The Conference of the Parties, by its decision 2/CP.13, requested the Subsidiary Body for Scientific and Technological Advice (SBSTA) to undertake a programme of work on methodological issues related to a range of policy approaches and positive incentives for reducing emissions from deforestation and forest degradation in developing countries. As part of this programme of work, Parties were invited to submit to the secretariat, by 21 March 2008, their views on how to address outstanding methodological issues including, inter alia, assessments of changes in forest cover and associated carbon stocks and greenhouse gas emissions; incremental changes due to sustainable management of the forest; demonstration of reductions in emissions from deforestation, including reference emission levels; estimation and demonstration of reductions in emissions from forest degradation; implications of national and subnational approaches, including displacement of emissions; options for assessing the effectiveness of actions in relation to paragraphs 1, 2, 3 and 5 of decision 2/CP.13 and criteria for evaluating actions. The SBSTA requested the secretariat to compile these submissions for its consideration at its twenty-eighth session. The secretariat has received 14 such submissions. In accordance with the procedure for miscellaneous documents, these submissions are attached and reproduced in the language in which they were received and without formal editing
