Carbon Dioxide (CO2) resulting from the combustion of fossil fuels has the highest share of greenhouse gas emissions. Non-metallic mineral products industries with a share of 25.8 per cent had a significant role in CO2 emissions of Iranian ten people or more industries at 2011. In order to have knowledge about the changes of such pollutions, the recognition of the influencing factors of emissions of them is required. In this study, using the LMDI approach, the changes in total CO2 emissions in Iranian non-metallic mineral products industries are traced back to changes in activity level, structural change between sectors, structural change within sectors, energy intensity, fuel mix and emission factors, over the period of 2000 – 2011. The results indicate that the changes in the activity level, structural change between sectors and emission factors are the major factors of increasing CO2, respectively. In contrast, changes in the energy intensity, structural change within sectors and fuel mix factors have decreased the CO2 emissions of such industries.
