Greenhouse gas emissions inventory & mitigation study for Karnataka

The simplest way to estimate CO2 emission from fossil fuel combustion is assuming that the carbon in the fuel is released into the atmosphere in the short or the long run. Short‐term emissions are defined within the IPCC Guidelines as those occurring within twenty years of the fuel use and are almost entirely reported in the fuel combustion module. Long‐term CO2 emissions result from the final oxidation of long‐life materials manufactured from fuel carbon and are usually emissions from waste destruction. This methodology is called the top‐down approach. In the more detailed bottom‐up approach, the computation of carbon released to the atmosphere is done at the plant level, where combustion takes place taking into account the type of fuel used. The CO2 inventory in this report is calculated using top‐down approach.
