CO2 (carbon dioxide) emissions from fossil fuels have turned out one of the most perilous and complex issues driving the climate change debate. The issue of increasing demand for electricity at the same time reducing CO2 emissions has become important worldwide. This study evaluates the CO2 emissions from the power sector of Pakistan during 1978-2017 using Logarithmic Mean Divisia Index technique and scenario analysis. We estimate LMDI to check the change under prearranged elements. According to results, the shift in population, activity effects, and gross domestic product are the essential factors in charge of the increase in CO2 emissions while carbon intensity and energy intensity effects participate in cutting emissions. Finally, scenario analysis found overall activity increases due to population and intensity of CO2 emissions, but carbon intensity could be reduced by using cleaner energy technologies. The findings suggest that CO2 emissions will possibly arrive at 277.9 Mt in 2035 in Pakistan. In relation with the main findings, some targeted policies suggestions are provided.
