How to navigate the EU CS3D: Mastering Corporate Sustainability Due Diligence Directive
The €50 billion compliance challenge is here: Why EU's new sustainability mandate is reshaping business strategy across Europe—and why early adopters will win.
Approved in April 2024, the EU's Corporate Sustainability Due Diligence Directive (CS3D) will impact over 16,000 EU companies and 4,000 non-EU businesses operating in the European market, transforming how organisations approach human rights and environmental practices.
In this article, we'll break down everything you need to know about CS3D compliance, from implementation timelines to practical steps for building your transition plan—ensuring your business isn't just compliant, but strategically positioned for success.
Understanding the EU CS3D: Fundamentals of Corporate Sustainability Due Diligence Directive
The Corporate Sustainability Due Diligence Directive (CS3D) is a new EU legislative measure aimed at requiring companies to embed processes and policies that assess and manage risk and adverse impacts to human rights and the environment into business.
While compliance may not be required until mid-2027, understanding what the CS3D entails and taking steps now to align with its requirements will allow for lower compliance costs later down the road, and set you up as a forward-thinking leader.

CS3D scope: Who needs to comply across the EU
The CS3D will phase in gradually, applying first to the largest companies and then reaching medium and, eventually, smaller enterprises. It also affects non-EU companies that do substantial business within the bloc.
Thresholds are based on worldwide employee numbers and global turnover, and parent companies’ figures count towards these totals.
However, the EU Commission's recent Omnibus proposal could impact CS3D implementation by harmonising sustainability reporting standards and streamlining compliance procedures across multiple directives.
Companies should monitor developments closely as these changes may affect your transition plan timelines and resource allocation.
CS3D implementation timeline
The three-phase rollout of CS3D follows a strategic "cascade approach" to give businesses of different sizes adequate time to adapt their operations and supply chains.
2027: First wave implementation
EU-based companies with >5,000 employees globally and >€1.5 billion global turnover
Non-EU companies with >€1.5 billion turnover within the EU
2028: Second phase rollout
EU-based companies with >3,000 employees globally and >€900 million global turnover
Non-EU companies with >€900 million turnover within the EU
2029: Full compliance requirements
EU-based companies with >1,000 employees globally and >€450 million global turnover
Non-EU companies with >€450 million turnover within the EU
Franchisors with annual franchise fees >€22.5 million and turnover >€80 million (for non-EU franchisors, the EU turnover applies for these thresholds)
As each new threshold comes into effect, more companies will be brought under the CS3D’s umbrella.
Preparing early will give your organisation the lead time needed to adjust policies, systems, and supplier relationships.
CS3D objectives and requirements across the EU
The CS3D covers a broad scope of human rights and environmental protections, including but not limited to:
Human Rights
Safeguards against forced labor, child exploitation, and violations of workers’ fundamental rights. It also encompasses rights to adequate housing, food, clothing, sanitation, privacy, freedom of thought and religion, and the highest attainable standard of health—especially regarding children.
Environmental Protections
Preservation of biodiversity and natural habitats, preventing the trade of endangered species, proper handling of toxic substances and pesticides, protecting the ozone layer and wetlands, and preventing pollution in marine and other ecosystems.
By setting a high standard for due diligence across these areas, the CS3D aims to eliminate the most egregious abuses from global supply chains, ensuring that economic growth is no longer achieved at the expense of human dignity or environmental integrity.
Your company's CS3D obligations: Creating an effective transition plan
Companies falling within the CS3D’s scope will be required to:
1. Integrate Due Diligence into Corporate Policies: Incorporate human rights and environmental standards into your core policies and strategies, ensuring that these principles guide all business decisions.
2. Identify and Assess Adverse Impacts: Systematically examine your entire value chain—not just direct suppliers—to identify and assess actual and potential human rights and environmental risks.
3. Prevent, Mitigate, and Remediate: For potential harms, implement measures to prevent or reduce negative impacts. For actual harms, take steps to minimize damage and provide remedies to those affected.
4. Establish a Complaint Mechanism: Create accessible and transparent channels for anyone—employees, community members, NGOs, or other stakeholders—to report concerns and lodge complaints about your company’s impacts.
5. Monitor, Review, and Report: Continuously evaluate the effectiveness of your due diligence measures and integrate findings into annual disclosures, typically as part of the Sustainability Report required under the CSRD. Transparency is key, allowing regulators, investors, and the public to hold companies accountable.
What happens in the case of non-compliance?
Well, failure to comply with the CS3D will result in national authorities potentially levying fines, with maximum penalties reaching up to 5% of a company’s turnover.
In addition, civil liability for damages done to human rights or the environment along your supply chain, leading to potential lawsuits, legal fees, and reputational harm.
Beyond compliance: Strategic advantages of the CS3D framework
Adhering to the CS3D can yield substantial benefits:
1. Risk Reduction: Anticipating and addressing supply chain issues early helps you avoid costly disruptions, legal entanglements, and brand damage.
2. Investor Attraction: As investors increasingly value ESG performance, demonstrating compliance and a proactive stance can improve access to capital and shareholder confidence.
3. Enhanced Reputation: By showing genuine concern for human rights and the environment, you strengthen your brand, resonate with consumers, and attract top talent who seek employers sharing their values.
4. Long-Term Resilience: Building responsible, ethical supply chains positions your company for stable, long-term success amid evolving regulatory and market conditions.
Next steps: Preparing your CS3D transition plan
The CS3D is more than a regulatory hurdle—it’s a call to action for businesses to anchor their operations in respect for people and the planet.
By preparing proactively, establishing robust due diligence processes, engaging with stakeholders, and reporting transparently, your company can not only meet the CS3D’s requirements but also differentiate itself as a leader in sustainable and responsible business.
Start your preparations now to navigate this changing landscape effectively, turn compliance into a strategic advantage, and contribute positively to a more just, equitable, and sustainable global economy.
