Energy Charter Treaty
The Energy Charter Treaty (ECT) is an international agreement which establishes a multilateral framework for cross-border co-operations in the energy industry. The treaty covers all aspects of commercial energy activities including trade, transit, investments and energy efficiency. The treaty is legally binding, including dispute resolution procedures.Originally, the Energy Charter process was based on integrating the energy sectors of the Soviet Union and Eastern Europe at the end of the Cold War into the broader European and world markets. Its role however extends beyond East-West cooperation and through legally binding instruments strives to promote principles of openness of global energy markets and non-discrimination to stimulate foreign direct investments and global cross-border trade.Awards and settlements of the international arbitrations put forward by breaking the law of the Energy Charter Treaty are sometimes in the hundreds of millions of dollars. In 2014, the nearly-10 year long Yukos case was decided in favor of the claimants on the basis of the Treaty, with a record-breaking $50 billion award.
