Structured analysis: criteria → verdict → first reporting year
Double materiality assessment
Step-by-step DMA process with impact vs. financial materiality
Gap assessment
Table: ESRS Topic | Current State | Gap | Priority | Action
Replaces the Non-Financial Reporting Directive (NFRD) — expands scope from ~11,000 to ~50,000 companies
Objective
Ensure companies disclose consistent, comparable, and reliable sustainability information to support the EU Green Deal, sustainable finance objectives, and investor/stakeholder decision-making. Reporting must follow the double materiality principle.

Micro-enterprises are fully exempt.
Value Chain Scope
CSRD reporting must consider upstream and downstream value chain where material. Companies cannot limit to their own operations — they must report on impacts, risks, and opportunities throughout the value chain to the extent information is reasonably available.
Double Materiality Assessment (DMA)
The DMA is the cornerstone of CSRD compliance. Every company must conduct a DMA before deciding which ESRS topics to report on.
Two Perspectives
1. Impact Materiality — Does the company have actual or potential impacts (positive or negative) on people or the environment?
2. Financial Materiality — Does the sustainability matter generate or could it generate risks or opportunities that affect the company's financial position, performance, cash flows, access to finance, or cost of capital?
Consider: current effects AND anticipated effects over short/medium/long term
A topic is material if it meets either or both criteria. Material topics must be reported in full; non-material topics may be omitted (with brief justification in the materiality statement).
DMA Process (ESRS 1, paras. 45–56)
Understand the context — map business activities, relationships, and value chain
Identify actual and potential impacts — consult stakeholders (ESRS 1, para. 22)
Assess significance of impacts (scale, scope, irremediability, likelihood for potential)
Identify financial risks and opportunities from sustainability matters
Assess financial significance (magnitude, likelihood, time horizon)
Determine materiality — topic by topic, using both lenses
Document the DMA — disclose the process (ESRS 2 SBM-3)
Validate and update — at least annually

Reporting Format & Assurance
Location in Annual Report
CSRD disclosures must appear in a dedicated section of the management report (Accounting Directive, Art. 19a). Cannot be a standalone sustainability report.
Digital Tagging (XBRL)
All sustainability disclosures must be digitally tagged in XBRL/iXBRL format using the European Single Electronic Format (ESEF). Commission taxonomy pending for sustainability.
Third-Party Assurance (Art. 26a)
Limited assurance required initially (from first reporting year)
Reasonable assurance standard to be phased in later (Commission review by 2028)
Assurance by statutory auditor or independent assurance services provider (IASP)
Must cover: compliance with ESRS, DMA process, sustainability information
Value Chain Data Challenges
Where value chain data is unavailable, companies may use:
Proxy data / sector averages
Estimates based on reasonable assumptions
Must disclose data estimation approach and limitations
