In the 21st century, environmental pollution and global warming is one of the most important problems such as poverty, hunger, terror and epidemic diseases. On the basis of environmental pollution, which is now accepted as a global problem, phenomena such as increasing energy demand due to industrialization and technological development and increasing fossil fuel consumption, population growth rate, and urbanization are the underlying factors. Different methods of struggle have been adopted at national and international scale in order to eliminate negative externalities caused by environmental problems or to minimize the negative effects on human and environmental health. The first and only tax introduced in the Turkish Tax System within the scope of combating environmental pollution is the Environmental Cleaning Tax. Plastic Bag Tax should also be evaluated in this context. Although it is not a direct environmental tax, Motor Vehicle Tax and Special Consumption Tax are also considered as other environmental taxes since it provides environmental contributions in terms of tariff, rate, exemption and exceptions. It is seen that the environmental taxes included in the Turkish Tax System do not have the desired level of environmental impact. For this reason, environmental taxes should be used effectively together with other financial or market instruments within the scope of the fight against environmental pollution.

This study investigates Turkeys' greenhouse gases, economic growth and energy consumption relations by using 1960-2010 data for the related indicators. For this purpose, Dynamic Ordinary Least Squares method was developed. Ampirical results does not support Environmental Kuznets Curve hypothesis, which suggest the relationship between the income per capita and carbondioxide emissions are inverted U-shaped. Our results have found inverted N-shaped relationship between these two variables. The results also found a significant and positive relationship between energy consumption and ghg emissions.
