More than half of the world’s population uses solid fuels such as wood, crop waste or coal to meet their most basic energy needs for cooking, lighting, and heating. In most developing countries, these fuels are burned in the open or in rudimentary stoves. Because of high indoor concentration levels of a variety of pollutants and consequent exposure time, women and small children are at higher risk of pneumonia and other respiratory infections. Indoor air pollution is responsible for nearly half of the 2 million deaths caused every year by acute respiratory infections, and the first cause for children mortality worldwide (Bruce et al. 2011).
