ABSTRACT
This chapter examines ethical issues relevant to determining each nation’s fair share of safe maximum global greenhouse gas emissions. As we saw in the last chapter, to prevent potentially catastrophic warming from harshly harming some of the poorest people in the world, future generations, and the natural resources on which their life depends, total global greenhouse gas emissions must be low enough to prevent global atmospheric greenhouse gas concentrations from exceeding dangerous levels. We now examine what ethics requires of nations acting in cooperation with other nations to achieve non-dangerous global greenhouse gas atmospheric concentration goals.
