Today, air pollution caused by greenhouse gas emissions is one of the most important environmental issues in the world. Carbon dioxide has the greatest share in greenhouse gas emissions. In Iran, the industry sector plays a major role in carbon dioxide emissions, with around average of 16/1 percent, during the 2000s. Some areas like metropolises and industrialized provinces have a great share in air pollution, because of their industry concentration. East Azarbayjan province is one the industrialized and polluted provinces of Iran. In order to reduce the emissions of greenhouse gases such as carbon dioxide, the recognition of influencing factors of emissions of such gases is required. Accordingly, in this study the carbon dioxide emissions of manufacturing industries in East Azerbayjan province is decomposed to activity, structure, energy intensity, fuel mix and emission factors, for the period 2001-2014. The results indicate that the changes in the activity level and emission factors are the major factors of increasing carbon dioxide emissions in East Azarbayjan province, respectively. In contrast, changes in energy intensity, the structure and fuel mix factors played roles in reducing carbon dioxide emissions.
