Clean Development Mechanism

The Clean Development Mechanism (CDM) allows emission-reduction projects in non-Annex 1 Parties or developing countries under the UNFCCC to earn certified emission reduction (CER) credits, each equivalent to one tonne of CO2.

Designated National Authority for CDM

The National Environment Agency (NEA) is Singapore’s Designated National Authority (DNA) for CDM projects. NEA will issue a Letter of Approval (LoA) for CDM projects that meet Singapore’s sustainable development criteria. The LoA supports the registration of the project by the UNFCCC CDM Executive Board (EB). 

In the LoA application to the DNA, the project idea note (PIN) must be submitted together with the project design document (PDD) provided by the project developer to the designated operational entity (DOE) for validation. The PIN should demonstrate how the project meets Singapore’s sustainable development criteria. 

The PIN format may be downloaded here [PDF, 27.7 KB].

Singapore's sustainable development criteria

The sustainable development criteria for Singapore are as follows:

  1. Environmental sustainability
    • The project meets NEA’s Environmental Protection requirements, standards and regulations; and
    • The project produces real and measurable reductions in GHG emissions.
  2. Economic sustainability
    • The project utilises more efficient and/or environment-friendly technology than common industrial practice.
  3. Social sustainability
    • The project helps improve the quality of life by creating opportunities for jobs, job enhancement, etc.

Prior consideration

Project participants implementing CDM project activities, including programmatic CDM, commencing on or after 2 August 2008 must inform the DNA and the UNFCCC Secretariat in writing of the commencement of the project activity, and of their intention to seek CDM status, using a standardised form. 

The CDM EB takes the issue of prior consideration of the CDM as a major element in assessing that the CDM benefits were considered necessary in the decision to carry out the project as a CDM project activity. 

The form may be downloaded from the UNFCCC website here.
