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.
Self-guided, or with advisors at the ready.
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 the free ThemisIQ Climate Risk Screening, and the two are designed to work together.
Which module do I need?
Double materiality has two halves, and ThemisIQ offers 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 the Climate Risk Screening, which is free. Reporting under CSRD, you need both. Reporting under IFRS S2 alone, you need the Climate Risk Screening and not this.
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.
How climate change could affect your organisation. Physical and transition risk across four climate scenarios, with a resilience report. Free with a company account.
Climate Risk 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.
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.
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:
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 have run the Climate Risk Screening
It covers the financial half: how physical and transition climate risks could affect your business across four scenarios. It does not assess your impacts on people and the environment, and ESRS asks that your impact conclusions be informed by the people affected by them.
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.
