CSRD & CSDDD: What the EU trilogue changes mean — and what to do now

The rules changed. The bar did not. Here's what the latest CSRD and CSDDD updates really mean for sustainability leaders.

The EU officially agreed on a major recalibration of the Corporate Sustainability Reporting Directive (CSRD) and the Corporate Sustainability Due Diligence Directive (CSDDD) on December 16, 2025.

The goal is simplification but not elimination. While fewer companies will be in scope in the near term, expectations for data quality, governance, and value-chain visibility remain firmly intact.

Here’s what matters most.

EU Trilogue updates, at a glance

The revised EU Omnibus Package significantly narrows scope, delays timelines, and introduces more proportional, risk-based requirements, especially for value-chain due diligence. 

At the same time, it preserves the core architecture of CSRD and CSDDD: ESRS-aligned reporting, double materiality, and investor-grade disclosures.

CSRD & CSDDD changes at a glance
Area Before (Pre-Omnibus) Now (Agreed Outcome) What to do now
CSRD – EU company scope 250+ employees and €50M turnover (or €25M assets) 1,000+ employees and €450M net turnover Reassess in-scope status. If exempt short-term, maintain CSRD-grade data for investors and customers.
CSRD – Non-EU companies Scope unclear; broad intent to include large non-EU groups In scope if €450M EU turnover and an EU branch/subsidiary with €200M turnover Model EU revenue exposure and confirm the reporting entity early to avoid last-minute restructuring.
CSRD – Reporting timelines Wave 2 reporting starting FY 2025 First reports in 2028 (FY 2027); exemptions likely for FY 2025–2026 Use the delay to fix data foundations, automate collection, and prepare for assurance.
CSRD – ESRS requirements Full ESRS set with high datapoint volume Simplified ESRS coming (fewer datapoints, clearer materiality) Don’t pause materiality work—design processes that can flex as ESRS evolves.
CSRD – Double materiality Required Unchanged Treat materiality as an operating model, not a one-time assessment.
CSRD – Value-chain data requests No explicit cap on supplier data Caps for suppliers with <1,000 employees (VSME standard) Shift from blanket questionnaires to targeted, risk-based supplier engagement.
CSDDD – Scope thresholds 1,000+ employees and €450M turnover 5,000+ employees and €1.5B turnover If you drop out of scope, expect indirect pressure from customers who remain in.
CSDDD – Due diligence approach Perceived Tier-1–first focus Fully risk-based across the value chain Prioritize severity and likelihood of impacts—not supplier tier.
CSDDD – Climate transition plans Mandatory Removed from CSDDD (still disclosed under CSRD, if applicable) Continue transition planning if reporting under CSRD or responding to investor scrutiny.
CSDDD – Timeline Compliance from July 2027 Compliance from July 2029 Build due-diligence workflows now while expectations are clearer and timelines are flexible.
CSDDD – Penalties & liability Penalties up to 5%; civil liability included Penalties capped at 3%; civil liability removed Focus less on fear-driven compliance and more on defensible, auditable processes.

CSRD: Key changes 

Who’s in scope now for CSRD post-trilogue discussions

 CSRD now applies to large companies only:

  • 1,000+ employees
  • €450M+ net turnover

This reduces the number of mandatory reporters by an estimated 80%.

Non-EU companies are in scope if they:

  • Generate €450M+ EU turnover, and
  • Have an EU subsidiary or branch generating €200M+ turnover

Timing adjustments

  • Wave 2 companies: first CSRD report in 2028 (FY 2027)
  • Non-EU companies: first CSRD report in 2029 (FY 2028)

Many companies may be exempt for FY 2025–2026, depending on Member State implementation.

What doesn’t change

  • Double materiality stays
  • Reporting must still align with ESRS
  • Limited assurance remains the standard (for now)

A simplified ESRS, expected in 2026, will require fewer datapoints and clearer materiality guidance.

CSDDD: A shift to risk-based due diligence

CSDDD has been streamlined even further, with a clear move toward proportionality.

Key updates to CSDDD post-trilogue discussions

  • Scope raised to:
    • 5,000+ employees and €1.5B global turnover (EU companies), or
    • €1.5B EU turnover (non-EU companies).
  • Implementation delayed:
    • National transposition by July 2028.
    • Company compliance required by July 2029 .

What’s new (and notable) for CSDDD

CSDDD is taking a fully risk-based approach to due diligence. Companies can prioritize the most severe and likely risks across the value chain, not just Tier 1 suppliers. This includes:

  • SME protections: data requests must be genuinely necessary and proportionate
  • Climate transition plans removed from CSDDD (but still disclosed under CSRD, where applicable)

Penalties capped at 3% of global turnover, and civil liability has been removed from CSDDD mandates.

What this means for Sustainability leaders

Even if your company is no longer immediately in scope, three realities remain:

Investors still expect CSRD-grade data

CSRD has become the de facto benchmark for decision-useful sustainability disclosures.

Value-chain pressure hasn’t disappeared

Large companies will still need high-quality supplier data — just collected more strategically.

The window to modernize is open

The delay creates time to fix fragmented systems, automate data collection, and operationalize materiality—before reporting becomes mandatory again.

What to do next for future CSRD and CSDDD preparedness

If CSRD or CSDDD is on your radar —even if timelines moved — now is the moment to:

✅ Reassess in-scope status under the new thresholds

✅ Refresh or run a double materiality assessment aligned to revised ESRS

✅ Map value-chain data gaps with a risk-based lens

✅ Centralize sustainability, climate, and ESG data in one system

✅ Prepare for audit-ready, limited-assurance reporting
