One of the most important challenges faced by governments in the 21st century is the environmental crises. For this reason, governments try to overcome the difficulties by adopting various policies and programs. Increasing the excessive use of fossil fuels is not only a threat to their future consumption, but its negative environmental impacts are also considered by governments as an important issues. Accordingly, in the study, welfare and environmental effects of green taxation policy is investigated by using computable general equilibrium method. Also, the changes in welfare, production rate and carbon dioxide emissions in 2015 in Iran have been evaluated through eight tax scenarios for the sectors of coal, oil, gas and oil products. The results show that by applying the tax on pollutants, in all scenarios, the changes in welfare are positive in terms of the positive effect of reducing pollution and its rate increases with the increase of the tax rate; however, the production rate is reduced in all of the scenarios. As a result, there is no double dividend in applying green taxes in Iran, also, the highest rate of the welfare growth is based on a 4 percent tax rate (fourth scenario), which is considered as an optimal rate.
