In tackling the problem of household air pollution and reducing the impacts associated with emissions of black carbon, ClimateCare has promoted the sale of Safi ethanol cookers.
Ethanol Stoves are rated amongst the best cook stoves by the Global Alliance for Clean Cook Stoves in terms of the stove performance, including efficiency, total emissions, indoor emissions and safety. The use of ethanol stoves by households in Kibera contributes to both health and climate impacts. ClimateCare has commissioned Climate Solutions Consulting to undertake a study to assess the impacts of using ethanol cookers in households in Kibera. The first part of the study focused on black carbon emission factor measurement for ethanol, charcoal and kerosene stoves in Kibera, Kenya. The measurements for this study were taken in 30 households using ethanol, charcoal and kerosene stoves.
The study revealed that the Safi ethanol cooker reduced the climate impact associated with black and organic carbon by 91% compared to the kerosene stove and by 83% compared to the charcoal stove. Emission factors for carbon monoxide, particulate matter and black carbon were of a magnitude higher for charcoal stoves than for the kerosene and the ethanol stoves. The difference in particulate matter emissions
between charcoal stoves and ethanol stoves is wide but not so between the kerosene stove and the ethanol stove. It is noted therefore that the greatest health impact is expected to be for households switching from charcoal to ethanol.
It is expected that the Black Carbon emission factors established during this study will be used by Green Development to quantify the overall black carbon emissions reductions (savings) in their CDM carbon offset Programme of Activity which the Ethanol Cookers Project is a Component Project Activity (CPA). Green Development is a certified carbon asset developer who is the Coordinating Managing Entity (CME) for the “Programme of Activities (PoA) for the Reduction of emissions from non-renewable fuel from cooking at household level.”
This Programme is located in Sub Saharan Africa and aims at promoting clean renewable fuels for cooking (ethanol and biogas) and water purification technologies.
