What kinds of principles of justice should a cosmopolitan support? In recent years some have argued that a cosmopolitan should endorse a Global Difference Principle. It has also been suggested that a cosmopolitan should support a Principle of Global Equality of Opportunity. In this paper I examine how compelling these two suggestions are. I argue against a Global Difference Principle, but for an alternative Needs-Based Minimum Floor Principle (where these are not co-extensive, as I explain). Though I support a negative version of the Global Equality of Opportunity Principle, I argue that a more positive version of the ideal remains elusive.

This article attacks the view that global justice should be understood in terms of a global principle of equality. The principle mainly discussed is global equality of opportunity – the idea that people of similar talent and motivation should have equivalent opportunity sets no matter to which society they belong. I argue first that in a culturally plural world we have no neutral way of measuring opportunity sets. I then suggest that the most commonly offered defences of global egalitarianism – the cosmopolitan claim that human lives have equal value, the argument that a persons nationality is a morally arbitrary characteristic, and the more empirical claim that relationships among fellow-nationals are no longer special in a way that matters for justice – are all defective. If we fall back on the idea of equality as a default principle, then we have to recognize that pursuing global equality of opportunity systematically would leave no space for national self-determination. Finally, I ask whether global inequality might be objectionable for reasons independent of justice, and argue that the main reason for concern is the inequalities of power that are likely to emerge in a radically unequal world.

Discussions of where the costs of climate change adaptation and mitigation should fall often focus on the 'polluter pays principle' or the 'ability to pay principle'. Simon Caney has recently defended a 'hybrid view', which includes versions of both of these principles. This article argues that Caney's view succeeds in overcoming several shortfalls of both principles, but is nevertheless subject to three important objections: first, it does not distinguish between those emissions which are hard to avoid and those which are easy to avoid; second, its only partial reference to all-things-considered justice means it cannot provide a full account even of climate justice; and third, it assigns to the poor very limited duties to meet climate change costs, even where they have created those costs, which may incentivise them to increase emissions. An alternative pluralistic account which avoids these objections is presented.

Which political principles should govern global politics? In his new book, Simon Caney engages with the work of philosophers, political theorists, and international relations scholars in order to examine some of the most pressing global issues of our time. Are there universal civil, political, and economic human rights? Should there be a system of supra-state institutions? Can humanitarian intervention be justified?

This essay examines the central claim of Caney's book, viz., that there is no reason to treat the global sphere differently from the domestic sphere. It suggests that there is much that is valuable in having relatively autonomous, differentiated political communities, which both versions of Caney's scope argument ignore. This insight is explored via a critical assessment of both versions of Caney's scope argument; version 1, which is focused on civil and political rights (and argues that that they should be universalized) and version 2, which applies to theories of distributive justice (particularly Caney's global equality of opportunity principle).
