Barnard’s Department of Environmental Science was founded 35 years ago. Its origins, however, reach as far back as Barnard’s first year, 1889, when students studied geology, geography, and mineralogy with Columbia University professors. Below we share the history of the department as it grew from one course to a department that is leading innovation in environmental research and education.

The Hits: Several Notable Environmental Science Alumnae

Sally M. Benson '77 studied geology, an ancestor of the Department of Environmental Science. Today, she is a professor of energy resources engineering at Stanford University and director of the Global Climate and Energy Project and the Precourt Institute for Energy, the hub of energy research and education at the university. An internationally recognized groundwater hydrologist and reservoir engineer, Benson is widely regarded as a leading authority on carbon capture and storage, energy systems for a low-carbon future, and emerging energy technologies. She has served as a convening lead author of the Global Energy Assessment, a multinational project that was the first fully integrated assessment that analyzed energy challenges, opportunities and strategies for developing, industrialized and emerging economies.

Annie Leonard '86, executive director of Greenpeace USA, is a graduate of the environmental science department. She is the founder of The Story of Stuff Project, a worldwide movement of more than a million environmental activists who work to educate others on how our production and consumption patterns affect people and impact the planet. The Project was born from a 20-minute online animated movie, narrated by Leonard, about the way we make, use, and throw away all the stuff in our lives; the film has received about 40 million views. She has created a dozen short films shining light on environmental issues.

Rhea Suh '92 majored in environmental science and is now president of the Natural Resources Defense Council (NRDC). Following the receipt of a masters in educational policy and administration, she served as Assistant Secretary at the U.S. Department of Interior, managing national parks, wildlife refuges, public lands and offshore resources along the Outer Continental Shelf. As head of NRDC, Suh leads nearly 500 scientists, attorneys, and policy experts and works with more than two million members and activists to create solutions and enforce laws that preserve clean air and water, open spaces, public lands, and healthy communities.

Tsechu Dolma '14, a double major in Asian and Middle Eastern Cultures and Environmental Policy, is now at Columbia University’s School of International and Public Affairs program (SIPA) and cofounder of the Mountain Resiliency Project. The nonprofit works directly with farmers to help develop sustainable livelihoods by building climate change-resilient communities for social and economic justice. She has received numerous honors and fellowships for her work including a Brower Youth Award for “creating a model for sustainable food security in Upper Mustang, Nepal” and a 2016 Impact Grant, and was named one of Forbes’s 2017 “30 Under 30” for her entrepreneurship.
