Launched in February 2021, a petition asking the EU to pull out from the ECT collected over 1 million signatures in just a few weeks.

In July 2021, 402 worldwide civil society organisations published a new statement asking their governments to exit the Energy Charter Treaty by COP26.

In December 2019, 278 civil society groups and trade unions from member states of the Energy Charter Conference published an open letter about the ECT so called modernization process.

More than 300 members of the European Parliament and EU national parliaments from 20 EU member states called EU countries to withdraw from the ECT if protection of foreign investment in fossil fuels is not removed from the Treaty.

Generation Climate Europe has also sent a letter - which has been signed by almost 20 youth-led organizations, representing 30 million young Europeans - to the 27 governments, asking them to withdraw from the ECT and vote amendment 143 of the Climate law.

Through the Institutional Investors Group on Climate Change, investors across 16 countries and representing over 35 trillions € in assets called on members of the EU Council to support the end of fossil investment protection as stated by the European Parliament in the EU Climate Law.

The European Renewables Energy Federation joined the ask for the EU to withdraw from the Energy Charter Treaty, declaring the ECT protects fossil fuel investments and impedes the objectives of the Green Deal and the Paris Agreement targets.
