Rapid urbanization in developing countries causes the emission of greenhouse gases. A major part of emission is released by infrastructure construction sites. construction process involves excavation, (which is a significant area of study, given that it involves changing the site by disturbing and removing vegetation. The main gases which are associated with excavation include carbon dioxide(CO2), methane(CH4) and nitrous oxide(N2O). These gases (greenhouse gases) are responsible for global warming. Nearly about 22.6% emission of co2 is due to earthwork on the construction site. Although excavation is economical in terms of delivering a flat base for raft construction, the environmental outcome of this approach needs to be examined more carefully in terms of influencing the environment. The air quality in India according to a WHO one of the polluted country in the world. In this situation, controlling and reducing pollution is an area of prime concern
