This technical paper was prepared based on submissions by Parties and on the work by the clean development mechanism (CDM) Executive Board. It presents options on the following issues: further clarifications on definitions of eligible small-scale afforestation and reforestation project activities, including on the calculation of project size; possible categories of projects for which methodologies can be simplified; draft simplified modalities and procedures for small-scale afforestation and reforestation project activities; a simplified project design document; the structure of an indicative simplified baseline and monitoring methodologies for selected types of small-scale afforestation and reforestation project activities under the CDM; and criteria for determining the occurrence of debundling of projects.
