AbstractWashington University, following the trend of many other academic institutions,
performed a University-wide carbon emission footprint during the Spring of 2008 for 1990-2007. The carbon footprint was a collaborative effort between university facilities, an outside consultant and Prof. Husar, teaching EECE 449, Sustainable Air Quality. The collaboration was successful because of the excitement the students had about participating in work that was directly applicable to campus and the facilities department’s need for explanations about the cause of GHG emissions. The Sustainable Air Quality class narrowed the scope of the project to the Danforth Campus and focused on three main objectives: (1) develop a carbon footprint causality model; (2) estimate the carbon footprint and (3) compare our estimates to other universities carbon emission estimates. The Danforth campus saw over 50% increase in carbon emission from 1990 with 80% of that due to electricity usage. The class also found that the estimate for carbon emission on the Danforth campus was comparable to other universities that had performed similar footprint analysis. Future work will include using the carbon footprint causality model to explore various methods for carbon emission reduction.

Specific Objectives:
1. Develop and apply carbon emission estimation model
2. Estimate the carbon footprint of Danforth Campus
3. Establish the key causality drivers for the emissions
The focus of this poster is on campus carbon emissions. Further work is still needed for transportation carbon estimates.

Campus as a Living Laboratory• The Sustainable Air Quality class, EECE 449/549
worked in collaboration with Facilities department and a consultant to establish a carbon footprint.
• Using data collected by the consultant, the class with the consultants established the carbon emissions for the Danforth Campus.
• The class contribution was to begin explaining carbon drivers, modeling future through scenarios and comparing our carbon estimate to peer institutions.
• The class experience overall was positive. Students were engaged throughout the entire semester because the activities directly related to their lives.

Method: Causality Model
• Systems approach: linking human activities and their consequences in closed loop• Each component depends on its causal upstream driver – and external forcing• The causal loop can be used as an organizing principle for sustainability analysis

Discussion:
• Carbon emission has increased by 60% from 1990-2005
• Increased building square footage and decreased energy efficiency has led to increased carbon emissions
• By manipulating the energy efficiency or carbon efficiency reductions could be made.
