Issue Brief on the World Trade Organization Supremacy Clause in the POPs Convention

The briefing paper examines the risks of including a WTO supremacy clause in the draft POPs Convention, specifically in article N bis. It argues that such a clause would subordinate environmental goals to trade rules, undermine existing WTO environmental exceptions, and inappropriately grant the WTO dispute settlement body final authority over environmental policy. The author contends that the POPs negotiations are the correct forum for balancing trade and environmental measures and that existing international treaty interpretation laws make a supremacy clause unnecessary.

• The proposed supremacy clause in article N bis of the draft POPs Convention states that the Convention's provisions "shall not affect the rights and obligations of any Party deriving from any existing international agreements," which would likely make international trade law automatically superior to the POPs Convention.
• Including a supremacy clause could undermine the current consensus at the WTO that environmental exceptions—which allow countries to protect human, animal, and plant life and health—apply to measures developed through multilateral environmental agreements.
• The WTO dispute settlement body (DSB) is deemed an inappropriate forum for resolving conflicts between the POPs Convention and trade rules because its panels consist of trade experts who lack the necessary expertise in environmental policy and sustainable development to impartially balance interests.
• A supremacy clause is unnecessary because the Vienna Convention on the Law of Treaties provides international rules for treaty interpretation that can resolve conflicts between the POPs Convention and other international agreements.
