Although economic growth is one of the most important objectives of governments, higher economic growth is mainly associated with an increase in environmental pollution. The experience of the developed countries and some developing countries shows that with increasing economic growth, first the environmental pollution is increased and then it is reduced due to the attention to the environment at the level of production per capita which can be shown in Kuznets environmental curve. The main objective of this study is to determine the level of per capita income which causes reduced emission of the pollution due to considering the environmental issues as well as studying the impact of technology overflow index on the turning point of the curve. In this regard, using the models of the demand of capital-intermediate goods import, technology overflow index was calculated and its effect on Kuznets environmental curve theory in the period of 1966 to 2013 was reviewed. The results showed that technology overflow variable not only had a positive impact and significant impact on carbon dioxide emissions, but it also made the Kuznets Environmental Curve's turning point possible in higher per capita income.
