Persefoni: a free footprint, paid report add-ons, and financed emissions
Persefoni describes its carbon accounting software as a platform to “measure, report, decarbonize”, with a free Pro plan for simpler companies and a financed-emissions product for banks, investors and their portfolio companies.
This profile uses only Persefoni’s own pages, read on 1 October 2026, and one fact from Forrester’s own page, and sets each claim beside the UK rule it touches.
Nobody here has tested the product, so there is no rating; the checklists below turn the claims into things to see on your own data.
What it says it is
Persefoni, as Persefoni describes it
Persefoni sells two plans and a set of report add-ons.
Persefoni Pro is pitched at companies with low to medium complexity that need a Scope 1, 2 and 3 total to answer customers and investors.
Persefoni Advanced is pitched at enterprise-scale programmes, with market-based Scope 2 for renewable energy tracking, finer emission-factor granularity, reduction modelling and APIs.
The reporting layer is split: a Sustainability Report Builder, which its pricing page says is free in Pro, and a list of GHG Metrics Reports, which it calls paid add-ons.
That list names CDP, SECR, CA-CCDAA, ISSB and CSRD reports, plus a GHG methodology report.
Its homepage also describes AI features, one of which — mapping spend files to emission factors in natural language — it labels as coming soon.
The claim “assurance-grade” is Persefoni’s; in the UK no law requires a company’s sustainability figures to be assured, so the useful question is what an assurer would see, not whether the tool carries the label.

| “Assurance-grade GHG emissions reporting for every major climate disclosure regulation” | Homepage |
| Pro: “Best for companies with low to medium complexity of operations” | Pricing |
| Advanced: “Best for sustainability-ambitious or enterprise-scale companies” | Pricing |
| “PCAF-aligned financed emissions calculations that support any data quality score” | Financed emissions |
| Persefoni Copilot, anomaly detection, and emission-factor mapping it marks “Coming Soon” | Homepage |
Financed emissions
PCAF-aligned, it says — so ask which PCAF
Financed emissions are the emissions of the companies and assets a lender or investor finances, accounted for under Category 15 of the GHG Protocol Scope 3 Standard.
The method most institutions use is set by the Partnership for Carbon Accounting Financials, and Persefoni’s financed emissions page says its calculations are “PCAF-aligned” and “support any data quality score”.
PCAF’s financed-emissions Part A is now in its third edition, published December 2025, and covers ten asset classes rather than the original six.
PCAF itself says its “Built on GHG Protocol” mark covers only the six first-edition asset classes, because the GHG Protocol closed that review service before the later additions — sovereign debt among them — were reviewed.
So the demo question is which edition, and which asset classes, the calculations follow.
Persefoni’s investor reporting page describes aggregating metrics such as weighted average carbon intensity by portfolio, fund and asset class, and a Scope 3 Data Exchange for requesting footprints from portfolio companies.
Where UK SRS S2 is applied, paragraph B59A of the UK standard adds a duty IFRS S2 does not carry: an entity that finds it impracticable to estimate financed emissions reliably for the same period as its accounts must explain why.
The screener beside this sorts the fifteen Scope 3 categories against UK SRS S2, including the financed-emissions limb for asset management, commercial banking and insurance; the fuller position is on UK SRS Scope 3 reporting.
Scope 3 · the fifteen categories · relevance screen
For each category, do you have the activity at all?

Anything you buy that is not capital goods.
2 · Capital goods (upstream)
Plant, equipment, buildings and vehicles bought in the year.
3 · Fuel- and energy-related activities (upstream)
Upstream emissions of the fuel and power you use, and grid losses.
4 · Upstream transportation and distribution (upstream)
Freight and storage you pay for, inbound and between your sites.
5 · Waste generated in operations (upstream)
Disposal and treatment of your waste by third parties.
6 · Business travel (upstream)
Flights, rail, hotels and hire cars for staff.
7 · Employee commuting (upstream)
Staff travel to work, and homeworking where you count it.

Persefoni, regime by regime
What its pages name, and what each UK rule asks
| Regime | What Persefoni’s pages say | What the rule asks | Ask to see |
|---|---|---|---|
| SECR (UK) | “SECR GHG Metrics Report”, a paid add-on | Schedule 7 lines in the directors’ report: kWh, emissions, ratio, method, comparatives (¶20D) | The add-on’s output on a UK company’s data |
| UK SRS / IFRS S2 | “ISSB GHG Metrics Report”; UK SRS not named on the pages read | Comply or explain for UKLR 6, 14, 15, 16 and 22 from 2027 (PS26/19) | Location-based Scope 2 and the investee split |

| ESOS | Not named on the pages read | An energy audit and notification, Phase 4 by 5 December 2027 | Total energy in kWh by purpose |
Several of the searches that reach this page ask how Persefoni does on one regime at a time, so the table answers them in that shape.
The column on the left is only what Persefoni publishes; the third column is the rule, from its owner.
Persefoni and SECR compliance in the UK
A SECR report add-on — against Schedule 7
SECR is not a carbon report a company files on its own; it is a section of the directors’ report, required by Schedule 7 to SI 2008/410, and the duty sits with the company and its directors.
For a large unquoted company, paragraph 20B sets qualifying conditions of “not more than” £36 million turnover, £18 million balance sheet and 250 employees, so a company is in scope when it exceeds at least two of them.
Paragraph 20D then asks for UK energy use in kWh, emissions from gas, purchased electricity and transport fuel, at least one intensity ratio, the methodology, the principal energy-efficiency measures and last year’s figures.
A company that used 40,000 kWh or less states that the figures are not disclosed for that reason, so a tool should produce that statement rather than an empty table.
The government’s SECR guidance assumes the UK government conversion factors for the activity year; a global factor library should say which set converted each UK figure.
A UK company subject to SECR will therefore want to see the add-on’s output on its own data, line by line, before treating it as the directors’ report section.
The lines in full are on the SECR reporting guide, and the scope tests on SECR requirements.
UK SRS and the FCA’s final rules
An ISSB report — and what UK SRS adds
UK SRS S1 and S2 were published by the Department for Business and Trade on 25 February 2026 as voluntary standards based on IFRS S1 and S2.
On 30 September 2026 the FCA published PS26/19: listed companies in UKLR 6, 14, 15, 16 and 22 report against UK SRS on a comply-or-explain basis for accounting periods beginning on or after 1 January 2027, with first reports in 2028.
The final rules changed the proposal in CP26/5, which would have made UK SRS S2 mandatory.
Under PS26/19 nothing in UK SRS is mandatory for a listed company, though each gap has to be explained; the consultation remains the record of what was proposed.
A listed company may take one year’s relief from disclosing Scope 3 under UK SRS S2, and says that it is doing so.
Persefoni lists an ISSB GHG Metrics Report; UK SRS S2 measures to the GHG Protocol Corporate Standard and asks for location-based Scope 2 and a split of Scope 1 and 2 between the consolidated group and other investees, so those are the outputs to check.
What UK SRS asks in full is on UK SRS S1 and S2, and the explanation mechanics on UK SRS compliance.
For banks and asset managers, the FCA’s separate ESG sourcebook regime still applies to in-scope firms; it is covered on FCA sustainability disclosure requirements.
What third parties say
One analyst placing, with its date
The Forrester Wave: Sustainability Management Software, Q2 2024 evaluated 13 providers on 24 criteria and names Persefoni a Leader.
The quarter matters: it is a mid-2024 view of global sustainability management software, and it does not score SECR, ESOS or UK SRS output.
Persefoni’s homepage also lists advisory and technology partners; those are its own statements, so this profile does not repeat them.
Voluntary reporting through CDP is something Persefoni’s Pro plan names directly, and CDP is the third party to ask about its own questionnaire.

Tick the regimes that apply to you and the checklist builds the outputs each one requires, cited to the provision.
Below the list it shows what Persefoni’s own pages say for each ticked regime, or that no claim was found on the pages read.
The same checklist runs on every vendor profile, so Climatise and Normative can be read against the same list.

Pricing
Free to start, Enterprise level · TBD beyond it
Persefoni’s pricing page says the Pro plan is free to start and needs no credit card.
It publishes no figure for Persefoni Advanced or for the GHG Metrics Report add-ons, including the SECR report, and this site does not estimate one.
For a UK company the realistic cost question is therefore Pro plus whichever add-ons its regimes need, or Advanced, each quoted in writing.
Every vendor’s published price, or its absence, is listed on carbon reporting software.

Frequently asked
Persefoni, answered from its own pages
How does Persefoni handle SECR compliance in the UK?
Persefoni’s pricing page lists a “SECR GHG Metrics Report” among its GHG Metrics Reports, which it describes as paid add-ons, including to the free Pro plan.
SECR itself is a directors’ report duty under Schedule 7 to SI 2008/410: energy in kWh, emissions from gas, purchased electricity and transport fuel, at least one intensity ratio, the methodology, the energy-efficiency narrative, last year’s figures, and a statement where consumption was 40,000 kWh or less.
Ask to see the add-on’s output against each line.
Is Persefoni free?
Persefoni publishes a Pro plan it describes as “Start for free” with “No Credit Card Required”, for companies with low to medium complexity responding to customer and investor requests.
Its GHG Metrics Reports are paid add-ons and Persefoni Advanced carries no published figure, so this site records the paid tiers as Enterprise level · TBD.
Is Persefoni an IFRS S2 climate disclosure platform?
Persefoni lists an “ISSB GHG Metrics Report” and a Sustainability Report Builder.
IFRS S2 asks for more than emissions — governance, strategy, risk management and other metrics — and its UK version, UK SRS S2, is used on a comply-or-explain basis by listed companies in UKLR 6, 14, 15, 16 and 22 for periods from 1 January 2027.
Ask which disclosures the builder covers beyond the GHG metrics.
Does Persefoni calculate financed emissions?
Persefoni says it delivers “PCAF-aligned financed emissions calculations that support any data quality score”, with portfolio analytics such as emissions intensities.
PCAF’s financed-emissions Part A is now in its third edition, published December 2025, with ten asset classes, so ask which edition the calculations follow.
Does Persefoni cover CBAM?
CBAM was not named on the Persefoni pages read for this profile.
The UK CBAM applies from 1 January 2027 to specified goods in five sectors — aluminium, cement, fertiliser, hydrogen, and iron and steel — under Part 5 of the Finance Act 2026, and it is a separate regime from the EU CBAM.
It is a charge on importers of those goods rather than a corporate footprint, so ask any vendor which CBAM it means.
Is Persefoni a Forrester Wave Leader?
Forrester’s own report page for The Forrester Wave: Sustainability Management Software, Q2 2024, which evaluated 13 providers on 24 criteria, is the place to check it; the report names Persefoni a Leader.
It is a Q2 2024 evaluation of global sustainability management software and scores no UK regime.
Does Persefoni support CDP?
Persefoni lists a “CDP GHG Metrics Report” and says its Pro plan supports responses to customer supply-chain requests such as CDP and EcoVadis.
CDP is a voluntary disclosure system, and a CDP score has no regulatory status in the UK.
Who is Persefoni built for?
By its own description, both: the Pro plan is for companies with low to medium complexity answering customer and investor requests, and Persefoni Advanced is for enterprise-scale programmes.
Its financial-services pages address asset managers, lenders and their portfolio companies.
