Urban areas generate 70 percent of carbon emission leading to pollution (caused by displacement of oxygen in the air) and associated impact on breathing, increase in the air pollutants, preventing earth from night time cooling (greenhouse effects - warming of ocean waters and drop in its ability to absorb carbon emission). Urban pollution has a multiplier effect on quality of life, productivity and human health with overwhelming share of seven million lives lost globally per annum. In the rapidly urbanizing world (4.5 billion currently to 6.25 billion in 2050), the carbon emission, accompanied by pollution from transport, construction, energy and
