The blog by Maria Sarraf, Lead Environmental Economist, World Bank Headquarters, comes with new evidence on brick manufacturing industries of Bangladesh which is a prime contributor to air pollution in Bangladesh capital Dhaka and surrounding districts. It turns out that brick making is a booming sector as the economy of the country witnesses a robust growth in the recent time. What is needed most is to switch from traditional brick making to energy efficient production system where emissions of flue gas and black carbon will be less. The co-benefits of this transformation will be reduced emissions of black carbon, which is also known as climate pollutant or SLCP. At this hour a revolving fund with World Bank support could be set up to facilitate brick entrepreneurs to transform their kilns either to less polluting ones using modern brick making technology or retrofit the existing kilns to energy efficient ones. The Bank also may come forward to assist Bangladesh to popularize non-fired brick in a big way. At this hour brick manufacturing act is being reviewed by the government. In all likelihood enforcement of laws will not be there in a full steam once the law comes into effect.
