3 Megawatts of Solar Photovoltaic (PV) Capacity

Harvard has installed 3 megawatts of solar panel capacity on campus, the equivalent of 600 home installations, as well as 0.5 MW of installed storage.

2M gallons of water saved

thanks to FAS with water conservation at Laboratory for Integrated Science and Engineering (LISE). The Center for Nanoscale Systems at FAS is retrofitting their systems with projected savings of 2,036,945 gallons per year, equal to ~3 Olympic-size swimming pools.

18.5% decrease in food-related carbon impacts

The shift toward plant-based foods as part of the Coolfood Pledge reduced GHG emissions per plate by 18.5% since 2019. Harvard remains on track to meet the Coolfood 2030 goal of a 38% reduction in per-plate emissions.

~220K lbs. CO2 emissions averted due to EV buses

Harvard’s electric shuttle buses are averting GHG emissions of ~220,500 pounds of CO2 annually. Since the electric shuttles came online in 2021, Harvard has purchased 10+ new EVs, including mail trucks, box trucks, vans, parking vehicles, and utility vehicles.

From Moose to Cattle? Exercising Indigenous Sovereignty in Climate Adaptation Projects

In my new book project, “Contested Icescapes, Land, Politics, and Change on an Arctic Agricultural Frontier,” I explore how marginal Arctic land is being imagined as a new frontier for agriculture under climate change, and what the implications are for rural and Indigenous lands, livelihoods, and governance. In this talk, I will discuss a chapter of the book that examines the political history of agriculture in the Northwest Territories, Canada, and its development alongside recent climate crises in the territory. Drawing on ethnographic research between 2021-3, I will discuss how Sambaa K’e First Nation and Ka’a’gee Tu First Nation are transforming agriculture from a settler-colonial tool of assimilation into an exercise of Indigenous sovereignty. How do these Dehcho First Nations communities make meaning of and assert authority over colonial projects? And what are the possibilities of climate adaptation more broadly, if we recognize Indigenous sovereignty in syncretic land use practices?

Climate, Environment, and the Transition to Late Antiquity: Roman Government’s Response to Climate Disasters and Agricultural Resilience in Roman Egypt

Sabine R. Huebner is a professor of ancient history at the University of Basel in Switzerland whose project at Harvard Radcliffe Institute aims to craft a groundbreaking monograph on third-century Roman Egypt, exploring the dynamic interplay of climatic shifts, political upheavals, and socioeconomic transformations during a pivotal era. Drawing on a rich tapestry of sources—including literary works, papyri, numismatics, epigraphy, and a variety of paleoenvironmental proxies—this ambitious study seeks to unveil new insights into the complexities of this transitional period in one of the Roman Empire’s critical regions.
