A slightly less demanding approach would ask WTO members to approve a waiver to WTO
obligations for trade commitments written in a climate agreement. A waiver, unlike a revision of the text,does not require a consensus among WTO members, but it does require approval from at least three-
quarters of members.Whether this route has much promise largely depends on the extent of overlap
between signatories to the climate agreement and the WTO membership. If a significant number of
WTO members do not sign the climate accord, the prospects of a waiver seem slight.
