Transatlantic Convergence of PTAs’ Environmental Clauses

Abstract

The United States (US) and the European Union (EU) include several environmental clauses in their respective preferential trade agreements (PTAs). Building on an exhaustive and fine-grained dataset of PTAs environmental clauses, this article makes two contributions. First, it show that the US and the EU have initially favored different approaches to environmental protection in their PTAs. US concerns over regulatory sovereignty and level playing field have conducted to a legalistic and adversarial approach, while EU concerns for policy coherence have led to a more procedural and cooperative approach. Second, this article provides evidence that European and American trade negotiators have gradually converged on a shared set of environmental norms. Although the US and the EU initially pursued different objectives, they learned from each other and drew similar lessons. As a result, recent American agreements have become more European-like, and European agreements have become more Americanized. This article concludes that US and EU approaches, far from being incompatible, can usefully be combined and reinforce each other.
