CSRD Double Materiality in 2026, Why Assessments Take 6 Months and the 6 Week Workflow That Fixes It
A practical way for mid market ESG teams to map impact and financial materiality without duplicating effort across ESRS, GRI and ISSB

CSRD Double Materiality in 2026, Why Assessments Take 6 Months and the 6 Week Workflow That Fixes It
Most double materiality assessments at mid market companies do not fail because teams misunderstand CSRD.
They fail because the process becomes the work.
Six months in, there are dozens of interviews, competing topic lists, and no agreed IRO register. The assessment has expanded into a stakeholder engagement exercise, rather than producing a clear, defensible output.
For ESG Managers already balancing reporting, audits and internal requests, this creates a familiar problem. The same topics are analysed multiple times across ESRS, GRI and internal risk processes, with no shared structure.
This is avoidable.
The root problem, double materiality is treated as engagement, not as a data workflow
Guidance from EFRAG IG 1 (2024) and GRI 3 Material Topics is clear that impact materiality and financial materiality require both evidence and judgement.
Yet in practice, many teams default to:
Long stakeholder interview cycles
Manual topic long lists
Separate scoring exercises for each framework
Late stage alignment with risk and finance
This creates three structural issues:
Duplication across frameworks
The same ESG topics are assessed separately for ESRS materiality assessment, GRI disclosures and investor requests.No shared evidence layer
Scores are based on fragmented inputs, making them hard to defend or revisit.Delayed decision making
Judgement calls happen late, when the dataset is already inconsistent.
The result is predictable. Timelines stretch, confidence drops, and outputs stall.
A real pattern seen in mid market teams
A UK headquartered B2B software company with around 900 staff started a CSRD double materiality project in late 2025.
Six months later:
40 plus stakeholder interviews completed
Two competing shortlists of material topics
No agreed IRO register
The materiality assessment had become the project itself, rather than a structured output.
The DMA Parallelisation Framework
To fix this, Ella applies a named approach:
The DMA Parallelisation Framework
Instead of running steps sequentially, the workflow separates what can be automated from what must remain human judgement.
The framework has three layers
Evidence layer
All available data is collected and structured upfrontScoring layer
Initial impact and financial materiality scoring is run in parallelJudgement layer
ESG leads review, adjust thresholds and make final calls
This aligns with how ESRS, GRI and ISSB frameworks expect materiality to be evidenced, without repeating work.
The 6 week double materiality workflow
This is not a claim of guaranteed timelines. It is what becomes possible when the workflow is structured correctly.
Week 1 to 2, Build the topic and evidence base
Generate a company specific ESRS topic long list
Pull from policies, prior reports, risk registers and peer disclosures
Map topics to ESRS, GRI and ISSB once, not multiple times
This creates a single source of truth for impact materiality and financial materiality.
Week 2 to 3, Run first pass scoring in parallel
Apply structured scoring across all topics
Use sector data, peer disclosures and company inputs
Surface the evidence behind each score
At this stage, no stakeholder input is required yet.
Week 3 to 4, Targeted stakeholder engagement
Generate structured surveys and interview guides by persona
Focus only on topics where input changes outcomes
Ingest responses into a comparable scoring matrix
This reduces interview volume and increases consistency.
Week 4 to 5, Draft IRO register and matrix
Produce an initial impact, risk, opportunity register
Map directly to ESRS topic structure
Build a working materiality matrix
This turns inputs into outputs early.
Week 5 to 6, Human judgement and sign off
Flag thresholds and borderline topics
ESG lead reviews and adjusts
Final materiality decisions are documented and justified
The key point is simple. Human judgement is preserved, but applied where it matters.
Where this approach works, and where it does not
Works well when
The company already has fragmented ESG data
Multiple frameworks are in scope, ESRS, GRI, ISSB
The ESG lead needs defensible outputs quickly
There is pressure from investors or PE stakeholders
Less effective when
No internal documentation exists at all
Leadership alignment on ESG is missing
The goal is purely exploratory rather than compliance driven
In these cases, stakeholder engagement still plays a larger role.
How Ella runs the workflow in practice
Ella, an AI ESG agent, focuses on the evidence and scoring layers so that teams do not repeat work.
Typical workflow:
Pulls a company specific ESRS topic long list from documents, policies, risk registers, peer benchmarks and customer questionnaires
Runs first pass scoring across impact and financial materiality, with visible evidence behind each score
Generates stakeholder engagement packs and ingests responses into a structured matrix
Produces a draft IRO register mapped to ESRS topics
Flags judgement calls for ESG leads, rather than hiding them
This is where Ella differs from tools like Datamaran, which are strong on external signal tracking. Ella runs the end to end double materiality workflow, including internal evidence and output generation.
A contrarian point, more interviews do not improve materiality quality
There is a common assumption that more stakeholder interviews lead to better outcomes.
In practice, this often creates:
Conflicting inputs that are hard to reconcile
Bias towards louder stakeholders
Delays in decision making
Guidance from EFRAG (2024) emphasises evidence and documentation, not volume of engagement.
Fewer, better targeted inputs, combined with structured scoring, produce more defensible results.
How to avoid doing the work twice across CSRD, GRI and ISSB
The key is not to map frameworks at the end.
Instead:
Build a single topic list aligned to ESRS
Map GRI and ISSB at the same time
Use one scoring model across all frameworks
Store evidence once, reuse everywhere
This removes duplication and ensures consistency across disclosures.
For teams managing multiple reporting obligations, this is the difference between repeat work and scalable process.

For ESG teams facing a six month timeline, the key question is not whether double materiality is required.
It is how to structure it so the work is done once.
