CSDDD vs CSRD due diligence and reporting compared

CSDDD scope is entity and turnover based. EU companies are covered when they exceed more than 1,000 employees and EUR 450 million net worldwide turnover, with parent-company and franchise/licensing variants. Non-EU companies are covered by EU turnover thresholds and related group or franchise/licensing conditions.

CSRD scope is tied to sustainability reporting status under the Accounting Directive as amended by CSRD. The Commission's grounding describes large undertakings, listed SMEs other than micro-undertakings, parent undertakings of large groups, issuers in those categories, and certain non-EU undertakings as reporting categories, with phased application.

A company can be in CSRD before, after, or without being in CSDDD. Run separate scoping checks and keep the assumptions visible: employee count, turnover, public-interest or listing status, parent-group status, EU branch or subsidiary facts, and any non-EU turnover facts.

CSDDD creates duties to conduct risk-based human rights and environmental due diligence. The core work is operational: integrate due diligence into policies, identify and assess adverse impacts, prioritise, prevent or mitigate potential impacts, end or minimise actual impacts, remediate, engage stakeholders, run complaints and notification channels, monitor effectiveness, and communicate.

CSRD modernises corporate sustainability reporting. The reporting work is to collect, verify, and publish sustainability information under Directive (EU) 2022/2464 and standards adopted for Directive 2013/34/EU.

Do not treat a CSRD report as proof that CSDDD due diligence has been performed. A report may describe due diligence, but CSDDD requires the underlying due diligence process and measures.

CSDDD uses the defined 'chain of activities': upstream business-partner activities linked to production or services, and certain downstream distribution, transport, and storage activities carried out for or on behalf of the company. It is not a generic entire-value-chain disclosure label.

CSRD reporting boundaries and disclosures are governed by the sustainability reporting framework and ESRS. Reporting evidence may include value-chain information, but that does not automatically match CSDDD's chain-of-activities definition.

Reuse supplier or site data only after checking that the same legal entity, operation, business partner, activity, geography, and impact are relevant to both the CSDDD chain-of-activities analysis and the CSRD disclosure.

CSDDD Article 16 requires companies to publish an annual statement on matters covered by the directive unless an exemption applies. It expressly says Article 16(1) does not apply to companies subject to sustainability reporting requirements under Articles 19a, 29a, or 40a of Directive 2013/34/EU, including specified exemptions.

CSRD is the reporting framework that amended Directive 2013/34/EU and empowered delegated and implementing acts. ESRS provides the sustainability reporting standards adopted under that framework.

For companies already subject to CSRD sustainability reporting, Article 16 is a coordination point, not a duplicate annual-statement workstream. Still keep the CSDDD due diligence evidence because the Article 16 reporting exemption does not remove Articles 7-15 due diligence duties or Article 22 transition-plan duties where applicable.

CSDDD evidence should prove the operating process: due diligence policy, impact mapping, severity and likelihood prioritisation, prevention and corrective action plans, contractual assurances and verification, SME support decisions, stakeholder engagement, complaints, remediation, monitoring, and updates after significant change.

CSRD evidence should prove reportable sustainability information: data sources, materiality judgements, disclosures, controls over the sustainability statement, and alignment with the applicable ESRS requirements.

One dataset can feed both regimes, but the evidence pack needs two mappings: 'what did we do to identify and address impacts?' for CSDDD, and 'what did we disclose and why is it reportable?' for CSRD.

CSDDD timing now reflects Article 37 as amended by Directive (EU) 2025/794. Member States must transpose by 26 July 2027. The first application wave starts on 26 July 2028 for EU companies with more than 3,000 employees and more than EUR 900 million net worldwide turnover, and for third-country companies with more than EUR 900 million net turnover in the Union. Other Article 2 companies follow on 26 July 2029, with Article 16 communication dates tied to later financial years.

The CSRD grounding describes phased reporting by category: first-wave large public-interest entities reporting in 2025 for financial year 2024, second-wave other large undertakings reporting in 2026 for financial year 2025, third-wave listed SMEs reporting in 2027 for financial year 2026, and fourth-wave certain non-EU undertakings reporting in 2029 for financial year 2028. The same Commission proposal would postpone wave 2 and wave 3 by two years.

Use separate date registers. CSDDD implementation dates control due diligence readiness and Article 16 communication; CSRD dates control sustainability statements and reporting preparation. Treat Directive (EU) 2025/794 as the current adopted CSDDD timing amendment, while treating CSRD stop-the-clock changes as proposal-status unless a separate adopted CSRD amendment source is available.

CSDDD enforcement is through Member State supervisory authorities with powers to require information, investigate, order cessation, order remediation where appropriate, impose penalties, and take interim measures. Pecuniary penalties must be based on net worldwide turnover, with a maximum limit of not less than 5%. CSDDD also includes civil liability for specified failures to comply with Articles 10 and 11 where damage is caused.

CSRD is enforced through corporate reporting, audit/assurance, competent authority, and market-supervision mechanisms tied to sustainability reporting rules. The directly grounded source here supports delegated and implementing acts, ESRS, and reporting-standard implementation, not a CSDDD-style adverse-impact liability route.

Do not copy penalty or liability statements between regimes. CSDDD exposure follows due diligence failures and national transposition; CSRD exposure follows sustainability reporting duties and assurance/reporting controls.

Use CSDDD when the question is: what must the company do about actual or potential human rights or environmental adverse impacts in its operations, subsidiaries, and chain of activities?

Use CSRD when the question is: what sustainability information must the undertaking report, under which standard, for which financial year, and with what reporting controls?

Build one shared fact base, then maintain two outputs: an operating due diligence file for CSDDD and a reporting file for CSRD. Reuse only facts, not legal conclusions.

CSDDD Article 22 requires covered companies to adopt and put into effect a climate transition plan. Companies that report a transition plan under Articles 19a, 29a, or 40a of Directive 2013/34/EU are deemed to have complied with the CSDDD obligation to adopt a transition plan, and the plan must be updated every 12 months.

CSRD/ESRS can be the place where the transition plan is reported. That reporting link does not turn every ESRS climate disclosure into a CSDDD due diligence measure.

Connect the transition-plan owner to both workstreams, but label the evidence carefully: adoption and implementation evidence for CSDDD; disclosure and reporting-standard evidence for CSRD.
