Vulcan-UrbanML: Estimated fossil fuel CO2 emissions from global cities

Vulcan-UrbanML is a machine-learning framework developed to estimate global urban fossil-fuel CO₂ (FFCO₂) emissions using relationships learned from a multiple input datasets trained on the U.S. Vulcan emissions dataset. The resulting emission estimates provide a consistent set of annual urban FFCO₂ emissions across multiple urban boundary definitions and a comprehensive list of global cities.
