This paper suggests that Pakistan has a significant energy supply and demand mismatch. In the energy sector, accurate measurement is necessary to provide a prediction that aids in creating a strong framework for future work and policy. We must quickly shift the energy generation toward renewable energy sources in order to keep global warming under strict control and recognise it as a serious issue. Pakistan should move as quick pace for shifting its energy production from fossil fuels to clean and renewable energy that needs the US $211millions for increase in supply of electricity per capita. This study is done for the analysis of decarburization potential of Pakistan energy sector to increase the clean energy input in line and reduce CO2 emissions. Two different scenarios are considered in this analysis based on the results a conclusion has drawn in cross examination of the scenarios best suitable for mass application at national scale. To make Pakistan greenhouse gas free nation at global scale decarburization of energy is inevitable. While analyzing carefully it is suggested that Pakistan has correct and up to the scale potential of decarburization of energy at 23% per annum gradually till 2035 with 12 million US Dollars cost involved overall.
