Abstract

This study conducts a comparative qualitative analysis of the regulatory frameworks governing the use of animals in education and research in Brazil and the European Union, focusing on ethical, legal, and technical aspects related to animal welfare. Through a chronological and structural examination of key documents - Directive 2010/63/EU and its updates in the EU, and Law No. 11.794/2008 with its normative resolutions in Brazil - the research evaluates similarities, differences, and advances in both systems. Findings show that the European Directive establishes a comprehensive and harmonized framework, encompassing vertebrates and cephalopods, and promoting transparency through nontechnical summaries and public data on animal use. Brazilian regulation demonstrates notable progress, supported by detailed operational standards and oversight by CONCEA and CEUAs, but remains limited to vertebrates and lacks comparable mechanisms for public transparency. Both regions exhibit strong adherence to the principles of Replacement, Reduction, and Refinement (3Rs), reflecting a shared ethical commitment to humane scientific practices. The study concludes that while Brazil and the EU differ in scope and implementation, both legal systems represent significant achievements in the governance of animal use. Continued harmonization, personnel training, and the development of alternative methods are essential to strengthen ethical standards in science and education.
