Global greenhouse gas emissions continue to climb every year. It is clear that to reduce emissions, new measurement tools which allow us to exactly quantify the source of GHG pollution will play a key role. New tools such as Hestia are revealing detailed information of realtime source of emissions, giving policymakers the information required to create effective greenhouse gas legislation and helping investors to identify where an investment in energy and greenhouse gas savings would have the greatest impact.

The Hestia Project

The Hestia project is a GHG measurement project developed by scientists at the University of Arizona. It uses an array of sensors that track a variety of anthropogenic emission sources combined with municipal data such as tax assessment information along with modeling software to generate a realtime 3D map of precise GHG emission sources in any US city down to the street level.

“Cities have had little information with which to guide reductions in greenhouse gas emissions – and you can’t reduce what you can’t measure,” said Kevin Gurney, an associate professor in ASU’s School of Life Sciences, and senior scientist with the Global Institute of Sustainability. “With Hestia, we can provide cities with a complete, three-dimensional picture of where, when and how carbon dioxide emissions are occurring.”
