Presentation Title: Hestia: High resolution quantification of fossil fuel CO2 emissions for cities: From science to policy



Quantification of fossil fuel CO2 emissions from the 'bottom-up' is a critical element in plans for a global carbon monitoring system (CMS). The space/time explicit emissions data products emerging from this must also have great utility in decisionmaking, and can act as both verification and guidance to greenhouse gas (GHG) emissions mitigation. The Hestia Project has accomplished high-resolution (e.g., building and road link-specific, hourly) quantification of fossil fuel CO2 emissions for entire urban domains. Data products have been built for the cities of Indianapolis, Salt Lake City and Los Angeles, with work ongoing in Phoenix and Washington DC. This bottom-up quantification is often part of scientific programs (e.g., INFLUX, Megacities Carbon), aimed at a convergent top-down/bottom-up assessment of GHG emissions.

Policy/Practice Implications of Research

  • Cities see this information as a communications tool; they are also concerned about continuity and long-term engagement in collecting and utilizing this data.
