 Cookstoves are commonly called “improved” if they are more efficient, emit less emissions or are safer than the traditional cook stoves or three-stone-fires.

This enhances the temperature of the fire with the following consequences: faster water boiling, fuel use reduction, and decreases in CO and PM.

 It is difficult to get regional or even global data on improved stoves sales or use. The [http://cleancookstoves.org/|Global Alliance for Clean Cookstoves] is the only stakeholder, which is collecting such data on a global scale from her member organizations and companies.<br/>In 2013, 14, 3 million stoves were disseminated by partners of the Global Alliance for Clean Cookstoves, including LPG stoves, biogas stoves, etc. Almost one third of them in Africa, over 60% in Asia and 6% in Latin America. Two thirds of the distributed stoves were portable.<ref name="Global Alliance for Clean Cookstoves: Results Report 2013. http://cleancookstoves.org/binary-data/RESOURCE/file/000/000/285-1.pdf"> Global Alliance for Clean Cookstoves: Results Report 2013. http://cleancookstoves.org/binary-data/RESOURCE/file/000/000/285-1.pdf</ref> In 2014, 20 million stoves and fuels were reported, out of which 12 mio. were classified as clean and/or efficient.

 However, be aware that not all so-called “improved“ stoves are really saving energy or emit less harmful smokes. Sometimes, stoves that are designed to be more efficient are in reality less efficient than the prevailing technology or emit higher levels of emissions. Only proper stove testing not only in laboratories but in existent kitchens with real users (field test) can show how improved an “improved” stove really is.<ref name="http://www.scientificamerican.com/article/improved-cookstoves-little-reduce-harmful-indoor-emissions/">http://www.scientificamerican.com/article/improved-cookstoves-little-reduce-harmful-indoor-emissions/</ref>&nbsp;Furthermore, over the years and with constant use, ICS can get weaker in their performance by losing efficiency and higher emissions due to bad maintenance, material fatigue and wrong usage.<br/>

 *'''Forced air stoves''' have a fan powered either by a battery, an external source of electricity, or a thermoelectric generator. This fan blows high velocity, low volume jets of air into the combustion chamber that mix fuel, air and flame. Mixing results in more complete combustion of the fuel and dramatically reduces pollution.<ref name="Global Alliance for Clean Cookstoves, http://cleancookstoves.org/technology-and-fuels/stoves/">Global Alliance for Clean Cookstoves, http://cleancookstoves.org/technology-and-fuels/stoves/ </ref><ref name="http://www.ewb-usa.org/files/2015/05/TestResultsCookstovePerformance.pdf">http://www.ewb-usa.org/files/2015/05/TestResultsCookstovePerformance.pdf </ref>
 *'''[[Gasifier Stoves|Gasifier stoves]]'''&nbsp;force the gases and smoke that result from incomplete combustion of fuels such as biomass back into the cookstove's flame, where the heat of the flame then continues to combust the particles in the smoke until almost complete combustion has occurred, reducing emissions. Typical gasifier stoves are known as Top Lit Updraft (TLUD) stoves because some fuel is lit on top of the stove, forcing combustible products to pass through the flame front before being emitted into the air. Gasifier stoves can also include a fan, to improve mixing of flame, gas, and smoke and to reduce emissions.<ref name="http://carbonfinanceforcookstoves.org/about-cookstoves/cookstoves-and-fuels/">http://carbonfinanceforcookstoves.org/about-cookstoves/cookstoves-and-fuels/ </ref>
