Variation of manufacturing cost of brick largely depends on the brick kiln as well as the manufacturing process. The effect of CO2 emission from brick manufacturing factories and the CO2 emission reduction is now global issue, and minimizing its impact by precautionary and preventive measures is now a challenge for the world leaders. As a third world country Bangladesh is not out of it. Flood, tropical cyclones, droughts, storm surges are most likely to become frequent and severe in coming years here. Globally, using fossil fuels, even in Bangladesh, to meet energy demand not only counteracts the need to prevent climate change but also has negative environmental effects locally. Brick manufacturing factories are emitting CO2 in ways by producing CO2 in fuel utilization, More than 6000 traditional and 2000 alternate brick works in average energy and fuel consumption, to evaluate effect of brick Kiln on Bangladesh are heavily polluting, and they are major reasons for air pollution in the country. Objective of this research work is to compare traditional manufacturing process with alternative processes those are energy efficient and utilize less coal, CO2 emission from brick manufacturing factories. (Burning Wood emits 1.25-3.00 times as much more CO2 than coal as per emission data from environment reports for proposed (Russel, Palmer), to recommend CO2 reduction process for brick manufacturing factories, to evaluate impact of CO2 and dust on health of the workers and the road side people. Bangladesh produces 4% of the total world brick production and is approximately 50 billion per year. As per the estimation in this study will contribute approximately 30.0 million tons CO2 emission per year if all bricks are produced by Fixed Chimney Kiln (FCK) & also 50% reduction is possible by using alternate kiln such as Zigzag kiln.
