You already have a sustainability report. We make it filable.
We tag sustainability statements against the ESRS XBRL taxonomy, ISSB-aligned iXBRL, and other regional digital reporting formats — at a published per-page price, with no software licence and no lock-in.
One team, every major ESG reporting framework
Sustainability reporting mandates are converging around structured, machine-readable data — but which format, which taxonomy, and which deadline depends entirely on where you report. We track all of it so you don't have to.
ESRS XBRL (CSRD)
The EU's sustainability reporting taxonomy — what it covers, and where the digital tagging mandate actually stands.

Most XBRL tagging providers built their expertise on financial statements. ESG data is a different animal — narrative-heavy disclosures, interoperability requirements between frameworks, and a regulatory landscape that's still actively being written.
Framework interoperability
ESRS and ISSB standards are designed to interoperate but aren't identical — getting the mapping right between them takes specialist judgment.
A moving regulatory target
Thresholds, timelines, and even the tagging mandate itself have shifted multiple times since 2023. We track every change.
Data that isn't always numeric
Narrative disclosures, qualitative risk assessments, and scenario analysis all need tagging — not just balance sheet figures.

Frequently Asked Questions
Is ESRS XBRL tagging mandatory right now?
Not yet, as of mid-2026. The European Commission and ESMA are still finalising the Regulatory Technical Standard that would make digital tagging of ESRS sustainability statements mandatory — EFRAG handed over its proposed taxonomy in August 2024, but the formal mandate hasn't been confirmed. See our CSRD Omnibus guide for the current status.
Does the CSRD still apply to my company?
The scope was narrowed considerably by the EU's Omnibus reforms — the current threshold is broadly 1,000+ employees and €450 million+ turnover, with listed SMEs excluded entirely. See our who must report guide for the detail.
Do you only work with EU companies?
No — we work with companies reporting under ESRS/CSRD, ISSB-aligned frameworks (IFRS S1 & S2), and other regional sustainability disclosure regimes. See our global standards tracker.
