Due to the need for faster reductions in transport greenhouse-gas emissions, policy makers are increasingly paying attention to the role of reducing mobility demand and shifting towards low carbon transport modes. This paper develops the novel open-source Irish Passenger Transport Emissions and Mobility (IPTEM) model and uses it to calculate passenger transport demand by trip mode, purpose, and distance over the period of 2009 – 2019. The paper quantifies energy consumption and emissions intensities, and for the first time for Ireland, passenger transport occupancy rates.
