GHG Reduction Project / T-VER


T-VER Project Development Process

The advantages of T-VER Project  

  1. Project documentation in Thai language
  2. The GHG Mitigation procedural is adapted in accordance with CDM’s reference,  with simplified calculation technique and and simpler monitoring system
  3. Have several Validation/Verification Bodies (VVB), not only limited to the DOE


Benefit of T-VER Project

  1. Reduction of Greenhouse Gas emission that cause global warming
  2. Increasion of sinks and reservoirs of Greenhouse Gases
  3. Revenue from carbon trading
  4. Create positive impact on coorperate image

Management approach


The 6 principles in the planning and implementation of GHG Mitigation projects including the measurement, monitoring and verification (MRV) of the GHG emission and absorbsion from the project requires the following priciples for the credibility of the carbon credit consists of;


1) RELEVENCE represents the identification of greenhouse gas emission source and reservoir; data collection and calculation are relevance to the need of target group. The estimated GHG calculation should reflect the emission and/or absorption of GHG gases; resulting from the project activity or related to project implementation.     


2) COMPLETENESS represents the estimated GHGs emission and/or absorption should base on emission and or removals occur with and without project activity. All related data regards to the measurement of GHGs emission and/or absorption should be collected completely in accordance with the criteria and methodology.

3) CONSISTENCY represents the collected data or the calculation of GHGs emission and/or absorption must follow the same principle/methodology.

4) ACCURACY represents the method used in calculation of GHGs emission and/or absorption is accurate, reliable and acceptable.

5) TRANSPARENCY represents the disclosure information on the collected or calculated GHGs emission and/or absorption must be sufficient, appropriated and can be verified.  

6) CONSERVATIVENESS represents the used of assumption, figures and process of assessment to estimate the GHGs emission and/or absorption arising within the project are not too much more than the reality. 


The assurance of T-VERs Carbon Credit credibility 

1. The implementation framework of T-VER is in accordance with ISO 14064-2 Standard

2. Validation and Verification of GHG emission Framework confonts with ISO 14064-3 Standard

3. Validation and Verification Body: VVB or VB is registered with TGO  


  1. Greenhouse Gas (GHG) is gasenous compond in the atmosphere, the natural and man-made GHG gases are those with ability to absorb infrared radiation from earth’s surface, atmosphere and cloud. 
  2. Global-warming potential (GWP) is a relative measure of how much heat a greenhouse gas traps in the atmosphere. It compares the amount of heat trapped by a certain mass of the gas in question to the amount of heat trapped by a similar mass of carbon dioxide.
  3. Source of GHG Emission is process of GHG gas is released from source into atmosphere.
  4. GHG sink and resovior are source or process of GHG gases are removed from the atmosphere and sequestrated in biosphere, geosphere or hydrosphere.
  5. Thailand Voluntary Emission Reduction or T-VER is a domestic project that is implemented by project developer under the voluntary GHG mitigation scheme; aim to reduce GHG emission in accordance with Thai standard. 
  6. Project Developer is a project implementer and/or co-partner that are responsible for the implementation of the project and/or own the project.
  7. Designated Operational Entity  (DOE) is Thailand Greenhouse Gas Management Organization (Public Organization) (TGO), with authority in registration and management of T-VER Projects.
  8. Baseline emission is the GHG emission from Business-as-Usual scenario (BAU) or in another word in the emission without the T-VER project intervention.
  9. Baseline methodology is the standard, assumption, approach and other technique that are applied in the calculation of baseline GHGs Emission of the T-VER project.
  10. Monitoring is the direct and indirect activities that project developer collect and manage data on the GHG emision between the project implementation period in continuous manner.
  11. Additionality represents the reductions in emissions that are additional to any that would occur in the absence of the project activity, according to the TGO’s procedure.
  12. Co-benefit is the gaining of other benefit in addition to the GHG mitigation i.e. the project minimizes the environmental impact; increase job opportunities and income for communities. 
  13. Leakage is a measurable emission that is attributable to the project, but which is outside of the project boundary. 
  14. Validation and Verification Body: VVB is the organization or agency that is registered by TGO to be evaluate/validate/verify project in line with the T-VER criteria.
  15. Validation is a systematic independent operation with written record on acessment of project feasibility and calculation of emission methodology in the Project Design Document (PDD) that is in accordance with the Validation Criteria of T-VER project.
  16. Verification is a systematic independent operation with written record for report appraisal on the amount of GHGs emission in accordance with the Verfication Criteria of T-VER project


Project Registration

The process

  1. Project developer submits a request together with required project documents for consideration.
  2. TGO carries out the preliminary examination of the submitted documents for consideration of document completeness as defined; and shall inform a project developer within 20 working days, counting from the submitted date. 
  3. TGO presents project to Sub-committee on GHG gases mitigation project for consideration prior to submission to the TGO’s committee board.
  4. TGO informs the result to the project developer.


Required documents upon project registration

Project developer must prepare the following documents to TGO:

  1. An application form
  2. Two copies of Project Design Document which has been validated by VVB
