CSRD ESG Reporting Sustainability ESRS Corporate Reporting

Introduction

The Corporate Sustainability Reporting Directive (CSRD) represents the most significant expansion of sustainability reporting requirements globally. This article provides a comprehensive implementation guide for companies subject to CSRD.

CSRD Overview

Scope and Applicability

  • Phase 1 (2024 reports for 2025): Large public-interest entities (listed companies) with >500 employees
  • Phase 2 (2026 reports for 2027): Large companies meeting 2 of 3 criteria (>250 employees, €40M turnover, €20M assets)
  • Phase 3 (2027 reports for 2028): Listed SMEs (except micro-enterprises)
  • Phase 4 (2029 reports for 2030): Non-EU companies with >€150M EU revenue

Key Features

  • Mandatory sustainability reporting in management report
  • Audit/assurance required (limited assurance initially, reasonable by 2028)
  • Digital reporting (XBRL tagging) for EU Single Access Point (ESAP)
  • Double materiality assessment (impact materiality + financial materiality)

European Sustainability Reporting Standards (ESRS)

Cross-Cutting Standards

  • ESRS 1: General requirements (materiality assessment, reporting boundaries, qualitative characteristics)
  • ESRS 2: General disclosures (governance, strategy, risk management, metrics and targets)

Environmental Standards

  • ESRS E1: Climate change (transition plans, GHG emissions, energy, climate risks)
  • ESRS E2: Pollution (air, water, soil, substances of concern)
  • ESRS E3: Water and marine resources (water consumption, withdrawals, discharges)
  • ESRS E4: Biodiversity and ecosystems (impacts on biodiversity, restoration, compensation)
  • ESRS E5: Resource use and circular economy (resource inflows/outflows, waste, circular design)

Social Standards

  • ESRS S1: Own workforce (working conditions, equal treatment, collective bargaining, health and safety)
  • ESRS S2: Workers in value chain (due diligence, working conditions)
  • ESRS S3: Affected communities (community impacts, land rights, indigenous rights)
  • ESRS S4: Consumers and end-users (product safety, responsible marketing, privacy)

Governance Standards

  • ESRS G1: Business conduct (corporate culture, risk management, anti-corruption, political engagement, supplier relationships)

Implementation Timeline

2024-2025 (Phase 1)

  • Large public-interest entities (500+ employees) report for FY2024
  • First reports due in spring 2025
  • Limited assurance required

2025-2026 (Preparation for Phase 2)

  • Large companies prepare for 2026 reporting
  • Develop data collection systems
  • Conduct double materiality assessment
  • Engage assurance providers

2026-2027 (Phase 2 Reporting)

  • Large companies report for FY2026 (reports due 2027)
  • Listed SMEs prepare for Phase 3

Double Materiality Assessment

Impact Materiality

  • Company's actual or potential impacts on environment and people
  • Short-, medium-, long-term impacts (actual or potential)
  • Severity (scale, scope, irremediable character) and likelihood
  • Consider entire value chain (upstream and downstream)

Financial Materiality

  • Sustainability matters that affect company's financial performance
  • Risks and opportunities affecting enterprise value
  • Same thresholds as traditional financial materiality
  • Integration with financial risk management

Materiality Determination

  • Engage stakeholders (investors, customers, employees, affected communities)
  • Document assessment methodology and outcomes
  • Material topics disclosed; non-material topics not required

Data Collection and Systems

Key Data Requirements

  • GHG emissions: Scope 1, Scope 2, Scope 3 (value chain)
  • Energy consumption and intensity
  • Workforce data: headcount, turnover, diversity, training
  • Health and safety: injury rates, fatalities
  • Water consumption, waste generation

Systems Considerations

  • Extend existing ERP systems to capture ESG data
  • Implement ESG reporting software
  • Establish internal controls over ESG data
  • Document data sources, assumptions, methodologies

Assurance and Audit

Limited Assurance (Initial Phase)

  • Procedures: inquiry, analytical procedures, limited verification
  • Auditor provides negative assurance (nothing has come to attention indicating non-compliance)
  • Less detailed testing than reasonable assurance

Reasonable Assurance (Future Phase)

  • Detailed testing, controls testing, verification of underlying data
  • Positive assurance (auditor opinion that reporting is fairly stated)
  • Similar to financial statement audit

Auditor Selection

  • Statutory auditor may provide assurance (may require separate engagement)
  • Specialized sustainability assurance providers
  • Independence requirements apply

Value Chain Reporting

Scope 3 Emissions

  • Categories: purchased goods, capital goods, fuel and energy, upstream transportation, waste, business travel, employee commuting, upstream leased assets, downstream transportation, processing of sold products, use of sold products, end-of-life treatment, downstream leased assets, franchises, investments
  • Estimates acceptable where data unavailable
  • Phase-in for smaller companies

Value Chain Due Diligence

  • Identify adverse impacts in value chain
  • Supplier engagement and remediation
  • Reporting on due diligence processes

Practical Implementation Steps

  1. Establish ESG governance: board and management oversight
  2. Conduct double materiality assessment
  3. Map ESRS requirements to existing disclosures
  4. Identify data gaps and develop collection systems
  5. Implement internal controls and documentation
  6. Engage assurance provider (early engagement for 2025-2026)
  7. Prepare for digital reporting (XBRL)
  8. Monitor evolving guidance (EFRAG, ESMA, EC)

Common Implementation Challenges

  • Data availability: Scope 3 emissions, value chain data
  • System integration: ESG data across multiple systems
  • Stakeholder engagement: Identifying affected stakeholders
  • Double materiality: Determining material topics
  • Assurance readiness: Preparing for audit
