New Agreement Marks First Step in Addressing Energy Charter Treaty Legacy

This is an important move to prevent legacy arbitration claims under the treaty, but more remains to be done.

June 27, 2024

June 27, 2024 – Yesterday, 26 European Union (EU) member states signed a declaration and endorsed an agreement on the interpretation and application of the Energy Charter Treaty (ECT), according to a press release published by the Belgian Ministry of Foreign Affairs. The agreement will be published in the Official Journal of the EU shortly, as stated in the release. This is an important step to prevent legacy arbitration claims under the treaty, but more remains to be done.

The new agreement—concluded between the EU, Euratom, and their member states—clarifies the common understanding that the ECT and its investor-state dispute settlement (ISDS) mechanism does not and never did apply within the EU. The treaty has drawn growing criticism from EU member states in recent years as it was used by intra-EU investors to circumvent domestic courts in violation of EU law and to challenge member states’ energy transition policies through ISDS. With more than 160 cases to date, it is the investment treaty that has generated the highest number of ISDS claims.

“This new agreement addresses a significant part of the risks still posed by the ECT, but more action is needed to prevent all fossil fuel arbitrations under the treaty in the future,” says Suzy Nikièma, Director, Sustainable Investment at the International Institute for Sustainable Development (IISD). 

Following a failed attempt to reform the ECT, the EU, Euratom, Germany, France, Spain, Portugal, the Netherlands, Luxembourg, Denmark, Poland, Slovenia, Ireland, and the United Kingdom have decided to leave the treaty. These states generally justified their withdrawal with claims that the reform proposal fell short of their expectations and failed to allow for a decarbonization of the energy sector in line with the timetable warranted by the Paris Agreement. 

However, the treaty contains a so-called survival clause that will continue to allow a wide range of fossil fuel companies and other investors with existing investments to sue states for a period of 20 years after their withdrawal. These are investors from the EU with investments in ECT countries other than the EU (outward), or investors from ECT countries other than the EU with investments in the EU (inward). 

“Granting 20 more years of legal privileges to fossil fuel investors is fundamentally incompatible with climate mitigation. With the new agreement, the EU sends a strong signal to tribunals: ISDS claims within the EU under the ECT lack a legal basis. States should now take this as a precedent for wider steps to prevent such claims among all ECT contracting parties,” says Lukas Schaugg, policy advisor at IISD.

The EU and other non-EU contracting parties of the ECT can minimize the impact of this unusual, far-reaching clause through a further agreement modifying the ECT. Lawyers at IISD and ClientEarth have demonstrated that such an agreement is a viable solution under public international law and model text options will be published shortly.
