Economic growth, with its general definition, is the realization of the increase in real GDP per capita. The first goal for countries is to achieve economic growth. In addition, it is important that economic growth takes place in a sustainable manner. For economic growth, especially after the industrial revolution, the consumption of energy resources has increased. However, the consumption of energy resources has caused various environmental problems. From another point of view, the population in cities is gradually increasing and accordingly, there is an increase in the use of energy resources to meet the needs of people living in cities. The most important environmental problem that arises is the greenhouse gas emission to the air, and greenhouse gas emission is generally expressed as CO₂ emission. Countries increase their energy consumption in order to realize their economic growth, and in this context, it is seen that there is an increase in CO2 emissions in countries. The Kyoto Protocol was signed by the United Nations in 1997 to prevent greenhouse gas emissions.
