Kevin Gurney, ASU Global Institute of Sustainability

This short video describes the Hestia project - a software tool and data model that provide visualizations of localized CO2 emissions from residential, commercial, and vehicle levels, as well as day versus night comparisons, in the city of Indianapolis.

Video length is 4:47 min.

Teaching Tips

  • If doing a carbon footprint project in class, have students view the video after they have determined their own carbon footprint and then compare and contrast the two types of carbon footprints in terms of use, information conveyed, value etc.
  • This is a powerful tool to identify high-leverage actions to reduce emissions and to help urban planners and citizens understand the impact of their decisions and actions on CO2 emissions.
  • Educator might want to consider viewing the video using link: http://hestia.project.asu.edu/newsroom.shtml where there is a news article or http://hestia.project.asu.edu/uploads/Gurney.ES&T.2012.pdf to support implementing this software/tool.

About the Science

  • Sustainability Scientist Kevin Gurney and fellow researchers developed software models that measure specific greenhouse gas emissions at the city level. Named Hestia after the Greek goddess of the hearth and home, the program uses data from local cities to measure and pinpoint emissions from specific urban infrastructures like individual buildings and roads. This video explains the measuring process step-by-step and compares emissions in Indianapolis during certain times of the day.
  • Comments from expert scientist: The video has a good general introduction to CO2 being a greenhouse gas and what its dominant sources are in an urban center. Visual representation of the CO2 emissions and its diurnal cycle are very clear and instructive. One concern about the video is the validity of the representations in a few years. It was not clear from the video how often the data input is updated.

About the Pedagogy

  • The graphic display of carbon emissions is very effective at demonstrating the different sources of carbon, and their relative intensity, over the span of one day.

Technical Details/Ease of Use

Middle School

Disciplinary Core Ideas: 1

MS-ESS3.D1:Human activities, such as the release of greenhouse gases from burning fossil fuels, are major factors in the current rise in Earth’s mean surface temperature (global warming). Reducing the level of climate change and reducing human vulnerability to whatever climate changes do occur depend on the understanding of climate science, engineering capabilities, and other kinds of knowledge, such as understanding of human behavior and on applying that knowledge wisely in decisions and activities.

High School

Disciplinary Core Ideas: 3

HS-ESS2.D1:The foundation for Earth’s global climate systems is the electromagnetic radiation from the sun, as well as its reflection, absorption, storage, and redistribution among the atmosphere, ocean, and land systems, and this energy’s re-radiation into space.

HS-ESS3.A2:All forms of energy production and other resource extraction have associated economic, social, environmental, and geopolitical costs and risks as well as benefits. New technologies and social regulations can change the balance of these factors.

HS-ESS3.D1:Though the magnitudes of human impacts are greater than they have ever been, so too are human abilities to model, predict, and manage current and future impacts.
