On 6 and 7 October 2026, the President of the Court, Mattias Guyomar, accompanied by the judge elected in respect of Portugal, Ana Maria Guerra Martins, participated in a summit on Judges, climate litigation and human rights in Vatican City, which brought together judges from national superior courts around the world, as well as from international courts.

In his intervention, President Guyomar provided a comparative analysis of the climate-related case-law of the European Court of Human Rights, the International Court of Justice and the Inter-American Court of Human Rights. He noted that the Court had developed its case-law on climate change within a framework of shared responsibility, drawing on scientific, political and judicial consensus, and highlighted the convergence of judicial approaches that has emerged following the 2024 rulings, namely the cases of Verein KlimaSeniorinnen Schweiz and Others v. Switzerland, Duarte Agostinho and Others v. Portugal and 32 Others, and Carême v. France.

He further stressed that climate change and environmental degradation directly affect the enjoyment of human rights, including those of vulnerable groups, and noted that the convergence of judicial approaches around the world demonstrates that this global challenge knows no borders, affects everyone, and requires joint action for the protection of future generations.
