Modelling Transport Energy Demand and Emissions: Development of a Global Passenger Transport Model Coupled with Computable General Equilibrium Model

Transport accounted for around 23% of carbon emissions in 2013, which cannot be ignored in terms of global greenhouse gas emissions and climate change. With levels of urbanization and motorization increasing rapidly worldwide, carbon emitted in the transport sector, especially passenger traffic, is projected to keep growing. Without the implementation of aggressive and sustained policy interventions, transport-related emissions could increase at a faster rate than emissions from the energy end-use sectors, with the potential to double by 2050. Because the continuing growth in traffic activities could outweigh all mitigation measures unless transport emissions can be strongly decoupled from gross domestic product (GDP) growth, decarbonizing the transport sector will be more challenging than for other sectors.
