The city of Dhaka was chosen for this assessment due to the current ongoing project Bangladesh Air Pollution Management (BAPMAN), which concentrates mostly on the capital city Dhaka. The Greenhouse Gas and Air Pollution Interactions and Synergies model (GAINS) was used to performed this top-down assessment due to the models integrated assessment approach of capturing interactions between air pollution control and economic development, as well as its focus on presenting cost effective pollution control strategies. Results from the GAINS model assessment for Dhaka shows that for 2010 the total PM2.5 emissions were 35000 tons/year, and the total PM10 emissions were 45000 tons/year. The top sectors making up the PM emissions included Industry and Residential sectors, where the specific sub-sectors were brick/cement production and residential cooking respectively; the top activities making up the emissions were 'no fuel use' and 'fuelwood direct'. GAINS estimates that the top 3 technical control measures available for PM can eliminate approximately 1/3 of the PM emissions at a cost of .65 MEuro/year. GAINS results also shows that for Dhaka in 2010 the total SO2 emissions were 34000 tons/year, dominated by the Industrial sector, made up of the sub-sectors of new power plants and industrial combustion; top activities contributing to these emissions are hard coal and natural gas. NOX emissions for Dhaka in 2010 were 30000 tons/year, dominated by the Industrial and Transport sectors, made up of the industrial combustion/power plant and light/heavy duty sub-sectors respectively; top activities contributing to these emissions include natural gas, gasoline, and medium distillates. GHG emissions for Dhaka in 2010 exceeded 23 million tons/year, dominated by the Industrial and Agricultural sectors, comprising of the industrial combustion and new power plant sub-sectors; top activities contributing to these emissions include natural gas and hard coal.
