Black carbon is present in the atmosphere predominantly due to anthropogenic activity and is the second most important cause of atmospheric warming. Natural phenomena, such as volcanic eruptions, bush fires and desert dust also significantly contribute to the climate change in different ways.
The incomplete combustion of fuels containing carbon (such as gasoline, diesel, natural gas, wood and other biomasses) results in the emission of aerosols, small particles which pollute the air and are harmful to people’s health. An important part of these emissions is soot, known by its scientific name: Black Carbon (BC). It is inert and can be transported over great distances. It also highly absorbs sunlight, which is the reason for its name – it has a very black appearance.
