The Nature Conservancy (TNC) in Pennsylvania and Delaware today announced that Hayley Book has been elected to its Board of Trustees for a three-year term effective July 1.

Book has extensive experience at the intersection of government affairs and energy policy, serving as a principal consultant leading a consortium of energy and utility companies in navigating the complex policy and regulatory landscape affecting the power sector. She has worked for more than a decade in senior advisory roles at the Pennsylvania Department of Environmental Protection and the state’s Public Utility Commission, where her work focused on policies to advance decarbonization of the power sector including carbon pricing, renewable energy development and finance, and streamlined integration of clean energy into the grid.

“Hayley is a distinguished and accomplished leader in renewable energy and climate policy, and I am delighted to welcome her to our Board of Trustees,” said Lori Brennan, executive director of The Nature Conservancy in Pennsylvania and Delaware. “She will bring a unique perspective and invaluable expertise to our organization as we work together to deploy innovative solutions to our most complex environmental challenges.”

“I am thrilled to join TNC, which values science-based conservation in support of people and nature in Pennsylvania and Delaware,” said Book. “I look forward to building on the great work taking place across our two states in order to ensure healthy lands, waters and cities for future generations.”

Book continued: “Hikes on the Appalachian Trail energize me, as does an appreciation of the solitude and beauty of our natural world. This underpins my value system and serves as the foundation for my children’s as well.”

Book served as a Peace Corps volunteer in Cameroon and holds a B.S. in environmental policy from the University of California at Davis and a Master of Public Administration from the Monterey Institute of International Studies. She regularly volunteers for the Pennsylvania Envirothon and the Ten Million Trees program. She currently serves as a corporate relations advisor for Shell USA, Inc., supporting assets across the northeastern U.S. including energy markets, low-carbon solutions, renewable power and electric vehicles.

In Pennsylvania and Delaware, TNC is leading large-scale conservation programs that protect the lands and waters that are critical to the health and well-being of both people and nature. In Pennsylvania, TNC works to reduce stormwater runoff in cities, protect vital Central Appalachian landscapes like the Kittatinny Ridge and engage farmers in supporting the adoption of conservation practices. TNC’s work in Delaware focuses on building resilience against climate change—including along the state’s vulnerable coastlines—to protect natural habitats and human communities.
