Black Carbon – UPSC Prelims

Black Carbon (BC):
  • Black carbon(BC) is a short-lived climate pollutant.
  • It is the second-largest contributor to warming the planet after carbon dioxide(CO2).
  • Black carbon is formed through the incomplete combustion of fossil fuels, biofuel, and biomass.
  • Primary sources include emissions from diesel engines, cook stoves, wood burning and forest fires.
  • Black carbon can have significant direct and indirect impacts on the climate as it influences cloud formation and atmospheric heat absorption processes.
Other types of Carbon:
  • Blue Carbon: It refers to coastal, aquatic and marine carbon sinks held by vegetation, marine organisms, and sediments.
  • Green Carbon: It is the carbon that is stored in terrestrial ecosystems such as forests, pastures, and soils.
  • Brown Carbon: It is a light-absorbing particle in the Earth’s atmosphere that has the unique characteristics of both cooling the planet’s surface and warming its atmosphere.
