Black carbon, that often causes glaciers to recede, is emitted in the atmosphere due to incomplete combustion of fossil fuels in motor vehicles and aircraft exhausts, bio-fuel and biomass. Both, India and China are the largest emitters of black carbon in the world, with emissions of up to 25-35 per cent.
Who is the largest carbon emitter?

How is black carbon generated?
Black carbon consists of pure carbon in several linked forms. It is formed through the incomplete combustion of fossil fuels, biofuel, and biomass, and is one of the main types of particle in both anthropogenic and naturally occurring soot. Black carbon causes human morbidity and premature mortality.
How are humans producing black carbon?
BC is produced both naturally and by human activities as a result of the incomplete combustion of fossil fuels, biofuels, and biomass. Primary sources include emissions from diesel engines, cook stoves, wood burning and forest fires.

Which country has the lowest carbon footprint in the world?
You have probably never heard of Tuvalu before, and that is a big part of the reason why it has the lowest carbon footprint on the planet. Their current carbon footprint rests at zero MtCO₂, and they plan to continue this trend by doing away with fossil fuels altogether.
What is black carbon Drishti IAS?
Black Carbon is a short-lived pollutant that is the second-largest contributor to warming the planet behind carbon dioxide (CO2).
Which of the following has the highest global warming potential?
Carbon dioxide is used as the base for all the calculations, so its global warming potential is 1. 2 The higher the GWP, the more heat the specific gas can keep in the atmosphere.
Table 1: High Global Warming Potential Gases.
| Global Warming Potentials of Greenhouse Gases | ||
|---|---|---|
| SF6 | 16300 | 22800 |
Is carbon black and black carbon the same?
Despite similar names, carbon black should not be confused with black carbon. Carbon black is distinguished by a high EC content and well-controlled properties. Black carbon particles are characterized by their heterogenous properties. Carbon black is not a model particle representative of engineered nanomaterials.
