The antiglobalization movement (AGM) focuses on action directed against neoliberal economic globalization. It shuns theory and theorizing; yet to deserve intellectual credit, it needs such a foundation and a perspective on the alternative it offers. In addition to its current forms of critique of economic policy, this article argues that the AGM also needs a far more elaborate and radical articulation of its environmental interests. Both as a form of reflection on its possible aims and as a useful tool in an academic analysis of the (in)consistencies of AGM critique, the author introduces a new research tool—“controlled” or “laboratory” utopianism—and illustrates the use of this tool by giving an outline and critique of the AGM’s implicit vision of a better world (Globotopia) by combining the ideals defended by the movement.
