Table 3 Household (HH) level emissions from burning fuelwood, using LPG and electricity and net emission reduction potentials of biogas from waste and improved cooking stoves (ICS) in lower-middle (LM) and upper-middle (UM) income groups of Anowara Upazila, Chattogram. ± represents the standard error of the mean. Different letters within a column indicate a significant difference at p ≤ 0.05 between the income groups for the variables.
