Green Shoots in a Barren World: Recent Developments in International Investment Law

Abstract

AbstractThis article begins from the observation that there have been a number of developments in international investment law-making and the jurisprudence of investor-state dispute settlement tribunals involving the protection of the environment and human rights. As for law-making, this article explores the evolving substance of international investment agreements as well as regulatory developments in the area of business and human rights that are of relevance to the international investment law framework. The article then turns to consider the emergence of human rights and environmental issues in the recent jurisprudence of investment tribunals and appraises how such issues have been dealt with—both in procedural and substantive terms—by arbitral tribunals. Finally, it questions whether investment tribunals are appropriate venues for the adjudication of non-investment matters like environmental and human rights issues, and highlights best practices that could be adopted by future tribunals. Overall, the article concludes that the piecemeal approach adopted to date provides a step in the right direction but is ultimately inadequate given the multiple challenges that our planet currently faces. Rather, a more ambitious agenda that is concerned with promoting good investment, as opposed to mitigating bad practices, should be pursued.
