In recent decades, economic growth along with environmental protection is important issue facing most economic societies. On the other hand, with the increase of new technologies and the trade openness, the effect of changing new and extensive structures on the environment has become very important. Therefore, the aim of this study is to evaluate the effect of economic complexity and trade openness on the ecological footprint (as an indicator of environmental degradation). For this purpose, the data of 18 developing countries in Asia during the study period from 1990 to 2017 have been used with the Panel-Quantile approach. In addition, the variables of GDP per capita, globalization and financial development were considered as control variables. The results of this study show that the increase in economic complexity in different quantiles reports different results, so that with a one percent increase in economic complexity in the 10th quantile, the ecological footprint has decreased by more than one percent, but an increase in economic complexity in the 50th quantile has caused the deterioration of the quality of the environment. The results show that the increase in trade in all quantiles has helped to improve the environment. Moreover, with increasing globalization and financial development, the ecological footprint has increased in all quantiles. In addition, the results of this study indicate that the increase in per capita income has reported different results in different quantiles.

The article purpose is analysis of decoupling relationship between CO2 emissions energy-related and economic growth in 6 Middle East countries in period 1990-2019. For this, CO2 emissions driving mechanisms were first quantified using Logarithmic Mean Divisia Index (LMDI) method, and then decomposed into factors of CO2 emission coefficient, energy intensity, economic activity and population. Next, the decoupling state of each country was analyzed using the Tapio model. The findings show that population and economic activities factors were main drivers of CO2 emissions in these countries. The results of decoupling elasticity showed that Iran was in a weak decoupling state in period of 1990-1999 and 2015-2019; It means the simultaneous increase of economic growth and carbon emissions, of course, by faster economic growth; Iran had also an expansive coupling state in period of 2000-2014, which indicates that CO2 emissions increase along economic growth. The UAE and Saudi Arabia have reached an ideal situation in recent years. These countries have moved from a negative decoupling and expansive coupling state to a strong decoupling state, where economic growth has been accompanied by a reduction in carbon emissions. The Kuwait and Turkey have been in a stable situation and have been in weak decoupling and negative expansive decoupling states in the last 3 decades, in which economic growth was accompanied by an increase in carbon emissions, but economic growth increased faster in Kuwait. At the beginning, the Egypt has changed to a weak decoupling state and then moved to an expansive negative decoupling state.

Greenhouse gas emission abatement is an important issue at the center of attention worldwide with the aim of achieving sustainable economic growth. One of the policies put forward in this area is to subsidize investment in research and development and to levy tax on fossil fuels in order to make appropriate technical changes to reduce greenhouse gas emissions. The present paper determines the subsidy rate for investment in research and development to double it with using a computable general equilibrium model. It considers in the first scenarios subsidy payment for investment and in the second scenarios subsidy payment along with, the taxation of fossil fuel consumption. It then examines the economic, welfare and environmental impacts of these policies. The results of modeling and calibration show that in the first scenario, the subsidy rate for investment in research and development is 9.4% and in the second scenario it is 9. 1%. Meanwhile, the tax rate for fossil fuels in the second scenario is 2.5%. The results indicate a reduction in welfare in both scenarios, regardless of the social gains of reducing emissions. The results also show that both the energy tax policy, and research and development subsidy policy is able to reduce energy consumption and air pollution.

Although the trend of increase in energy consumption has made possible fast economic growth of industrial modern society, but because of combustion pollutants emission and increase in density of carbon dioxide in atmosphere has made irreversible changes in the world. Not only this trend is destroying finite and nonrenewable energies, but also it is releasing numerous of pollutants into the receptive environment (air, water, and soil). In this article, existence of causality relation between energy carriers' consumption with economic growth and carbon dioxide gas emission in sectors of Iran's economy (residential, general and commercial, industry, agriculture, and transportation) in period of 1997 to 2012 using causality Toda and Yamamoto method has been studied. In the agriculture sector, results show a unidirectional causality relation of energy carrier consumption to economic growth. In transportation, residential, general and economic sectors existence of bidirectional causality relation of economic growth variable and carbon dioxide gas emission with energy carriers has been verified. In industry sector, a unidirectional causality relation of economic growth to gas, electricity to economic growth and bidirectional causality relation of coal exist. Also, there is a unidirectional causality relation of carbon dioxide emission to oil and bidirectional causality relation carbon dioxide gas emission to other variables except oil exist.

This research investigates the existence of relationships between economic growth and carbon emissions in the Organization of Petroleum Exporting Countries (OPEC) for the period of 1960 to 2005. A model relating economic growth and carbon emissions is used to examine the eventual existence of Environmental Kuznets Curve (EKC) hypothesis. To test our hpothesis, the econometric panel data approach is employed. The results indicate that there is a positive relationship between gross domestic product and CO2 emissions. And, with persistence of economic growth this relationship becomes negative. That is, the estimation has given an EKC relationship between GDP and CO2 emissions in these countrries.
