Many countries have committed to goals of emission reductions outlined by the Paris Agreement. The actions and results seen thus far from national governments have been lackluster notwithstanding their good faith pledges. City governments have taken it upon themselves to pick up where their national governments have failed. A large portion of emissions are due to transportation. Individuals’ daily travel patterns are typically limited to within a relatively local area. As mobility patterns differ between cities, municipalities have a unique role in transitioning to a sustainable society that blanket policies by national governments cannot achieve. This results in a bottom-up approach in achieving national commitments to the Paris Agreement. In order to make effective policies and plans, municipalities should make decisions based on known information. Before reducing emissions, it must be known where and by whom the emissions are being produced. This report uses Uppsala as a case study to explore how GIS can be used to communicate and create an understanding between data scientists and politicians so that mitigation efforts can be evidencebased. The report results in several methods for visualizing personal automobile emissions based on registration data. The report continues in discussing some potential actions that can be taken to addressing the emissions from neighborhoods indicated as large contributors by the visualizations.
