Navigating CSRD: A Practical Handbook

What is CSRD and why does it matter?

The Corporate Sustainability Reporting Directive (CSRD) is an EU regulation that replaced the Non-Financial Reporting Directive (NFRD) from 2024 onwards. It is the most significant expansion of corporate sustainability disclosure requirements in history — moving from a roughly 400-word narrative in an annual report to a structured, digitally tagged, auditable sustainability statement of potentially hundreds of pages.

Who is in scope — and when?

The European Sustainability Reporting Standards (ESRS)

CSRD requires reporting against the European Sustainability Reporting Standards (ESRS), developed by EFRAG. There are two cross-cutting standards and ten topical standards across environment, social, and governance.

Cross-cutting standards

• ESRS 1 — General Requirements: The overarching principles, reporting boundary, value chain coverage, and data quality requirements
• ESRS 2 — General Disclosures: Governance, strategy, business model, double materiality process, stakeholder engagement

Environmental standards (ESRS E1–E5)

• ESRS E1 — Climate Change: GHG emissions (Scopes 1, 2, 3), transition plans, physical and transition risk exposure
• ESRS E2 — Pollution: Air, water, soil pollution, substances of concern, microplastics
• ESRS E3 — Water and Marine Resources: Water consumption, water intensity, impact on marine ecosystems
• ESRS E4 — Biodiversity and Ecosystems: Impact on species, habitats, land use, ecosystem services
• ESRS E5 — Resource Use and Circular Economy: Material inputs, waste, product end-of-life, circular design

Social standards (ESRS S1–S4)

• ESRS S1 — Own Workforce: Working conditions, living wages, health & safety, diversity, non-discrimination
• ESRS S2 — Workers in the Value Chain: Supplier labour standards, human rights due diligence, ILO conventions
• ESRS S3 — Affected Communities: Community engagement, indigenous peoples' rights, access to resources
• ESRS S4 — Consumers and End-Users: Data privacy, product safety, responsible marketing, consumer access

Governance standard (ESRS G1)

• ESRS G1 — Business Conduct: Anti-corruption and anti-bribery, lobbying, whistleblower protection, supplier payment practices

Double materiality — the defining concept

The most important conceptual shift in CSRD is the requirement for double materiality assessment. Unlike traditional financial materiality (which asks: 'does this affect the company's finances?'), double materiality has two lenses:

• Financial materiality (Outside-In): How do sustainability issues affect the company's financial performance, position, and cash flows?
• Impact materiality (Inside-Out): How does the company's operations and value chain affect people and the environment?

A topic is material under CSRD if it is material from EITHER perspective. This means companies may need to disclose significant impacts they are causing even if those impacts do not affect their own financial results — a fundamental departure from traditional investor-centric disclosure philosophy.

What is new compared to NFRD?

Practical steps to prepare

1. 1Conduct a double materiality assessment: Identify all potentially material ESG topics using stakeholder engagement, peer analysis, and value chain mapping. This is the foundation — every disclosure decision flows from it.
2. 2Map your current data architecture: Inventory what ESG data you already collect, in what systems, with what quality. Most companies have significant data in HR, procurement, facilities, and EHS systems that needs to be unlocked.
3. 3Identify data gaps: Compare your current data against the ESRS disclosure requirements for your material topics. Prioritise Scope 3 emissions, social supply chain, and biodiversity — these are typically the largest gaps.
4. 4Assess your assurance readiness: Choose a third-party assurance provider early. Limited assurance requires the same documentation discipline as financial audit. Starting this conversation 18 months before your first report date is not too early.
5. 5Build governance structures: ESRS G1 and ESRS 2 require demonstrating board-level oversight of sustainability. Sustainability committees, board training, and executive ESG accountability frameworks need to be in place — not just documented.
6. 6Draft your first materiality statement: Publish a condensed version of your materiality assessment even before your first full CSRD report. This signals readiness to investors and the supply chain.
