ESG Reporting

ESG Reporting refers to the disclosure of a company’s environmental, social, and governance (ESG) performance, helping stakeholders assess sustainability risks and impacts. Depending on company size, regulatory obligations, and audience, ESG reports can take different forms: Mandatory Reports: -> CSRD (Corporate Sustainability Reporting Directive) – Mandatory for large and listed EU companies, requiring detailed ESG data in line with European Sustainability Reporting Standards (ESRS). Voluntary Reports: -> LSME (Large & Listed SMEs) – Mid-sized companies preparing for future reporting obligations. -> VSME (Voluntary SME Reporting) – Small businesses opting for streamlined, non-mandatory ESG disclosures to improve transparency and market positioning. More detailed overview of Frameworks & Standards can be found in guide - Sustainability Reporting and Disclosure. Types of Reports: -> Data-Driven ESG Reports – Factual, compliance-focused reports designed for regulators and investors (e.g., CSRD-compliant disclosures). -> Marketing-Oriented ESG Reports – Designed for branding and reputation management, often focusing on storytelling rather than deep compliance data. Effective ESG reporting ensures compliance, builds trust with stakeholders, and enhances access to sustainable finance. The right approach depends on regulatory requirements, investor expectations, and business strategy.

Legislation

The Corporate Sustainability Reporting Directive (CSRD) is a directive by the European Union that replaces the Non-Financial Reporting Directive (NFRD), significantly expanding the scope and depth of corporate sustainability reporting requirements. It requires companies to report on the impact of their activities on the environment and society and mandates the audit of the reported information to ensure reliability and transparency. This directive is part of the EU’s broader goal to integrate sustainability into corporate governance and align with the European Green Deal objectives​. Scope of Application: -> CSRD applies to all large EU companies, all listed companies (except micro-enterprises), and non-EU companies operating within the EU. This includes companies meeting certain size thresholds under Directive 2013/34/EU​​ -> Small and medium-sized enterprises (SMEs) may opt into voluntary reporting based on future standards​​ Double Materiality Principle: Companies are required to report on the financial risks and opportunities arising from sustainability issues and their impact on society and the environment. This approach is central to the European Sustainability Reporting Standards (ESRS)​​ Reporting Standards (ESRS): Companies must comply with European Sustainability Reporting Standards (ESRS). These cover general requirements, disclosures, and topic-specific issues, such as climate change (E1), biodiversity (E4), and business conduct (G1). The ESRS were developed by EFRAG based on stakeholder input​​​ Streamlined Reporting: CSRD aims to reduce reporting burdens by phasing in requirements and ensuring compatibility with existing regulations like the Taxonomy Regulation and Sustainable Finance Disclosure Regulation (SFDR)​​ Alignment with International Standards: ESRS are aligned with global frameworks like the GRI Standards and ISSB to ensure interoperability and reduce redundancy​​ Materiality Assessment: Companies must perform a robust materiality assessment, identifying significant sustainability impacts, risks, and opportunities across their operations and value chains​​ Digital Reporting and Assurance: Encourages the use of digital taxonomies to facilitate seamless data integration and emphasizes external assurance of sustainability data to enhance reliability​​ *UPDATE: The European Commission's "Simplification Omnibus" package, introduced in February 2025, proposes significant changes to the Corporate Sustainability Reporting Directive (CSRD) to reduce administrative burdens and enhance competitiveness. Key proposed changes: 1/ Reduced Scope of Applicability To applicable only to companies with over 1,000 employees and either: -> €50 million in net turnover, or -> €25 million in total assets. 2/ Delayed Reporting Deadlines -> Second-wave companies: Reporting postpone from 2026 to 2028. -> Third-wave companies: Reporting postpone from 2027 to 2029. 3/ Simplified Reporting Standards (ESRS) Revisions to the European Sustainability Reporting Standards include: -> Reduction in required data points -> Elimination of sector-specific standards -> Prioritization of quantitative over narrative disclosures 4/ Voluntary Reporting for Smaller Companies Companies with fewer than 1,000 employees are no longer mandated to report but can opt to do so using a simplified voluntary standard developed by EFRAG 5/ Assurance Requirements Maintained at Limited Level The anticipated shift from limited to reasonable assurance has been removed. Companies will continue with limited assurance, reducing compliance costs.​ ​The European Commission's "Stop-the-Clock" proposal, part of the broader Omnibus Simplification Package, intend to agree on postponement of the directive. 🔗 EP, EC, EFRAG

The EU Taxonomy Regulation (Regulation (EU) 2020/852) establishes a classification system to identify environmentally sustainable economic activities, aiming to direct investments toward the EU's environmental objectives. It defines six environmental objectives: -> Climate change mitigation -> Climate change adaptation -> Sustainable use and protection of water and marine resources -> Transition to a circular economy -> Pollution prevention and control -> Protection and restoration of biodiversity and ecosystems 1/ EU Taxonomy Regulation (EU) 2020/852 is the Regulation that sets the overall framework and objectives for what constitutes "environmentally sustainable" activities in the EU. 2/ The Delegated Acts are the detailed technical regulations that provide the specific criteria and thresholds for various environmental objectives (climate mitigation, water protection, biodiversity, etc.). These Delegated Acts support the implementation of the Taxonomy Regulation. The EU Taxonomy is an essential part of the EU's sustainable finance framework. It serves as a classification system to define environmentally sustainable economic activities based on science-based criteria. Its primary goals are to help investors, companies, and financial institutions identify and finance projects and activities that align with the EU's environmental objectives, such as climate change mitigation and adaptation, circular economy promotion, and biodiversity protection​ The EU Taxonomy is not a mandatory list for investors to invest in. It does not set mandatory requirements on environmental performance for companies or for financial products. Investors are free to choose what to invest in. However, it is expected that over time, the EU Taxonomy will encourage a transition towards sustainability in order to achieve the EU’s climate and environmental goals. The Taxonomy sets performance thresholds (referred to as ‘technical screening criteria’) for economic activities which: -> make a substantive contribution to one of the above six environmental objectives; -> do no significant harm (DNSH) to the other five, where relevant; -> meet minimum safeguards (e.g., OECD Guidelines on Multinational Enterprises and the UN Guiding Principles on Business and Human Rights) 🔗 European Commission

Guide

Sustainability Reporting and Disclosure (SRD) is no longer a voluntary "nice-to-have" element—it’s become a strategic imperative. Companies today are expected to disclose comprehensive data on their environmental, social, and governance (ESG) performance. This guide provides a structured approach to understanding SRD, the regulatory landscape driving its adoption, the tools and methodologies that underpin best practices, and actionable steps that organizations can take to leverage sustainability reporting as a strategic advantage.

What Is Sustainability Reporting and Disclosure?

Sustainability Reporting and Disclosure involves compiling and presenting data on a company’s non-financial performance, including its environmental impact, social responsibilities, and governance practices. Modern reporting methods focus on:

  • Double Materiality: An approach that examines both the impact of a company on society/environment (inside-out) and how external ESG factors affect the business’s financial performance (outside-in).

  • Integrated Reporting: Combining traditional financial data with ESG performance metrics to give stakeholders a holistic view of corporate value and risk.

  • Assurance: Independent audits or third-party verification processes to lend credibility and transparency to the disclosed information.

By adopting these methods, companies can not only ensure compliance with emerging regulations but also communicate their commitment to sustainable practices.

Guide

The European Union (EU) and world financial markets are currently experiencing an explosion of sustainability reporting standards, most notably the International Sustainability Standards Board (ISSB, established by the global accounting standard-setter International Financial Reporting Standards, IFRS) and the European Sustainability Reporting Standards (ESRS, an outcome of the Corporate Sustainability Reporting Directive, CSRD). Both link financial reporting statements with sustainability disclosures to strengthen investor protection, reduce greenwashing and ensure reliable and comparable disclosures that meet the information needs of investors and other stakeholders.

Following is a summary of how to approach and implement reporting systems to meet your obligations under these new standards.
