CSRD Double Materiality Trends in 2026:
A Year-over-Year Review

Drawing on 20,844 IRO disclosures gathered
from the Datamaran platform across 300
companies, 21 countries, and 11 sectors, this
report presents year-over-year trends in how
double materiality assessments are evolving
across the first two CSRD reporting cycles.

So what do the findings show? Materiality scope is narrowing. Opportunity disclosures are declining. Entity-specific topics are rising fast. And for many organizations, the work of building a truly defensible, decision-useful double materiality assessment continues.

What the Data Reveals

Materiality is moving, but not in the direction you might expect.

88% of companies changed the number of material IROs they disclosed year-over-year. This reflects a market still actively recalibrating, with a split between those making incremental refinements and those undertaking fundamental reassessments.

Downside exposure still dominates disclosures.

Negative impact reporting increased across every ESRS topical standard. For organizations integrating sustainability disclosures into investor communications and risk reporting, a profile dominated by downside exposure raises important strategic questions.

Some of the most scrutinized topics are seeing less coverage, not more.

Biodiversity (E4), Water and Marine Resources (E3), Pollution (E2), and Affected Communities (S3) all saw declining reporting coverage in 2026. As stakeholder expectations in these areas intensify, the gap between disclosure practice and emerging requirements is widening.

Entity-specific disclosures are a growing area of CSRD reporting.

The share of companies reporting at least one entity-specific IRO doubled year-over-year. This signals that companies are using CSRD disclosures to surface material risks that existing ESRS standards do not yet fully address.
