Climate litigation has become a powerful tool for accelerating the fight against climate change. A series of now landmark court rulings in various countries has compelled their governments to intensify efforts to reduce emissions. These court decisions show that the judiciary clearly understands that climate change is directly linked to human rights, and judges are prepared to make full use of their authority to effectively force state institutions to act on climate policy. Influenced by these successes, activists in various parts of the world have already turned to new complaints and lawsuits against states and companies. In short, the fight for climate action has moved from the streets into the courtroom.
