The European Court of Human Rights is set to rule on three climate-related cases from France, Switzerland, and Portugal on 9 April.

A notable Swiss case involves elderly women affected by heatwaves, alleging human rights violations by the Swiss government.

Support from Greenpeace and the group Verein KlimaSeniorinnen Schweiz underpins the Swiss case.

The rulings may influence a major case where six Portuguese youth are suing 33 countries for failing to act on climate change, following the 2017 wildfires.

Decisions on these cases could lead to revisions in European climate policies and establish new rights linked to climate stability.
