 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. The term usually refers to stoves which are burning firewood, charcoal, agriculture residues or dung.<ref name="http://www.forestrynepal.org/wiki/117">http://www.forestrynepal.org/wiki/117</ref><ref name="http://www.climatetechwiki.org/technology/imcookstoves">http://www.climatetechwiki.org/technology/imcookstoves </ref>

 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/>
