Air Pollution: Key Environmental Issues in Pakistan(W-99) | | |  | | | |Mahmood A. Khwaja and Shaheen Rafi Khan | |2005 | |Air pollution is rapidly growing environmental problem in Pakistan. Highly inefficient energy use, accelerated growth in vehicle | |population and vehicle kilometers traveled, increasing industrial activity without adequate air emission treatment or control, | |open burning of solid waste including plastic, and use of ozone depleting substances (ODSs) are some of the major causes of | |deterioration of ambient air quality. | |Some key environmental issues about air quality in Pakistan have been assessed and discussed, using the Pressure, State, Impact | |and Response (P-S-I-R) framework. | |Rapidly growing energy demand, fuel substitution such as high emitting coal and oil, and high-energy intensity are the key factors| |contributing to air pollution. Some factors contributing to high-energy intensity are transmission and distribution losses in | |power generation, fuel prices subsidies on diesel and ageing vehicles, which are primarily diesel powered. | |  | |The state of air quality has been assessed by examining the emission...
