The Nordic Council of Ministers has set up the Nordic COP 15 Group to help achieve a successful outcome in the climate change negotiations at COP 15 in Copenhagen in December 2009. The Nordic COP 15 Group have identified key elements in the negotiations where efforts are needed to ensure a good outcome, i.e. adaptation to climate change, technolo-gy transfer, legal issues, sinks and deforestation. This report explore ways to adjust the current accounting rules on sinks into rules that would create better incen-tives for actively managing lands, in order to decrease the emission of greenhouse gases to the atmosphere and/ or to remove greenhouse gases from the atmosphere. Different proposals for the treatment of the LULUCF-sector (Land Use, Land Use Change and Forestry sector) are compared and analysed.
