This article tries to contribute to the critical debate on the ideological and globalising potential of education for sustainable development (ESD), which exists in the research field of environmental education, by highlighting potential contradictions in the argumentation for ESD's ideological and globalising tendency. Further, the authors of this article argue for an alternative perspective on how education policy on ESD can be seen to contribute to globalisation and homogenisation by merging two conceptualisations of "globalisation as connection" and the role of "empty signifiers" in political discourse. The ambition with the merger is not to provide a universal explanation of globalisation and ideology, instead, the intention is to outline an alternative theoretical outlook that allows for an empirical study of the processes that can be seen to feed into or interrupt the preservation of hegemony in a global setting.
