Transport carbon emissions are set to increase by 60 percent in 2050 from 2015 levels, while they should decrease by over two thirds in a below 2°C scenario. A Paris-compliant sustainable mobility system will not be possible without the rail and public transport sectors. Considering the low energy and CO2 intensities of rail transport, shifting passenger and freight activity from more intensive modes such as private cars, trucks and airplanes to rail and public transport is a key strategy for net zero alignment. Investments in railways produce several multiple socioeconomic benefits such as job creation, urban revitalization, cleaner air, among many others that are not always easy to estimate and quantify. In this session, we hear from experts in the industry and in the finance sector on the return on investment in rail to society and how an enabling policy environment can get us there.
