The nexus of improved energy access,direct health benefits and reduced indoor air pollution canbe achieved in part through expanding access to cleancookstoves and fuels.This is of particular significance toapproximately three billion people, mainly in South Asia andSub-Saharan Africa, who still rely on solid fuels(traditional biomass and coal) for cooking and heating.Large-scale adoption and sustained use of clean cookstovesis not materializing due to a variety of context specificbarriers both on the consumer and producer/distributorsides.While financing in terms of a lack of investment andworking capital appear to be constraints for producers, lackof information, awareness, and cultural barriers dominatefor consumers and should not be underestimated.Addressingthese challenges requires a multi-pronged approach acrossfour key drivers that have been identified through reviewingsuccessful programs: awareness raising; markets andpreferences; technologies and standards; and innovative financing.
