EU Omnibus Package: Key Takeaways & Impacts on CSRD

This action is significant and wide-ranging, affecting technical scoping and data points, reporting obligations, and compliance timelines. Here’s an overview of what you need to know from Principal Consultant Leah (Foertsch) O'Neill and Sustainability Advisory Senior Consultant Savannah Rodrigue from Arcadis.
Key Impacts on CSRD:
- Scope: Only very large companies (>1,000 employees AND >€50M turnover or >€25M assets) would be subject to reporting requirements, cutting out 80% of companies originally in scope.
- Threshold: Non-EU parent companies would need ≥€450M EU turnover to fall in scope, and the EU branch threshold aligns to €50M, matching the “large” company size. This is only about 900 companies globally.
- Start dates: Companies originally due to start reporting in 2026 (FY 2025) and 2027 (FY 2028) would receive a 2-year delay.
- Reporting standards: Sector-specific requirements would be removed and the planned upgrade to reasonable assurance would be cancelled (limited assurance would stay).
- Data points: The number of mandatory ESRS data points would be substantially reduced.
Next Steps Companies Should Consider Taking:
- Companies affected by these changes should assess their reporting obligations, compliance timelines, and due diligence responsibilities to prepare for the new regulatory landscape. Companies should continue to prepare for the EU’s
corporate sustainability reporting requirements to strengthen their business resilience and create value.
- For CSRD, we recommend that large EU (wave 2) & non-EU (wave 4) companies stay the course and focus on preparing to report. If anything, potential delays in timelines should provide companies with more time to prepare and enhance
their data management and reporting readiness instead of rushing the process.
- For companies that are currently in an unclear position, such as small and medium enterprises (SMEs), it would likely be difficult to stop the process and start again; keep in mind that a restart is coming unless you fall out of the
thresholds. It is important to confer internally with your legal, finance, and executive leadership to determine your risk appetite for continuing preparation for reporting versus waiting for timeline updates.
- If your company were to fall out of the required threshold, we recommend that you consider continuing to focus on the CSRD components that provide strategic value to your business, such as conducting double materiality assessment to assess your business strategic priorities and embedding sustainability in your business strategy and functions.
