The inclusion of environmental provisions can spark con­troversies. For some, the inclusion of environmental pro­visions offers untapped potential for actual environ­mental protection, making these agreements more compatible with environment and climate policies. However, trade critics often see these provisions as mere “fig leafs” that are included in modern PTAs in order to make them less controversial in the eyes of the public and legislators. For other critics, they represent an instrument of “green protectionism” in order to keep cheaper products from developing countries out of the market.

Given the newness of the widespread inclusion of environmental provisions in PTAs and the heated debate that is raging about the nature and effects of trade policies, better data and research is needed to understand and analyse this development.

Firstly, we need to improve our understanding of the specific design of these new rules and the related policy initiatives of PTA signatories. What drives the inclusion of environmental provisions in trade agreements? Which are the most innovative agreements and which the most innovative countries in terms of including environmental provisions in PTAs? Which environmental provisions are diffused more often than others into subsequent PTAs?

Secondly, there is a need to understand the interplay between PTAs and other environmental or climate agree­ments. To what extent do PTAs with environmental pro­visions serve the purpose of multilateral environmental agree­ments (MEAs) or the Paris Agreement on climate change?

Last but not the least: What are the implications of environmental provisions? Does the inclusion of these provisions in PTAs help the contracting parties to implement domestic environmental laws?

The innovative and interactive online tool TREND analytics based on the Trade & Environment Database (TREND), which tracks almost 300 different environmental provisions in the texts of about 630 PTAs, offers new ways of going further and of undertaking research to generate fine-grained information on the interplay between trade and the environment, providing fresh insights into a number of relevant policy discussions. This Briefing Paper summarises recent research results based on TREND, along with providing new insights into these questions and policy discussions at the interface of international trade and the environment.
