THE METHODOLOGY

Criteria alone are not enough to undertake meaningful assessment. The Carbon Credit Quality Initiative's methodology is designed to provide a deep assessment of a carbon credit and indicate on a scale of 1-5 the confidence or likelihood that the carbon credit meets each criterion or quality objective.

5 Very high confidence or likelihood that the assessment subject meets the criterion or quality objective.
4 High confidence or likelihood that the assessment subject meets the criterion or quality objective.
3 Moderate confidence or likelihood that the assessment subject meets the criterion or quality objective.
2 Low confidence or likelihood that the assessment subject meets the criterion or quality objective.
1 Very low confidence or likelihood that the assessment subject meets the criterion or quality objective.

Applying the methodology requires a thorough understanding of carbon crediting. The methodology is written for use by carbon credit experts, rather than a broader, non-technical audience. We recommend that the methodology be applied by independent experts who do not have financial interests in specific evaluation results.

Assessing the quality of carbon credits is methodologically challenging and often requires difficult judgments. The approaches presented in the methodology are the authors' judgment of what quality features matter and how these could be practically assessed and weighed. The methodology was developed based on a literature review, the authors' own research, a 5-week consultation and feedback from various experts and stakeholders.

Version history
  • An initial version of the methodology that was used for piloting was published in August 2021 (version 0.1)
  • Based on the findings from the pilot application, version 1.0 of the methodology was released in November 2021
The methodology will be further improved over time
