The Materiality Assessment
Knowing what matters for your organization.

Materiality determination is now a mandatory part of sustainability disclosure under both IFRS S2 and CSRD ESRS. ThemisIQ's Materiality Assessment delivers single materiality for IFRS S2 and double materiality for CSRD — through one engine, with the methodology your auditor expects.

Why now

Materiality determination is no longer optional.

Both major global frameworks now require entities to formally determine which sustainability topics are material — and to document the methodology behind that judgment. Auditors and assurance providers expect to see this work, not just its conclusions.

IFRS S2 / ISSB
Active globally

Effective FY2024+ in Canada (CSDS), the UK, Australia, New Zealand, Brazil, Japan and across 30+ ISSB-adopting jurisdictions. S2 requires identifying climate-related risks and opportunities that could reasonably be expected to affect enterprise value — a single (financial) materiality judgment.

CSRD / ESRS
Wave 2 · 2026

Large EU companies and EU-listed entities file their first ESRS reports starting in 2026 for FY2025 data; Wave 2 listed SMEs follow for FY2026. CSRD requires double materiality — the topics that affect the entity (financial) and those the entity affects (impact), across all ten ESRS topical standards.

Who needs this in your organization

Compliance, Legal, Finance, or Sustainability — whoever is holding the question.

Sustainability disclosure obligations are landing across functions. Many organizations don't yet have a dedicated sustainability lead — the responsibility falls to whoever is closest to the regulatory exposure. The Materiality Assessment is designed to be useful regardless of where you sit.

Compliance
Documented methodology, audit trail, and defensible scoping for regulatory submissions.
Legal
Framework alignment (IPCC AR6, TCFD, ESRS) — no licensed third-party classification reproduced. Clear limitations stated.
Finance
Financial materiality scoring across topics, with the scenario rationale required by S2 and ESRS.
Sustainability
Double materiality matrix, full ESRS topic coverage, methodology built on public frameworks.
What is materiality assessment?

Single materiality, double materiality — what's the difference?

Both frameworks ask you to identify which sustainability topics are material. They differ on what counts as material — and that distinction is what separates an S2 disclosure from a CSRD disclosure.

Single (financial) materiality
IFRS S2 / ISSB

The outside-in view: how do climate-related (and broader sustainability) risks affect the entity's enterprise value? One axis: financial impact.

Double materiality
CSRD / ESRS

Single materiality plus the inside-out view: how does the entity affect people and the environment? Two axes: financial and impact materiality, plotted as a matrix.

Each ESRS topic is plotted on both axes. Topics in the top-right are material on both — your highest reporting and management priority.

How it works

From inputs to defensible output — in less time than you think.

A guided wizard captures the entity's profile and produces a complete materiality determination, risk register, and methodology-rich report ready for review.

1
Profile
Entity, sector, IPCC AR6 regions of operation, asset profile, policy jurisdictions, reporting period.
2
Scenario
Sensible defaults pre-selected (SSP2-4.5, medium horizon) with rationale — change them if you have a reason to.
3
Impact (CSRD only)
Self-assessment across the ten ESRS topics, pre-filled from industry baseline — adjust to your reality.
4
Determine
Materiality determination, double materiality matrix, physical and transition risk register, and a downloadable CSRD- or S2-shaped report.

Two sample reports — same entity, two standards.

Both samples below were generated by the live ThemisIQ Materiality Assessment for a fictional industrial-manufacturing entity (Magnetic Industrial Components Ltd., FY2025) operating in Eastern North America and Northern Europe. Same entity, two standards — the difference is the standard, not the engine.

Why ThemisIQ

Built on public frameworks. Defensible by design.

The Materiality Assessment is grounded in independent, public methodology — no licensed third-party classification is reproduced. Every weighting and topic mapping is traceable to its source framework.

IPCC AR6 reference regions
The 20 land regions used for physical-risk geography are drawn from the IPCC Sixth Assessment Report Working Group I reference-region set.
TCFD risk categories
Transition risks follow the Task Force on Climate-related Financial Disclosures classification: policy, technology, market, and reputation.
ESRS topical standards
The impact-materiality axis assesses the ten ESRS topical standards (E1–E5 environmental, S1–S4 social, G1 governance).
IPCC SSP & NGFS scenarios
Both IPCC Shared Socioeconomic Pathways (SSP1-2.6, SSP2-4.5, SSP5-8.5) and NGFS scenarios (Orderly, Disorderly, Hot House) are available.
Intellectual honesty

The ThemisIQ Materiality Assessment is a structured screening intended to scope and support a formal IFRS S2 disclosure or CSRD double materiality assessment. A fully compliant ESRS assessment additionally requires a defined materiality threshold agreed by governance, stakeholder engagement informing the impact axis, and resilience testing across a range of scenarios. We tell you this on the cover of every report, not in fine print.
