Audit-ready water reporting for ESRS E3
Turn unverifiable supplier declarations into satellite-measured water data — structured, defensible and ready to consolidate in your sustainability report.
ESRS E3, Omnibus 2026, GRI 303, CDP Water: the new water-data standard
The European ESRS E3 - Water standard, simplified by Omnibus I 2026, structures how large companies must publish their water impact (consumption, withdrawals, discharges, water-stress exposure). The timeline is nuanced — thresholds raised to around 1,000 employees and €450M revenue, progressive application around 2027-2028 — but the direction is clear: water data must become verifiable.
Add GRI 303 requirements, the CDP Water questionnaire — increasingly scrutinised by investors — and growing B2B buyer expectations. On the agricultural scope 3, which usually carries most of the footprint, an unverifiable supplier declaration is no longer enough.
The real risk lies in report assurance. Statutory auditors are tightening their criteria: a water indicator without an audit trail to the source is increasingly hard to defend. Anticipating today — by building measured, historised data — secures the trajectory of the next reporting seasons.
From declarative to auditable
Why a classic supplier report no longer secures your assurance.
Today
- Unverifiable supplier declarations
- Risk on report assurance by the statutory auditor
- Insufficient granularity on agricultural scope 3
- Indicators not comparable year over year

From satellite to report
Three steps to compliance
Independent per-field measurement
Sentinel-2 imagery and agronomic AI: water data is measured at the source, without depending on supplier declarations.
Structured by ESRS E3 indicator
Volumes, intensities, water-stress exposure: each indicator is computed and aligned with ESRS E3 - Water, GRI 303 and CDP Water.
Export to your ESG stack
Plug Seabex into SAP Sustainability, EcoVadis, CDP Water or your GRI 303 tools via structured export or documented API.
Standards covered
One field measurement — multiple standards fed. Structured export and documented API to plug into your ESG stack without double entry.
Mini glossary
Key terms of water reporting
European sustainability reporting standard dedicated to water, simplified by Omnibus I 2026. Structures disclosures on consumption, withdrawals, discharges and water-stress exposure.
Corporate Sustainability Reporting Directive: the EU framework requiring large companies to publish a sustainability report aligned with ESRS. Thresholds raised and timeline pushed back by Omnibus 2026.
Water mobilised upstream and downstream of your activity — for agri-food, the agricultural upstream concentrates most of the water footprint.
International GRI standard dedicated to water and effluents: withdrawal, consumption, discharges and water-stressed areas.
Annual CDP questionnaire focused on water performance, increasingly scrutinised by investors and B2B buyers.
