The present study sought to analyze, from a decolonial perspective, how and why Eurocentric standards were adopted by the consumerism movement in Brazil and the colonialist consequences of this process. To achieve the proposed objective, three articles were developed, which addressed discussions related to modernity/coloniality/decolonialism; consumerism and consumerist movement; and an empirical study of a Brazilian consumer organization. The literature on decolonialism and consumerism was reviewed, in which it was evident the resistance of the marketing area to address the topic of consumerism in research and the low presence of studies that use alternative perspectives to those originated in the Global North to analyze consumption phenomena, even those of a critical nature. In the case of Proteste, it was identified that the organization s consumerist practices reflect the coloniality practiced by Eurocentric organizations, which influence consumerism in Brazil by imposing the model of consumerism practiced in the Global North, ignoring the particularities of the Brazilian market and the needs of the population that does not relate to consumption. Based on interviews and secondary data, the analysis demonstrated how Proteste deals with the hierarchy created within Euroconsumers, positioning it at the bottom of this structure, as well as adopting the Eurocentric universalist consumerist knowledge, which does not necessarily contribute to solving the issues consumers in Brazil. The decolonial perspective can contribute to identifying the coloniality present in the Eurocentric influence on the consumerist movement, highlighting the imposition of knowledge from the Global North on the subject, seen as universal, and ignoring the needs of the Brazilian consumer, which are not treated in depth. Thus, the Brazilian consumerist movement focuses on issues related to the choice of products and services, valuing the transactional stage of consumption, leaving aside the well-being and basic needs of the consumer.
