited from this issue and by increasing production while growing demand for investment and increasing household consumption will bring greater welfare to consumers.

The main purpose of this study is to investigate the effect of economic and social factors on the emission of carbon dioxide, which has been used as a measure of environmental pollution in Iran for the period of 1352-1397. In order to measure the economic and social factors affecting environmental pollution, it is necessary to study the short-term and long-term relationship between fuel oil consumption, urbanization, economic growth, and carbon dioxide emissions in Iran. For this purpose, the autoregression model with extended distribution intervals (ARDL) was used. The results show that the error correction coefficient obtained in this model shows that in each period, 33% of the short-term failure error can be made to achieve a long-term comparison. According to the estimate, the increase in fuel oil consumption, urbanization, and economic growth have a positive effect on carbon dioxide emissions both in the short term and in the long term. Also, the long-term results indicate that with an increase of one percent of gross domestic production, fuel oil consumption and urban population increase carbon dioxide emissions by 0.849, 0.166, and 1.566 percent, respectively. Therefore, the first step to reduce carbon dioxide emissions in the country is to pay attention to the amount of fuel oil consumption, hence policies can be made to use alternative energies such as renewable energies to reduce carbon dioxide emissions.

In analyzing the efficiency of electricity distribution companies, according to the economies of scale hypothesis, due to the existence of natural monopoly properties, larger firms are expected to be technically more efficient (ceteris paribus). To investigate this issue, this study assessed the technical efficiency, economies of scale, and economies of scope of Iranian electricity distribution companies during 2011-2017 and examined their relationship with company size. For this purpose, the stochastic frontier analysis technique and the input distance function approach were used. The results show that technical efficiency first decreases and then increases with increasing company size. The results also show that economies of scale are present in most companies, although the use of economies of scale decreases as company size increases. Finally, economies of scope were observed in all the companies studied, and their magnitude decreases as company size increases. Therefore, it can be said that the hypothesis of economies of scale implying higher technical efficiency of larger companies, is not confirmed, although the necessary condition for the establishment of a natural monopoly is present in Iranian electricity distribution companies

Managing energy consumption in smart buildings has become an increasingly important challenge. Efficient energy management can have a positive impact on both micro and macroeconomics. Moreover, it is essential to ensure that the comfort of smart building residents is maintained at an acceptable level. Optimization algorithms can be used to achieve user convenience while minimizing energy consumption. In this study, we propose an optimization approach that utilizes an agent-based architecture. This architecture comprises intelligent agents that communicate with each other via message exchange in a network structure consisting of three layers: (1) The switch layer monitors user preferences and comfort levels. (2) The coordination layer includes a coordinating agent that determines the optimal timing for electrical appliances to minimize electricity consumption costs and maximize user comfort. (3) The execution layer contains performer agents. Our focus in this research is on the coordination layer with the aim of reducing energy consumption costs and peak average rates, while increasing user comfort to the highest possible level. However, this optimization problem is highly complex due to the large number of electrical devices and their capabilities. To address this, we propose a hybrid method based on genetic and bat algorithms. We evaluated its performance based on objective functions and compared it with recent research on SmartHome and CU-Bems datasets. Our results demonstrate an improvement in performance

In economic theories, Fiscal decentralization represents the shifting of decision-making power about the composition of tax revenues and non-tax revenues or expenditures are from the government to local units to provincial government officials, which leads to increased efficiency in resource allocation. And, since the pioneering study of Oates (1972), fiscal decentralization and its effects have garnered significant attention among economists. In the past years, global warming, carbon emissions, climate change due to increased energy consumption have brought the issues of fiscal federalism versus provincial institutions to the agenda of policymakers and energy research institutes. Because fiscal federalism can play a crucial role in reducing non-renewable energy consumption, promoting renewable energy, and reducing carbon emissions. Hence, energy economists have endeavored to shed on the association between fiscal decentralization and energy consumption and carbon emissions. In this way, this paper examines the effect of fiscal decentralization, in the form of shifting revenues and tax incomes responsibilities from the government to provincial institutions, as well as raising of the urbanization, GDP, and energy price on energy consumption for 31 Iran provinces from 2006 to 2020. To this end, this paper employs Quantile Regression with Non-additive Fixed Effects to analyze the impact of fiscal decentralization on energy consumption. The results of this study show that fiscal decentralization has a non-linear relationship with energy consumption. In addition, the rising urbanization and GDP lead to high demand for energy consumption. Moreover, the rising energy price leads to low energy consumption.

There have been many studies on economic sanctions and the effectiveness of these sanctions. In these studies, the sanction variable treats as one or two dummy variables (binary), to indicate at most four levels (no sanctions-mild sanctions-severe sanctions-comprehensive sanctions). Studying the effectiveness of economic sanctions requires recognizing the extent and severity of sanctions in various sectors, so it is not possible to examine the effectiveness of sanctions and any review of economic sanctions independent of the severity and extent of sanctions. To this end, in this article, we present the severity of sanctions imposed on the energy sector to a variable between zero to five to provide a better indicator to understand the pressure of economic sanctions imposed on the energy sector of Iran. We examine the effectiveness of sanctions by entering the sanctions severity variable on Iran's foreign trade with five major trading partners, including Germany, China, India, United Arab Emirates, and Turkey, based on the gravity equation through an interactive dummy variable method. We tried to present all the sanctions imposed on Iran's energy sector, between 1992 and 2018. The results show a significant and negative effect of the intensity of energy sector sanctions on Iran's foreign trade. China and UAE have the lowest response to sanctions on Iran’s Energy sector. Also, the highest reduction of trade with Iran due to energy sector sanctions is dedicated to India and Germany.

This research conducts a quantitative comparative analysis of the dynamic international crude oil trade network of Iran by using the network connectedness measures of Diebold and Yilmaz (2015) and also the asymmetric short-term and long-term impact of the increasing and decreasing key driving factors and obstacles in the crude oil trade development through the gravityrelation and by using the nonlinear panel auto-regressive distributed lag (ARDL) model during 1980–2017. Results indicated the dynamic spillover flow of the crude oil trade of Iran during the investigated period of time. Moreover, the crude oil trade flow of Iran is a net shock transmitter to Middle East and a net shock receiver from the crude oil trade flow in countries of America, Eastern Europe- Eurasia, Africa, Western Europe, and Asia Pacific, respectively. The focus on the divided regional trade scheme and adopting the biased foreign trade policies by Iran may not lead to the vulnerability reduction of its economy from crude oil trade flow volatilities. Findings also reveal the asymmetric behavior of the crude oil bilateral trade flow in response to the increasing and decreasing of gross domestic product (GDP) per capita variables in both crude oil exporting and importing countries and international crude oil transportation costs in the short-term and long-term period that it can be used in identifying the effective factors on the volatility transmission to adjust the crude oil trade flow. Therefore, concerning the high degree of the integration in the international crude oil trade network of Iran, it seems that it is necessary to prioritize cooperative over competitive behavior in the crude oil trade of Iran and respond appropriately to market shocks and volatilities during the time (risk management) in the economic plan of the country.

Natural gas has a special place in relation to other energy carriers due to its environmental advantages in energy consumption policies. Also, among the various energy consuming sectors in the country, the share of the domestic sector in natural gas consumption is higher than that of other sectors. The aim of this study was to investigate the function of natural gas demand using an almost ideal demand system. For this purpose, the data of Khuzestan province during the period of 1988-2018 were used and the equations were estimated with the help of seemingly unrelated regression methods. The Calculation of intrinsic price elasticities using constrained and non-constrained models showed that all these elasticities were negative. So that in the constrained and non -constrained model, the intrinsic price elasticity of natural gas is 0.92 and 0.9. Also, the study of natural gas income elasticity in the non -constrained and constrained models is positive and 0.9608 and 0.9613, respectively, and indicates that natural gas is an essential commodity in the basket of Khuzestan households

Despite the importance of energy inequality issues in Iran, the depth and extent of this issue have been neglected and have not been examined. The necessity of social justice, having an advanced society, and reducing the effects of energy inequality in the economic, social, and cultural growth and development in a country, cause this issue to be investigated. The goal of this study is to identify and evaluate the factors that play an important role in energy inequality. Hence, this study investigated the impact of economic-social parameters on energy inequality by using the combined data method for 31 countries during 2009-2020. This research results show that three factors of population, energy price, and GDP have a negative and significant effect on the inequality of energy consumption. Also, variables such as government current expenditures and education have a significant and positive effect on energy consumption inequality. On the other hand, urbanism and development expenditures of the government have no noticeable relation with energy inequality

The purpose of this research is to investigate different levels of country risk and its role in the relationship between renewable energy consumption and economic growth in Iran, during the period (1997-2021). In terms of purpose, this research is of applied type and in terms of causal-analytical method, and the method of collecting information is of documentary-library type. After calculating the threshold value of each variable, we analyzed the effect of renewable energy consumption on economic growth using the threshold distance of different country risks. The results indicate the non-linear effect of renewable energy consumption on economic growth under different risks in the country. This research is one of the first studies in Iran that analyzed the relationship between renewable energy consumption and economic growth based on a risk-based approach. According to the regression model described in the current research, this research provides suggestions for developing a suitable strategic plan with the aim of specifying short-term and long-term goals, and future vision, as a road map for those involved.

One of the issues which internationally is important in the oil industry is related to the Upstream industry of oil contracts. Changes made in these contracts consist of differences made directly in relation to the importance of the number of hydrocarbon sources and the number of shares each party is going to gain. If more structure of these contracts is emphasized and fortified, more duties and places of each party will be complicated. In this research, the comparison is made between two contract models which have been recently proposed and overviewed. The criterion used in selected contracts is from the National Iranian south oil company (NISOC) and Iranian Petroleum Contracts (IPC). The research has concentrated on the efficient economic cost role used in these contracts. A questionnaire was conducted based on the analytical hierarchy process, and a survey was conducted among the professionals of the oil industry. The results showed that most of those who participated in the survey agreed that the National Iranian South Oil Company’s Contract (NISOC) has a better criterion for the efficient role in economic cost

The purpose of this study is to compare the economic efficiency of Iran's petroleum contracts, buyback contracts, and production-sharing contracts. This study also determined the optimum path for production and drilling operations in the Yadavaran oil field which has special importance because it is a joint field with Iraq. It was estimated using real field data and the SQP algorithm by MATLAB software. First, the objective function, the constraints of each contract model, and the cost function are defined and expressed based on field data. For the objective function, the oil price is determined based on the reference price scenario and based on the forecast of the US Energy Information Administration (EIA). Cao et al (2009) 's cost function model is also modified by using historical field data (first development phase data) to be applied to the study field. The results show that the most efficient oil contract is the Iran petroleum contract, with a low floor for capital costs and no limit to the number of drilled wells. it was proved that the buyback contract with the ceiling of capital costs incompatible with the recovery coefficient has recorded the lowest efficiency. Also, the Iran petroleum contract can be a good alternative to the buyback contract, because it can well solve the problems of the buyback contract, especially for joint oil fields where the priority of the objective function of the maximum cumulative production over the objective function of the maximum present value of the total profit is more desirable.

Due to the heavy reliance on oil revenue in oil-exporting countries, fluctuations in oil prices can impact the social behavior of individuals within society. As a result, it appears that social capital, as a process of social institutions, is affected by oil rent. The purpose of this research is to investigate the impact of oil rent on social capital in selected OPEC oil-exporting countries from 2009 to 2020 using the threshold panel method. The findings indicate that the threshold value for the ratio of oil rent to GDP is estimated at 3.4%. Prior to this threshold, the ratio of oil rent to GDP had a positive and significant effect on social capital; however, after surpassing this threshold, the ratio of oil rent had a negative and significant effect on social capital. Inflation also had a non-linear effect on social capital, while government size did not have a significant impact. Based on these results and the detrimental effects of high levels of oil rent on social capital, it is necessary to control methods that divert oil resources towards rent-seeking activities. One solution could be removing control over oil rent from governments and transferring it directly to citizens. Experience with government management of oil has shown that instead of optimal allocation, most funds have been spent destructively; therefore, mismanagement has turned this divine gift into a curse.

Investigating the effects of climate change on different aspects of social life has been the focus of research in recent decades. The importance of energy for development and growth as well as pollution caused by energy carriers has made it necessary to assess the impact of climate change on the consumption of various energy carriers including natural gas. This study designed a model for natural gas demand in which in addition to the conventional economic factors, climate variables are considered. Then, we estimate this model for Iran during the years 2003-2015. In addition, variables of GDP and electricity consumption as well as trend variable had the greatest effect on natural gas consumption in the country.

Energy intensity is an important indicator of energy consumption assessment and its reduction is one of the goals of policymakers and planners in countries. Developing effective policies to reduce energy intensity requires a thorough study of the factors that affect it. In this study, the effect of foreign direct investment on energy intensity convergence by Iranian provinces using spatial econometric technique and panel data of 30 provinces of the country from 2010 to 2015 was studied. After confirming the spatial dependence by Moran and Panel (robust) LM and LM tests, the absolute and conditional convergence of "β" has been tested. According to the results, the absolute convergence of energy intensity in the provinces of Iran was confirmed. This means that the rate of decrease in energy intensity in provinces with higher energy intensity is higher than the rate of decrease in energy intensity in provinces with lower energy intensity. To investigate the conditional convergence, the foreign direct investment variable was added to the model. The results indicate a conditional convergence of energy intensity in the provinces of Iran, as well as a decrease in energy intensity with an increase in foreign direct investment. In fact, foreign direct investment with the introduction of new production technology increases the efficiency of the use of production inputs such as energy, and this leads to the convergence of energy intensity among the provinces of Iran. The effects of the spillovers of foreign direct investment on the convergence of negative and meaningless energy intensity can be attributed to the low level of foreign direct investment attraction and its non-distribution at the provincial level. In general, the increase in foreign direct investment in a particular province causes the convergence of energy intensity and its spillovers effect potentially causes the convergence of energy intensity in the provinces of the country.

The main goal of this research is to design a composite economic-energy-environmental performance index (3EPI) for Iran's economy by generalizing the methodology of Khramov and Lee (2013) as well as evaluating the effect of variables on the composite performance index during the period from 1991 to 2021 using a time-varying parameters model (TVP). The 3EPI index is calculated in a weighted and unweighted form, and the trend is separated from the cyclic with the Hodrick-Prescott filter. The findings show that the long-term trend of the 3EPI index is in the range between 35 and 60 percent, which is significantly different from the base number of the index (i.e. 100 percent). The chronicle of the index shows that the worst performance is related to the implementation period of the structural adjustment policy (1994 and 1995), the first round of economic sanctions (2012), and the intensification of economic sanctions in the latest round of sanctions (2019). The best performance is related to the two periods of the relative stability of macroeconomic variables and the period of implementation of the JCPOA agreement. The results of the application of the TVP model show that, from 2011 to 2021, the variable of the budget deficit to GDP ratio had the most significant negative impact on Iran’s 3EPI performance index

The present research has been conducted with the aim of the pathology of conservation in the production of the Parsi oil field and providing solutions for improved maintenance production process. For this purpose, using the SWOT approach and analyzing the information collected from the questionnaires was completed by experts and specialists of the National Iranian Oil Company in 1400. The results indicate that the production conditions of protection in the situation of conservative strategies are based on the final scores of the internal and external factors of the SWOT matrix, which are 1.988 and 2.67, respectively. Also, the results show that the expertise and efficiency of the workforce and the existence of knowledge and technology required to use reservoir-based overdraft methods with scores of 0.24 and 0.177, respectively, are the most important strengths. Moreover, lack of principle of safe production in practice due to reasons and lack of comprehensive and specialized planning in accordance with the goals of safe production to convert potential oil into actual at the ministry level with scores of 0.063 and 0.062, respectively, have been identified as the most important weaknesses. In addition, the support of upstream documents on the conservation in the production and the nationality of the NISOC with scores of 0.228 and 0.224, respectively were identified as important opportunities. It should be noted that the existence of restrictive regulations and programs of the Ministry and the existence of some anti-conservation in the production of oil contracts with scores of 0.057 and 0.056, respectively, are the main threats. Therefore, the existence of integrated management with a focus on the conservation in production and attention to internal and external factors could improve the conservation in the production process.

The curse of natural resources is an emerging phenomenon that is of interest to economic researchers. The attention of researchers is about the direct effects of resources on economic factors. The subjects of these researches are around axes such as the impact on growth, productivity, and production incentives. In the research conducted, special attention has been paid to how the abundance of resources affects macroeconomic factors such as the Dutch disease; but what is not considered is the investigation and analysis of the side effects of abundant resources on economic, social, and political indicators. One of the side effects of the abundance of resources can be its effect on the spread of economic corruption. In case of an abundance of natural resources, the potential for widespread corruption is created. This research was done in a descriptive and analytical way. It has investigated the relationship between the extent of economic corruption and the abundance of natural resources. To conduct this research, the statistics of selected developing countries in the period of 2000-2021 have been used. The information used in this research is the indicators of the perception of corruption, fuel export of countries, and economic freedom during the research period, which is from reliable sources such as the United Nations, Transparency International, and the Heritage Foundation. Multivariate panel data regression method with random effects has been used to estimate model parameters. The results of this research show that there is a negative and significant relationship between the corruption perception index and the fuel export index of selected countries, so that in the 95% confidence interval, the estimated coefficient of the independent variable is negative 0.01. For economic freedom, it is 0.07, which is in line with the results of other researches in this field. Therefore, it can be stated that the abundance of natural resources has a direct relationship with the extent of economic corruption.

Pollutants emissions intensity in Iran which is mainly originated from energy consumption is higher than those of the global one. In this context, the current study aims at investigating emissions intensity determinants in the Iranian economy. To get the objective, decomposition analysis (index decomposition technique) was applied to decompose the energy intensity to its components. Then, the determinants of emissions intensity were examined using the regression model. The selected pollutants are NOx, SO2, CO, CO2. The data were related to 1367-96 (1988-2017). The results for all pollutants revealed that emission coefficient (emission per unit of energy) and energy intensity in services and manufacturing sectors have the highest contribution to emissions intensity. The findings suggested that the manufacturing sector plays a central role in SO2 emissions and a 1% increase in emission coefficient and energy intensity in the sector will increase emissions intensity by 0.6 and 0.5%, respectively. The services sector has a more important role in the emissions of the remaining pollutants and the corresponding values are 0.8% and 0.45-0.9%, respectively. Furthermore, urbanization could increase emissions intensity significantly. However, economy openness failed to affect emissions intensity significantly..

Given the importance of oil prices, proper prediction of the OPEC Reference Basket can have an essential role in the immunization of economies in these countries against the effects of these fluctuations. This research is an effort to introduce an optimal model for modeling and predicting the fluctuations in OPEC crude oil prices. In this regard, we used data of daily oil prices between 2/1/1986 and 13/2/2017. According to this, the existence of long-term memory in the average equations and variance of crude oil prices were assessed and modeled and the result of the ARFIMA, confirms the existence of long-term memory in both the average equation and series variance. However, tests confirm non-linear and exponential behavior in crude oil prices. For this reason, results are specifically based on the information criteria and also MAPE and indicate the selection of a mixed model of partial augmented average movement and the model of conditional exponential Heteroscedasticity EGARCH (1,1) AFIRMA (4,0.09,3) as the best model for modeling and predicting the OPEC crude oil fluctuations in prices and lack of attention to exponential non-linear variance in the long term memory of crude oil prices can cause an error in the calculation of analysts and especially economic decision maker and deviation optimal policies.

Energy has always played a very important role in human life and is one of the factors that can make economic growth possible. Today, many countries are struggling to invest in new technologies by using renewable energy sources such as solar energy, wind energy, or water energy as their needed sources of energy, which, as compared to fossil fuels, generate lower environmental pollution. The purpose of this study was to evaluate the economic growth of the selected countries of the MENA region from renewable energy sources using the Panel Vector Autoregressive Model in the period of 1990-2015. The results of the study showed that the variable of the total energy produced from renewable sources has the largest share in explaining the changes in the economic growth of the countries under study and its explanatory value reaches 56% in the long run. Given the significant impact of renewable energy consumption on economic growth, suitable policies for renewable energy are needed to achieve a high level of production and social welfare. In this regard, granting financial incentives, establishing a fund for renewable energy by the government, and creating conditions for developing the renewable energy industry in the country could be solutions

Reducing greenhouse gas emissions is one of the most important goals of the world’s energy and environmental policies. Even though fossil fuels are one of the most important factors in creating pollution, their role in the structure of production and economic growth cannot be ignored. Nowadays, to measure economic growth, economists do not consider only the amount of production of goods and services, but also consider the structure of production of goods and services in terms of technical knowledge (technology level) used in them. Accordingly, in recent decades, the index of economic complexity has been proposed, and by calculating it the possibility of knowing the development of countries’ levels is provided. The purpose of this study is to investigate the effect of the economic complexity index on greenhouse gas emissions in some oil exporting countries in the period from 1995 to 2019 using the panel smooth transition regression (PSTR) model. The results of the linearity test confirm the existence of a nonlinear relationship between the considered variables. Also, considering a transfer function with a threshold parameter that expresses a two-regime model is sufficient to specify the nonlinear relationship between the model variables. The slope parameter (transition speed) equals 3/1964. The test results indicate that in both regimes (first and second), the economic complexity index has a negative effect on the amount of greenhouse gas emissions

The purpose of this paper is to evaluate the role of ICT due to ecological footprint from the perspective of individual effect and the trend of the 113 countries' reserves and land production in selected developing countries using the data panel method in the period 1992-2018. The results showed that increasing the mobile penetration rate increased greenhouse gas and carbon dioxide emissions and increased the ecological footprint effect. However, increasing the Internet penetration rate has reduced carbon dioxide emissions, increased greenhouse gases, and increased ecological footprint. Therefore, ICT use in these countries has not yet been effective in improving the environment. In the short term, there is a positive relationship between economic growth and environmental degradation in these countries, and economic growth worsens the quality of the environment. And in the long term, there is evidence of the Kuznets hypothesis being correct. Dynamic analysis showed that the use of ICT has been effective in improving the environment and this effect lasts for at least a decade. Technology shocks have an immediate effect on improving some environmental indicators and the range of effects on some indicators appears in the long term. In these countries, the production of ICT has no relative advantage, but they can benefit from the economic and environmental benefits of ICT.

According to apposite and ambiguous opinions about the effects of foreign direct investment and innovation on environmental performance in developing countries, in this research despite the environmental Kuznets curve (EKC) hypothesis, pollution haven hypothesis (PHH), and rebound effects hypothesis (REH) in D8 countries (Iran, Turkey, Malaysia, Indonesia, Egypt, Pakistan, Bangladesh, and Nigeria) were studied. For this purpose, the required data was gathered from World Bank during the years 2000-2018. Also, the fully modified ordinary least squares (FMLOS) model and STATA software were applied for analyzing data. Results of variables description indicated that during the studied period, Iran has the lowest average amount of FDI to GDP, the lowest average amount of per capita GDP growth, the highest average of the proportion of fossil energies to total energy consumption, and the highest average of the proportion of per capita CO2 emission. In addition, the results of the specification of the econometrics model showed that there is a U inverse relationship between GDP and CO2 in D8 countries. Therefore, the EKC hypothesis is approved for studied countries. Also, foreign direct investment has a positive significant effect (in 10%) on CO2 emission. Hence, the PHH hypothesis is approved for studied countries. Finally, innovation has a negative significant effect (in 5%) on CO2 emission. Hence, the REH hypothesis didn’t approve for studied countries.
