As the most-used building material on the planet and one of the world’s largest industrial contributors to global warming, concrete has long been a target for reinvention. Stanford scientists say replacing one of concrete’s main ingredients with volcanic rock could slash carbon emissions from manufacture of the material by nearly two-thirds.

In a Q&A, Stanford economists describe what the social cost of carbon is, how it is calculated and used in policymaking, and how it relates to environmental justice.

Disruptions from sea level rise and coastal flooding events have significant indirect impacts on urban traffic networks and road safety.

April 2021 saw a 20-year high in the number of people stopped at the U.S./Mexico border, and President Joe Biden recently raised the cap on annual refugee admissions. Stanford researchers discuss how climate change’s effect on migration will change, how we can prepare for the impacts and what kind of policies could help alleviate the issue.
