<p>This article-dialogue explores global citizenship education (GCE) as a form of planetary ethics. It features Carlos Alberto Torres, distinguished professor and former director of the UCLA-Latin American Center in the United States, and Emiliano Bosio, guest editor of <i>Prospects</i> and director of the Global Citizenship Education Interview Series. Taking an ethical planetary perspective, the article proposes a paradigm shift that expands the scope of GCE beyond a focus solely on human beings to one that encompasses the interdependence of animals, the environment, and the overall well-being of the planet. First, it argues that Bosio and Torres’ concept of a global commons (planet, people, and peace) constitutes the three fundamental elements for a GCE grounded in planetary ethics, particularly in the face of what Torres refers to in this article as a “crisis of civilization”, encompassing moral, human rights, immigration, multiculturalism, deregulation, planetary, and epistemological crises. Second, it examines the concept of the pursuit of happiness in education and its significance in relation to our discussion of GCE as a form of planetary ethics. Third, it proposes that values such as tolerance, self-vigilance in knowledge acquisition, self-awareness, dialogical and deliberative democracy, and hermeneutics of suspicion should be integrated into a future-oriented pedagogy for GCE as planetary ethics. The article concludes by arguing that these values should be translated into practical initiatives that promote social justice.</p>
