BACKGROUND AND OBJECTIVES: As the population grows on the earth, transport and industrial sector have become the main parameters whose emissions increase pollutants like greenhouse gasses that have a snowballing impact on urban air quality and life in the area. This study aims to analyze the emission of greenhouse gases in the highly urbanized city of Karachi through Geographic information technique.
METHODS: This study used the Inverse distance weighted technique of Geographic information system to highlight the emission of greenhouse gases in ten different sites of Karachi, Pakistan. Target areas include Baloch colony, Clifton, Civic center, Garden police headquarters, II Chundrigar, Karimabad, Korangi, Nazimabad, SITE area and SUPARCO.
FINDING: Results showed that Baloch colony, Korangi, Nazimabad, SITE area and Garden police headquarter lies in the highly polluted areas among these ten sites of Karachi city. Karimabad with moderate pollution, II Chundriger and SUPARCO with low pollution rate and Clifton had very low pollution.
CONCLUSION: As all of the observed ten sites of the city have dense populations with heavy traffic and industrial pollution, there is a need to take serious steps towards areas indicated in this study to safeguard the people from the effects of GHG emission. With the help of this study the general population and all concerned authorities with highly polluted areas, can be familiarized so that efficient and different ways to overcome the pollution, like plantation, can be applied.
