Abstract

Increasing greenhouse gas (GHG) emissions is worsening the climate change and its impacts all over the world. Currently there are number of techniques to estimate the GHG emissions and their concentration in the atmosphere. This study estimates the GHG (carbon dioxide, methane and nitrous oxide) footprint based on the one-year average fossil fuel consumption in selected Private Sector Universities of Karachi. The annual average GHG emissions from all of the universities were calculated to be 2,183.84 Tons of carbon dioxide (CO2), 41.3544 kg of methane (CH4) and 7.2612 kg of nitrous oxide (N2O). The CO2 emission from individual universities were in the range of 800 to 5,000 tons per year. Similarly, the CH4 was emitted in the range of 15-90 kg per year. N2O emission from all the selected universities was found very low in the range 2-16 kg per annum.  The study found that the overall rate of GHG emissions is rapidly increasing with an increase in fuel consumption resulted from high number of enrollments in selected universities. Study recommends the energy saving measures and the transition from fossil energy to renewable energy.
