CSRD, ESRS and EU taxonomy data systems

Sustainability reporting under the CSRD and the European Sustainability Reporting Standards is a data engineering problem before it is a disclosure problem. The Omnibus simplification agreed in December 2025 narrowed which undertakings must report, but those still in scope face the same requirement for evidence that will stand up to assurance. EU taxonomy alignment adds activity-level data on revenue, capital expenditure and operating expenditure.

We build the data pipelines between ERP systems such as SAP S/4HANA, energy and emissions sources and the reporting tool. We document lineage, define controls and keep the logic maintainable, so that next year's report does not start again from spreadsheets.

Typical deliverables

• ESRS datapoint mapping to source systems and owners
• EU taxonomy eligibility and alignment data model at activity level
• Data lineage and control documentation prepared for limited assurance
• Reporting platform selection and integration plan
