Agreement in Principle on the modernised ECT is of systemic relevance for climate action

On 5 September 2022, the United Nations Conference on Trade and Development (UNCTAD) released a new IIA Issues Note analysing climate change-related provisions in existing treaty practice and offering various reform policy options for drafting climate-responsive International Investment Agreements (IIAs).

The Issues Note further refers to the 24 June 2022 Agreement in Principle on the modernisation of the Energy Charter Treaty (ECT) and its provisions relevant for the protection of the environment, climate action and sustainable development, concluding that it is “of systemic relevance for IIA reform and climate action”. The ECT, with more than 50 Contracting Parties including the EU/Euratom, is not just an investment agreement (considered as a risk mitigation mechanism for investments in the energy sector by institutions such as the World Bank Multilateral Investment Guarantee Agency, MIGA) but also regulates energy transit, transfer of technology, environment, and other key aspects of international energy cooperation.

The Agreement in Principle not only implements most of the reform policy options suggested by UNCTAD as relevant for climate action, but it could also be considered the first coordinated multinational effort to successfully implement a comprehensive review aligned with the Paris Agreement. Some of the relevant provisions of the Agreement in Principle (in addition to the application of the UNCITRAL Rules on Transparency and provisions on security for costs, frivolous claims and valuation of damages) are:
