Hestia - the system for estimating air emissions

Experts at Arizona State University (USA) have launched a new software system capable of estimating greenhouse gas emissions in an urban area, on roads and buildings.

The Hestia system can create a map showing where the most carbon dioxide is released.

With the software system called Hestia , the team collected data from various sources such as reports on local air pollution and the number of vehicles. This data is then combined with the CO ₂ emission system in buildings and some road sections. The result of this process is high resolution maps that clearly identify sources of carbon dioxide emissions. "With Hestia, we can provide cities with a complete 3-dimensional picture describing how the location, location and CO ₂ have been released," - Kevin Gurney, Associate Professor School Life Science, affirmed.

To date, Hestia has been applied in the city of Indianapolis (Indiana) and is being deployed to Los Angeles (California) and Phoenix (Arizona). Experts hope the system will quantify CO ₂ emissions in all major cities across the US, which account for a quarter of global emissions. They believe that the Hestia system can help cities, or countries, to identify the places where investment projects in the energy sector and greenhouse gas mitigation are most effective.
