the past 4 months, which has terrible indoor air pollution in most low income homes, was 6000 micrograms per cubic metre. That is 20 times the exposure in Beijing on a bad ‘orange alert’ day. The exposure of a Kenyan cook is

and can be burned very cleanly (test, don’t assume). It can be produced at scale and distributed at lower cost and at greater convenience than LPG. So….just do it.

<p><span lang="EN-US" style="font-family:"Calibri",sans-serif">Woodfuel releases carbon fumes into the air, adding to the carbon footprint and global warming. This has resulted in global climatic change, which is also being witnessed in Kenya in the form of
higher temperatures, prolonged droughts and dry spells.<o:p></o:p></span></p>
<p><span lang="EN-US" style="font-family:"Calibri",sans-serif">Though new to the local market, ethanol has gained wide use in Mozambique because it is clean and efficient, comparable to LPG. CleanStar Ventures has conducted market research primarily in urban
households that confirms the convenience and safety of ethanol. <o:p></o:p></span></p>
<p><span lang="EN-US" style="font-family:"Calibri",sans-serif">The Kenya Forestry Service (KFS), the Kenya Forestry Research Institute (Kefri), and ICRAF, among others, are working with farmers on managing trees for woodfuel. They promote the harvesting of
mature stems, growing of acacia trees for charcoal and managing trees in drylands.<o:p></o:p></span></p>
