KlimaSeniorinnen: lessons from the Swiss senior women's case for future climate litigation

Abstract

As older women are particularly vulnerable to climate change impacts, a group of senior women in Switzerland founded the association KlimaSeniorinnen Schweiz (Senior Women for Climate Protection Switzerland) in order to fight for ambitious climate action by legally challenging the Swiss government's inadequate climate policies and mitigation measures. The KlimaSeniorinnen filed a legal request with the authorities, claiming that the Swiss authorities are failing to fulfil their duty to protect them as required by the Swiss Constitution and by the European Convention on Human Rights. This article provides a detailed analysis of the KlimaSeniorinnen case within the context of climate litigation worldwide. It argues that the case's human rights arguments, which are grounded in climate science, the United Nations Framework Convention on Climate Change (UNFCCC), the Paris Agreement, environmental principles and international law, are generally transferable to almost any country. Therefore, vulnerable individuals and groups can learn from the KlimaSeniorinnen litigation that there are strong legal grounds to bring human-rights-based climate lawsuits against governments and thus governments should expect more litigation if their climate actions or omissions contravene international law and violate constitutional principles.
