The purpose of this paper is to establish the limits of the cost-benef
it framework used by environmental economists given the acceptance of
an ethic of environmental concern. Two approaches to environmental eth
ics will be considered - one based on the view that human beings are t
he focus of moral concern, and another based on the notion that moral
concern can be extended to the non-human natural world as well. If hum
an beings are morally considerable, cost-benefit analysis can be legit
imately applied to environmental issues involving the pursuit of human
well-being so long as those who suffer losses from environmental dama
ge are adequately compensated. However, the application of cost-benefi
t analysis to environmental issues is inconsistent with the moral cons
iderability of human beings in cases where environmental damage is har
mful to human health and in cases where the natural environment is so
highly valued that the compensation of damaged parties is infeasible.
Moreover, cost-benefit analysis cannot be legitimately applied where n
on-human natural entities are viewed as morally considerable.
