From voluntary CSR to binding ESG frameworks: a legal perspective on sustainability disclosure standards

Key findings from this study

• The authors propose that ESG governance has shifted from voluntary, ethics-based CSR frameworks to binding legal disclosure obligations, with this transition varying significantly across jurisdictions.
• The study identifies substantial fragmentation and definitional inconsistencies across global ESG standards, ratings, and regulatory frameworks that hinder organizational compliance and reporting comparability.
• The review establishes a typology of ESG authority distinguishing regulatory, institutional, and market-driven instruments, revealing overlapping and uncoordinated normative mechanisms.

Overview

This article examines the legal transformation of environmental, social, and governance (ESG) regulation from voluntary ethics-based corporate social responsibility (CSR) initiatives to binding legal disclosure obligations. The study contrasts transatlantic regulatory approaches, with the USA maintaining predominantly voluntary ESG frameworks while the European Union implements mandatory reporting requirements. The authors identify significant fragmentation, definitional inconsistencies, and power asymmetries across global ESG governance structures.

Methods and approach

The authors conducted a comparative legal analysis of ESG governance mechanisms across jurisdictions. They developed a typology distinguishing binding from non-binding frameworks and de jure from de facto instruments. The analysis traced the historical evolution from CSR to ESG standardization, examined divergent disclosure regimes between the USA and EU, and assessed definitional and methodological challenges within existing ESG standards and ratings.

Results

The study identifies fundamental structural differences in ESG regulation between the USA and EU. The USA relies on market-driven, voluntary disclosure mechanisms, while the EU has progressively mandated ESG reporting through binding legal frameworks. The authors demonstrate that current global ESG governance exhibits considerable fragmentation, with inconsistent definitional standards, methodological variations in ratings systems, and overlapping regulatory instruments creating compliance complexity.

The research establishes a legally grounded typology of ESG authority encompassing regulatory, institutional, and market-driven instruments. This classification reveals that ESG governance operates across multiple overlapping normative layers without coherent coordination. The authors document how standards proliferation—including both binding and non-binding frameworks—generates ambiguities that impede organizational compliance and comparative reporting across jurisdictions.

Implications

The fragmented regulatory landscape creates substantial compliance burdens for multinational organizations navigating divergent disclosure requirements. Greater interoperability and harmonization of ESG standards would reduce duplication, decrease compliance costs, and enable consistent cross-border comparability. The authors argue that coherent legal frameworks and coordinated standard-setting mechanisms are necessary to support organizational accountability and transparent ESG reporting.

The study underscores that the juridification of sustainability through binding legal obligations represents a fundamental departure from earlier voluntary CSR models. This shift necessitates clearer definitional standards, methodological consistency, and coordinated regulatory architecture at the global level. The research suggests that policymakers must address power dynamics and institutional gaps currently shaping ESG governance to establish legitimate, effective sustainability disclosure regimes.
