What is a methodology?

There are two types of methodologies for small-scale afforestation and reforestation (SSC A/R) projects – baseline methodologies and monitoring methodologies.

Baseline methodologies in the context of SSC A/R projects are defined as follows:

A methodology is an application of a baseline approach. The most likely baseline scenario of the small-scale A/R CDM project activity is considered to be the land-use prior to the implementation of the project activity… (Glossary of CDM Terms, Version 03).

Monitoring methodologies in the context of SSC A/R projects is defined as follows:

A monitoring methodology refers to the method used by project participants for the collection and archiving of all relevant data necessary for the implementation of the monitoring plan. A "simplified baseline and monitoring methodologies for selected small-scale afforestation and reforestation CDM project activity categories" is publicly available on the UNFCCC website (cdm.unfccc.int). Project participants may use the methodology for project categories, which fall under the applicability conditions of the methodology (Glossary of CDM Terms, Version 03).

Therefore, a monitoring methodology is the means by which to calculate the net anthropogenic GHG removals by sinks achieved by the A/R project, taking into account any emissions from sources within the project boundary. A monitoring methodology sets out how project proponents should develop and implement a monitoring plan for a project, in order to gather the data required to calculate emission removals generated by the project.

Simplified baseline and monitoring methodologies have been developed for the 4 eligible SSC A/R project types in order to reduce project costs:

  • Grasslands to forest (AR-AMS0001)
  • Croplands to forest (AR-AMS0001)
  • Settlement to forest (AR-AMS0002)
  • Wetlands to forest (AR-AMS0003)

Project participants may use the simplified methodology applicable to their project:

Project participants may use the simplified baseline and monitoring methodologies specified in appendix B (6/CMP.1, Annex, paragraph 6).

Project proponents should select and apply the methodology from this set that is appropriate to the proposed project activity or, if none are appropriate, propose alternative baseline and monitoring methodologies for the project to the Executive Board:

Simplified baseline and monitoring methodologies may be developed for four types of small-scale afforestation and reforestation project activities under the CDM, as presented in the list in appendix B. This list shall not preclude other types of small-scale afforestation and reforestation project activities under the CDM. If a proposed small-scale afforestation and reforestation project activities under the CDM does not fall into any of the types in appendix B, the project participants may submit a request to the Executive Board of the CDM (hereinafter referred to as the Executive Board) for approval of a simplified baseline and/or monitoring plan, bearing in mind provisions in paragraph 8 below (6/CMP.1, Annex, paragraph 2).

This chapter explains the process for the development, submission, approval and revision of a new methodology.
