Quantifying carbon dioxide emissions like never before.

The Hestia Project™ will revolutionize how the world approaches and interacts with the climate change problem. The Hestia system quantifies all fossil fuel CO2 emissions at the scale of buildings, streets and factories. Hestia can provide stakeholders an unprecedented opportunity to design and implement carbon management strategies, verify emissions reductions, strengthen and support basic research in climate prediction and carbon cycle science, and allow the public, decisionmakers, scientists and industry access to detailed space-time information on fossil/industrial energy consumption and CO2 emissions. All this will be done via an intuitive, interactive, photorealistic, three-dimensional visualization of an urban area. And work is ongoing to embed these systems into formal urban planning models and processes.

In short, Hestia will quantify, simulate and visualize
the metabolism of greenhouse gas emitting activity down to the building and street level


Work is ongoing to dramatically update all existing Hestia cities and add new cities to the collection. Please check back Summer 2018 to see the progress.


More About the Hestia Project™

The Hestia Project™ builds on a NASA/DOE/NSF-funded project called Vulcan*. Vulcan has quantified fossil fuel CO2 in the United States at sub-county spatial resolution and hourly temporal resolution for the year 2002 with considerable sectoral/fuel/process detail.

The First Hestia City: Indianapolis, Indiana

With funding from the Purdue Showalter Trust, Knauf Insulation and most recently from the National Institute for Standards and Technology (in the context of the INFLUX experiment), a case study of Indianapolis (and surrounding counties) has been accomplished. The final visualization, currently under construction (example in the figure below), will aim towards a dynamic environment where users can zoom and pan over portions of the city, imaging sub portions of carbon dioxide emissions by sector, sub-sector and area. The Indianapolis case forms the basis of our recent publication and outreach video along with four excellent papers led by INFLUX collagues: Obie Cambaliza with a paper in Elementa on source apportoinment of methane, and another paper on uncertainties on aircraft mass-balance approaches., Jocelyn Turnbull using 14C to isolate source sectors in Indianapolis, and last but not least, Thomas Lauvuax who has a excellent paper on wintertime inversion of atmospheric CO2 for unban fluxes.. Graduate student Ryan Anderson has performed a policy analysis for the City of Indianapolis using the Hestia results. A short description can be found here.

The Second Hestia City: Los Angeles, California

In collaboration with the Jet Propulsion Laboratory/CalTech, we have completed a version 2.0 of the Hestia data product for the Los Angeles Basin. This effort is a key component of a Carbon Monitoring System for a Megacity domain. The Hestia data product in the LA Basin covers all five counties touching the Basin (Los Angeles, Orange, Ventura, Riverside, and San Bernardino). The results are available to research colleagues but a public release may occur later in 2016/2017.

The Third Hestia city: Salt Lake City, Utah

As part of a collaboration with colleagues at the University of Utah, we have built a data product for Salt Lake County. Our University of Utah colleagues will be incorporating criteria air pollutants into Hestia for use in Salt Lake Valley, where air quality issues are of particular importance. Go here for media coverage of the release event.

The Fourth Hestia City: Baltimore, MD

With continued funding from the National Institute for Standards and Technology (NIST), we have completed the first East Coast Hestia City: Baltimore, MD. Shapefiles and gridded output for Baltimore City can be retrieved by contacting Dr. Kevin Robert Gurney. A paper, highlighting the results, is in preparation.
