; ESG standards: understand, compare, unify with Harnest;
Transparency, compliance, comparability... ESG requirements are multiplying, driven by a diversity of frameworks with sometimes very different logics.
Each standard meets a specific objective — voluntary communication, regulatory obligation, investor expectations — but all have one thing in common: they are based on reliable, structured and interoperable ESG data.
With Harnest, you no longer have to choose between compliance and efficiency.
Our platform structures your ESG data at the source, identifies the matches between indicators, and dynamically activates the modules required for each repository. You produce several reports from a single database, you limit re-entries, and benefit from a global vision of your ESG issues and indicators.

Why so many ESG standards?
(VSME) aim to involve small structures in the dynamic of sustainability without overburdening them.
(France Invest, EDCI) seek to harmonize the data transmitted in B2B relationships (funds → participations, customers → suppliers).
(CSRD, Taxonomy, SFDR) require mandatory, structured and auditable reporting.
like the GRI, are historically designed for transparency towards stakeholders.
What Harnest allows: a unique, multi-referential ESG database
Harnest is based on a structured ESG table, compliant with European standards (ESRS) and enriched with specific modules per repository.
Thanks to this architecture:
- Once you collect your ESG data, it is intelligently reused in all your reports
- You avoid duplicates, inconsistencies or conflicts of indicators
- You can produce several different reports (CSRD, VSME, France Invest...) from the same database
Unifying does not mean oversimplifying
Harnest doesn't just “translate” from one repository to another:
- It structures the data at the source, according to an enriched pivotal model (inspired by ESRS),
- It automatically identifies the correspondence between indicators (e.g. a CO₂ KPI useful to the CSRD, the GRI and the EDCI),
- It dynamically activates the necessary modules according to the standards targeted by the organization.
Use case: the same reporting feeds several deliverables
Concrete example: An ETI in the portfolio of an infrastructure fund produced with Harnest:
- its VSME report (external communication)
- a France Invest + EDCI sheet (sent to its investor)
- preparation for the CSRD (in 2026)
👉 all produced from the same Harnest database, with personalized deliverables, without duplication.
