The goals for sustainable development and the new business models under the green label propose significant changes in the modus operandi of consumption and production. Since environmental protection is the main guiding target, they require greater responsibility regarding the social and environmental impacts of the production chains. It is possible to notice the importance of policymakers and legal provisions for the transition to green economies based on a Circular Economy. Despite the economic, social, and environmental advantages, there is deficient legal regulation in Brazil. This study presents the legal approach of the Circular Economy in Brazil, analyzing the challenges of its institutionalization and application. A literature review was conducted to identify studies related to the topic. Throughout the research, we identified the great potential for Brazil regarding the adoption of circular practices, which, however, fails in its normative regulation. As a result, despite the praise given to the National Policy for Solid Waste, there is no enforceable legal norm for the transition from a linear model to a circular production model. However, certifications, control bodies, trade barriers, and the demands of the foreign market itself have been means of encouraging the institutionalization of the Circular Economy in Brazil.
