Arizona State University researchers have developed a new software system capable of estimating greenhouse gas emissions across entire urban landscapes, all the way down to roads and individual buildings. Until now, scientists quantified carbon dioxide (CO2) emissions at a much broader level. Dubbed "Hestia" after the Greek goddess of the hearth and home, the system combines extensive public database "data-mining" with traffic simulation and building-by-building energy-consumption modeling. Its high-resolution maps clearly identify CO2 emission sources in a way that policy-makers can utilize and the public can understand. Hestia provides a complete, three-dimensional picture of where, when, and how carbon dioxide emissions are occurring.
