This paper elaborates on the issue of adjustments to national greenhouse gas (GHG) inventories and projections, in particular to those related to temperature fluctuations. In preparing this paper, the secretariat compiled information on adjustments submitted by Parties in the first and second national communications; in total, seven Parties provided unadjusted and adjusted data on GHG emission inventories and/or projections. It also analysed the limitations of various methods and their implications. Detailed analyses may be found in technical paper TP/1997/2
