Preservation is Climate Action

For decades, preservationists have rightly declared, “the greenest building is the one that is already built.”

The quote is attributed to Carl Elefante, FAIA, former president of the American Institute of Architects. As the planet continues to warm and the models become more dire it is incumbent on historic preservation practitioners to take leading roles in demonstrating and proving that one of the most important steps we can make is to decarbonize the built environment. Old buildings are the greenest buildings out there, but they can be greener and together we can learn more and test new ideas.

In October 2024, 1772 convened a Climate Summit in New Orleans as an affiliate event at the National Trust for Historic Preservation’s PastForward Conference. Most of the materials on this page were shared at that convening, but we will continue enriching this page as a resource.

2024 Advancing Preservation: Climate action Summit

Speakers

  • Setting the context for climate action in the preservation movement in The Relevancy Project.

    Over her 12-year tenure as President & CEO, Bonnie McDonald has led Landmarks Illinois to become a statewide and national voice for relevant change at this inflection point for the preservation movement. Bonnie’s transformative leadership has led Landmarks Illinois to focus on people and their vital connection to place, and to develop collaborative solutions addressing community concerns like climate change, affordable housing and lack of access to capital. Her policy work to incent preservation has led to over $6B in investment in existing buildings and over 30K new jobs created. The James Marston Fitch Charitable Foundation awarded Bonnie its 2020 Mid-Career Fellowship to inform, inspire and support preservation’s evolution through The Relevancy Project, a four-year interview and research initiative culminating in “The Relevancy Guidebook: How We Can Transform the Future of Preservation,” published in November 2023 by Landmarks Illinois. She has since published several articles elaborating on the book’s essays and is a frequent keynote speaker on the topic of enhancing preservation’s relevance. She chaired the board of the National Preservation Partners Network, co-chaired the Chicago Monuments Project Advisory Committee, a two-year truth and racial reckoning process around the city’s problematic artworks, and is an appointee to the State of Illinois Route 66 Centennial Commission. Bonnie serves on task forces for the American Planning Association and the National Council on Public History. In 2022, AIA Chicago honored Bonnie and Landmarks Illinois with its Distinguished Service Award. She holds a master’s degree in City and Regional Planning - Historic Preservation Planning from Cornell University.

  • Overview of the Trust’s work in climate action

    Carol Quillen is the 10th President and Chief Executive Officer of the National Trust for Historic Preservation.

    As the 18th president of Davidson College (2011-2022), she sought to honor the institution’s abiding values—integrity, humane instincts, creativity, discipline, leadership, and service— within our rapidly evolving, increasingly interconnected world. To that end, she helped the campus define a vision founded on ensuring access and affordability, reimagining the liberal arts for today, and equipping graduates to have disproportionate impact for good. Carol also strengthened the college’s commitment to meeting 100 percent of demonstrated financial need for all students with no packaged loans.

    Nationally, Carol is a founding member of the American Talent Initiative (ATI), a consortium that aims to graduate annually 50,000 additional low- and moderate-income students from the nation’s top colleges and universities.

    Leadership for Carol means creating a context where communities can make desired or necessary changes to become more just, more humane, and better equipped to fulfill their shared aims. With her guidance, Davidson built on a liberal arts philosophy to develop a three-pronged model for education that serves the aspirations of a broadly diverse, very talented student body who live within a complex global society. The college’s students cultivate core capacities, like empathy, humane instincts, self-awareness, and intellectual humility; they learn transferable skills, such as creative problem-solving, quantitative analysis, cross-cultural collaboration and effective communication; and they develop technical expertise in their chosen fields, from computer science to art to public health. Combined with local and global experiential learning opportunities such as internships, international study, entrepreneurial projects, and community engagement, students graduate ready to lead meaningful, impactful lives.

    Realizing this vision required a flexible and inclusive organization, Carol restructured and diversified the college’s leadership team, supported a reorganization of the board, developed an agile strategic framework to guide resource allocation, and built partnerships with organizations whose aspirations align with those of Davidson.In this work, she relied on Davidson’s longstanding commitment to both community and good stewardship.

    Beyond Davidson, Carol has advocated for educational equity, institutional accountability, freedom of inquiry, honesty about our history, and the value of the liberal arts. Among other roles, she co-chaired, with General Robert Caslen, the NCAA’s Commission to Combat Campus Sexual Violence and she served on President Obama’s Advisory Council on Financial Capability for Young Americans. She has spoken at numerous venues, including the Aspen Ideas Festival, edX Global Forum, and the Milken Global Conference. She has served on the boards of the Kinkaid School (Houston, Texas), American Council on Education (Washington, D.C.), the Levine Museum of the New South (Charlotte, North Carolina), and Credential Engine, a national organization that enables “credential transparency” in the post-secondary educational sector.

    In 2019, Princeton awarded Carol the James Madison medal, given in recognition of an alumnus/a’s distinguished career advancing the cause of graduate education or record of outstanding public service.

    Carol grew up in historic New Castle, Delaware and attended Wilmington Friends School. She earned a B.A. in American history from the University of Chicago, graduating Phi Beta Kappa with special and general honors, and a Ph.D. in European history from Princeton University. She then joined the History Department at Rice University, serving there on the faculty, as the founding director of the Boniuk Center (now the Boniuk Institute for Religious Tolerance), and as a vice provost and vice president before she was named president of Davidson.

    She has received numerous academic awards, including the Amoco, Brown, Salgo and Sarofim teaching awards (at Rice) and earned fellowships from the Mellon Foundation, the Whiting Foundation, the Fulbright Foundation and Villa I Tatti, Harvard’s Center for Renaissance Studies in Florence, Italy. Carol is the author of two books and many articles. Her writings have appeared in Forbes, The Wall Street Journal, The Hill, Huffington Post, The Hechinger Report, The Washington Post and The New York Times.
