The Global Fund is a mechanism for the global application of the Left Libertarian conception of distributive justice. As a form of luck egalitarianism, this conception confers upon each person an entitlement to an equal share of all natural resource values, since natural resources – broadly, geographical sites – are objects for the production of which no person is responsible. Owners of these sites, i.e. states, are liable to a 100% Global Fund tax on their unimproved value: that is, their gross market value minus the value of the improvements added to them by human effort. It is argued that the revenue yielded by this tax would be correspondingly reduced by a further tax on the use of natural resources.
