2. Class Project: Carbon Footprint of Danforth Campus Objectives: • Develop and Apply Carbon Emission Estimation Model • Estimate Carbon Footprint of Danforth Campus • Compare the Estimates to Other College Campuses

3. Washington University Carbon Footprint Heating On Campus Energy Use Carbon Impact Cooling Appliances Commuting Transportation Carbon Impact Air Travel University Fleet Students Faculty/Staff The impact on carbon arises from on-campus energy use and from transportation

4. Danforth Campus Population • From 1990-2005 the Campus population has fluctuated between 14-16,000 people • Students account for 80 percent of the population on campus

5. University Expenditures and Building Area 60% increase 70% increase During the same time period, the building area (sq ft) has increased by 60 percent. Expenditures Include: Research, Academic, Student Support, O/M of Physical Plant Between 1990-2005, the expenditures increased by 70%

6. Danforth Campus Electric Energy and Fuel Consumption • Fuel used on campus for heating and hot water: coal, oil and natural gas. • In 1993, the University made several upgrades: • Switched from coal to natural gas • Switched to electric chillers • Shut off steam plant from May-October hot water Purchased electricity increased 90% between 1990-2005. The total energy for electricity includes losses in the power plant and during transmission.

7. Causality Framework for University Carbon Footprint - Transportation Miles/Person Gal./Mile Carbon/Gal PopulationPeople Transportation Miles Fuel Cons. Gal./yr C Emission Ton C/yr • Overall the transportation carbon emissions have remained roughly at 1990 level

8. Carbon Emission – Danforth Campus • Carbon Emissions have increased almost 60% from 1990 to 2005. • Electricity is the main component of emissions and also drives the emissions trends

9. Total Emission Comparison between Universities • Data from 14 campuses show that the carbon impact is roughly proportional to the campus size. • Our data indicate that WU emissions/area are comparable to the other schools

10. Transportation Emission Comparison between Universities • Transportation carbon emission estimates for ten campuses indicate a relationship to school population • Washington University estimates are uncertain and given as a range based on two calculation methods • Evidently, the WU transportation carbon emissions are also comparable to the other colleges.

11. Class Outline Follows the NAS Report: Our Common Journey…Sustainability Transition (link) • Common Concerns, Differing Emphases • What Is To Be Sustained • What Is To Be Developed • The Links Between • For How Long? • Goals for a Sustainability Transition • Meeting Human Needs (Education, Research) • Preserving Life Support Systems (Climate) • The Transition to Sustainability as Social ( Academic) Learning
