ESG and CSRD reporting in Luxembourg, sustainability, ESRS and taxonomy.
FSL prepares your sustainability reporting: data collection, CSRD statements under ESRS standards and taxonomy alignment. We structure the data and produce the report; assurance (audit) and legal opinions sit with dedicated parties. FSL handles reporting and operational compliance; regulated legal advice and authorisations (CSSF) are coordinated with our partner lawyers.
CSRD reporting is the obligation to publish sustainability information under the European ESRS standards. Directive (EU) 2022/2464 (CSRD) sets the framework; the 2026 Omnibus package raised the thresholds and postponed the timelines.
Directive (EU) 2022/2464 (CSRD) and ESRS standards; 'stop-the-clock' Directive (EU) 2025/794; Omnibus I published in the OJEU on 26 February 2026 (in force 18 March 2026), scope raised to companies with over 1,000 employees and over €450M net turnover; simplified ESRS expected mid-2026 (FY2027 application).
Key takeaway
- Since the 2026 Omnibus, scope is concentrated on the largest companies (>1,000 employees and >€450M turnover).
- Timelines were postponed (wave 2: FY2027; wave 3: FY2028).
- FSL prepares the report; assurance remains with an approved auditor.
