Justice entitles everyone in the world, including future generations, to an equitable share of the benefits of the world's natural resources. I argue that even though both Rawls and his libertarian critics seem hostile to it, this resource equity principle, suitably clarified, is a major part of an adequate strict compliance theory of global justice whether or not we take a libertarian or a Rawlsian approach. I offer a defence of the resource equity principle from both points of view.
