Retooling the Energy Charter Treaty for climate change mitigation: lessons from investment law and arbitration

In 2017, the Energy Charter Treaty (ECT) began a modernization process aimed at updating, clarifying, and modernizing a number of provisions of the Treaty. Considering the scope of application of the Treaty—cooperation in energy trade, transit, and investment—there is hardly any doubt that the modernization kicked off in 2017 offers a springboard for constructive reform and a unique opportunity to bring the Treaty closer in line with the objectives of the Paris Agreement. Although none of the items selected by the Energy Charter Conference and open for discussion and reform mention climate change or clean energy, a careful analysis of the relevant practice in both treaty drafting and adjudication can provide valuable insights as to how to steer the discussions on some of the existing items in a climate-friendly direction. The purpose of this article is to rely on this relevant practice to explore promising avenues to ‘retool’ the Treaty for climate change mitigation, in other words, to imagine a Treaty that would better reflect climate change concerns and clean energy transition goals.
