2.6 Registry and avoidance of double counting


  • Projects and carbon units shall only appear on one carbon registry - the UK Land Carbon Registry
  • For group validation/ verification, the group and its constituent projects shall be entered on the registry as a 'master project' and 'subprojects' respectively
  • All projects, project documentation, carbon units, assignments and retirements shall be visible in the 'public view' of the UK Land Carbon Registry
  • Upon validation, Pending Issuance Units shall be listed for all carbon units in the project, except for a limited number of projects where predicting the carbon sequestration is more challenging. Verified Woodland Carbon Units shall be issued once the actual amount sequestered is known. This includes:
    • Natural regeneration projects which are very large-scale, or where there is little or no ‘baseline’ evidence of seedlings regenerating
    • Woodland creation projects which are planting a species where there is less information about sequestration rates and no ‘carbon model’ is mapped in the Woodland Carbon Code Carbon Calculator.
  • Any Pending Issuance Units sold in advance of verification shall either be transferred to the relevant buyer's account or 'assigned' to that buyer
  • At each verification, Pending Issuance Units for that vintage shall be cancelled and the verified number of Woodland Carbon units issued
  • Prior to using Woodland Carbon Units in any reports, they shall be 'retired' from the UK Land Carbon Registry
  • Projects shall not accept any tree donations or other sponsorship where this creates a double claim between the Woodland Carbon Code and the donation regarding the carbon benefit
  • Project developers shall comply with the registry rules of use. 


The UK Land Carbon Registry is managed by S&P Global on behalf of the Woodland Carbon Code and the Peatland Code.
