As a whole, the Green New Deal (GND) is discussed as one of the most promising political projects to address social justice targets together with climate goals. Yet, as most individual GNDs focus on the national level, concerns about global justice have largely remained absent from early debates, leading some to conclude that the GND reproduces neocolonial and extractivist schemes. To analyse programs for a GND in relation to issues of global justice requires an analytical framework able to evaluate justice claims in extended geographies. Drawing on the later work of political theorist Iris Marion Young, we develop a framework that foregrounds three principles: shared responsibilities for environmental harm of global reach, self-determination for those effected by these harms, and a forward-looking political responsibility to address the structures producing and sustaining injustice. We employ this framework to conduct a qualitative content analysis of four selected GND proposals from the UK, the EU and the US. This analysis indicates that all selected GNDs acknowledge in principle the global reach of responsibilities and formulate (limited) proposals to address these in different fields. However, they do not think of global justice in terms of a forward-looking notion of political responsibility that acknowledges the need of structural reforms and the self-determination of those experiencing harm. Instead, when addressing justice beyond the level of the nation state, these GNDs fall back on a notion of distributive justice. Based on the work of Young, we conclude with a set of propositions for global democratic structures that would support the outlined principles of global justice.
