The EDIP method's criteria for which substances contribute to global warming generally follow the IPCC's recommendation of excluding indirect contributions to the greenhouse effect , i.e. contributions attributable to a gas affecting the atmospheric lives of other greenhouse gases already present. The indirect effects are difficult to model, and the IPCC is therefore refraining for the time being from quantifying indirect contributions with the exception of contributions from the gas methane (CH4). The EDIP however, goes further than the IPCC's recommendation in including the contribution from organic compounds which is due to their inevitable degradation to CO2 in the atmosphere. 2
