This document summarizes key points from two lightening talks about decarbonizing transport in Latin America. The first talk discusses how transit reforms aimed at promoting public transport in Latin American cities have often reduced transit ridership by 9-12% on average due to higher costs and lower frequency. The second talk examines ride-hailing apps and finds through simulations that they are very unlikely to reduce vehicle kilometers traveled and likely increase it by taking passengers from more sustainable modes. Both findings suggest the need to rethink current approaches to transport reforms and policies governing ride-hailing apps to better promote sustainability goals.
