This study evaluates the degree of regulatory alignment between selected Colombian sustainability disclosure instruments and leading international sustainability reporting frameworks, particularly the International Sustainability Standards Board Standards, the European Sustainability Reporting Standards, and the Global Reporting Initiative Standards. Using a comparative qualitative approach based on regulatory document analysis, the article identifies key areas of convergence, divergence, and normative gaps in the Colombian framework. The results indicate that the Colombian sustainability disclosure system shows evidence of increasing formalization through the incorporation of structured sustainability-related reporting expectations and supervisory guidance. However, the analysis also reveals significant differences in legal force, materiality approaches, sector-specific metrics, and assurance-related provisions when compared with leading international frameworks. The study evaluates regulatory correspondence rather than implementation effectiveness, reporting quality, corporate compliance, or enforcement outcomes.
