Understanding the difference between ESG and ESRS reporting

ESG and ESRS reporting

While they share common letters and goals, their structures and applications differ significantly. Here’s what you need to know:

What is ESG?

ESG reporting provides insight into an organisation's impact on the environment, society, and its governance practices. It is a flexible framework used by companies globally to communicate sustainability performance to stakeholders, including investors.

ESG emerged as a way for investors and businesses to simplify and structure their sustainability approaches, with guidelines promoted by organisations such as Nasdaq. Rather than prescribing a specific set of rules, ESG defines the categories, Environmental, Social, and Governance, against which a company's performance is evaluated.

Its key characteristics are breadth and flexibility. ESG covers environmental factors such as carbon footprint and resource use, social factors such as employee welfare and diversity, and governance factors such as corporate ethics and board composition. It is adaptable across industries and regions and, in most contexts, remains voluntary, though investor and stakeholder expectations increasingly make it a practical requirement.

What is ESRS?

The European Sustainability Reporting Standards (ESRS) are the reporting standards underpinning the EU's Corporate Sustainability Reporting Directive (CSRD). Where ESG is a broad framework, ESRS is a detailed, mandatory set of requirements for how qualifying EU companies must collect and disclose sustainability data. Clarifying these distinctions can help you navigate compliance confidently.

The European Parliament adopted the CSRD on 10 November 2022 and came into effect on 5 January 2023. It established a legal obligation for companies meeting certain criteria to report on environmental, social, and governance matters, and ESRS defines precisely how that reporting must be structured and what it must cover. ESRS addresses environmental, social, and governance matters in detail, guiding companies on data collection and disclosure. Its purpose is to standardise sustainability reporting across the EU, ensuring consistency and comparability across organisations and sectors.

A note on recent developments: the ESRS framework is currently being revised under the EU Omnibus directive (EU 2026/470), adopted in February 2026. The revision is expected to significantly reduce the number of mandatory data points and remove sector-specific standards. Companies should monitor these developments, as the scope of ESRS reporting obligations continues to evolve.

Key differences

The most fundamental distinction is one of scope and obligation. ESG is a globally recognised, broadly flexible framework, voluntary in most contexts and adaptable to different industries and regions. ESRS is EU-specific, tied directly to the CSRD, and mandatory for qualifying companies. Recognising these differences can help you focus your compliance efforts effectively.

Understanding that ESG offers general metrics while ESRS mandates detailed, standardised disclosures helps professionals determine their reporting scope. This clarity supports compliance and accurate data collection for their organisations. Their audiences also differ in emphasis. ESG reporting is primarily oriented toward investors, stakeholders, and the general public; it is a communication tool as much as a compliance mechanism. ESRS is directed first at regulatory bodies, with investor and stakeholder communication as a secondary output.

Which should you focus on?

For global companies, ESG remains an important tool for communicating sustainability performance to a broad audience. For organisations operating within the EU or engaging with European markets, ESRS compliance is the more pressing obligation, though the scope of who must comply continues to evolve.

In practice, the two frameworks are not in competition. ESG provides a common language; ESRS provides the EU's regulatory structure for its rigorous application.
