European Sustainability Reporting Standards - ESRS

Understanding ESRS

The term ESRS refers to the European Sustainability Reporting Standards, a set of detailed reporting standards created to guide how companies disclose their sustainability information. Developed under the Corporate Sustainability Reporting Directive (CSRD), ESRS introduce a new era of structured, comparable, and decision-useful sustainability reporting across Europe.

These european standards aim to improve the quality, consistency, and relevance of data disclosed by companies, enabling investors, regulators, and civil society to better understand a company’s sustainability impact and its exposure to risks and opportunities.

Why ESRS Matter for Companies and Stakeholders

ESRS represent one of the most significant changes in corporate reporting in recent decades. Their objective is to align financial and non-financial information, ensuring that sustainability reporting becomes as robust and reliable as financial reporting.

For companies subject to the CSRD, ESRS provide a clear structure that helps ensure compliance with mandatory requirements, enhancing transparency and comparability throughout the EU. Furthermore, the european sustainability focus of ESRS improves stakeholder confidence by offering data that can be trusted and understood across sectors.

The Purpose and Scope of ESRS

The scope of ESRS is intentionally broad. These standards apply to large companies, listed SMEs, and eventually a wider group depending on EU regulatory expansion. The overarching goal is to create high-quality sustainability reporting that reflects how a company manages its risks, opportunities, and impacts on people and the environment.

The ESRS form a comprehensive framework covering environmental, social, and governance (governance) topics. They ensure that all relevant information is presented in a structured format that decision-makers can understand and use.

How ESRS Fit Within the European Regulatory Landscape

The ESRS were developed under the mandate of the European Commission following the adoption of the corporate sustainability reporting directive. Their development involved input from advisory bodies such as the reporting advisory group, sustainability experts, and accounting specialists.

These standards represent the european sustainability reporting backbone, helping the EU achieve its broader policy goals, including climate neutrality and respect for human rights throughout the value chain. ESRS also strengthen interoperability with international frameworks, ensuring European companies remain aligned with global expectations.

The Structure of ESRS: General and Topical Standards

ESRS consist of general requirements and topical standards. The general requirements explain how companies should apply the framework, define reporting principles, and set out how materiality assessment must be conducted.

Topical standards cover specific sustainability topics, such as environmental matters, social issues, and governance disclosures. Together, they create a robust sustainability reporting architecture that helps companies produce complete and reliable disclosures.

Double Materiality: A Core ESRS Principle

One of the most distinctive features of ESRS is double materiality. This concept combines two perspectives: a company’s impact on the world (impact materiality) and the financial consequences of sustainability factors on the company (financial materiality).

Conducting a strong materiality assessment is essential. It determines what the company must include in its ESRS report and ensures that the disclosed information reflects both internal and external priorities.

Conducting a Materiality Assessment Under ESRS

A robust assessment requires identifying all relevant environmental, social, and governance topics that affect the company or are affected by it. The process involves stakeholder engagement, analysis of risks and opportunities, and evaluation of impacts across the value chain.

This assessment guides the selection of sustainability reporting standards applicable to the business. The final ESRS reporting will therefore be tailored to the organisation’s unique risks, opportunities, and obligations.

ESRS and Interoperability With International Standards

To limit the reporting burden on multinational companies, ESRS are designed for high interoperability with international sustainability frameworks, including ISSB’s international sustainability standards, the Global Reporting Initiative (GRI), and other global norms.

This alignment ensures that companies reporting under ESRS can more easily address international expectations, reducing duplication and ensuring more efficient disclosure practices.

ESRS Environmental Topics and Climate Change

Environmental ESRS require clear and structured disclosures about climate-related information, including transition plans, climate change mitigation measures, and the impact of business activities on the environment.

Through ESRS, companies must explain how they address environmental risks and opportunities, ensure compliance with requirements, and manage emissions across their value chain.

ESRS Social Topics: Rights, Equity and Workforce Conditions

Social ESRS cover topics such as human rights, workforce conditions, diversity, and broader social impacts. Companies must disclose how they manage their impact on employees, communities, and business partners.

These social standards reinforce accountability and ensure that sustainability reporting includes elements beyond environmental or climate matters, providing a holistic picture of corporate behaviour.

ESRS Governance Topics and Disclosure Requirements

Governance ESRS cover structure, processes, and internal policy frameworks. They include expectations about the role of the board, internal control systems, and how oversight responsibilities are carried out.

This framework helps companies demonstrate how sustainability considerations are integrated into corporate strategy, decision-making, and long-term planning.

CSRD and ESRS: How They Work Together

The CSRD is the legislative foundation that mandates compliance with ESRS. It defines which companies must follow the requirements, the time of application, and the scope of sustainability reporting directive obligations.

The ESRS provide the detailed rules, while the CSRD ensures legal compliance, enforcement, and alignment with broader european goals.

Who Must Apply ESRS?

ESRS apply to large companies, listed SMEs, and certain financial institutions, as well as financial services organisations operating in Europe. Entities will be phased into the framework according to their size and characteristics.

Understanding whether your entity falls under the requirements is essential to plan systems, processes, and internal controls for compliant reporting.

ESRS Reporting: What Companies Must Prepare

Preparing an ESRS-aligned report requires gathering structured data, performing the double materiality test, and mapping disclosures across all relevant ESRS standards.

A compliant ESRS reporting cycle requires cross-department collaboration, reliable systems for capturing information, and clear documentation to ensure auditability under european financial reporting expectations.

ESRS and the Need for Reliable Sustainability Information

One of the main purposes of ESRS is to ensure companies provide high-quality sustainability information that is consistent with financial data. This helps stakeholders understand how sustainability factors shape a business model and long-term resilience.

With ESRS, sustainability information becomes more accessible, enabling better financial and strategic decisions.

What’s New in ESRS Compared to Previous Frameworks?

ESRS introduce new concepts, expanded disclosure requirements, and stricter alignment with financial reporting practices. They replace fragmented practices with a unified european sustainability reporting system.

The new framework also increases accountability and ensures third-party assurance, making sustainability reporting more credible and trustworthy.

ESRS Implementation Challenges for Companies

Companies may face challenges such as building internal capacity, updating systems, managing value chain data, and coordinating information collection across departments. ESRS require strong governance, structured processes, and reliable data sources.

Despite these challenges, many companies see ESRS as an opportunity to strengthen internal processes, reduce risks, and identify opportunities for improvement.

ESRS and Future Developments

As sustainability expectations evolve, ESRS will continue to adapt. Updates will respond to legislative changes, sector-specific needs, and events that reshape sustainability priorities.

Future guidance and technical interpretations will further support organisations seeking clarity on complex topics and disclosure requirements.

Conclusion: The Role of ESRS in Shaping Corporate Accountability

The ESRS represent a transformative shift in sustainability reporting, ensuring that environmental, social, and governance topics receive the same level of attention as financial performance. They reinforce transparency, improve interoperability, and help organisations make better long-term decisions.

As the european commission continues strengthening the sustainability agenda, ESRS will remain at the home of corporate accountability, helping companies ensure responsible and future-proof operations.
