ThemisIQ module

Materiality
Assessment

The impact half of a double materiality assessment, run by your own team: stakeholder engagement, all ten ESRS topics determined in both directions, and a record of who decided what. For companies reporting under CSRD — and for the suppliers their reporting puts questions to.

$4,900 USD per year — 365 days of platform access. No per-seat charges, no separate fee for the survey, no extra cost when you bring colleagues in to help. Add Climate Risk and the multi-module discount applies automatically.

A double materiality assessment is how a company works out which sustainability topics actually matter to it — looked at from two directions. Your impact on the world: where your operations and supply chain cause harm or do good. The world’s impact on you: where sustainability issues create financial risk or opportunity. A topic is material if it’s significant either way. Both halves together are what makes it double.

The ThemisIQ Materiality Assessment is the impact side of that, end to end. The financial side is ThemisIQ Climate Risk, and the two are designed to work together.

Which module do I need?

Double materiality has two halves, and ThemisIQ sells them separately because they are different exercises. This page is the impact half — how your organisation affects people and the environment. The financial half, how sustainability issues affect your organisation, is Climate Risk. Reporting under CSRD, you need both. Reporting under IFRS S2 alone, you need Climate Risk and not this.

The impact half · you are here
Materiality Assessment

How your organisation affects people and the environment. Stakeholder engagement, all ten ESRS topics determined by named people, a divergence register and a disclosure roadmap.

The financial half
Climate Risk

How sustainability issues affect your organisation. IFRS S2 single materiality, physical and transition risk, multi-scenario resilience, and a ten-topic screening.

Does this apply to you, and when?

If you’re in scope for CSRD, it’s mandatory and it comes first. CSRD is the EU law setting out who must publish a sustainability report and when; ESRS are the standards defining what goes in it. The law says you must report; the standards say how. Your materiality assessment determines which parts of those standards apply — so nothing else can be scoped until it’s done.

EU companies are in scope with more than 1,000 employees and more than €450 million in net turnover — both, not either. Companies already reporting continue; everyone else who remains in scope reports for financial year 2027, published in 2028. Listed SMEs have been removed from mandatory scope entirely.

Non-EU companies are caught on EU footprint rather than global size — broadly, more than €450 million of net turnover generated in the EU, plus an EU subsidiary or branch above a threshold of its own. Timing runs later and the rules are still being finalised.If you’re a US or UK group with EU operations, establish which entity holds the obligation before anyone starts work.

2028 isn’t far away. Your first report covers all of financial year 2027, so data collection starts in January 2027 — and the assessment comes first, because it determines what you collect. That makes 2026 the year it gets done.

And if you’re not in scope, the questions still come — just from customers, banks and investors rather than a regulator. In-scope companies must report on their value chain, so their suppliers get asked. One assessment, on your schedule, answers every version of that question you’ll get this year. The regulation sets the standard; the customers set the timeline.

Why ThemisIQ for your Materiality Assessment

This is serious work and it deserves to be done well — which usually means an expensive engagement, repeated each year. ThemisIQ makes the same methodology something your own team can run.

The reasoning is captured as you go.

What separates a strong assessment from a weak one isn’t effort — it’s whether you can show how you got there. Every judgement is attributed to the person who made it, with their role. Every threshold and rule is printed in the report. Where your conclusion differs from what stakeholders told you, the difference is recorded and explained, because that’s the first thing an assurer asks about.

Stakeholder engagement, handled.

You decide who to ask; ThemisIQ distributes the questionnaire, chases non-responders and analyses the results. It tells you when your invitation list has a gap — if no group you invited can speak to a topic, that shows with the reason stated rather than as silence you discover at assurance. Responses stay anonymous by a printed rule. Where stakeholders split sharply, it’s flagged rather than averaged away, and where your own workforce describes their conditions differently from workers in your supply chain, the two are shown side by side.

Ten topics, each assessed twice — once for harm, once for benefit.

ThemisIQ follows the ESRS topical standards published by the European Commission. ESRS Set 1 organises those topics into ten topical standards — E1–E5 environmental, S1–S4 social, and G1 governance. Commission Delegated Regulation (EU) 2023/2772.

The right people make the calls.

For each topic you decide whether your business is causing harm and whether it’s creating benefit, with the stakeholder results on the same screen. You don’t have to do it all yourself: assign workforce topics to HR and supply chain topics to procurement, each with a link to their part only. Their name and role appear in the report beside their judgement — which is what makes a determination defensible. You keep the final say, and any override is recorded with its reason.

You finish with something you can hand over.

A board report written for directors or senior leadership rather than specialists. Its contents, and the two things that come with it, are set out under What you get below.

Year two is an update, not a fresh engagement. The process and the reasoning stay in your platform.

What you get

The deliverable is the Materiality assessment report — a board paper written for directors or senior leadership rather than specialists. No sample is published. It prints twelve sections, in this order:

1Purpose and method
2Findings
3Stakeholder engagement
4Stakeholder responses
5Divided responses
6Own workforce and value chainthe two set beside each other
7Severity determinations
8Disclosure requirements
9Divergence register
10Method and standards applied
11Scope and limitations
12Implications

The last of those, Implications, is the section to read if you want to know what the exercise is worth when nobody is making you do it: where attention is, and where it is not; what the organisation cannot yet see; where the inside and the outside disagree; and what follows from a material topic.

Two more things come out of the same work:

A disclosure roadmap listing which requirements your conclusions have triggered, so you know the reporting workload before you start it.

A versioned record that freezes what you decided, under which version of the standards, and when.

If you already have Climate Risk

That module screens all ten topics on both axes, so you already have a first-pass view of where your impacts sit. What it can’t do is meet the ESRS requirement that your impact conclusions be informed by the people affected by them — its own report says so, on the cover.

This module is what closes that gap: real stakeholder engagement, determinations made by named people, and a record that holds up when someone asks how you got there.

Scope thresholds and reporting dates as at August 2026. Both CSRD scope and the ESRS standards were revised during 2026, and guidance for non-EU groups is still in development.If you’re close to a threshold, check your position rather than relying on a summary.

The ThemisIQ Materiality Assessment currently supports the revised ESRS standards, required for financial years beginning on or after 1 January 2027. The 2023 standards and transitional reliefs are on the roadmap.
