What is verification?

Verification is defined in 3/CMP.1, Annex, paragraph 61 as follows:

Verification is the periodic independent review and ex post determination by the designated operational entity of the monitored reductions in anthropogenic emissions by sources of greenhouse gases that have occurred as a result of a registered CDM project activity during the verification period (3/CMP.1, Annex, paragraph 61; previously 17/CP.7, Annex, paragraph 61).

Essentially, verification is the process of confirming the authenticity of reductions in greenhouse gas emissions by a CDM project over a defined period of time (a verification period). In order to do this, a CDM project's emission reductions are monitored and the monitoring data for a verification period is reviewed and assessed.

In brief, the key elements of verification are:

  • a periodic independent review and ex post determination;
  • of reductions greenhouse gas emissions by sources which have been monitored;
  • that is performed by an independent designated operational entity (DOE).
