This mitigation effect mainly comes from the substitution of highway goods transport with the conventional railway instead of the direct replacement of highway passenger transport with HSRs. These effects translate into an annual reduction of 11.183 million tons of CO 2 equivalent of GHG emissions or 1.33% of GHG emissions in China’s transport sector. These reductions were not seen on ordinary national roads. Using the difference-in-differences method, we show that new HSR routes in China lead to a 20.5 log-point reduction in the number of passenger vehicles and a 15.7 log-point reduction in freight vehicles running on parallel highways. High-speed rail (HSR) is one such example, yet it is unclear how much reduction in road traffic results from new rail routes. Carbon emission reduction in the transportation sector is essential in the global mitigation effort, and a large-scale public transport system has the potential to be an effective instrument.
