The other day I noticed that Norway& #39;s latest submission to the UNFCCC had a significant revision of LULUCF emissions since the last report. Turns out this is completely normal. Here are the US reports starting in 2003, with revisions spanning hundreds of millions of tonnes.
Russia& #39;s revisions of LULUCF, starting from their first submission to the UNFCCC in 2006.
Germany& #39;s revisions of LULUCF, starting from their first submission to the UNFCCC in 2003. Its base year (1990) emissions have curiously jumped from -29 Mt in last year& #39;s submission to +25 Mt in this year& #39;s.
Norway& #39;s revisions of LULUCF, starting from their first submission to the UNFCCC in 2003.
Sweden& #39;s revisions of LULUCF, starting from their first submission to the UNFCCC in 2003.
Canada& #39;s revisions of LULUCF, starting from their first submission to the UNFCCC in 2003.
These are developed countries, updating activity data and improving (including finding mistakes in) their methodology, leading to đ”đđŽđČ revisions. With all the data and information they have to hand, still enormous uncertainty. What of global land-use change emissions?
