The Energy Charter Treaty
The Energy Charter Treaty is an energy investment agreement that has grown into an obstacle to impactful climate policies—and a safeguard for the fossil fuel industry. In April 2024, the European Parliament voted for the European Union's historic withdrawal from the ECT, following Germany, France, and the UK's earlier exits. IISD has consistently promoted this outcome—both publicly and behind the scenes. We are now leading the work on neutralizing the ECT's 'sunset clause' through tailored legal solutions.
The Energy Charter Treaty (ECT), introduced in 1994, is an international investment treaty in the energy sector spanning Europe and parts of Asia. Today it is widely recognized as an obstacle to the green energy transition and a safeguard for the fossil fuel industry.
The ECT has attracted more investor-state dispute settlement (ISDS) claims from fossil fuel companies against states than any other investment treaty, costing governments hundreds of millions of dollars for introducing climate change policies.
In a historic vote on April 24, 2024, the European Parliament voted for the European Union's (EU) withdrawal from the ECT. This followed withdrawal announcements from Germany, France, Spain, the Netherlands, the United Kingdom and a host of EU member states.
The vote was preceded by a European Commission's proposal for a coordinated withdrawal by EU, its member states, and Euratom from the ECT, which cited the treaty's incompatibility with the EU's climate targets under the European Green Deal and the Paris Agreement.
IISD has consistently driven the conversation on the ECT, advanced withdrawals by the EU and states, and provided legal advice to policy-makers on how to execute their decisions. We have acted both publicly and behind the scenes, through in-depth research, live analysis, regular events, direct outreach to decision makers, and awareness-building across civil society and media—including with Financial Times, the Guardian and Reuters.
IISD is now leading the work on neutralizing the ECT's 'sunset clause', which attempts to protect existing investments for a further 20 years after states' withdrawals, through advancing tailored, so-called inter se agreements.
In addition, we are working to prevent the model from being replicated in regions of the Global South.

IISD’s research on the Energy Charter Treaty has featured in media coverage across Europe, including in the Financial Times, Politico, Reuters, and Deutsche Welle. We have co-authored op-eds and blogs published in Euractiv, German Verfassungsblog, and Der Standard.

Beyond the Energy Charter Treaty: job half done? - European Energy Innovator
"The EU's exit is 'a job halfdone' unless member states address the sunset clause with the UK. The 2021 ECJ ruling sets a helpful precedent here, Lukas Schaugg, policy advisor at the International Institute for Sustainable Development, said during a panel in June. In August his organisation published a model inter-se agreement proposal for the EU and other exiting members."

"The vote was 'historic', said Lukas Schaugg, international law analyst at the International Institute for Sustainable Development.

MEPs vote to leave treaty used by investors to sue over climate policies - the Guardian
"Lukas Schaugg, a lawyer at the International Institute for Sustainable Development, a thinktank, said: 'Fossil fuel investors have used the ECT to challenge government climate measures through investor-state dispute settlement (ISDS) more frequently than any other investment treaty. With its vote for the EU to leave the ECT, the European parliament underlines that granting fossil fuel companies privileged access to ISDS is fundamentally incompatible with climate mitigation.'”
