Building and road segment scale fossil fuel CO2 emissions estimation across multiple US cities spanning the 2010-2021 time period

The Hestia Project estimates fossil fuel carbon dioxide (FFCO2) emissions to the scale of buildings, factories, and road segments for whole cities every hour. Recent updates to the Vulcan Project (version 4) are now realized in 3 large urban domains in the US: the LA Megacity, the NE corridor (Washington DC to Baltimore and beyond) and the city of Indianapolis. Here, we present the latest developments in the estimation from these 3 urban areas and apply a series of hypothetical mitigation efforts, demonstrating the enabling features of high space/time resolution urban FFCO2 emissions estimation. Furthermore, we analyze the spatial patterns of emissions and place them in the context of indicators of social and environmental justice.
