is book is the result of a great deal of hard work by many people. We rst thank our chapter authors, all of whom
contributed their extraordinary expertise in researching and writing their chapters, a nd bore with us as we went through
several draf ts of their outlines and chapter texts.
Rachel Jean-Baptiste managed the publication process for the Environmental Law Institute (ELI), including super vis-
ing a legion of copy editors, assembling the indexes of recommendations, paying attention to every deta il, and gently but
rmly pestering many people for many thi ngs to get the book done. We are also grateful to the following p eople from ELI
for their contributions and support: Jay Austin, John Pendergrass, and William J. Straub.
is book builds on the Deep Decarbonization Pathways Project (DDPP) of the Sustainable Development Solutions
Network and the Institute for Sustainable Development and International Relations (IDDRI), and in pa rticular on its
United States volumes. We are grateful for DDPP’s collaboration and support. Members of the DDPP team, in particular
James H. Williams, Ryan Jones, Gabe Kwok, David Ismay, and Ben Haley, reviewed each chapter, responded to questions
from authors, and provided invaluable technical input.
Each chapter was peer-reviewed by several people. We thank the following peer reviewers for their invaluable assis-
tance: Daniel Ada mson, David Adelman, Je Alson, Adell Amos, Nicholas Ashford, David Bookbinder, Richard Caper-
ton, Hannah Chang, David Cleaves, Andrew deLask i, Ethan Elkind, Michael Geller, Robert Grey, Emily Hammond,
David Hayes, Michael Hindus, David Hodgkinson, J. Cullen Howe, David Hunter, Mark M. Jae, Robert A. James,
William M. Keyser, Ray Kopp, Dean Korsa k, Jonathan Krones, erese Langer, James N. Levitt, Yael Lifshitz, Janet
McCabe, James Murray, John R. Nolon, Adam Orford, Curtis Probst, Bill Rawson, Arnold Reitze, Natha n Richardson,
Ethan Rogers, Bob Rubin, Noah Sachs, Ja mes Salzman, Et han Shenkman, Steven Silverman, Richard Singleton, Eleanor
Stein, Jerey Steiner, Edward L. Strohbehn, Jr., Gina Warren, and Michael Webber. Additionally, several chapter authors
reviewed and commented on others’ chapters.
L. Margaret Barry, J. Cullen Howe, Cameron Jones, and Nathan Berry helped with cite checking.
Columbia University’s Center for Global Energy Policy contributed funds to defray some logistical expenses for two
workshops of the chapter authors.
Michael Gerrard thanks his colleag ues at Columbia Law School’s Sabin Center for Climate Change Law and at the
University’s Earth Institute for their assistance and support throughout this project, and his faculty assistant, Adesayo
Adetayo, for her cheerful and diligent help. Most importantly, he wants to thank his wonderful family—Barbara, David,
William, Grace, Anya, a nd Amelia—for their love and support, and their tolerance for long hours at the computer screen
or otherwise absent. Amelia arrived as this book was nea ring completion, but she and her generation have the greatest
stakes in the success of the decarbonization eort.
John Dernbach thanks his colleagues at Widener University Commonwealth Law School, and particularly Dean
Christian Johnson, for their support. He also tha nks faculty secretary Jeremy Wingert for his humor and good work.
He continues to be grateful for the friendship and sage advice of Fred Cheever, a contributor to this book, who died sud-
denly in the middle of this project. John’s wife, Kathy, has been extraordinarily patient and supportive, even though this
project involved many late nights and long weekends, and a good deal more time and eort t han anticipated. Daughters
Becky and Tess and son-in-law Ethan have also been supportive. In the early stages of their careers, they remind us why
we started this book project in the rst place.
