WebSo basically, the IPCC divides the carbon into fossil and biogenic. Biogenic carbon indicates the carbon that originates from non-fossil or biogenic sources like wood, plants, etc because plants take up CO2 from the atmosphere. Fossil carbon are the emissions that arise from fossil sources such as coal, petroleum.
