The rules of the WTO and MEAs

The rules of the WTO and MEAs

Consider, first, how the rules of the WTO and MEAs may intersect.
In this regard, the WTO notes that ‘It has been widely recognized by both environmental and trade policy-makers that multilateral solutions to transboundary environmental problems, whether regional or global, are preferable to unilateral solutions are preferable to unilateral solutions’. How is this reflected in WTO jurisprudence and do the rules of the WTO foster or hinder the enforcement and/or implementation of MEAs?
