Supply Chains as Vectors of Inequality

Lithium, a crucial input in the batteries powering electric vehicles, has the potential to save the world from climate change. But even green solutions come at a cost. Mining lithium is environmentally destructive. We therefore confront a dilemma: Is it possible to save the world by harming it in the process?

Having spent over a decade researching mining and oil sectors in Latin America, Thea Riofrancos is a leading voice on resource extraction. In this episode, we discuss her 2025 book Extraction: The Frontiers of Green Capitalism, in which she draws on groundbreaking fieldwork on the global race for lithium. Taking readers from the breathtaking salt flats of Chile’s Atacama Desert to Nevada’s glorious Silver Peak Range to the rolling hills of the Barroso Region of Portugal, the book reveals the social and environmental costs of “critical minerals.” She takes stock of new policy paradigms in the Global South, where governments seek to leverage mineral assets to jumpstart green development. Zooming out from lithium, we also discuss the evolving geopolitics and geoeconomics of energy transition, critical minerals, and green technology supply chains.
