The California Climate Action Registry utilizes a standardized approach for the verification process to promote completeness, consistency, accuracy, relevancy and transparency of emissions data. Activities for each specific verification will differ based on the length and complexity of a participant’s Emission Report, but the verification process will include at least the following steps:


  • Case by case evaluation of the potential for Conflict of Interest
  • Scoping and planning a participant’s verification activities
  • Conducting verification activities
    • Identifying emissions sources
    • Reviewing methodologies and management systems
    • Verifying emission estimates
  • Verification Report and Verification Opinion
  • Submission of participant-authorized Verification Opinion and Verification Activities to the Registry


Upon completion of the above steps, the California Registry will also review the data before accepting a participants verified Emission Report into its emissions database. This process is repeated every year of an organizations participation in the California Registry.
