The Energy Charter Treaty (ECT) is a multi-party investment treaty covering investment in the energy sector. Established in the 1990s, the ECT has over 50 signatories, including the UK. The ECT contains many of the traditional protections for foreign investment found in international investment agreements (IIAs), and much like international investment law generally, the treaty has been subjected to widespread criticism in recent years. The ECT has been particularly vilified for its alleged failure to deal with climate change by maintaining extensive protections for industries that supposedly contribute to this global problem.
