This paper elucidates the inseparable connection between the pursuit of a more ecologically sustainable society and the quest for socioeconomic justice. It also demonstrates why Unconditional Basic Income (UBI) is an effective policy to act on both fronts. First, the corresponding theory on environmental and socioeconomic oppression sheds light on the argument that both types of domination stem from the same historical process and are inherently interconnected. Addressing one without considering the other is essentially flawed; they are both features and consequences of present society. Acknowledging the historical debt owed to vulnerable economic classes and developing countries is imperative. Green republicanism could potentially establish a theoretical foundation for social-ecological thinking. Defining freedom as non-domination and applying this concept to nature are essential prerequisites for overcoming socioeconomic and environmental oppression. UBI is presented and discussed theoretically as a strong solution to address these two challenges. It serves not only as a means to facilitate the transition to a post-productivist society, transforming labor relations, but also as a catalyst for the development of circular economies and more sustainable occupations. Additionally, the basic income policy implemented in the city of Maricá, Brazil, is cited as empirical evidence showcasing the environmental and socioeconomic values of UBI.
