The Corporate Sustainability Reporting Directive (CSRD) is transforming the way companies disclose their environmental, social, and governance (ESG) performance.
While large corporations are already adapting, small and medium enterprises (SMEs) across Europe must also prepare. CSRD compliance for SMEs is no longer optional—it’s a critical component of doing business in the EU. With deadlines approaching and expectations rising, SMEs need to act now.
Here are the five most critical steps every SME should follow to achieve CSRD compliance in 2025.
-
Understand Your Legal Obligations and Timeline
The first step to CSRD compliance for SMEs is knowing where you stand legally. Although the CSRD initially applies to large companies, SMEs listed on regulated markets will need to comply starting in 2026. However, indirect pressures—such as from supply chain partners—mean many SMEs must act earlier.
You should:
- Determine if your SME falls under mandatory or voluntary reporting.
- Understand which year your reporting must begin.
- Familiarize yourself with the European Sustainability Reporting Standards (ESRS).
Early awareness will give you time to build a strategy rather than scramble at the last minute.
-
Conduct a Double Materiality Assessment
CSRD requires companies to evaluate sustainability through a double materiality lens—financial and impact-based.
This step helps SMEs:
- Identify ESG topics that affect business performance (financial materiality).
- Pinpoint areas where the business impacts society and the environment (impact materiality).
Use stakeholder interviews, internal workshops, and supply chain data to support your findings. This assessment forms the backbone of your sustainability strategy and reporting.
As Greenly emphasizes, failing to perform this step risks misreporting and non-compliance. It’s not just about ticking boxes—it’s about aligning your business with sustainable outcomes.
-
Build a Robust ESG Data Collection System
Accurate, verifiable data is at the core of CSRD reporting. SMEs must move away from spreadsheets and fragmented tools. Instead, invest in ESG software or platforms that centralize and automate data collection.
Key actions include:
- Establish clear Key Performance Indicators (KPIs) aligned with ESRS.
- Assign ESG data owners across departments.
- Set up periodic internal reviews for data quality.
According to Coolset’s 2025 CSRD roadmap, this step is essential for long-term compliance and credibility. Even basic systems can evolve over time—starting now is key.
-
Engage Stakeholders and Build Internal Awareness
Your compliance journey won’t succeed without internal and external buy-in. CSRD requires transparency, which means including stakeholders throughout the process.
To do this effectively:
- Train employees on sustainability concepts and reporting duties.
- Communicate with suppliers, clients, and investors about your CSRD strategy.
- Develop an internal governance structure for ESG reporting.
Seneca ESG advises starting this culture shift early. Transparency builds trust and helps embed sustainability into your core business model.
-
Develop and Publish Your First CSRD-Aligned Report
The final step is to compile your findings into your first CSRD-aligned sustainability report. This document must follow ESRS standards, be verified by an independent auditor, and be publicly available.
The report should include:
- A summary of your business model and ESG risks.
- Your double materiality assessment findings.
- Measurable KPIs and targets.
- Governance structures related to sustainability.
Remember to include forward-looking information. Reporting is not just a retrospective exercise—it’s a statement of future intent.
As Sweep’s 2025 insights highlight, publishing an initial report—no matter how simple—signals progress and commitment.
The Time for SMEs to Act Is Now
Complying with CSRD may feel overwhelming, but breaking it into structured steps makes the process manageable. CSRD compliance for SMEs starts with understanding legal obligations, conducting a double materiality assessment, organizing ESG data, engaging stakeholders, and publishing your report.
These five steps will not only ensure compliance but also position your SME as a responsible, forward-thinking business in an increasingly sustainability-driven market.
Now is the time to get started—because sustainability is not just a requirement, it’s a competitive advantage.
Take the Next Step: Equip Your Team for CSRD Success
While these five steps offer a practical starting point, achieving true CSRD readiness demands not only a deeper understanding but also continuous upskilling. Consequently, many SMEs are now turning to structured learning programs to effectively bridge the knowledge gap. For instance, the CSE’s flagship Certified Practitioner Program, Advanced Edition—taking place on June 25-26 & 27 by the Center for Sustainability & Excellence (CSE)—is designed specifically for professionals across Europe, including SMEs, who are eager to master the essentials of ESG and sustainability reporting under CSRD. By enrolling in this course, your team will be empowered with the tools, insights, and confidence needed to implement CSRD-aligned strategies that drive long-term value. Ultimately, this investment in learning supports both compliance and competitive advantage.
