Starting date (CPA)
The definition of "starting date" for a component project activity (CPA) is set out in the CDM Glossary of Terms as follows:
The starting date of a CDM programme activity is the earliest date at which either the implementation or construction or real action of a programme activity begins (CDM Glossary of Terms Version 07).
This definition was further discussed and clarified at EB 41:
In light of the above definition, the start date shall be considered to be the date on which the project participant has committed to expenditures related to the implementation or related to the construction of the project activity. This, for example, can be the date on which contracts have been signed for equipment or construction/operation services required for the project activity. Minor pre-project expenses, e.g. the contracting of services /payment of fees for feasibility studies or preliminary surveys, should not be considered in the determination of the start date as they do not necessarily indicate the commencement of implementation of the project. For those project activities which do not require construction or significant pre-project implementation (e.g. light bulb replacement) the start date is to be considered the date when real action occurs. In the context of the above definition, pre-project planning is not considered “real action”.
The Executive Board further noted that there may be circumstances in which an investment decision is taken and the project activity implementation is subsequently ceased. If such project activities are restarted due to consideration of the benefits of the CDM the cessation of project implementation must be demonstrated by means of credible evidence such as cancellation of contracts or revocation of government permits. Any investment analysis used to demonstrate additionality shall comply with the requirements of paragraph 7 of the "Guidance on the assessment of investment analysis" (EB 41, paragraph 67).
Project proponents can choose the starting date of CPAs. However, the starting date cannot be before the commencement of validation of the programme of activities:
The starting date of the CPA cannot be prior to the commencement of validation of the programme of activities i.e. the date on which the CDM-POADD is first published for global stakeholder consultation. (CDM Glossary of Terms, Version 05)
The start date of the crediting period of a CPA shall be on or after:
(a) The date of registration of the PoA, if the corresponding CPA-DD is submitted together with the request for registration;
(b) The date of approval of the corresponding specific case CPA-DD is submitted for approval by the Board;
(c) The date when the CPA was included in accordance with the Project cycle procedure. (EB 70, Annex 2, paragraph 163)
