Human induced environmental impacts were started more than 10000 years ago with the agricultural revolution. However, after beginning of the industrial revolution which was almost 200 years ago, the most destructive human impacts have begun to be observed. Together with the industrialization, rapid population growth, huge energy demand, the unavoidable human impacts on the earth were started. The most important one is the climate change and global warming. During the 20th century, many evidences of global warming were proved by the scientists. Accelerating concentrations of the greenhouse gases (GHGs) – more specifically the increasing amount of carbon dioxide (CO2) emissions – in atmosphere are accepted as the main causes of climate change. Developed and developing countries have two different perspectives about the global warming. Developed countries suggest the immediate solution of the problem, by implementing the necessary energy and environment related policies to reduce the CO2 emissions and then stop the climate problem. However, developing countries firstly aim to accomplish their development and then to treat the environmental issues. Regarding developing countries, environmental issues have also become a certain problem starting from 1980s. The water and air quality in developing countries is worse than the developed countries nowadays which also create health issues in addition to environmental problems. Carbon dioxide (CO2) has the greatest share among greenhouse gases (GHGs) and it is widely accepted as the main reason of climate change and global warming. Therefore, this study firstly aims to decompose the CO2 emissions (which are the most important reason of the greatest environmental problem) in BRICs (Brazil, Russia, India, and China) and in MINTs (Mexico, Indonesia, Nigeria, and Turkey) from 1990 to 2011 to see the effects of different factors on CO2 emissions. A decomposition method which is called the refined Laspeyres index method (suggested by Sun in 1998) was utilized and the impacts of four main factors including economic activity, energy intensity, population effect, and carbon intensity have been considered. In addition, as a case study, Iran’s CO2 emissions have also decomposed for the same period to identify the factors that are affecting them. For Iran, both refined Laspeyres index method and logarithmic mean Divisia index methods were utilized to analyze the factor changing CO2 emissions and to provide a comparison between these methods. Empirical findings reveal that each of these factors has different impacts on each country’s carbon emissions. As a third aim, the decoupling factor that is suggested by OECD was calculated and the existence of decoupling between economic growth and environmental pollution was tested for every research country. Finally, different policy suggestions for each country have been provided.
