Study on the Energy Demand and Environmental Emissions of Urban Transport—A Case Study of Beijing

Based on LEAP model framework, the Beijing urban passenger transport-energy-environment model was established. Then, the changes in trends of energy demand and conventional air pollution gases and environmental emissions of greenhouse gases in different policy scenarios of Beijing were calculated in 2020. It points out that under the premise of Beijing's increasing demand for urban passenger transport, vigorously developing public transport, especially the rail transport, and restricting the upward development trend of private cars are imperative, while improving energy structure of the end-uses will play an important role in reducing energy demand and slowing the pressure on air quality.
