Recent estimations show that residential solid fuel combustion accounts for 25% of global black carbon (BC) emissions (Lamarque et al., 2010). Thus, the control of these emissions through the implementation of cleaner cooking technologies could be crucial for climate change mitigation (Venkataraman et al., 2005). However, BC emission factors for biofuel cooking stoves have been poorly estimated due to the wide distribution and remote location of the stoves and the relatively complex existing assessment methods. This work presents results on BC emission factors (EF) estimation from combustion of biomass cooking
systems in Western Africa (in Senegal). Three stones fire
(traditional stove), Noflaye Jegg (rocket stove), Jambaar
bois (ceramic improved stove) and a gasifier were
analysed under laboratory conditions at the Centre de
Recherche sur les Energies Renouvelables (CERER) in
Dakar. Two types of fuels (wood species) were tested:
Casuarina Equisetifolia (Filao) and Cordyla Pinnata
(Dimb). Three replicates of the standardized Water
Boiling Test with two phases (cold start and simmer)
were conducted at the laboratory to test each cooking
system. PM2.5 emissions were collected on quartz fibre
filters, and BC content was subsequently analysed using
three analytical methods: i) Nexleaf system, in which a
photograph of the filter is compared with a calibrated
reference scale; ii) the EEL43 Smoke Stain
Reflectometer; and iii) the Sunset Laboratory OCEC
Analyzer. The two first were compared with the third
one, considered the internal reference
