How the EU’s CSRD is making D&I a mandated and regulated standard of business integrity

In the European Union, inclusion is no longer a corporate ideal – it’s a legal obligation. Sweeping new regulations have elevated diversity and inclusion (D&I) from aspirational values to measurable business standards, with mandatory disclosure requirements now written into law.

Under the Corporate Sustainability Reporting Directive (CSRD), more than 50,000 companies operating in or connected to the EU will soon be required to report on inclusion metrics with the same rigor as they do profits, emissions, or executive pay.

At the center of this transformation is the Corporate Sustainability Reporting Directive (CSRD), adopted in December 2022 and in force since January 2023. It replaces and expands the earlier Non-Financial Reporting Directive (NFRD), significantly widening the scope of companies required to disclose sustainability-related information.

The CSRD requires disclosures aligned with the newly developed European Sustainability Reporting Standards (ESRS), overseen by the European Financial Reporting Advisory Group (EFRAG). Specifically, ESRS S1 – Own Workforce mandates that companies report on key social metrics – including D&I – as part of their sustainability statements.

Large public-interest entities already subject to NFRD began reporting on their 2024 activities in 2025. Other large EU companies (with over 250 employees, €40M turnover, or €20M in total assets) are set to report from 2026, based on 2025 data. Listed SMEs will begin in 2027, with an optional deferral to 2028. Non-EU companies with significant EU activity (over €150M in annual EU revenue) are required to report from 2029.

The new inclusion reporting standards

The new standards demand both qualitative and quantitative disclosures. Companies must now publicly disclose:

• Gender and age distribution across all levels of the organization
• Pay structures and gender pay gaps
• Accessibility and disability inclusion
• Work-life balance policies and health & safety measures
• Training and upskilling access
• Collective bargaining coverage
• Inclusion strategies, targets, and time-bound KPIs

More importantly, the CSRD also requires that this data be subject to external assurance, meaning that it must be accurate, consistent, and auditable. The CSRD introduces limited assurance starting in 2025, with a planned shift to reasonable assurance within three years, depending on further regulatory developments. You can view the official ESRS S1 Standard here.

How to comply

While the shift to mandated D&I reporting is significant, compliance is achievable if companies act proactively. Here are the most important steps businesses should take:

• Conduct a double materiality assessment to determine whether and how workforce-related issues are material from both a financial and societal perspective. This is required under Article 29b of the CSRD Directive as amended by the CSRD, and further detailed in ESRS 1 General Requirements.
• Audit existing D&I data across HR systems, finance, and operations. Identify what’s already being tracked (e.g. gender ratios) and where gaps exist (e.g. disability representation or wage transparency).
• Implement structured data collection processes to gather the required metrics consistently across regions, subsidiaries, and employee types. This includes training hours, pay data, inclusion efforts, and contract types.
• Develop time-bound, measurable inclusion goals, such as gender parity in management or improved representation of underrepresented groups. These targets must be disclosed and linked to corporate strategy.
• Align governance structures, ensuring board oversight over ESG – and by extension, D&I – reporting. This includes integrating D&I into risk management frameworks and executive accountability.
• Prepare for external assurance by building an audit trail for all disclosed data. The CSRD specifies that sustainability reports must undergo limited assurance starting in 2025, with potential for reasonable assurance in later phases.
• Invest in ESG reporting tools that are compatible with ESRS formats. These platforms can centralize data collection, standardize disclosures, and streamline assurance workflows.

The consequences of non-compliance

Failure to comply with CSRD carries significant consequences. Each EU member state is responsible for implementing penalties, which may include financial sanctions and reputational damages. Non-compliant companies also risk losing credibility with ESG investors, clients, and regulators.

Additionally, sustainability reporting is becoming a competitive differentiator. Public and private sector buyers across the EU are increasingly using ESG disclosures – including D&I metrics – as procurement criteria. Inconsistent or incomplete reporting may disqualify companies from contracts or investment.

While the regulatory burden may feel heavy, forward-thinking companies are already recognizing the upside. Treating D&I as a data-driven, strategic function unlocks far more than compliance. It drives employee engagement, boosts innovation, and builds resilience.

A new standard for business success

As EFRAG’s consultation paper makes clear, D&I data is now critical to understanding how social capital contributes to long-term value creation. Businesses that embrace this shift will be better prepared to not only attract talent and satisfy stakeholders, but also better navigate social risk.

With the CSRD, the EU has done more than introduce another layer of ESG reporting. It has elevated D&I from a people issue to a performance issue, placing it firmly on the strategy table, next to margins, growth, and governance. If your organization is still treating inclusion as a side project or PR campaign, the time for change is now, as regulators, investors, and employees alike now require proof.
