The increase of greenhouse gases (GHG) in which CO2 emissions constitute the principal component, is of major environmental problems of all societies. Economic growth impels intensive use of resources and as a result, more residues and wastes thrown in the nature that could lead to environmental degradation. This article tries to trace the eventual relationship between trade openness and environmental degradation in Iran. For this purpose, a multivarate model is employed in which economic growth and trade openness are related to CO2 emissions for the period of 1971-2006. By carring out the Granger causality test, there appeared a unidirectional relation from trade openness to CO2 emissions. To analyze the variables’ relationships, the approach of GMM is applied. Results indicate that economic growth has a significant negative effect on carbon dioxcide emissions. But, the impact of trade openness on carbon dioxcide emissions is significantly positive.

This paper examines the non-linear relationship between CO2 emissions and economic development using an innovative dynamic panel threshold technique. The sample consists of 35 developed countries over the period 2003-2010. The empirical results indicate that there is a threshold effect in the relationship between economic growth and pollutant emissions as suggested by the environmental Kuznets curve (EKC). In particular, at the early stage of economic development below the estimated threshold value, more growth deteriorates the environmental problems. However, after this threshold value further growth serves as a solution to the environmental problems. Accordingly, promoting economic growth and becoming rich in the long run, is necessary to solve the environmental problems arising from greenhouse gas (GHG) emissions. In the short run and in the early stage of economic growth, focus on investments in environmentally friendly technology and on the use of renewable energy is necessary for mitigating the pollution effects of economic progress.
