Objectives of Model
What did you group hope to accomplish?
• To further develop and expand on the work of the 2008 class project, as it relates to carbon emission for short and long distance commuting travel.
• To more accurately estimate carbon emissions
• To clarify the impact of each causality node will with possible reduction approaches identified for each.
Why care about this particular part of transportation?
Commuting, both locally and “home for the holidays,” is a significant part of WashU’s carbon footprint, and therefore something that would be beneficial to investigate how to reduce.

Model Methodology
What is the methodology of your approach?• Rely not only on data from previous classes, but also on national
data regarding method of travel.
• Consider student trips during holidays in calculating carbon emissions for Washington University.
• Much of our time was spent improving last year’s model to make it more accessible, and usable in the future.
What do the causality factors mean?

Model Methodology
Include the causality factor calculation
What assumptions did you make? • Used upper and lower bounds for calculations to show uncertainty in
a range
• Students with different parking passes drive to class more than others
• Students that live closer to school make more trips home
• Students that live with in 300 miles fly rather than drive home

Improvements and Next Steps
What do you think could be improved in the course of the rest of this semester?
-Because we were limited on what data we received before the deadline for this project, there are improvements we can make by the end of the semester.
-Upon receiving parking pass data, we can make more accurate estimations regarding commuting.
Forecasting into the future – what are possible scenarios your group thinks should be included?
