 Just before the case went to trial, Hawaii DOT and the youth plaintiffs reached a landmark settlement agreement that puts the state on a new course to zero-carbon transportation. Joanna Ziegler is a staff attorney with Our Children's Trust, which represented the youth plaintiffs, and she joins me now to discuss. Joanna, welcome to Living on Earth. Thank you. Thanks for having me. Joanna, why is this settlement agreement considered sort of first of its kind? What's so new or revolutionary about it?
