R.; Song, Y.; Asefi-Najafabady, S.; Rayner, P. J. Abstract The Fossil Fuel Data Assimilation System (FFDAS) quantifies fossil fuel carbon dioxide (CO2) emissions for the planet at a scale of 10 km hourly for the time period 1997-2012. FFDAS is based on the Kaya identity constrained by multiple ground and space-based observations. Among these are the DMSP nightlights, Landscan population, and the Ventus power plant database. We have recently downscaled the FFDAS version 2.0 to 1 km x 1 km resolution using nighlights. The finer spatial resolution allows for the examination of urban emissions across the planet. We take two approaches to examination of urban FFCO2 emissions. The first, utilizes named administrative boundaries combined with manual GIS identification (supported by LandSat and ISA) to identify the top emitting urban areas of the planet. We also utilize an urban land mask, without governmental boundary identification, to analyze all urban area by country across the planet. We perform multiple regression to identify key drivers and patterns. The results demonstrate the change in urban emissions during the last decade and assess the question of whether urban areas exhibit scaling properties vis a vis FFCO2 emissions.
