  1. From Carnegie Mellon to Kyoto: How Far Can We Go?

  2. Project Courses at Carnegie Mellon Involve real-world, unstructured problems involving technology and public policy. Provide students with leadership experience in problem-solving environments. Require a multi-disciplinary, team-oriented approach. Department of Engineering & Public Policy Department of Social & Decision Sciences H. John Heinz III School of Management & Public Policy Managed by students and monitored by faculty advisors. Assisted by a review panel of campus decision makers, specialists, and industry experts.

  4. The Environmental Impacts of Greenhouse Gases (GHGs) GHG emissions have been cited as a cause of global climate change, causing sea level rises, changes in weather patterns, and health effects. GHGs include carbon dioxide (CO 2 ), methane (CH 4 ), nitrous oxide (N 2 O), and chlorofluorocarbons (CFCs), among others. CO 2 is by far the dominant GHG. Emissions of CO 2 are primarily the result of the burning of fossil fuels, such as coal, natural gas, and transportation fuels.

  5. The Kyoto Protocol The Kyoto Protocol is an international treaty aimed at reducing global GHG emissions in industrialized and developing nations under the 1997 U.N. Framework Convention on Climate Change (UNFCCC). The Kyoto Protocol would limit U.S emissions of GHGs to 7% below 1990 baseline levels by the period 2008-2012, as shown below: projected levels w/o initiatives past data ? % GHG emissions 7 % projected levels w/ initiatives reduction target level reduction time 1990 2001 2010

  6. Project Motivations The United States has chosen not to ratify the treaty, arguing that it is not economically feasible, among other things. However, other nations are pursuing ratification. A growing number of large corporations (e.g. BP Amoco, AEP) are independently pursuing GHG emissions reductions. Can Carnegie Mellon, as part of its environmental initiative, meet the Kyoto Protocol’s targets? If so, how? At what cost? If not, why? How far can we go?

  7. Project Objective Determine the feasibility of reducing greenhouse gas (GHG) emissions associated with Carnegie Mellon University in the context of the Kyoto Protocol. Process: Analyze Carnegie Mellon’s energy consumption and associated GHG emissions. Estimate potential progress toward Kyoto goals. Evaluate possible reduction strategies. Recommend best strategies. Provide other institutions considering voluntary commitment with potentially useful methodologies.

  9. Presentation Outline Carnegie Mellon Energy Consumption and GHG Emissions: A Closer Look Where is Carnegie Mellon’s energy being used? What are our GHG emissions? Kyoto obligations? Behavioral Options to Reduce Energy Demand What can we do to affect the campus community’s behavior in order to decrease energy consumption? Technology Options to Increase Energy Efficiency What can we do to increase the energy efficiency of campus systems and devices? Supply-Side Options to Reduce GHG Emissions Can we purchase “cleaner” energy from suppliers? Can we produce our own energy on campus? Policy Evaluations and Recommendations Who makes the decisions, how are they made, and how can we influence them? What are our final recommendations? Questions & Answers
