Already using Persefoni? What its record leaves open
Limitations the Persefoni profile records:
- Some product pages retain coming-soon labels that need reconciliation
- Free access does not establish every required export entitlement
- The reviewed pages do not establish an Advanced subscription amount
Available only under stated conditions or not documented (checked 3 October 2026): Supplier data exchange; API and Integration Hub ingestion; Calculation traceability; Review controls and activity history; Plan-specific reporting exports; AI-assisted anomaly detection; Net-zero scenario modelling and target tracking. Check each against the contract you hold.
Listed candidates that document a capability with a related name (confirm the scope in a demo):
- “Net-zero scenario modelling and target tracking”: Normative's “Reduction targets and scenario analysis” and Sweep's “Reduction targets and financial scenarios”.
Persefoni evaluation checks, for every candidate
- Source data and boundaries: Bring records with mixed units and an intentional duplicate. Ask the vendor to identify the entity, period and activity for each record and demonstrate rejected or corrected inputs. Source
- Factor selection and reproducibility: Pick one material result. Request its input, formula, unit conversion, factor source and dataset version. Establish who approves substitutions and how historic results are reproduced. Source
- Changes and review controls: Demonstrate a correction after review. Check prior values, permissions and the effect on a closed period. Resolve inconsistent release labels in the public documentation before accepting the workflow. Source
- Reporting deliverables: Ask for a sample output from the exact plan. Distinguish a narrative report, quantitative metrics and the calculation evidence an external reviewer will request. Source
- Integration and ongoing ownership: Map an actual source system to the proposed connector. Agree credentials, field mapping, failed-import handling, reconciliation and the people responsible after onboarding. Source
Leaving Persefoni: what to plan for
- Carry the reasoning, not only the totals. The product shows formula, conversion and factor detail for a calculation, so prior-year results can be reproduced here. A replacement that applies different factors will show a year-on-year change caused by method and not emissions. Export each past inventory with its factor source and dataset version, and decide who approves any substitution when history is restated.
- Suppliers who responded to data requests will have to be asked again, and the record separates responding from sending by plan. Before leaving, export what each supplier provided, keeping estimated values distinguishable from supplier-provided ones, with the retained source file. A new tool can import the numbers, but only the old record shows which were estimates and who supplied the rest.
- A locked report cannot be rebuilt in another tool in its locked state. Attachments, activity tracking and locking are what the report builder offers, so take copies of every issued disclosure with its attachments and activity trail while access lasts. A reviewer may ask next year why a number changed, and the effect on a previously issued report is exactly the evidence they would want.
Who may have reason to stay with Persefoni
- Cost is the plainest reason to stay. The entry plan is described as permanent and free, not a trial, and a single user producing a recurring inventory pays nothing for it. The caveat is that extra users, selected exports and support can require upgrades, so confirm that the outputs your customers request are inside the free scope before comparing any paid alternative.
- Target tracking is easy to underestimate. The scenario tool generates reduction scenarios and follows progress against targets, and it is described as an add-on, so teams already paying for it hold scenario assumptions that a move would have to recreate. Decide whether those assumptions are documented outside the platform, because without that the comparison between tools starts from nothing.
- A move motivated by operational needs will not be solved by another carbon tool. The record says this product is less suitable as a replacement for incident or permit management, and that its waste and water tracking is activity tracking rather than proof of permit compliance. If the gap is operational, look at a different category and keep the inventory where it is.
What to test in a trial of a replacement for Persefoni
- Feed every candidate the same file of utility and activity records, with units mixed on purpose and one duplicate planted. Check what is rejected, what is converted silently, and whether each row is tied to an entity, a period and an activity. The comparison is how visibly the tool handles bad input, since a clean sample file proves very little.
- Correct a record after review, in a period already closed, and look for the previous value, the editor, the reason and the effect on what was issued. Public pages for this product carry some release labels that disagree, so insist on seeing the control in your own demonstration account instead of accepting a description from the website or a slide.
- If anomaly flags matter to you, seed the trial data with two real errors and one legitimate seasonal spike. Count what each candidate flags and what it misses, and see who decides the disposition of a flag. The record treats flags as prompts for a reviewer, and neither validation nor assurance, so thresholds and false alarms are the figures to compare.
