True cultural sustainability requires new forms of cultural citizenship in an increasingly globalized world. Such a notion involves both a sense of "planetary" belonging (rather than just to individual nation-states), and a relatedness to nature. This chapter explores the qualities and possibility of cultural citizenship and its relations to sustainability, and the emerging idea of the "ecological self". It links this back to the issues of political culture discussed in the previous chapter. To notions of cultural and civilizational dialogue currently espoused by the UN, and to new ideas of "cosmopolitan citizenship" in which responsibility and well as rights form the core.
