  4. Global/Regional Trend Objectives • National causality trend analysis of carbon emissions of specific world countries • Comparison of the causal commonalities within and among different world regions and the United States • Comprehension of global and regional patterns of carbon dioxide emissions over time for insight into the driving forces of climate change • Quantified causality model of data from 60 world countries and US for future project use

  5. Approach and Methodology CO2 Emissions = Population x GDP/Person x Energy/GDP x CO2/Energy • Population: The total number of people living in a country at a certain point in time. • GDP/Person: Total GDP in a country divided by its population. Indicates the national economic development and prosperity. • Energy/GDP: Total kg oil consumed per unit GDP. Indicator of the energy intensity of a country’s economy. • CO2/Energy: Metric tons of CO2 emitted per kg oil consumed. Measure of the carbon intensity and content of energy consumption.

  6. Causality Factors for Saudi Arabia • Increases in Population and Energy/GDP • Decrease in GDP/Person and CO2/Energy • The Population and Energy/GDP both drive Carbon Emissions up while GDP/Person and CO2/Energy drive it down. • Increase in Population and GDP/Person • Decrease in Energy/GDP and CO2/Energy • Now the forces driving CO2 up are GDP/Person and Population while Energy/GDP and CO2/Energy drove it down.

  7. Causality Factors for South Africa • Transition from population as the driving force to GDP as the driving force • CO2 emissions have decreased because of lowering of population and a lowering of energy per GDP.

  8. Regional Causality: Europe • Convergence to two points of CO2 emissions per capita • Eastern European Countries: decreasing their emissions to get to these points. • Western European countries: remaining relatively the same in their Carbon/Capita emissions.

  9. Regional Causality: South America 975% increase! • Principal Causality Factor: GDP/Person: Economy is responsible for footprint. • GDP/Person: skyrocketing trend from 1960-2005. Shift in economic nature. • Energy/GDP: net decrease over 35 year time period. • CO2/Energy: relative stability,near-zero trend evolution changing fuel type is responsible. • Note the uncanny relativity between causal factor magnitudes in countries. • Slight convergence over time: Evolution from 14-fold to only 3-fold difference!

  10. Regional Causality: Southeast Asia 1732% increase! 1663% Increase!

  11. Regional Causality: United States • Overall US Emissions were driven up by GDP increases, moderated by decreases in Energy/GDP • Southern and Western states experienced a significant emissions • Much more than north • Due to increase in Population • South also had a larger drop in Carbon per Energy, less significant than the population change

  12. Summary and Conclusions • Regional causality frameworks and case studies of countries prove strong socioeconomic and historical dependence of causal factors • No such “master formula” for causality analysis • Intrinsic relationship with economic development • Significance of geographical placement • Parallel of trends and driving factors in the US • Economic development mostly responsible, dampened by lowered energy intensity • Establishment of framework for sustainable future

The chart to the right represents the total carbon emissions from students and faculty. Best guess total: 5627 metric tons of CO2

  44. Emissions Due to a Parking Spot

  45. Summary & Conclusions • Our best estimates for annual transportation footprints are • ~23,000 metric tons of CO2 from student air commute • ~5,500 metric tons of CO2 from faculty and student regional ground commute • ~527 metric tons of CO2 from lighting and ventilation of parking on campus • This is an underestimation of the actual total footprint • The transportation footprint has been and will continue to increase • To reduce the transportation footprint, we recommend the University • Merge fall and thanksgiving break to reduce flight emissions • Try to reduce the number of people that drive to work by themselves

  47. University Carbon Footprint Objectives • The primary objective of this project was to compile GHG data from other Universities to make comparative analysis with respect to Washington University’s place among other schools when it comes to sustainability. • An additional goal of the data analysis is a qualitative subject investigation to see which areas of a GHG inventory Wash U can improve upon or is already succeeding in.

  48. Approach and Methodology • This project began with a review of the previous class’ report, where size data was only available for 12 schools, and transportation data was only available for 19. Their analysis only really compared these two subjects. We expanded to include net GHG emissions, total campus area, purchased electricity and student population. • Tufts, Smith, Lewis and Clark, Wellesley, College of Charleston, Cal St. Polytech, College of William & Mary, and Occidental College were removed due to lack of data. • Arizona State University, Cornell, and Bates were added as they are known to be sustainable schools • Data for most of the schools was available either on their sustainability websites or through the ACUPCC website. The latter providing a nice and unified way of reporting and measuring GHG emissions • The data was tabulated into a Google Doc. work space along with general statistics for each school (area, pop., etc). From this common source of data, we began to analyze the information for trends

  49. Overall GHG Emissions Time Comparison Fig. 1 • Fig.1 This is a time comparison of total GHG emissions, from the 2008 group data to current data. Note that Wash U ranks 3rd amongst the analyzed schools in terms of gross emissions of CO2, despite Wash U’s size compared to other schools. Also noteworthy is the fact that schools are generally trending to emit more GHG than previously evaluated, this is most likely due to many schools expanding their GHG inventories to account for transportation effects. The large disparity between transportation reporting from the 2008 report to this report is likely the cause of the overall increase in emissions seen in this time period. More information on transportation data reporting can be seen in figures 4a and 5b. • Immediately attention grabbing in this figure is Harvard’s dramatic decline since the time of the previous inventory. More information on this is included in figure 5a.

  50. Per Capita Comparison Fig. 2 INCLUDING MED SCHOOL Without Med School Fig. 2 Per Capita Emissions: Gross emissions per number of students. This graph includes results from the most recent GHG Index results from Wash U, including the medical school. Also, there is no 2008 data for Wash U, but rather there is data for Wash U including only the Danforth Campus (not med school). We included both values to show the dramatic impact medical schools can have on overall emissions. For Gross GHG Emissions, all other indices studied included medical schools. Additionally, the student population counts are a total count, including graduate and medical students. We think this graph (including Wash U + med school) is the most accurate indication of per capita emissions, because of the all inclusiveness of using graduate school campuses + graduate and medical school students, where applicable.
