In this week’s episode, host Kristin Hayes talks with Luis Sarmiento, a postdoctoral researcher at RFF’s sister institution in Italy, the RFF-CMCC European Institute on Economics and the Environment. Sarmiento recently coauthored a working paper that explores the air pollution impacts of Uber across the United States. The study aims to clarify the environmental consequences of ridesharing companies like Uber. Sarmiento discusses his surprising results and potential areas for future research.
