Lucy Godshall, CSRD Advisory Leader at Ernst & Young LLP, explained that the 12 ESRS detail and organize the specific disclosure requirements for reporting under the CSRD. These disclosure requirements are complex and encompass more than 1,000 different data points. The ESRS include two cross-cutting standards and 10 topical standards on a range of environmental, sustainability and governance (ESG) topics, from biodiversity to climate change. The 10 standards contain 37 subtopics, many of which are further broken down into sub-subtopics, include the detailed disclosure requirements.
The ESRS require all companies within the scope of the CSRD to report on sustainability matters based on a double materiality principle. The DMA, to be completed for each reporting period, covers two dimensions:
- Financial materiality: What financial effects are triggered by these sustainability topics?
- Impact materiality: How do the company’s activities impact society and the environment?
A sustainability matter is material when it meets the criteria defined for impact materiality or financial materiality or both. These two aspects of materiality can be significantly interrelated. For example, a topic that is material today from an impact perspective could evolve and become financially material tomorrow.
Godshall recommended a three-step approach to determining materiality under the ESRS:
- Understand the business context: Know the activities and business relationships as well as the affected stakeholders. Also, consider any additional context, such as sector- or entity-specific topics.
- Identify the impacts, risks and opportunities (IROs): Consider the entire value chain, which is defined as the full spectrum of activities, resources and relationships from conception to the end of life of a product or service to identify IROs relevant to the company.
- Assess and determine the materiality of sustainability matters: Define materiality thresholds and detailed scoring criteria prescribed under the ESRS upon which to assess the IROs. Consolidate the results, document the process and report the outcomes.
The ESRS also emphasize both direct and indirect relationships, extending beyond first-tier suppliers to the country of origin and the broader value chain. Companies should consider two primary stakeholder groups: affected stakeholders and users of sustainability information. Affected stakeholders include employees, customers and vendors. Users of sustainability information include investors, creditors, business partners, governance bodies and analysts. Non-human entities, such as the environment, are considered a silent stakeholder. Companies should consider entities along the value chain and both sets of stakeholders in evaluating double materiality.
The ESRS provide guidance but also allow flexibility for defining materiality thresholds and developing scoring criteria. In doing this, the European Financial Reporting Advisory Group (EFRAG) guides companies to leverage existing internal processes, for example, to evaluate financial materiality or to identify risks and opportunities through a company’s enterprise risk management framework.
Amanda Kraus, CSRD Assurance Leader at Ernst & Young LLP, outlined the process for identifying and reporting material sustainability information under ESRS 1 and ESRS 2, which are known as the two topic-agnostic, cross-cutting standards. ESRS 1 describes the architecture of the ESRS and explains the drafting conventions, along with the fundamental concepts and requirements for preparing and presenting the sustainability information. It also outlines the double materiality principles. ESRS 2 describes the cross-cutting disclosure requirements that apply to all undertakings, regardless of sector and across the sustainability topics.
After completing the DMA, companies need to identify the disclosure requirements for reporting. Organizations should conduct an analysis to determine whether gaps exist in their current data and reporting processes against the disclosure requirements. The ESRS have minimum disclosure requirements (MDR) across four areas: policies, actions, targets and metrics. This structured approach helps companies create a roadmap to readiness for ESRS reporting.
Kraus also addressed assurance. The CSRD requires independent third-party assurance for sustainability statements, starting with the inaugural reporting year. Assurance encompasses three key areas:
- The DMA process
- The interaction of IROs with the entity’s strategy and business model
- The data points and disclosure requirements within the sustainability statement
Though the European Commission is expected to adopt a new assurance standard by October 2026, companies will want to prepare for assurance well in advance. Careful documentation in the inaugural year will help build repeatability into the process for future years.
