The 29th March 2023 has the potential to go down in history as a milestone in the global fight against the ever-more imminent climate crisis. For the first time ever, the European Court of Human Rights (ECtHR) in Strasbourg is holding a public hearing to assess the extent to which a nation such as Switzerland must reduce its greenhouse gas emissions more stringently to protect the human rights of its own population. The reason for this is the complaint with which the Senior Women for Climate Protection and four individual plaintiffs from Switzerland have now reached the ECtHR.
