What is CSRD?
The Corporate Sustainability Reporting Directive (CSRD) is the EU's mandatory ESG reporting regulation that requires companies to disclose standardized, audited sustainability information with financial relevance.
CSRD disclosures are increasingly used by investors and lenders to price risk, assess valuation, and make capital allocation decisions.
Mandatory ESG disclosure regulation in the EU
Expands scope significantly beyond previous rules
Requires standardized, detailed, and audited reporting
Links ESG directly to financial performance and risk
CSRD in 30 Seconds
CSRD is an EU regulation requiring companies to disclose ESG information
It replaces and expands the Non-Financial Reporting Directive (NFRD)
Applies to thousands of companies, including non-EU firms with EU exposure
Requires reporting under ESRS (European Sustainability Reporting Standards)
Introduces double materiality
Requires audit/assurance of ESG disclosures
CSRD transforms ESG from voluntary reporting into mandatory, structured disclosure
What CSRD Actually Does
CSRD requires companies to systematically integrate ESG into their reporting and decision-making processes.
Disclose ESG Information
Environmental - climate, emissions, resources
Social - workforce, supply chain
Governance - controls, risk, oversight
Use Standardized Framework (ESRS)
Common reporting structure
Comparable across companies
Integrate ESG with Financial Reporting
ESG disclosures linked to financial risks and impacts
Undergo Audit / Assurance
ESG data must be verified
Build Data Infrastructure
ERP upgrades
ESG data platforms
Internal controls
CSRD shifts ESG from narrative disclosure to data-driven reporting
CSRD requires companies to build data infrastructure comparable to financial reporting systems
CSRD turns ESG into structured, auditable, decision-useful data
Who CSRD Applies To
CSRD has broad scope, affecting both EU and non-EU companies through extraterritorial application.
EU Companies
Large companies meeting thresholds:
€40M+ turnover
€20M+ assets
250+ employees
Listed Companies
Including SMEs (with phased timelines)
Non-EU Companies (VERY IMPORTANT)
Companies with:
€150M+ EU revenue
EU subsidiaries or branches
CSRD has extraterritorial impact, affecting global companies operating in the EU
Many companies are indirectly affected through supply chain reporting requirements
Omnibus I Directive Update
The Omnibus I Directive, approved by the European Parliament on 16 December 2025, signed on 24 February 2026, and effective from 19 March 2026, significantly revised CSRD thresholds for non-EU companies while maintaining the core framework and double-materiality requirement.
Updated Non-EU Thresholds
Omnibus I raised the thresholds for non-EU companies, reducing the number of captured non-EU groups:
Net EU Turnover
Increased from €150M to €450M
EU Subsidiary/Branch Turnover
Increased from €40M to €200M
Third-Country Undertakings (Non-EU Companies)
A non-EU company must report under CSRD if it meets both conditions:
- • Net EU turnover exceeding €450 million for the last two consecutive financial years
- • At least one EU subsidiary or EU branch with net turnover exceeding €200 million
Additionally, listed non-EU companies with more than 1,000 employees and global turnover above €450 million are in scope regardless of subsidiary/branch thresholds.
Other Omnibus I Changes
Beyond threshold updates, Omnibus I introduced other simplifications:
- • Simplified ESRS data-point set (reducing mandatory data points by ~61%)
- • Extended SME opt-out provisions
- • Maintained core double-materiality requirement
- • Estimated €4.7 billion (~44%) compliance cost savings for EU companies
Non-EU Timeline
Data collection commences for financial year 2028, with the first sustainability report due in 2029. This timeline applies to Gulf-based conglomerates, US corporations, and Asian manufacturers with material European revenue.
Verify Your EU Revenue Against New Thresholds
The Omnibus I amendment significantly raised non-EU thresholds. Verify your current EU revenue against the new figures (€450M net EU turnover, €200M subsidiary/branch) before assuming you are or are not in scope.
ESRS Standards
The 12 European Sustainability Reporting Standards (ESRS) define every disclosure requirement under CSRD. They are divided into cross-cutting standards and topic-specific standards across environmental, social, and governance dimensions.
The 12 ESRS Standards
ESRS 1 - Cross-cutting: General Requirements
General principles for sustainability reporting
ESRS 2 - Cross-cutting: General Disclosures
Mandatory for all reporters, no materiality escape
ESRS E1 - Environment: Climate Change
GHG emissions, climate risks, transition plans
ESRS E2 - Environment: Pollution
Air, water, soil pollution, waste management
ESRS E3 - Environment: Water & Marine Resources
Water consumption, water stress, marine impacts
ESRS E4 - Environment: Biodiversity & Ecosystems
Biodiversity loss, ecosystem services, land use
ESRS E5 - Environment: Resource Use & Circular Economy
Material flows, circular economy, resource efficiency
ESRS S1 - Social: Own Workforce
Employment conditions, health & safety, training
ESRS S2 - Social: Workers in Value Chain
Supply chain labor conditions, human rights
ESRS S3 - Social: Affected Communities
Community impacts, stakeholder engagement
ESRS S4 - Social: Consumers & End Users
Consumer safety, privacy, product responsibility
ESRS G1 - Governance: Business Conduct
Anti-corruption, lobbying, political influence
Simplified ESRS (Draft)
A draft simplified ESRS was released on 3 December 2025 to reduce compliance burden:
Length Reduction
~50% shorter total length
Data Point Reduction
~61% fewer mandatory data points
Cost Savings
€4.7 billion (~44%) saved
Estimated savings: ~€1.1 million per large company and ~€150,000 per smaller firm in scope. Final adoption of the simplified ESRS is expected before mid-2026.
Materiality Application
ESRS 2 (General Disclosures) is mandatory for all reporters—no materiality escape. The topic-specific standards (E1–E5, S1–S4, G1) are subject to materiality; companies only disclose on topics that pass the double materiality assessment. Even with simplification, start with ESRS 2 and E1 as universal baselines.
ESRS Provides the Standardized Framework
ESRS ensures consistent, comparable disclosures across companies while the simplified version reduces compliance burden without compromising the core double-materiality framework.
What Companies Must Report
CSRD requires comprehensive, granular disclosures across environmental, social, and governance dimensions.
Environmental
Emissions (Scope 1, 2, 3)
Climate risk
Resource use
Social
Workforce conditions
Human rights
Supply chain impacts
Governance
Board oversight
Risk management
Internal controls
CSRD requires granular, quantitative, and forward-looking disclosures
Disclosures include both historical data and forward-looking targets and scenarios
Double Materiality (Core Concept)
Double materiality is the conceptual and procedural centerpiece of CSRD. It requires companies to apply two simultaneous lenses to every potential sustainability topic. A topic is material under CSRD if it is material from either perspective—not both.
Impact Materiality
How do our activities affect people and the planet—both positively and negatively, directly and through our value chain?
- • Actual and potential negative impacts
- • Positive contributions to society and environment
- • Scope includes own operations, upstream and downstream value chain
Financial Materiality
How do sustainability matters affect our financial performance, position, and cash flows—including risks and opportunities?
- • Physical climate risks (acute and chronic)
- • Transition risks from regulatory and market shifts
- • Opportunities: efficiency gains, new markets, resilience
Assessment Requirements
The assessment process must be documented, subject to senior governance oversight, and auditable for assurance purposes. ESRS 1 requires that the double materiality assessment process be disclosed in the sustainability statement itself—including who was involved, how topics were identified, how they were scored, and how senior management reviewed and approved the outcome.
Companies must assess and report on both dimensions simultaneously
Double materiality expands ESG from risk analysis to full impact + financial integration
Key Requirement: Process Disclosure
ESRS 1 requires disclosure of the double materiality assessment process itself—methodology, governance, and decision-making. This transparency is essential for assurance and stakeholder trust.
Timeline & Implementation
CSRD implementation is phased, with expanding scope over time. The Omnibus I Directive (effective 19 March 2026) updated thresholds for non-EU companies while maintaining the phased implementation schedule.
2024 - Wave 1 Begins
Large EU listed companies (previously under NFRD) file first CSRD-compliant reports for FY2024. Reports due in 2025 with limited assurance.
2025 - Wave 2 Begins
Large EU non-listed companies above size thresholds must comply. EU subsidiaries of non-EU groups may be captured here if they independently meet large-undertaking thresholds (balance sheet >€25M, net turnover >€50M, >250 employees—any two of three).
2026 - Wave 3 Begins
EU-listed SMEs (with opt-in and proportionate requirements) must comply. Reports due in 2027.
19 March 2026 - Omnibus I Effective
Omnibus I Directive (approved 16 Dec 2025, signed 24 Feb 2026) enters into force. New thresholds—€450M net EU turnover / €200M subsidiary branch—apply from this date for non-EU companies.
2028 - Non-EU Data Collection Starts
Third-country undertakings (net EU turnover >€450M + EU presence >€200M) and listed non-EU firms (>1,000 employees + >€450M global turnover) commence FY 2028 data collection.
2029 - First Non-EU Reports Due
First CSRD-compliant sustainability statement filed, with limited assurance. EU Commission may later mandate upgrade to reasonable assurance.
Non-EU Companies Have Until 2028 to Prepare
With the non-EU deadline set at FY 2028 data (report due 2029), organizations have a window to prepare systematically rather than reactively. Use this time to build data infrastructure and conduct materiality assessments.
6-Step Preparation Plan
Preparation for CSRD is a 12–24 month programme for most large enterprises. With the non-EU deadline set at FY 2028 data (report due 2029), organizations have a window to prepare systematically rather than reactively.
Scope Confirmation and Gap Analysis
Weeks 1–3. Confirm whether and when your entity falls within CSRD scope. Map your current ESG data against ESRS 2 and your highest-likelihood material topics to identify the most significant data gaps.
Double Materiality Assessment
Weeks 4–10. Conduct a structured DMA across all ESRS topics, engaging senior stakeholders in impact and financial materiality scoring. Document the process and governance trail for assurance.
ESRS Data Point Mapping
Weeks 8–14. For each material topic, map every required ESRS data point to existing data sources, identify gaps, and assign ownership. Prioritise quantitative KPIs that require system integration.
Data Governance and Controls
Weeks 12–20. Establish data collection workflows, approval hierarchies, and audit trails. Define calculation methodologies, set emission factors, and document control frameworks for assurance-readiness.
Draft Sustainability Statement
Weeks 18–26. Prepare the full sustainability statement against ESRS requirements, including narrative sections, quantitative tables, and entity-specific disclosures. Complete iXBRL tagging for digital submission.
Assurance and Filing
Weeks 24–30. Engage your assurance provider early—ideally from Step 4. Conduct a pre-assurance readiness review, address findings, and submit the assured sustainability statement with the annual report.
Start Early, Engage Assurance Providers Early
CSRD preparation is a 12-24 month programme. Engage your assurance provider from Step 4 (Data Governance) to ensure your controls and documentation meet assurance requirements from the start.
Key Financial Mechanisms
CSRD affects companies through specific, measurable financial mechanisms.
1. Compliance Cost Mechanism
Data collection, reporting systems, audit costs
→ Increased operating costs
2. Risk Transparency Mechanism
Disclosure of climate and ESG risks
→ Impacts investor perception
3. Capital Market Mechanism
Investors use disclosures
→ Impacts valuation and cost of capital
4. Market Access Mechanism
ESG compliance required for EU operations
→ Affects revenue access
Financial Outputs:
• Operating cost increase - compliance and systems
• Risk repricing - disclosed exposures
• Cost of capital / access - investor decisions
• Revenue / access impact - market differentiation
Real Financial Pathways
CSRD affects financial outcomes through concrete cause-effect chains.
Compliance Cost Pathway
CSRD Requirements → Data + Reporting Costs → Higher Operating Costs → Margin Impact
Transparency Pathway
ESG Disclosure → Increased Investor Visibility → Risk Pricing → Valuation Impact
Capital Access Pathway
Strong ESG Reporting → Investor Confidence → Lower Cost of Capital
Market Access Pathway
Non-Compliance → Regulatory Risk → Restricted EU Operations → Revenue Impact
Risk Exposure Pathway
Disclosed ESG Risks → Higher Perceived Risk → Spread Widening → Financing Impact
Competitive Disadvantage Pathway
Weak ESG Disclosure → Lower Transparency → Reduced Investor Confidence → Higher Cost of Capital → Competitive Disadvantage
Impact on Business & Strategy
CSRD fundamentally changes how companies operate and make strategic decisions.
Operational Impact
Data systems and reporting processes
Strategic Impact
ESG integrated into decision-making
Governance Impact
Board oversight required
CSRD forces ESG into core business strategy and operations
CSRD shifts ESG from a compliance function to a cross-functional operational requirement
Link to Financial Impact
CSRD is a key driver of financial impact through regulation.
Costs → compliance + systems
Revenue → market access
Risk → disclosure-driven pricing
Capital → investor decisions
CSRD is one of the primary mechanisms through which ESG becomes financially material
