There is nothing in the 2006 GL and UNFCCC reporting GL that forbids the use of Monte Carlo to estimate emissions. As encouraged by the IPCC Guidelines, Parties can also use national methodologies where they consider these to be better able to reflect their national situation, provided that these methodologies are consistent, transparent and well documented. Because of the potential inconsistencies resulting from just applying Monte Carlo to estimate uncertainties and not to estimate actual emissions, from our experience in the forestry sector, we highly recommend using Monte Carlo for both as resources allow/permit.
