Frequently asked questions
Including the ones whose answer does not favour us.
Same principle as the rest of the site: we claim only what we can prove, and we say what we cannot do.

In short
Who publishes the products, how figures are calculated, which regulatory deadlines are coming, and what happens to data. Every answer on this page reads on its own, with its date, including the ones that do not favour us.

STRATA ESG is a French software publisher building the system where the sustainability data of European small, medium and mid cap companies lives. The principle fits in one sentence: data is entered once, with the document that founds it and the method that computes it, then returned in the grammar of every expected framework.
STRATA ESG is the brand and the parent company. ESG Optimizer is the product, the cockpit where the data lives and where the subscription happens. The parent company site orients and explains, it does not sell and hosts no account: each product carries its own pricing page and its own checkout.
Five building blocks, each on its own domain. ESG Optimizer, the cockpit, is available. STRATA Scope, the carbon module, is available. STRATA Watch, regulatory monitoring, is available. STRATA Foundation, the free starting point and the sector comparison baseline, is available. STRATA Academy, contextual training, is online, with its catalogue being built. The offer is also served in West Africa, on its own domain and price list.
That what is sold is not a score but the ability to defend every figure in front of an auditor, a bank, a client or a court. Concretely: a versioned vault, a graph linking every value to its document both ways, a hash chained registry, and a reproducible calculation. A report generator cannot claim that category without lying, because it lacks the objects.

No. The exact wording, held everywhere: extraction and drafting are assisted, the calculation never is. No value produced by a generative process enters a score, an index or a projection. That is why the same analysis, rerun on the same data, returns exactly the same result, today and in two years.
It is flagged as missing and it pulls the index down. It is never quietly estimated, never replaced by a sector average, never filled with a default. An incomplete file has to show, otherwise it becomes indefensible the moment someone checks it.
No, and that limit is written on every deliverable. Our scores are indicative and do not replace an audit by a registered statutory auditor. What they provide is the file that audit can rely on: documents in their place, assurance levels field by field, and the state of the file at the closing date rather than today's.
No. We are neither an authorised rating provider nor a certification body, and we claim to be neither. We prepare a file and make it verifiable; validation belongs to an authorised third party.
Yes, in full, with its version and its date. Nothing requires us to: the European regulation on ESG rating providers, applicable since 2 July 2026, requires regulated actors to publish their methods, and we are not one. We publish ours voluntarily, so that an advisory firm, a statutory auditor or a bank can audit it without asking permission.

It is the sustainability reporting standard for unlisted companies, adopted by delegated regulation of the European Commission on 3 July 2026, alongside the revision of the ESRS standards. It targets companies up to one thousand employees and four hundred and fifty million euros of turnover, that is to say precisely those the Omnibus reform took out of the scope of the sustainability reporting directive.
Not everything. The value chain cap, set by the Omnibus directive, prevents a client from requiring a partner with fewer than one thousand employees to provide more than the content of the voluntary standard, adopted by delegated regulation on 3 July 2026. A two hundred line in house questionnaire is not enforceable as such; the cap has a legal basis. It takes effect for financial years starting from 2027. Until then, it is invoked in a commercial negotiation as an adopted standard and a known ceiling, not as a prohibition already enforceable before a court.
It probably takes you out of the legal obligation, not out of the commercial demand. The directive published in the Official Journal of the European Union on 26 February 2026 narrows the scope of the sustainability reporting directive from around fifty thousand to around five thousand companies. But the remaining five thousand are the most international ones, and they keep asking their suppliers for data. The pressure does not disappear, it standardises.
Four are already published. The directive on environmental claims on 27 September 2026, with up to four per cent of national turnover at stake. The imported deforestation regulation on 30 December 2026 for large and medium companies, then 30 June 2027 for micro and small companies. The greenhouse gas emissions report, already in force, with a fine of up to fifty thousand euros, one hundred thousand on repeat. And since June 2024, access to some public transition funding conditional on an up to date emissions report.

Nothing beyond what it was uploaded for. No reuse, no resale, no model training on client documents. The parent company site itself collects nothing: it hosts no account, drops no tracker before your explicit choice, and the only data it processes is the email address of whoever writes to us.
With Vercel Inc., a company incorporated in the United States and established in California. We write it plainly rather than displaying a European hosting claim that nothing would establish. Transfers outside the European Union rely on the standard contractual clauses adopted by the Commission in 2021. The detail is in the privacy policy and in the legal notice.
Adama Diallo, sole trader, registered with the French national business register, operating the STRATA ESG brand. The full identity, the registration number, the address and the value added tax regime appear in the legal notice, with no placeholder left to fill.
Because we ask our clients to claim only what they can prove, and a rule that does not apply to whoever states it is not a rule. Five commercial promises were removed from our pages because the code did not hold them. The list is public, dated, and it will grow.
Write to us. If the answer can serve others, it will join this page, with its date.
