The EU is navigating a significant legislative transition in sustainability reporting in 2026. Omnibus I has narrowed CSRD scope, ISSB alignment pathways are under exploration, and SFDR requirements remain in effect. Amid this regulatory flux, investors face increasing complexity: CSRD requires double materiality assessment, SFDR includes adverse impact indicators, and ISSB focuses on financial materiality. Understanding these different approaches and the data infrastructure required to support them is critical. This article clarifies what these changes mean for investors, particularly regarding the often-overlooked social dimension of ESG.
Understanding the regulatory frameworks
What is ISSB?
The International Sustainability Standards Board (ISSB) develops global sustainability disclosure standards. ISSB IFRS S1 requires companies to disclose sustainability-related risks and opportunities when they are financially material to enterprise value. The framework is currently researching which specific human capital dimensions will be included in future standards.
What is CSRD?
The Corporate Sustainability Reporting Directive (CSRD) is an EU regulation requiring companies to report on sustainability matters using detailed disclosure standards. CSRD applies to large EU companies and non-EU companies with substantial EU operations.
What is Omnibus I?
Omnibus I is a 2025 EU legislative package that simplified and narrowed CSRD scope. Fewer companies are now required to report, which reduces publicly available sustainability data even as investor demand for this information increases.
Financial materiality vs double materiality
Financial materiality identifies sustainability factors that can affect a company's financial performance, enterprise value, or cash flows. The focus is on how external factors affect the company. Example: workforce instability that drives higher turnover costs and disrupts operations.
Double materiality includes financial materiality and adds impact materiality. Impact materiality measures how the company affects society and the environment. CSRD requires double materiality assessment, while ISSB focuses on financial materiality only.
The distinction matters for data infrastructure. Investors operating across jurisdictions must support both approaches simultaneously. SFDR further adds principal adverse impact (PAI) indicators that measure portfolio-level effects on sustainability factors.
Why financial materiality changes the data requirement
Human capital is increasingly recognized as financially material, with research demonstrating correlations between workforce practices and financial outcomes:
- According to Deloitte's human capital report, companies that prioritize human sustainability, focusing on well-being, equity, and skill development, achieve 2.2% higher 5-year ROE.
- According to Moody's Ratings, effective labor management is increasingly recognized as a material factor in credit quality assessments. Strikes, labor disputes, and non-compliance with labor laws can lead to operational losses and reputational damage.
- JP Morgan found that companies that invest more in employee training and maintain lower turnover rates demonstrate significantly higher labor productivity.
Despite these initial signals, there is no comprehensive baseline establishing which human capital factors are financially material across sectors and geographies. This is why Denominator is developing research to analye human capital performance and financial outcomes across millions of companies globally.
ISSB is currently researching which human capital dimensions may be included in future standards. While the framework requires disclosure of financially material sustainability factors, specific human capital metrics are still under development. This creates uncertainty for companies and investors about which dimensions will ultimately be required.
The EU alignment question and what it means for data infrastructure
In April 2026, the European Commission signaled exploration of a route for companies to comply with ISSB through CSRD reporting, provided financial and impact information are clearly distinguishable. If adopted, this pathway would allow portfolio companies to satisfy both CSRD and ISSB without producing separate reports.
Within this context, each company determines which human capital factors are material to their specific business and must provide supporting evidence. This requires rigorous analysis connecting sustainability metrics to financial outcomes.
The challenge: no comprehensive research baseline currently exists demonstrating which human capital factors correlate with financial performance across sectors and geographies.
Denominator's research addresses this gap. By analyzing human capital performance and financial outcomes across millions of companies globally, Denominator provides the evidential foundation that companies can reference when assessing their own materiality. Preliminary findings are expected in Q2 2026.
For investors, the research alone is not sufficient. Portfolio-level analysis requires operational data infrastructure: structured data across board, executive, and company levels; coverage of SFDR PAI dimensions; and standardization across jurisdictions. Denominator's Social Model provides 70 scores across four pillars built from 175+ underlying data points, differentiated from broad aggregated ESG ratings that lack methodological transparency or sufficient granularity.
What the regulatory landscape means for portfolio management
For institutional investors, including asset managers and pension funds, this creates a near-term data infrastructure question. Relying solely on CSRD disclosures will leave portfolio coverage gaps, as Omnibus has reduced the number of companies required to report.
Investors need granular, structured human capital data that covers SFDR PAI social indicators and provides sufficient detail to support financial materiality assessments at company level, regardless of whether individual portfolio companies fall within CSRD scope.
The data question ahead
Regulatory complexity around financial materiality is accelerating, but data availability is contracting due to narrower CSRD scope. Investors who establish data infrastructure now that addresses ISSB financial materiality requirements, SFDR PAI indicators, and potential CSRD-ISSB alignment pathways will be positioned as frameworks stabilize.
The question for portfolio management is no longer whether human capital data matters. The question is whether the data infrastructure in place can demonstrate financial materiality under the standards that are now being implemented.
