Abstract
Although there are many theories of justice, one crucial feature of those that are most widely accepted is that they lay down principles that determine the allocation of rights and obligations in society. They do not eliminate conflicts of interest between different groups but, by specifying such principles, they are designed to enable conflicting interests to be resolved in a peaceful and harmonious manner. But insofar as future generations cannot be said to have any rights, their interests cannot be protected within the framework of any theory of intergenerational justice. This chapter discusses the general relationship between ‘rights’ and ‘justice’, and the obstacles to any theory of intergenerational justice.
