Household air pollution resulting from cooking with biomass kills three times as many people around the world as malaria, HIV/AIDS and TB combined. In India alone 875,000 deaths occur every year due to Indoor Air Pollution.
Project Surya is working with local energy entrepreneurs to distribute clean cookstoves, at a subsidised cost. In addition, it pays the users based on usage and the resulting savings in carbon emissions.
