Overview
The Corporate Sustainability Due Diligence Directive (CSDDD, EU 2024/1760) requires large companies operating in the EU to identify, prevent, mitigate, and account for adverse human rights and environmental impacts across their entire supply chain - not just their direct suppliers. The operative word is account for: companies must document that due diligence was conducted, that suppliers were assessed, and that the supply chain can be traced to its origin. That documentation must be audit-ready. ROOTKey provides the cryptographic traceability infrastructure that makes that documentation tamper-evident, multi-party verifiable, and independently auditable.Scope
| Phase | Timeline | Applies to |
|---|---|---|
| Phase 1 | From 2027 | Companies with >5,000 employees and >€1.5bn global net turnover |
| Phase 2 | From 2028 | Companies with >3,000 employees and >€900m global net turnover |
| Phase 3 | From 2029 | Companies with >1,000 employees and >€450m global net turnover |
| Non-EU companies | Same phased timeline | Non-EU companies meeting turnover thresholds in the EU market |
CSDDD Due Diligence Obligations and ROOTKey
Obligation 1 - Integrating Due Diligence into Policy
CSDDD requires companies to have a due diligence policy that is updated annually and describes the approach to supply chain assessment. ROOTKey anchors:- Policy documents at each version approval - tamper-evident proof that the policy existed and was approved at the stated time
- Supplier code of conduct documents - verifiable proof of the terms communicated to suppliers
Obligation 2 - Mapping the Supply Chain and Identifying Risks
Companies must identify actual and potential adverse impacts across operations, subsidiaries, and business partners. ROOTKey supports:- Anchoring supplier assessment records - proof that assessments were conducted and when
- Multi-tier supply chain mapping - vaults that span multiple supply chain parties, creating a shared tamper-evident record of the supply chain structure
Obligation 3 - Preventing and Mitigating Adverse Impacts
Where impacts are identified, companies must take preventative and corrective actions and document them. ROOTKey provides:- Anchored corrective action plans - proof of what was committed and when
- Follow-up audit records - immutable evidence that remediation was conducted and its outcome
Obligation 4 - Establishing a Complaints Procedure
Companies must provide a complaints mechanism for affected parties and business partners. ROOTKey can anchor:- Complaint receipt records - independently timestamped, preventing dispute over whether a complaint was received
- Response and resolution records - complete audit trail of the complaints lifecycle
Obligation 5 - Monitoring the Due Diligence Framework
Companies must monitor the effectiveness of their due diligence measures. ROOTKey’s Analytics API supports continuous monitoring of anchoring activity - detecting gaps in coverage that might indicate lapses in due diligence documentation.Multi-Party Supply Chain Architecture
CSDDD compliance requires documentation that crosses organisational boundaries - your Tier 1 suppliers, their Tier 2 suppliers, and beyond. Traditional documentation systems require trust in each party’s records. ROOTKey vaults can accept anchors from multiple parties, building a shared, tamper-evident chain of custody that no single participant controls: → See also: Supply Chain Traceability use caseCompliance Mapping
| CSDDD Obligation | ROOTKey capability |
|---|---|
| Policy documentation | Anchored policy versions - tamper-evident, timestamped |
| Supplier assessment records | Anchored assessment documents per supplier |
| Corrective action plans | Anchored commitments with verifiable timeline |
| Complaints procedure evidence | Timestamped complaint receipt and resolution records |
| Supply chain traceability | Multi-party vault - custody chain verifiable by auditors |
| Annual reporting evidence | Full audit trail of due diligence activity for the reporting period |
Connection to Other EU Frameworks
CSDDD overlaps with other EU supply chain and sustainability obligations:| Framework | Connection to CSDDD |
|---|---|
| EU Deforestation Regulation (EUDR) | Supply chain traceability to point of production required - same ROOTKey architecture applies |
| EU Batteries Regulation | Due diligence and carbon footprint documentation for battery supply chains |
| CSRD | Corporate Sustainability Reporting Directive - CSDDD due diligence feeds CSRD sustainability disclosures; anchored evidence supports CSRD audit |
| NIS2 | ICT supply chain security (Art. 21(2)(d)) - CSDDD adds human rights and environmental dimensions to the same supply chain |
