Holding Transnational Corporations Accountable for Environmental Harm Through Counterclaims in Investor-State Dispute Settlement: Myth or Reality?

Abstract

Abstract Considering the imperative need to protect our environment, the present article begins by highlighting the absence of a comprehensive international framework under which transnational corporations may be held accountable for environmental harm. Drawing from the successful decisions on environmental counterclaims in Perenco v Ecuador and Burlington Resources v Ecuador, this article thus argues that this legal void could be filled by holding transnational corporations accountable for environmental harm under international investment law. However, the practice of environmental counterclaims as they have materialised in these recent decisions emphasises the existence of a gap between theory and reality and, thus, their limited chances of success. It is nevertheless suggested that, in the context of current debates surrounding an investor-State dispute settlement reform, States hold the cards to ensure that transnational corporations are held accountable for environmental harm under international investment law.
