Abstract
Budget estimate for carbonaceous aerosols including black carbon (BC) and organic carbon, emitted from the combustion of various fuels, is very important for regional climate studies. Emission factors for carbonaceous aerosols from bio-fuels and soft coke were determined in a controlled combustion study. The emission factors thus obtained along with those available for other fossil fuels consumed in different sectors have been applied to assess the budget for carbonaceous aerosols from India. Preliminary calculations give a range of 1.6–1.8 Tg of carbonaceous aerosols that include 0.4–1.4 Tg of BC. A major (∼80%) portion of carbonaceous aerosols emitted from India is found to originate from the use of biomass for energy as 70–80% of energy requirement in rural India is met by combustion of traditional bio-fuels.
