ESG excellence
within reach.
Your sustainability labelling. Simplified.
We automate every step and guide you end to end, turning your ESG compliance from months into days, across 70+ frameworks.
One platform for all your ESG frameworks
ESG compliance, finally on your timescale
Where reporting used to take months of spreadsheets and back-and-forth, Heolenn automates, guides and de-risks every step.
Your customers, your lenders and your tenders are already asking
ESG compliance is no longer an internal project you start when time allows. It reaches you through your buyers, your banks and your tender documents, on deadlines you do not set.
Anticipate instead of scrambling
Requirements and deadlines across your frameworks are tracked in one place. You stop discovering an obligation on the day it applies.
Answer once, not ten times
A customer ESG questionnaire is filled in once, then reused for the next one and for your other frameworks. That is where the 60 % reporting time saving comes from.
Clear the ESG criterion in tenders
It weighs more every year in public and private procurement. When the tender lands, your evidence is already filed.
Keep control of your data
European hosting, European jurisdiction, GDPR compliance. Language model processing takes place in the United States, under standard contractual clauses, with no training on your data. French residency available on a dedicated instance.

The questions we hear most
How is Heolenn different from carbon tools?
Most tools on the market are carbon-only and convert euros into CO₂ via opaque monetary factors. Heolenn covers the whole of ESG (CSRD, EcoVadis, B Corp, CDP, GRI…) and relies on your real activity data with verified physical factors, auditable and compliant.
How long does it take to produce a report?
What used to take months now takes days. Scoping is instant, data collection is guided, and the AI speeds up drafting. Timelines depend on your data maturity, but the goal is constant: from months to days.
How many frameworks are covered?
Over 70 ESG frameworks, including CSRD/ESRS, EcoVadis, B Corp, CDP, GRI, SASB, VSME, ISSB, GHG inventories and the EU Taxonomy. An answer entered once is automatically reused across every applicable framework.
Is my data secure?
Yes. Hosted on European servers, GDPR-compliant, and a strict no-Big-Tech, no-ad-cookies policy. You keep full control and traceability of your data.
Can the AI make things up?
No. Heolenn AI never generates data: it structures and drafts from your entries, always sourced. Every answer goes through human validation before publication.
