 The extraction, transportation and combustion of biomass releases a significant amount of carbon into the atmosphere. This carbon is added to the atmosphere and it takes time before it is balanced by the ecosystem. According to a report by IPCC on renewable energy sources and climate change mitigation (2011), ''it can take decades, even centuries, before ecosystems; in particular forests can recapture the carbon that has been released during biomass combustion'' . This creates a "'''carbon debt'''" in the atmosphere.

 To understand the net effect of black carbon on atmospheric warming, it is important to take into account the following points:
-*Black carbon is not emitted alone but rather with other particles such as sulfur dioxide (SO2) , nitrogen oxides (NOx) and organic carbon. Some of these particles have a cooling effect on the climate. Therefore to calculate the net effect of black carbon, the cooling effect of co-emiited pollutants has to be offset.<ref name="http://www3.epa.gov/blackcarbon/2012report/Chapter2.pdf">http://www3.epa.gov/blackcarbon/2012report/Chapter2.pdf</ref>

 According to a computer simulated model by Prof Jacobson,&nbsp;the director of Stanford’s Atmosphere/Energy Program and a senior fellow at the Stanford Woods Institute for the Environment and the Precourt Institute for Energy, "the sum of warming caused by all anthropogenic greenhouse gases – CO2, methane, nitrous oxide, chlorofluorocarbons and some others – plus the warming caused by black and brown carbon will yield a planetary warming effect of 2 degrees Celsius over the 20-year period. But light-colored particles – white and gray particles primarily – reflect sunlight and enhance cloudiness, causing more light to reflect.''''The cooling effect of these light-colored particles amounts to slightly more than 1 degree celcisu and thus the''''&nbsp;total net warming gain is 0.9 C or so and biomass accounts for about 0.4 degree celcius''.<ref name="https://engineering.stanford.edu/print/node/38216"> https://engineering.stanford.edu/print/node/38216</ref>
-Jacobson’s model also tracks the impact of the direct heat produced by combusting biomass. According to the model, the direct heat generated by burning biomass is significant and contributes to cloud evaporation by decreasing relative humidity and determined that 7 percent of the total net warming is caused by biomass burning – that is, 7 percent of the 0.4 C net warming gain – can be attributed to the direct heat caused by the fires.”<ref name="https://engineering.stanford.edu/print/node/38216"> https://engineering.stanford.edu/print/node/38216</ref>
