Managing and reducing our carbon
footprint
• Modeling and simulation
      – LandScan USA
      – Behavior observation over
        large spatial and temporal
        scales

Project Objectives

• Prove or disprove proposed hypothesis
    – 80% of Americans work in the same county they live in or an
      adjacent county


• Determine the number of links and nodes
    – By county and surrounding counties


• Observe all if any patterns between workers and links
  and nodes


• Relate findings to carbon emissions

    – Model Builder
    – Writing scripts
• LandScan USA
    – Worker commute
      model
    – Links and nodes
