First Wave of CSRD Reports
The first wave of corporate sustainability reports under the European Union’s Corporate Sustainability Reporting Directive (CSRD) is now entering the public domain. As large companies publish their initial reports aligned with the European Sustainability Reporting Standards (ESRS), regulators, investors, and corporate practitioners are gaining their first real look at how organizations are implementing the directive’s most distinctive concept: double materiality.
For many companies, the first reporting cycle has been a significant learning process. Early disclosures reveal both promising practices and common implementation challenges—particularly around the “inside-out” dimension of double materiality, which requires companies to assess and report their impacts on the environment and society.
As the next group of organizations—often referred to as Wave 2 companies—begin preparing for their own CSRD reporting deadlines in 2026, these early reports offer valuable insights. By examining how the first wave approached double materiality assessments, companies can refine their own methodologies and avoid common pitfalls.
Understanding these lessons will be important not only for compliance but also for building credible sustainability reporting frameworks that meet the expectations of regulators and stakeholders.
Understanding the Double Materiality Principle
At the heart of the CSRD framework is the concept of double materiality, which expands traditional financial reporting perspectives.
Historically, companies have focused on financial materiality—identifying sustainability issues that may affect the company’s financial performance or enterprise value. The CSRD retains this dimension but adds an equally important second perspective.
Under double materiality, companies must also assess impact materiality, sometimes described as the “inside-out” perspective. This requires organizations to evaluate how their activities affect environmental and social systems, regardless of whether those impacts immediately influence financial performance.
In practical terms, the double materiality assessment asks two separate but related questions:
- Financial perspective (outside-in):
Which sustainability issues could materially affect the company’s financial position, performance, or future prospects? - Impact perspective (inside-out):
Which environmental or social impacts does the company cause, contribute to, or are directly linked to through its activities or value chain?
Only when both dimensions are considered together can organizations determine which sustainability topics are considered material under the CSRD framework.
Early Observations from the First Wave of Reports
With the first CSRD-aligned reports now emerging, several patterns are beginning to appear across industries. While implementation approaches vary, certain challenges appear consistently.
Many companies have invested substantial effort into building double materiality assessments. However, the first reporting cycle reveals that translating the concept into operational processes can be complex.
Among the most frequently observed challenges are:
- Overreliance on high-level scoring systems without sufficient methodological transparency
- Limited integration of value chain data, particularly beyond Tier-1 suppliers
- Insufficient documentation of how impact severity and likelihood were evaluated
- Difficulty distinguishing between risk exposure and actual societal or environmental impact
These issues do not necessarily indicate non-compliance, but they do highlight the practical difficulties companies face when applying the double materiality concept in real-world reporting contexts.
The “Inside-Out” Reporting Challenge
One of the most significant hurdles for many first-wave reporters has been the impact materiality assessment.
Unlike financial materiality—where established accounting frameworks and risk assessment tools exist—impact materiality requires companies to analyze the effects their activities have on external systems such as ecosystems, communities, and human rights.
This analysis often requires a combination of qualitative judgment and quantitative indicators.
For example, companies may need to evaluate:
- greenhouse gas emissions across their value chain
- impacts on biodiversity or natural resources
- labor conditions within supplier networks
- community impacts associated with production or infrastructure
Many first-wave companies have struggled with defining clear methodologies for evaluating impact severity, scale, and irremediability, which are core criteria referenced in international sustainability standards.
As a result, some early reports present materiality matrices without fully explaining how the underlying impact evaluations were conducted.
The Importance of Value Chain Visibility
Another common challenge relates to value chain coverage.
Under the CSRD and ESRS framework, companies are expected to consider impacts across their entire value chain—not just within their own operations. This includes upstream suppliers as well as downstream product use and disposal where relevant.
For organizations with complex global supply chains, obtaining reliable data across these networks can be difficult.
Several first-wave reports indicate that companies relied on proxy data or sector-level risk assessments where direct supplier information was unavailable. While this approach is acceptable during early implementation stages, regulators and auditors may expect increasing precision in future reporting cycles.
For Wave 2 companies, this highlights the importance of starting early on supply chain engagement and data collection processes.
Documentation and Methodological Transparency
One of the key lessons from the first reporting cycle is the importance of clear documentation.
The CSRD does not prescribe a single methodology for conducting double materiality assessments. However, companies must be able to demonstrate how their conclusions were reached.
Early reports vary significantly in the level of methodological detail provided. Some organizations offer detailed explanations of stakeholder engagement processes, scoring methodologies, and decision thresholds. Others present materiality results with limited supporting information.
As regulatory scrutiny increases, companies that provide transparent documentation of their assessment processes will likely be better positioned during audits or assurance reviews.
Stakeholder Engagement: An Essential Component
The CSRD framework places strong emphasis on stakeholder engagement as part of the materiality assessment process.
Stakeholders may include:
- employees
- customers
- suppliers
- local communities
- investors
- civil society organizations
Their input can help companies identify impacts that may not be immediately visible through internal analysis alone.
In the first wave of reports, stakeholder engagement practices vary widely. Some companies conducted extensive surveys or workshops involving diverse stakeholder groups, while others relied primarily on internal expertise.
For organizations preparing for upcoming reporting cycles, establishing structured stakeholder engagement processes can strengthen the credibility of double materiality assessments.
A Practical Checklist for Wave 2 Companies
As Wave 2 companies begin preparing for their own CSRD reports, several practical steps can help strengthen double materiality assessments.
1. Define a Clear Methodology
Companies should establish documented methodologies for assessing both financial and impact materiality. This includes defining criteria for evaluating impact severity, likelihood, and scale.
2. Map the Value Chain Early
Understanding the structure of upstream and downstream value chains is essential for identifying potential impacts. Early mapping efforts can help prioritize areas where deeper data collection is required.
3. Integrate Cross-Functional Expertise
Double materiality assessments often require input from multiple departments, including sustainability, risk management, procurement, legal, and finance.
Cross-functional collaboration helps ensure that both impact and financial perspectives are adequately captured.
4. Engage Stakeholders Systematically
Stakeholder engagement should be structured and documented. Surveys, interviews, and workshops can provide valuable insights into perceived impacts and risks.
5. Document Decision-Making Processes
Organizations should maintain clear records of how material topics were selected, including scoring methodologies and rationale for final decisions.
6. Plan for Continuous Improvement
The first CSRD report is unlikely to represent a final or perfect system. Companies should treat the process as iterative, refining methodologies and data sources over time.
The Role of Assurance and Regulatory Scrutiny
Another important factor influencing the next wave of CSRD reports is the role of external assurance.
CSRD requires companies to obtain independent verification of their sustainability disclosures. While the initial phase involves limited assurance, regulatory expectations may become stricter over time.
Auditors reviewing CSRD reports will likely examine not only the final disclosures but also the processes used to determine material topics.
Companies that build robust and transparent double materiality frameworks from the outset may find it easier to meet assurance requirements.
Moving Toward “Double Materiality 2.0”
The lessons emerging from the first wave of CSRD reports are already shaping how companies approach sustainability reporting.
Organizations are moving toward what might be described as Double Materiality 2.0—a more mature phase of implementation where assessments become increasingly data-driven, integrated with enterprise risk management systems, and supported by stronger supply chain visibility.
In this next phase, companies are likely to place greater emphasis on:
- improved value chain data collection
- integration of sustainability metrics into strategic planning
- alignment between sustainability reporting and financial risk management
- enhanced transparency in methodology and decision-making
This evolution reflects the broader goal of the CSRD: to ensure that sustainability considerations are embedded within corporate governance and strategic decision-making.
Looking Ahead
The first CSRD reporting cycle represents an important milestone in the evolution of corporate sustainability disclosure. For the companies that have already published their reports, the process has required significant organizational change.
For those preparing to report in the coming years, the experiences of the first wave offer a valuable opportunity to learn and improve.
By studying early implementation challenges—particularly around impact materiality, value chain coverage, and methodological transparency—Wave 2 companies can strengthen their own reporting frameworks before their 2026 deadlines.
Ultimately, the goal of double materiality is not simply to generate additional disclosures. It is to provide a clearer understanding of how companies interact with the environmental and social systems that support long-term economic activity.
As CSRD reporting continues to evolve, organizations that approach double materiality as a strategic management tool—rather than just a compliance requirement—will be better positioned to navigate the rapidly changing landscape of sustainability governance.
