A carbon-removal statement needs an evidence trail that matches the claim being made. A project description alone does not establish the quantity, timing or ownership of a claimed removal. This review records whether key evidence is available, missing or unknown and turns the gaps into follow-up actions. It is a preparation tool for checking a claim, not a certificate or an assessment of environmental integrity.
Carbon-removal claim evidence review
Record which evidence is available for a stated environmental claim.
Evidence completeness is not certification or a conclusion that a claim complies with a reporting standard.
What the result shows
Each evidence item has three possible states: available, missing or unknown. Available means that you can locate supporting material, rather than simply remembering that a process exists. Missing and unknown items become follow-up actions. The count describes the evidence statuses you entered; it does not measure the quality of the documents or establish a legal, technical or commercial conclusion about the underlying case.
Prepare the information for this review
The labels in the tool describe the measurement or record needed for each input. The following checks help keep the entered information consistent with the case you intend to review.
- Claim under review: Provide enough detail for another person to understand the point without searching through unrelated correspondence. Separate confirmed information from questions that still need an answer, and retain useful source references.
- The claim boundary is defined: Specify the product, site or organisation covered.
- The reporting period is stated: State the start and end of the measurement period.
- The emissions inventory is documented: Obtain the inventory and its scope.
- Removals are quantified separately: Separate atmospheric removals from avoided emissions.
- Verification evidence is available: Obtain the verification report and its scope.
- Storage durability and reversal treatment are explained: Obtain the storage and reversal methodology.
Check the result against the source records
Evidence completeness is not certification or a conclusion that a claim complies with a reporting standard.
Start with one case whose inputs you can trace back to the original records. Run the tool and compare its labels, units and dates with that example before preparing a wider review. If a value is uncertain, record the uncertainty in your working notes and resolve it with the person who holds the source information. A neatly presented result is useful only when the assumptions behind it are also clear.
Keep a copy and agree the next action
Use Download report to keep the written result and Download results CSV when you want to work with its records in a spreadsheet. Save inputs keeps a JSON file that can be restored into this same tool later. Editing an input hides the old result until you run the tool again, which helps avoid sharing an output that belongs to an earlier set of assumptions.
Where report emailing has been configured, Email my results lets you request a copy and send the same inputs and result to this site for follow-up about your request. The form explains who receives the copy and requires a completed security check. Check the recipient address carefully before sending. The email request uses the current result, so review the entered information before choosing that option.
Questions to settle before sharing
Decide who should check the source information, who can approve the proposed next step and when the record should be reviewed again. Keep the output with its underlying documents so a later reviewer can distinguish the facts entered today from any changes made afterwards. If the result prompts a query, describe the specific input or assumption you want checked instead of sending an unexplained total on its own.
