We have drawn two propositions, critical from a developing country viewpoin
t, from the trade and environment literature and assessed them for cloth an
d leather production in Pakistan. The first is that trade liberalization wi
ll result in export by developing countries of their environmental capital.
The second is that the costs of mitigating these damaging environmental ef
fects in the South are very high. We find that, given the state of implemen
tation of environmental laws in Pakistan, exports induced by trade liberali
zation can indeed have major negative environmental impacts. However, we do
not find support for the proposition that the costs of mitigation are very
high. We also find that the social benefits far exceed the costs of mitiga
tion.
