This note includes a synthesis of the methods used by Parties included in Annex I to the Convention (Annex I Parties) to estimate and report greenhouse gas emissions and removals from the land-use change and forestry (LUCF) sector before the adoption of decision 13/CP.9. and the application of the Intergovernmental Panel on Climate Change (IPCC) good practice guidance for land use, land-use change and forestry (LULUCF). This analysis focuses on category 5.A (Changes in forest and other woody biomass stocks) of the common reporting format because most of the data belong to this category. The data indicate that many Annex I Parties have had problems in estimating emissions and removals in these categories because, for example, of difficulties in applying the Revised 1996 IPCC guidelines for national greenhouse gas inventories to national circumstances. The paper also contains information on methods used to develop projections. Although the application of IPCC good practice guidance for LULUCF is expected to improve inventory data, more focused reviews could help improve inventories of Parties having LULUCF as key sector. The exchange of information on methods used for projections is also important to facilitate improvements. With the adoption of decision 13/CP.9, reporting is expected to improve. This note identifies future actions that may facilitate the transition to the new reporting system, taking into account the problems some Parties have experienced with the reporting of emissions and removals from the LUCF sector.
