Double Materiality Assessment
Conduct rigorous double materiality assessments as required by CSRD and ESRS — combining impact materiality and financial materiality into one structured process.
Double materiality is the foundation of CSRD reporting. ESG:ONE guides you through the full methodology, from stakeholder engagement to IRO identification and ESRS topic determination.
Book a DemoWhy Double Materiality Is Difficult
CSRD requires companies to assess materiality from two perspectives — the impact of the company on the world, and the financial effects of sustainability matters on the company. Most organisations have never done this before.
The ESRS methodology for double materiality is complex, requiring assessment of both impact materiality and financial materiality across all sustainability topics
Stakeholder engagement is a mandatory input but most companies lack structured processes for gathering, weighting and incorporating stakeholder views
Identifying and assessing Impacts, Risks and Opportunities (IROs) requires cross-functional input from sustainability, finance, risk and operations teams
The outcomes of double materiality directly determine which ESRS standards and data points must be reported — getting it wrong cascades through the entire disclosure
Documentation and evidence requirements are extensive, as the assessment must be auditable and defensible to assurance providers
Existing single-materiality approaches are insufficient and cannot simply be adapted — the financial materiality lens requires fundamentally different analysis
