Under the Corporate Sustainability Due Diligence Directive (CSDDD), the European Union requires the largest companies operating in the EU to identify, prevent and mitigate human rights and environmental harms across their own operations, their subsidiaries and their wider chain of activities.
Following the EU’s Omnibus I amendments, the directive applies to companies with at least 5,000 employees and 1.5 billion euros in net worldwide turnover. Non-EU companies are caught on turnover alone: the same 1.5 billion euros, but generated inside the EU, and with no employee threshold. Even companies below those thresholds are feeling the pull: in-scope customers are already pushing due diligence requirements down through their supply chains.
So which CSDDD software are companies — in scope or preparing to be — using for data collection, reporting and due diligence?
Below you’ll find some of the CSDDD tools that stand out from the crowd, along with their top features and indications for optimal use:
1. Tracera
Top CSDDD-related features:
- Detailed supplier sustainability questionnaire: An extensive and tailored questionnaire lets you ensure suppliers meet all necessary sustainability criteria, giving your company more confidence in suppliers’ compliance with due diligence requirements.
- AI-powered automated questionnaire completion: Rather than requiring suppliers to fill out the questionnaire manually, our AI technology reviews and interprets policy documents, automatically filling in most of the responses for them, reducing time spent and the risk of human error.
- Supplier portal for streamlined communication: A dedicated portal lets suppliers upload necessary documents, track progress, and view requirements. This eliminates the need for cumbersome email exchanges, keeping all communications centralized in one platform.
- Sustainability manager dashboard: A detailed dashboard allows sustainability managers to track and monitor due diligence completion across multiple suppliers, offering insights into progress, gaps, and areas for improvement in real time.
Best use case: By integrating Tracera into your workflow, your organization can automate and speed up the entire supplier due diligence process for compliance with CSDDD while ensuring effective communication with stakeholders and data management—beyond the CSDDD.
None of the other CSDDD solutions match the level of integration and automation Tracera brings. If you’re looking for a comprehensive tool that handles everything from data collection to automated reporting, this is the one.
And the best part is you can use Tracera to report on any other frameworks, directives, and organization policies like the CSRD, the EU Taxonomy, IFRS S2 and more.
2. GAN Integrity
Top features:
- Third-party risk management: Assesses and monitors risks posed by third-party relationships while conducting due diligence obligations.
- Policy management: Automates processes such as policy issuance and attestation.
- Incident management: Designed for the reporting, investigation, and resolution of compliance breaches and regulatory incidents.
- Training management: Plans and checks compliance training programs while ensuring that everyone has received instruction on applicable legislation and company policies.
Best use case: GAN Integrity primarily focuses on ensuring complete risk management which can be used for dozens of use cases including CSDDD compliance, compliance investigations, and whistleblowing compliance.
3. Sourcemap
Top features:
- Supply chain mapping: Registers suppliers and collects information on upstream supply chains.
- Supplier watchlist monitoring: Scans the supplier map against a watchlist of more than 80,000 entities.
- Scope 3 carbon reporting: Gathers information from sub-suppliers to calculate scope-3 emissions.
- Risk mapping: N-Tier Risk Mapping assigns risk scores for the extended supply chain by mapping every facility against authoritative risk heat maps for social, environmental, and operational risks.
- Tariff management and customs compliance: Collect transaction documents for every tier and assemble complete chain of custody. Proven with automotive OEMs, semiconductor and solar manufacturers and the world’s largest infrastructure suppliers.
Best use case: Sourcemap specializes in supply chain mapping and transparency, enabling compliance with directives such as the CSDDD by providing detailed insights into supply chains.
4. TrusTrace
Top features:
- Supplier mapping: Supports a wide variety of use cases including tracking and regulating supplier data, ESG metrics, facility profiles, scope certificates, audits, and assessments on a defined platform.
- Due diligence framework: Reduces the complexity of standardized processes with automated workflows and a risk-based approach.
- Certified material compliance: Automates the digitalization of supplier certificate data, creating a digital chain of custody down to the percentage of certified materials.
In February 2026, TrusTrace launched the One Retail Hub with seven European retailers including Zalando Group, ASOS and New Look, developed alongside Cascale and Fair Wear. The free platform hosts a single 51-question due diligence questionnaire built on the OECD Due Diligence Guidance, so a brand answers once instead of filling in a separate form for every retailer.
Best use case: TrusTrace is a CSDDD software better used by brands in the fashion and footwear space that need to ensure compliance with CSDDD as it provides the features needed to support materials claims and relieve some risks in textile value chains.
5. Greenscope
Top features:
- ESG data management: Supports the collection, management, and reporting of environmental, social, and governance data to ensure compliance with regulatory requirements.
- Impact analysis and compliance: Best used for a diversity of use cases including addressing all your environmental impacts, staying up-to-date with current regulation changes, and accessing preferred financial conditions.
- Carbon assessment: Track your entire value chain to assess the main areas of greenhouse gas emissions under Scope 1-2-3.
Best use case: Greenscope is an ESG data and reporting platform for private market investors, funds and financial institutions rather than a dedicated due diligence tool. It’s worth a look if your CSDDD exposure comes through a portfolio or through investor reporting, and if you also need CSRD double materiality and financed emissions in the same place.
Key features that support CSDDD compliance reporting
To meet CSDDD compliance requirements, companies must ensure that the following main components are included in their CSDDD tool:
- Supply chain transparency: Your CSDDD software of choice should identify and map suppliers across the chain of activities, check compliance with human rights and environmental standards and provide ongoing risk monitoring. The Omnibus amendments let companies prioritize direct business partners when assessing risk areas, and require that information requests be proportionate, so a tool that can scope and tier suppliers matters more than one that simply collects everything.
- Risk management and due diligence: Seek features like risk assessments for human rights violations, environmental impacts, and corporate ethics as well as mitigation plans for risks and non-compliance issues.
- ESG data collection and analysis: Opt for a CSDDD platform that lets you track and document sustainability efforts for organizations and supply chains, automate data collection, and, as an added bonus, rely on AI for data validation and compliance verification.
- Policy and legal compliance: Aligning with international regulations is one critical aspect such platforms should support alongside due diligence reporting and the management of all legal documentation for running compliance checks.
- Reporting and audit readiness: Automated reporting can save you time and prevent human-related inaccuracies. Add in audit trails and dashboards for real-time compliance monitoring and you’re set to have a fully transparent grasp of what’s going on within your organization and with suppliers.
