The European Commission has released its new Omnibus Simplification Package, introducing significant modifications to the ESG compliance framework affecting thousands of companies across Europe. The package addresses ongoing concerns about regulatory complexity while maintaining environmental policy objectives.
Understanding CSRD vs. CSDDD: Key Differences
Before examining the changes, it’s essential to understand the distinction between these two major directives:
Aspect | CSRD | CSDDD |
---|---|---|
Legal Nature | Reporting obligation | Behavioral obligation |
Implementation Timeline | Phased approach: • 2025: Listed companies 500+ employees • 2026: Other large companies • 2027: Listed SMEs • 2029: Non-EU companies (meeting EU revenue criteria) | Phased approach: • 2027: 5,000+ employees + €1.5B revenue • 2028: 3,000+ employees + €900M revenue • 2029: Other applicable companies |
Core Focus | • ESG disclosure requirements • Climate transition plans • Supply chain planning • Double materiality principle • External audit requirements | • Company + subsidiary + value chain due diligence • Human rights/environmental impact assessment • Climate transition plan implementation obligations |
Reporting Standards | ESRS (European Sustainability Reporting Standards) | No separate reporting standards; behavior-focused compliance |
Reporting Method | • Annual integration with financial reports • Limited assurance by external auditors | • Risk-based approach • Reasonable feasibility standard for measures |
Civil Liability | None | Yes (damage compensation claims possible) |
Supervisory Body | National authorities + external auditors | National supervisory authorities + judicial remedies |
International Standards | Aligned with GRI, ISSB, TCFD | Reflects OECD Guidelines, UN Guiding Principles (UNGP) |
The Omnibus Package: What’s Actually Changing
The package represents the EU’s effort to reduce reporting burdens by 25% for large companies and 35% for SMEs, while maintaining environmental policy objectives. The changes address practical implementation challenges that have emerged since the original directives were adopted.
CSRD: Adjusted Implementation Approach
The Corporate Sustainability Reporting Directive sees several modifications:
Timeline Adjustments:
- Companies with 500+ employees: Reporting timeline shifted from 2026 to 2028
- Listed SMEs: Implementation moved from 2027 to 2029
Scope Modifications:
- Reporting requirements now apply to companies with 1,000+ employees
- This adjustment affects approximately 80% of previously covered companies
Requirement Modifications:
- Sector-specific ESRS standards have been removed
- Companies with annual revenue under €450 million will report simplified Taxonomy metrics
- Enhanced protections implemented for SMEs through strengthened “Value Chain Cap” provisions
CSDDD: Refined Due Diligence Framework
The Corporate Sustainability Due Diligence Directive undergoes targeted adjustments:
- Indirect supply chain due diligence obligations have been modified
- Monitoring cycle requirements have been adjusted and stakeholder engagement scope refined
- Minimum penalty threshold requirements removed and civil liability framework updated
CBAM: Threshold-Based Simplification
The Carbon Border Adjustment Mechanism introduces a new threshold approach:
New Threshold Framework:
- Companies importing less than 50 tons annually of CBAM goods are excluded from obligations
- This modification affects approximately 90% of importers while maintaining coverage of 99% of emissions
Administrative Process Updates:
- Reporting deadline adjusted from May 31 to August 31
- CBAM registration agent system introduced for third-party delegation
- Verification requirements waived when using default values
Implications for Different Business Categories
Small and Medium Enterprises
For SME operations, the package introduces several notable changes. The Commission estimates administrative cost reductions of 25-35% for smaller companies, potentially allowing resource reallocation from compliance documentation to operational sustainability initiatives.
The new Voluntary SME Standard (VSME) provides an optional reporting framework that may facilitate responses to customer and financial institution sustainability inquiries without full mandatory CSRD compliance requirements.
Large Enterprises
For larger organizations, the two-year implementation delay provides additional time for sustainability management system development. However, EU climate policy objectives remain unchanged, and market-driven sustainability expectations from investors and customers continue to evolve.
Supply Chain Considerations
The enhanced protections for companies under 1,000 employees establish limits on information requests that larger corporations can make to smaller suppliers. This may reduce cascading compliance pressures experienced by SMEs in supply chains.
Unchanged Elements
Several fundamental aspects remain unmodified:
- The double materiality principle is maintained
- Core due diligence obligations under CSDDD continue
- Essential reporting requirement themes are preserved
- First-wave companies (currently reporting under NFRD) maintain existing obligations
Implementation Timeline and Process
Legislative Process Status
While timeline adjustments have been fast-tracked and approved, substantive modifications require European Parliament and Council approval through the ordinary legislative procedure. The complete legislative process may extend through the end of 2025.
Market Dynamics
Market-driven sustainability requirements continue independent of regulatory timelines. Customers, suppliers, and investors maintain sustainability expectations through commercial relationships. Organizations that establish robust sustainability practices may maintain competitive positioning regardless of regulatory evolution.
Future Regulatory Development
The Omnibus Package is positioned as the initial phase of a broader simplification initiative. Additional CBAM reviews are scheduled for 2025, with potential scope expansion to additional sectors under consideration.
Analysis: Policy Evolution and Business Response
The Omnibus Package reflects an adjustment period in EU sustainability policy development. The modifications indicate a recalibration of initial regulatory scope based on implementation feedback, particularly regarding smaller business impacts.
These changes represent a strategic refocusing toward larger organizations with more significant environmental footprints, while establishing graduated requirements for smaller entities. The approach maintains environmental policy objectives while addressing practical implementation challenges.
For organizations, the modifications provide additional preparation time for sustainability management system development. Companies that establish comprehensive sustainability practices during this period may be better positioned for future regulatory developments.
Conclusion
The EU Omnibus Simplification Package introduces significant modifications to the ESG compliance framework while maintaining core environmental policy objectives. The changes primarily affect implementation timelines, scope definitions, and administrative processes rather than fundamental sustainability requirements.
Organizations should consider these modifications within their broader sustainability strategy development, recognizing that market-driven sustainability expectations continue to evolve alongside regulatory requirements.
The Omnibus Package proposals are progressing through the EU legislative process. Timeline modifications have been expedited and approved, while substantive changes require European Parliament and Council approval. Updates will be provided as legislation develops.
