In countries across Africa and Latin America, old used cars from places like the U.S. and Europe provide vital access to transportation to people who would otherwise be unable to afford their own vehicles. While this process extends the lives of these cars, the practice is not without problems, in particular with regards to pollution and passenger safety. We speak with two researchers about why richer countries export used cars, what impacts they have in developing nations and whether import restrictions are effectively stemming the rise in pollution and accidents caused by this practice.

Featuring Festival Godwin Boateng, Postdoctoral Research Fellow at the Centre for Sustainable Urban Development at The Earth Institute at Columbia University in the US, and Paul Bledsoe, Professional Lecturer at American University in the US.
