Language of the original article: EnglishABSTRACT. This article analyzes sustainability-related financial regulation in the European Union as a density-driven administrative governance framework that expands procedural obligations and supervisory discretion within financial law. Moving beyond conventional interpretations, it conceptualizes Regulation (EU) 2019/2088 (SFDR), Regulation (EU) 2020/852 (Taxonomy Regulation), and Directive (EU) 2022/2464 (CSRD) as structural instruments of regulatory density rather than policy-oriented measures. Through layered disclosure requirements, delegated technical standards, assurance mechanisms, and supervisory integration, these instruments reshape the architecture of financial administrative law across Member States. Using a structured comparative administrative-law methodology, the article examines how Bulgaria and Poland mediate regulatory density through their institutional configurations. The findings demonstrate that harmonized EU norms produce differentiated enforcement outcomes depending on supervisory integration, administrative coordination, and institutional capacity. The article advances the Regulatory Density Governance Model (RDGM) to explain how normative layering and procedural expansion interact with decentralized enforcement in the EU legal order.Keywords: EU financial regulation; administrative law; supervisory discretion; regulatory density; compliance governance; enforcement asymmetry; Bulgaria; Poland.
