Fig. 2: Aggregate per-capita emission rates for typical sanitation containment systems in Kampala.

Annual per-capita emissions of methane (black) and nitrous oxide (grey) expressed in kgCO2 equivalent from containers (pits and tanks) in Kampala under observed operating conditions. Emissions rates were calculated using the IPCC method. Methane-correction factors and emissions factors were calculated using information about the extent of aerobic and anaerobic conditions observed inside containers by Nakagiri et al.21.
