The international community has acknowledged that international trade can be an effective means of helping to achieve the 2030 Agenda for Sustainable Development and its 17 Sustainable Development Goals (SDGs). Traditionally, preferential trade agreements (PTAs) were designed to promote trade flows. PTAs have become more comprehensive and now also cover non-economic policy areas, such as the environment. This chapter examines whether the inclusion of environmental provisions in PTAs changes the observed overall positive contribution that PTAs make to economic outcomes and thereby to the economic objectives of the SDGs. Specifically, we ask whether the inclusion of environmental provisions in PTAs reduces export flows between PTA partner countries. Using a novel data set on environmental provisions in PTAs, we estimate gravity type panel regressions. We find that membership in PTAs including more environmental provisions is associated with less trade among trade partners compared to PTAs that include less or no environmental provisions. This negative effect of environmental provisions is fully driven by the negative effect on South–North trade flows, i.e. exports from developing to high-income countries.

Preferential trade agreements (PTAs) cover a much wider diversity of environmental clauses than World Trade Organization (WTO) agreements. Which PTA environmental clauses could be multilateralized and included in the WTO rulebook? This chapter compares five different scenarios for the potential multilateralization of PTA environmental clauses: (1) The “routine scenario” combines the most frequent clauses, (2) the “consensual scenario” includes the clauses accepted by a high number of WTO members, (3) the “trendy scenario” includes the most popular clauses in recent times, (4) “the power-game scenario” combines the clauses that are jointly supported by the United States and the European Union, and (5) the “appropriate scenario” is a compilation of the clauses typically included in large membership agreements. This chapter compares and contrasts the implications of each scenario and identifies their common ground. Although each scenario represents an ideal type unlikely to materialize, the comparison offers insights into how the multilateral trading system could be developed to improve the integration of environmental concerns.

This chapter first characterizes the fundamental purposes of the WTO and trade agreements, which should be viewed as much broader than trade liberalization. It then presents the major challenges that the trade system now faces. Special emphasis is paid to technological change since the WTO was created in 1995, namely, the development of global value chains. Finally, the author contends that trade agreements, in response, must be designed and conditioned upon social policy commitments. They should include, or be conditioned upon, agreements that cover: coordinated tax policy to combat harmful tax competition, tax avoidance, and tax evasion; domestic social security and job retraining, supported by trade adjustment commitments; labor protection; protections against social dumping; and accommodation of industrial policy experimentation for development. It will not be an easy process to reconceive trade agreements to better ensure social inclusion through these means, but the current system otherwise could unravel.
