1 University of Wisconsin Platteville Sustainability Goal Setting Workshop 30 November 2010

2 Higher Education & Sustainability: An Introduction to GHG Inventories & Climate Action Planning Affiliated Engineers, Inc UW- Platteville November 30, 2010

3 Higher Ed Concerns / Constraints Improve / maintain fiscal health while addressing reputational goals Constrained financial environment (CAPEX and OPEX) Rising energy costs and volatility Transparency in regards to total cost of ownership Prioritizing renewal needs Consistent decision quality is hampered by the lack of uniform information across the institution

4 American College and University Presidential Climate Commitment Commitment by over 600 higher educational institutions to make a substantial reduction of their carbon emissions Required to do a greenhouse gas inventory and a climate action plan colleges and universities must exercise leadership in their communities and throughout society

5 Carbon Inventory What is it? Standardized accounting for an institution s carbon emissions Examines all institutional-related carbon impacts Carbon equivalents: CO 2 Methane Nitrous Oxides Sulfur Oxides Refrigerants Measured in Metric Ton of Carbon Equivalent (MT CO 2 e)

6 Three Scopes of a GHG Inventory Scope 1 : directly occurring emissions from sources that are owned or controlled by the institution: Natural gas Refrigerants Fleet vehicle fuel Scope 2 : indirect emissions generated in the production of electricity consumed by the institution: Electricity Purchased chilled water Scope 3 : other indirect emissions that are a consequence of the activities of the institution, but occur from sources not owned or controlled by the institution: Business- related Air travel Commuting Paper/Waste Consumption Source: World Resources Institute, New Zealand Business Council for Sustainable Development,

7 Scientific Consensus IPCC Climate Stabilization Level Catgory Concentration at Stabilization CO 2 2 CO 2 - equivalent 3 IPCC Climate Stabilization Scenarios 1 Peaking Year for CO2 Emissions in 2050 (% of 2000) Change in Global Average Temperature 4 Average Sea Level Rise 5 (meters) (ppm) (ppm) CO2 Emissions ( o C) I to II to III to IV to V to VI to Notes to Exhibit 2 IPCC is the Intergovernmental Panel on Climate Change. Information is taken from the "Climate Change 2007: Synthesis Report", 1 Table 5.1, page = 379 ppm 3 Includes greenhouse gases (GHGs) and aerosols; 2005 = 375 ppm 4 Above pre-industrial at equilibrium 5 Above pre-industrial at equilibrium from thermal expansion only

8 Data Collection Utility Data at least one year Refrigerant Purchases Fleet fuel purchases Commuting by Students, Faculty and Staff Business Related Air Travel Waste

9 CO2 and CO2e

10 Snapshot of Emissions

11 What does 1000 Metric Tons CO 2 e really mean? ~100,000 ~23,000 ~38,000 gallons of gasoline consumed tree seedlings grown for 10 yrs propane cylinders used for home barbeques 110 homes electricity usage for one year Source:

12 Working with an Abatement Hierarchy

13 What s a Climate Action Plan? A comprehensive plan for an institution to become climate neutral, which will include a target date for achieving climate neutrality as soon as possible. Interim targets for goals and actions that will lead to climate neutrality Actions to make climate neutrality and sustainability a part of the curriculum and other educational experience for all students Actions to expand research or other efforts necessary to achieve climate neutrality Mechanisms for tracking progress on goals and actions
