Short summary

We studied vehicle emissions from ten 3000-meter tunnels on the Tibetan Plateau. Emissions of volatile organic compounds (VOCs) increase with elevation due to the evaporation of fuel oil from low pressure, unlike at lower elevations where tailpipe is predominant. This suggests that specific emission control measures are needed. This research aims to understand emissions at high altitudes and to guide cleaner transport.
