This submission is presented before the European Court of Human Rights by a group of human rights organizations and academics who have intervened in the first climate change case at the Court. The submission shows that justice must not stop at borders and emphasises the need for climate change to address the greater risks faced by children. The submission provides legal arguments to the Court to show that international law requires states to not harm, and to not allow companies within their jurisdiction to harm, the human rights of people outside their borders.
