Jennifer Dunn, professor of chemical engineering at Northwestern University, joins Thinking on Paper to explain how lithium and copper mining affect water, ecosystems, local communities and the wider energy transition.

Lithium and copper are essential to electric vehicles, grid storage, renewable energy, drones and data centres. But the environmental consequences of extracting these minerals vary sharply depending on the mine, location, technology and supply chain.

Life cycle assessment offers a way to compare those impacts across different forms of production, from lithium brines and hard-rock mining to copper extraction, refining and recycling.

In this episode, we discuss:

• The environmental impact of lithium mining

• How lithium brine mining compares with hard-rock lithium mining

• Why copper demand is rising

• How mining affects water use and local water stress

• The risks of pollution, biodiversity loss and mining waste

• How life cycle assessment compares mines and supply chains

• Why local conditions matter more than global averages

• The role of mine permitting in the energy transition

• Whether recycling can reduce demand for new mining

• How battery supply chains shift environmental costs between regions

• What responsible critical-mineral production should look like

Jennifer explains why no single measure can capture the full impact of a mine. Carbon emissions matter, but so do water availability, land use, waste, local ecology and the distribution of costs and benefits.

This conversation examines whether clean energy can scale without transferring environmental harm from fossil-fuel systems to the communities that supply lithium, copper and other critical minerals.
