Pollution is the action of contaminating air, water or land by harmful substances which are natural and man-made wastes. Such wastes degrade the air, water or land which reduces is quality and usage. Sources of pollutions are automobiles, increased chemical wastes, nuclear wastes and accumulation of garbage in landfills. Air pollution is one type of environmental contamination which has remained as a main problem in the society. Major contaminants include carbon dioxide (CO2), carbon monoxide (CO), sulfur dioxide (SO2), hydrocarbons (HC) and particulates. These contaminants pose critical environmental and health threats. These are not only experienced locally but internationally as well. Other parts of the globe experience worse cases than the other due to certain conditions of the environment.

Global emissions of carbon dioxide (CO2) from fossil fuels have been increasing by 2.7% annually over the past decade and are now 60% above 1990 levels, the reference year for the Kyoto Protocol. A range of different options that could help in improving the quality of the air and for mitigating climate change is considered worldwide including Carbon Capture and Storage (CCS) and Carbon Capture and Utilization (CCU). CCS, however, faces a few technical and economic barriers that it must overcome before it can be deployed large scale, one of which is that it is unprofitable. CCU, on the other hand, is profitable due to the conversion of
