 Black carbon, BC, is a particulate pollutant that is produced by burning fossil fuels and biomass. It is a major contributor to global warming because it absorbs sunlight and increases the Earth's temperature. Additionally, BC can have adverse effects on human health, including respiratory illnesses and cardiovascular disease. This paper reviews the emission factors, Fs, of major anthropogenic sources of BC, including traffic, residential combustion, and energy production. The authors found that BC emissions from gasoline vehicles are higher for those with direct fuel injection compared to those with poor fuel injection, suggesting a possible increase in gasoline vehicle emissions over time. For ships, larger engines had lower BC emissions per unit of fuel consumed, while smaller engines had higher emissions. Finally, the authors noted that there is a lack of data regarding the emissions of large-scale energy production, which could lead to underestimates of the global radiative-forcing potential of anthropogenic BC emissions.
