Double Materiality

Double Materiality Assessment

Double Materiality Assessment Software, Built for CSRD Compliance

Stop managing your DMA in spreadsheets. EcoActive maps financial and impact materiality across all ESRS topics automatically — and produces the audit-ready documentation your assurance team needs.

What Is Double Materiality?

Double materiality is the CSRD assessment framework that determines which sustainability topics a company must disclose. It works across two lenses — and a topic only needs to clear one of them to trigger a reporting obligation.

INSIDE-OUT PERSPECTIVE

Impact Materiality

How do the company’s activities affect people, the environment, and society — across its full value chain? Covers actual and potential impacts, positive and negative.

OUTSIDE-IN PERSPECTIVE

Financial Materiality

How do sustainability issues create financial risks or opportunities for the company? Includes physical risks, transition risks, and sustainability-linked opportunities.

ESRS 1 | GENERAL REQUIREMENTS
What the Regulation Actually Requires

ESRS 1 sets a mandatory DMA methodology built around one core concept: the IRO framework — Impacts,
Risks, and Opportunities. Here is what companies are required to do.

Build a Long List

Identify potential impacts, risks, and opportunities across all ESRS topics — before applying any threshold.

Apply Severity Criteria

Assess impacts using scale, scope, and irremediable character, with likelihood considered for potential impacts.

Assess Financial Effects

Evaluate sustainability-related risks and opportunities that could affect cash flows, financing, or cost of capital.

Engage Stakeholders

Document input from affected parties and users of financial information — both groups are required under ESRS 1.

Set and Document Thresholds

Define, justify, and record the materiality thresholds applied. These are reviewed during limited assurance.

Map to Disclosure Obligations

Material topics determine which ESRS standards apply and which disclosure requirements the company must meet.

What You're Assessing Against: The Full ESRS Topic Universe

The DMA is conducted against every ESRS sustainability topic. Your material topics — drawn from this list — determine your ESRS disclosure scope under CSRD. Topics not identified as material can be omitted, but the methodology for that conclusion must be documented and defensible.

Pillar	Standard	Topics Covered
E1–E5	Environment	Climate change · Pollution · Water & marine resources · Biodiversity & ecosystems · Resource use & circular economy
S1	Own Workforce	Working conditions · Equal treatment · Health & safety · Social dialogue
S2	Value Chain Workers	Working conditions and rights among supply chain and downstream partners
S3	Affected Communities	Economic, social & cultural rights · Land rights · Security-related impacts
S4	Consumers & End-Users	Product safety · Personal data · Social inclusion · Information access
G1	Business Conduct	Anti-corruption · Corporate culture · Supplier relationships · Lobbying · Payment practices

HOW IT WORKS

The Double Materiality Assessment: Step by Step

ESRS 1 does not mandate a single methodology — but compliant assessments follow a consistent five-stage process.
Here is what that looks like in practice.

1. Understand Your Context

Define your business model, activities, geographies, and value chain scope — upstream and downstream.
This context determines what belongs on your long list.

2. Identify a Long List of IROs

Draw from all ESRS topics. Use sector guidance, peer benchmarks, and stakeholder input to build a comprehensive
long list. Omissions here create audit risk later.

3. Score and Assess

Apply severity and likelihood criteria for impact materiality. Apply likelihood and magnitude criteria for financial
materiality. Each IRO is scored against your defined thresholds.

4. Engage Stakeholders

Consider and document input from affected stakeholders and users of sustainability information, using proportionate
engagement methods appropriate to the company's context.

5. Conclude and Document

Produce a final list of material topics with documented rationale for inclusions and exclusions. Record governance
sign-off. This documentation is reviewed during limited assurance.

How EcoActive Automates Your Double Materiality Assessment

Most companies are still running their DMA in spreadsheets. EcoActive’s ESG reporting software replaces that with a structured,
ESRS-aligned workflow — built for speed, auditability, and governance from day one.

Pre-Loaded ESRS Topic Universe

All ESRS topics and sub-topics across E1–E5, S1–S4, and G1 are pre-loaded.
Your long list is structured from
the start.

IRO Scoring Engine

Apply severity, likelihood, and magnitude criteria within the platform. Materiality scores are calculated automatically with
full audit trail.

Stakeholder Engagement Workflow

Manage stakeholder engagement through surveys, interviews, workshops, or evidence uploads, with responses linked to IROs and retained for assurance.

Configurable Thresholds

Set your own materiality thresholds or adopt EcoActive defaults aligned with EFRAG guidance. Version-controlled and available for auditor review.

DMA to Disclosure Mapping

Confirmed material topics automatically generate your ESRS disclosure obligations — no manual cross-referencing,
no gaps.

Audit-Ready Documentation

Export your complete DMA record — methodology, scoring, stakeholder inputs, threshold rationale, governance sign-off — structured for limited assurance.

Does CSRD Apply to You? Scope and Reporting Timelines

The double materiality assessment is a mandatory requirement for all CSRD in-scope entities. Wave 1 companies have started
reporting under CSRD for FY2024. For Wave 2 and Wave 3 companies, the EU Stop-the-Clock Directive has postponed the
application dates by two years, while broader CSRD/ESRS simplification proposals continue to evolve.

Wave	Company Type	Reporting Timeline
Wave 1	Large listed EU companies (formerly in NFRD scope)	FY2024 reporting, first reports in 2025 Underway
Wave 2	Large EU companies not previously in NFRD scope	Deferred to FY2027 reporting, first reports in 2028 — subject to national transposition and any further scope amendments Active Cohort
Wave 3	Listed SMEs, small credit institutions, captive insurers	Deferred to FY2028 reporting, first reports in 2029 Upcoming
Art. 40	Non-EU companies with significant EU revenue	Still expected from FY2028 under current CSRD structure — monitor Omnibus changes Monitor

Wave 2 and 3 timelines are subject to final national transposition of the Stop-the-Clock Directive. Companies also subject to EU Taxonomy reporting should note that DMA conclusions also inform Taxonomy alignment assessments. Confirm all timelines at time of publication.

Why EcoActive for Double Materiality

01 Built Around ESRS 1

Not retrofitted from a generic survey tool. EcoActive’s DMA module is structured around the IRO framework and ESRS 1 methodology from the ground up.

02 Assurance-Ready by Design

Every threshold, score, and stakeholder input is logged with a full audit trail — so your assurance provider has what they need without additional prep.

03 Connected to Your Full Disclosure

The DMA does not sit in isolation. Material topics flow directly into your ESRS reporting scope — keeping your disclosure and your assessment in sync.

Frequently Asked Questions

What is the difference between double materiality and single materiality?

Single materiality — used by ISSB standards (IFRS S1/S2) — asks only whether sustainability issues affect the company financially. Double materiality adds a second dimension: how the company affects the world. Under CSRD, both must be assessed.

Is a topic in scope if it is only financially material, not impact material?

Yes. Under ESRS, a topic triggers disclosure obligations if it is material from either or both perspectives. Financial materiality alone is sufficient.

How long does a double materiality assessment typically take?

For first-time adopters working manually, 3 to 6 months is typical — depending on value chain complexity and stakeholder engagement scope. EcoActive’s structured workflow significantly reduces this timeline.

Does the DMA need board sign-off?

ESRS 1 requires governance over the DMA process. In practice, material topics should be reviewed and endorsed by senior governance — typically the audit committee or sustainability committee — before the sustainability statement is approved.

Does the DMA have to be repeated every year?

Yes, with proportionality. Companies must reassess each reporting period, but ESRS 1 allows a lighter-touch update if circumstances have not materially changed. Thresholds and methodology documentation must still be maintained.

What is the value chain scope for a CSRD DMA?

ESRS 1 requires assessment across the full value chain — upstream (suppliers, raw materials, contracted workers), own operations, and downstream (distributors, retailers, end-users, product end-of-life). Proportionality applies to depth of assessment across tiers.

What happens if our DMA is challenged during assurance?

Limited assurance under CSRD covers the process and documentation of the DMA, not just its conclusions. Gaps in stakeholder evidence or undocumented thresholds can result in a qualified opinion. EcoActive’s audit and review capabilities are designed to address this — with full documentation exports structured for assurance.
