CSRD Double Materiality in Practice: First Full Reporting Cycle Lessons for EU Chemical Companies

The first full reporting cycle under the Corporate Sustainability Reporting Directive (CSRD) has shifted attention from compliance to execution. Across the European chemical industry, companies are no longer explaining what double materiality means. Instead, they are showing how they identified material topics, collected sustainability data and addressed reporting challenges throughout the process.

For procurement managers, chemical traders and industrial buyers, these disclosures provide practical insight into supplier governance and reporting maturity. The strongest reports reveal not only sustainability priorities but also the quality of internal processes that support long-term business resilience.

How Companies Applied Double Materiality in Practice

The first reporting cycle shows that most chemical companies invested significant effort in building structured materiality assessments rather than relying on existing sustainability frameworks.

Many organizations described detailed methodologies that combined financial materiality with impact materiality. Instead of treating environmental, social and governance topics independently, companies assessed how sustainability issues affected enterprise value while also measuring the company's impact on people and the environment.

Several common practices appeared across published reports:

• Cross-functional workshops involving sustainability, finance, operations, procurement and risk management teams.

• Structured stakeholder engagement with customers, suppliers, employees, investors and regulators.

• Formal scoring systems used to rank sustainability topics according to business relevance and societal impact.

• Governance reviews to validate final materiality decisions before board approval.

These disclosures gave readers greater confidence in how material topics were selected.

Methodology Transparency Became a Key Differentiator

One of the clearest lessons from the first reporting cycle is that reporting quality depends heavily on methodology transparency.

The strongest reports explained each stage of the assessment process. Companies outlined stakeholder selection, evaluation criteria, scoring methods and governance oversight, allowing external readers to understand how conclusions were reached.

Less detailed reports often presented only the final list of material topics without explaining how decisions were made. While these reports met basic disclosure expectations, they offered limited insight into the strength of internal governance.

For procurement teams, methodology transparency provides an additional indicator of supplier maturity beyond headline ESG commitments.

Data Gaps Remain One of the Biggest Reporting Challenges

Although companies expanded sustainability disclosures significantly, many acknowledged that complete datasets were not yet available across every reporting area.

Supply chain information emerged as one of the most common challenges. Collecting consistent environmental and social data from hundreds or thousands of suppliers requires systems that many organizations continue to develop.

Companies frequently highlighted gaps involving:

• Upstream supplier emissions.

• Scope of environmental performance across complex supply chains.

• Human rights information from indirect suppliers.

• Biodiversity indicators.

• Product lifecycle data.

• Historical information needed for trend analysis.

Rather than hiding these limitations, many reports explained improvement plans and timelines for strengthening future disclosures.

Assurance Readiness Is Still Evolving

Independent assurance became another major focus during the first reporting cycle.

Many chemical companies described significant efforts to strengthen internal controls before submitting sustainability information for external review. This included improving documentation, standardizing data collection and assigning clear ownership for reporting responsibilities.

Organizations also reported challenges such as inconsistent source data, varying reporting systems between business units and limited historical information for certain sustainability indicators.

These experiences suggest that assurance is becoming more than a compliance exercise. It increasingly serves as a driver for stronger governance and better data management.

Supply Chain Reporting Is Receiving Greater Attention

Double materiality has expanded the role of procurement within sustainability reporting.

Many companies disclosed stronger engagement with suppliers to improve data quality and strengthen visibility across the value chain. Supplier questionnaires, sustainability assessments and digital reporting platforms appeared frequently as organizations worked to collect more reliable information.

For buyers, this trend means sustainability reporting increasingly reflects supplier performance as well as internal operations.

Procurement teams should expect continued requests for environmental, social and governance data throughout commercial relationships.

Governance Quality Is More Visible Than Ever

The first reporting cycle also demonstrated that governance extends well beyond board oversight.

Companies described new reporting committees, executive accountability structures and cross-functional collaboration designed to support CSRD reporting requirements.

Strong governance disclosures commonly included:

• Clearly defined reporting responsibilities.

• Board involvement in approving material topics.

• Internal review procedures.

• Risk management integration.

• Regular updates to sustainability governance frameworks.

These practices improve reporting consistency while increasing confidence among investors and business partners.

Practical Lessons for Procurement Professionals

CSRD reporting creates new opportunities for supplier evaluation.

Instead of reviewing sustainability targets alone, procurement teams can now examine how suppliers manage reporting processes, identify material risks and improve data quality over time.

When comparing suppliers, buyers should pay attention to:

• The clarity of the disclosed methodology.

• Honest discussion of reporting limitations.

• Evidence of improving data systems.

• Independent assurance practices.

• Integration of sustainability into business governance.

These factors often indicate whether sustainability programs are becoming embedded within daily operations.

What Buyers Should Watch in the Next Reporting Cycle

The first full CSRD reporting cycle established an important foundation, but reporting practices will continue to mature.

Future disclosures are likely to include more complete supply chain data, stronger assurance processes and greater consistency across reporting metrics. Companies that invested early in governance, digital reporting systems and stakeholder engagement are well positioned to improve both reporting quality and operational transparency.

For procurement teams, the greatest value lies in reading beyond materiality matrices and headline commitments. The methodology, acknowledged data gaps and assurance approach often reveal far more about a supplier's long-term reliability than sustainability targets alone.
