Indoor air pollution is responsible for over 1.6 million annual deaths and 2.7 percent of the global burden of disease (in Disability-Adjusted Life Years or DALYs). A major source of indoor air pollution in developing countries is the burning of solid fuels such as biomass (animal dung, wood, crop residues) and coal for heating and cooking. It has been estimated that nearly half the world’s population still uses solid fuels for household cooking and space heating.  The impact of indoor air pollution on human health varies considerably according to the level of development –it is the poorest in developing countries who suffer a greater proportion of ill health and premature death from this risk factor. Young children and women are disproportionately affected by indoor air pollution, with exposure levels exceeding international health-based guidelines by 20 times or more. Children under five years of age account for more than 50 percent of deaths due to indoor solid fuel use.  Analytical work and research studies within the Bank is looking at low-cost interventions such as improved cookstoves, cleaner fuels, better stove placement and ventilation, behavioral modification and other strategies for reducing exposures to smoke. Through valuation studies, attempts are being made in several countries to estimate health costs attributed to indoor air pollution, as well as to undertake cost-benefit analysis to assess and compare different interventions.  à Analytical Studies, Research and Toolkits à Bank Lending  à For more information please go to Partners and Publications pages  |
