| Summary / Abstract (Note) | We investigate the effect of driving restrictions on traffic speeds and calculate the implied reduction in carbon emissions using empirical evidence from the city of Xi'an in China. We obtain high-frequency road-section-level transportation data from the Didi Chuxing Technology Company and use a regression discontinuity design (RDD) to identify the causal effect of driving restrictions on vehicle cruising speeds by exploiting a policy variation in 2018. We find that the driving restrictions led to an increase in vehicle cruising speeds of up to 15–20% during peak hours, which consequently dramatically reduced carbon emissions. Based on our back-of-the-envelope calculations, carbon emissions from private vehicles could be reduced by 2.2–5.8% thanks to increased fuel efficiency due to less traffic congestion. |
