On April 25, 2019, the Environmental Law Institute (ELI) held an event to provide an overview of their latest publication, a book titled Legal Pathways to Deep Decarbonization in the United States. Providing an overview of the book, a few of the authors were part of a panel discussion opened by William K. Reilly, former EPA Administrator under President George H. W. Bush. In his opening remarks, Mr. Reilly emphasized the potential existing with politics to change culture to achieve low-carbon emissions in the near future. Following Mr. Reilly, Commonwealth Professor of Environmental Law and Sustainability Director at Widener University, John C. Dernbach, started the panel discussion by providing an overview of the contents of the book. According to Professor Dernbach, deep decarbonization is defined as achieving at least 80 percent GHG emissions through deep cuts by 2050. The book therefore contains chapters on federal, state, and tribal legal tools that are available to decarbonize the U.S. In the book, the authors present twelve types of legal tools available; some that are regulatory tools, and some that are not. Types of legal tools include, research and development (R&D), market leveraging approaches, removal of incentives for fossil fuels, and infrastructure development, among others. During the event, other authors and co-authors spoke about specific chapters of the book, stating that they were almost certain that the legal tools available would create economic, social, and environmental security. Unfortunately, the event was interrupted by a fire alarm in the building. For further information, the book can be found for purchase here.
