As we begin considering the judicial nominations President Biden will make and how they could impact decisions about environmental law and climate change, it is worth taking a moment to reflect on the late Justice Ruth Bader Ginsburg's environmental legacy and the indelible mark she left on the field. Although Ginsburg was known primarily for her devotion to advancing gender parity and social equality, she also played a critical role in many significant environmental decisions. Despite the fact that many viewed Ginsburg as a liberal, she actually had a pro-business reputation (which is one of the reasons she was so easily confirmed by a vote of 96-3). While she retained this reputation throughout her career as a justice, she approached environmental law in a nuanced way, often prioritizing the environment when interpreting the laws or regulations before the court. Ginsburg's environmental jurisprudence on the Clean Air Act, Clean Water Act, and the nation's hazardous waste cleanup laws struck a fascinating balance between the practical and the idealistic.
