Abstrakt: In developing nations, solid residential fuels are the major sources of primary energy for various domestic activities. To date, the emission inventory of inorganic trace gases over National Capital Territory (NCT) was prepared using either default or country-specific emission factors. In this paper, we report (for the first time) the spatial variation of emission factors (EFs) of inorganic trace gases (SO 2 , NO, NO 2 , CO, CO 2 , and CH 4 ) from the residential fuels used in slums and rural areas of NCT determined using dilution chamber in the laboratory. 147 residential fuel samples, including fuelwood, dung cake, crop residues, coal, etc., were collected at 149 NCT locations out of 675 slum clusters and 146 rural villages. The range of EF(s) of SO 2 (0.02 ± 0.01 to 0.04 ± 0.01 g kg -1 ), CH 4 (0.10 to 0.34 g kg -1 ), NO 2 (0.01 to 0.02 g kg -1 ) is lower than the CO (3.55 ± 1.72 to 6.07 ± 1.53 g kg -1 ) and CO 2 (0 to 129.45 ± 46.94 g kg -1 ). The north and north west districts of NCT are emission hotspots for CH 4 , NO, and NO 2 emissions, whereas, the southern and northern areas of NCT are for CO 2 . These citywide emission inventories (0.05° × 0.05°) of inorganic trace gases are prepared using laboratory-determined EFs and available consumption data determined by recent survey information. Among solid residential fuels, fuel wood, and dung cake are two major contributors to inorganic trace gases in NCT.
