The EU Omnibus Regulation

  • The EU “Omnibus” package refers to a series of legislative initiatives launched by the European Commission in 2025 to simplify and streamline EU rules, particularly in the areas of sustainability reporting, corporate due diligence, sustainable finance and carbon-border measures.

    Announced on 26 February 2025, the first Omnibus package proposed targeted amendments to several existing EU laws, including the Corporate Sustainability Reporting Directive (CSRD), Corporate Sustainability Due Diligence Directive (CSDDD), EU Taxonomy Regulation and Carbon Border Adjustment Mechanism (CBAM). Related measures also address EU investment programmes such as InvestEU.

    The initiative forms part of the Commission’s broader Competitiveness Compass and simplification agenda, which aims to reduce administrative burdens, improve the business environment and strengthen EU competitiveness while maintaining the EU’s core climate and sustainability objectives.

    Importantly, the Omnibus is not a single regulation. It is a package of legislative amendments and related measures, which have followed different legislative processes and entered into force at different times. Some of the proposed changes have now been adopted, while other measures continue to be implemented or reviewed separately.

  • The EU Omnibus package’s core objectives are to simplify compliance, reduce administrative burdens and strengthen EU competitiveness while maintaining the EU’s broader climate and sustainability objectives. Key aims include:

    • Reduce Administrative Burdens: Simplify and streamline reporting, due diligence and other regulatory requirements, reducing unnecessary administrative costs for companies and public authorities, particularly SMEs.

    • Enhance Competitiveness and Investment: Create a more predictable and proportionate business environment that supports companies in investing, innovating and growing within the EU.

    • Streamline Overlapping Rules: Improve consistency between related EU sustainability frameworks, reducing duplication and unnecessary reporting or data requirements.

    • Focus on Proportionality: Concentrate mandatory sustainability obligations on the largest companies while limiting disproportionate requirements on smaller companies and business partners in value chains.

    • Maintain Climate and Sustainability Objectives: Simplification is intended to preserve the EU’s core environmental and social objectives while making the regulatory framework more efficient and workable for businesses.

    • Improve Regulatory Certainty: Provide companies with clearer requirements, longer implementation periods where appropriate and a more stable basis for planning compliance and investment.

  • The EU Omnibus package covers several areas of EU sustainability and economic regulation. The most significant measures for companies include:

    • Corporate Sustainability Reporting (CSRD): The Omnibus I amendments significantly narrow the mandatory CSRD scope to companies with more than 1,000 employees and more than €450 million in net annual turnover. Reporting requirements have also been simplified, including a substantial reduction in mandatory sustainability datapoints. Companies outside the mandatory scope may use a new voluntary sustainability reporting standard, while information requests from larger companies to smaller value-chain partners are subject to safeguards. The European Commission adopted revised ESRS in July 2026, which further streamline the reporting requirements and reduce the number of datapoints companies need to report.

    • Corporate Sustainability Due Diligence (CSDDD): The revised CSDDD focuses mandatory due diligence requirements on very large companies with more than 5,000 employees and more than €1.5 billion in net annual turnover. The framework has been made more risk-based, allowing companies to prioritise areas where adverse impacts are most likely or severe. It also reduces the burden on smaller business partners by limiting disproportionate information requests and introduces a more targeted approach to companies’ chains of activities.

    • EU Taxonomy: The Omnibus package simplifies Taxonomy reporting and reduces the number of companies required to provide mandatory disclosures. The Commission has also introduced greater flexibility and simplified reporting templates to make Taxonomy reporting more proportionate. Companies outside the mandatory scope may report voluntarily.

    • Carbon Border Adjustment Mechanism (CBAM): The CBAM simplification introduces a 50-tonne annual de minimis threshold for importers of CBAM-covered goods. Importers below this threshold are generally exempt from CBAM obligations, while the mechanism continues to cover the vast majority of embedded emissions. The rules also simplify authorisation, emissions calculations and other compliance procedures.

    • EU Investment Programmes: Related Omnibus measures simplify EU investment instruments, including InvestEU, with the aim of making funding more accessible and reducing administrative complexity for implementing partners and beneficiaries. These measures form a related but distinct part of the Commission’s wider simplification and competitiveness agenda.

    Together, these measures are intended to create a more proportionate and coherent EU regulatory framework, with mandatory sustainability requirements increasingly focused on the largest companies while reducing indirect compliance burdens on smaller businesses.

    • 26 February 2025 – Omnibus I proposed
      The European Commission presented the first Omnibus simplification package, proposing changes to the CSRD, CSDDD, EU Taxonomy and CBAM, alongside related measures to simplify EU investment programmes.

    • April 2025 – “Stop-the-clock” adopted
      The EU adopted a separate “stop-the-clock” measure postponing certain CSRD and CSDDD deadlines, giving companies and Member States additional time while the substantive Omnibus amendments were negotiated.

    • 2025 – Legislative negotiations
      The European Parliament and Council developed their respective positions on the proposed changes, followed by negotiations between the EU institutions.

    • 9 December 2025 – Provisional agreement on Omnibus I
      The Council and European Parliament reached a provisional agreement on key amendments to sustainability reporting and due diligence requirements.

    • 24 February 2026 – Final approval of CSRD/CSDDD amendments
      The Council formally approved the Omnibus I amendments to the CSRD and CSDDD. The revised rules significantly narrow the scope of mandatory sustainability reporting and due diligence and introduce a more proportionate framework.

    • March 2026 – Revised CSRD/CSDDD framework enters into force
      The amending legislation entered into force following publication in the Official Journal. Member States must implement the revised requirements within the deadlines specified in the legislation.

    • 2026 – CBAM simplification takes effect
      The revised CBAM framework introduces the 50-tonne annual de minimis threshold and other simplifications for importers.

    • July 2026 – Revised ESRS adopted by the Commission
      The European Commission adopted revised European Sustainability Reporting Standards designed to make CSRD reporting shorter, clearer and more proportionate. The revised standards significantly reduce the number of datapoints required.

    • 2028–2029 – National implementation and application
      The revised CSRD and CSDDD frameworks will be implemented by Member States and become applicable according to the specific timelines established in the amended legislation. The revised CSDDD will apply from 26 July 2029.
