What is bundling?
Bringing together of several small-scale CDM project activities, to form a single CDM project activity or portfolio without the loss of distinctive characteristics of each project activity (EB 21, Annex 21, paragraph 3).
However, the Conference of the Parties serving as the meeting of the Parties (COP/MOP) has confirmed that large-scale projects are also eligible to be bundled:
Recognizes that large-scale project activities under the clean development mechanism can be bundled if they are validated and registered as one clean development mechanism project activity and invites the Executive Board to provide further clarification if needed (7/CMP.1, paragraph 21).
The advantage of bundling is that bundled projects can obtain a single validation report and a single certification report for the entire bundle, which streamlines these processes for project participants.
