A new report by the World Health Organization (WHO) says despite more than a decade of work to reduce domestic air pollution sources, progress toward universal access to clean cooking fuels remains far too slow. Almost 3.1 billion people still rely on polluting, inefficient energy systems such as biomass, coal or kerosene to meet their daily cooking needs – a number virtually unchanged over the past decade. And too many households still depend on polluting fuels and devices for heating and lighting – particularly kerosene. This global report provides new data on the still-pervasive use of polluting fuels for home cooking, lighting and heating, as well as an in-depth look at the impacts on women and children. For instance, almost half of all African households across the 25 countries surveyed rely primarily upon highly-polluting kerosene lamps, while about 30% of households surveyed in South-East Asia use kerosene lights. Conversely, solar powered lights still have very low uptake (1% or less) in many countries.
