摘要：This study examines economic benefits of Compressed Natural Gas (CNG) vehicles in Pakistan where social cost is explained by CO2 emission from transport (million metric tons), using time series data from 2000 to 2010 of Pakistan. The result shows that there exists a significant relationship of both economic & financial cost with CO2 emission levels. Individual effects of variables/predictors included in the model are illustrated. All three variables are found to be statistically significantly at 0.1. Increasing number of converted CNG vehicles are negatively related to overall CO2 emission through transport. It means CNG vehicles are reducing the social cost in Pakistan resulting in an overall economic benefit to society in terms of reduced CO2 emissions. The results proved that, with an increase in 1000 CNG vehicles on the road, CO2 emissions declined by .008 m metric tons. It is recommended that govt. of Pakistan should take some positive steps in order to improve economic and financial cost of CNG in Pakistan because in comparison with social cost of CNG in Pakistan, it can be deduced that financial/economic cost that has both positive and negative relationship. The results also show that CNG is contributing less in the overall pollution level in Pakistan as compared to other burning fuels.
