What is a baseline?

The baseline for a JI project activity is defined in 9/CMP.1, Annex, Appendix B, paragraph 1 as follows:

The baseline for an Article 6 project is the scenario that reasonably represents the anthropogenic emissions by sources or anthropogenic removals by sinks of greenhouse gases that would occur in the absence of the proposed project (9/CMP.1, Annex, Appendix B, paragraph 1).

In other words, a baseline for a JI project activity is a hypothetical reference case, representing the volume of greenhouse gases that would have been emitted if the project were not implemented.  Therefore, the baseline can be used to determine:

  • whether a JI project activity is additional; and
  • the volume of additional greenhouse gas emission reductions achieved by a project activity.

Baselines must cover emissions from all gases, sectors and source categories listed in Annex A to the Kyoto Protocol that occur within the project boundary:

A baseline shall cover emissions from all gases, sectors and source categories listed in Annex A, and anthropogenic removals by sinks, within the project boundary (9/CMP.1, Annex, Appendix B, paragraph 1).
