  1. North Carolina State UniversityCarbon Emissions Inventory June 10, 2008 Jeff Hightower Facilities Operations

  2. American College & UniversityPresidents Climate Commitment • NC State University signed the ACUPCC in 2008 • Within one year complete a comprehensive inventory of GHG emissions which will be updated every other year • Within two years develop an action plan to reduce GHG emissions

  3. American College & UniversityPresidents Climate Commitment • University is to adopt two actions to reduce GHG while developing an action plan • NCSU has adopted the following: • U.S Green Building Council’s LEED Silver Standard or equivalent • U.S. EPA’s ENERGY STAR Partner • Provide access to public transportation

  4. Other GHG/Energy Initiatives • The State of NC will require Title V Permit holders with point sources to submit their GHG emissions for CY 2008 • Senate Bill 668 – 20% reduction of energy by 2010 and 30% reduction of energy by 2015 • The United States Congress is debating on Federal legislation to require facilities that are sources of GHGs to report their emissions and provide caps or reductions. (Lieberman-Warner Act, McCain-Lieberman Act, Sanders/Boxer Act, and Bingaman Act)

  5. GHG Inventory • Fuel consumption records • Purchased electricity • Emissions factors (Climate Registry, EPA AP-42, etc.) • Global Warming Potential (GWP) expressed as CO2 equivalents • GHG Protocol • Organizational boundaries (policy decisions) • Operational boundaries (financial control) • Scopes

  6. Types of Calculation Methods Global Warming Potentials: CO2 : 1 CH4 : 21 N2O : 310 From EPA’s Climate Registry General Reporting Protocol Ver. 1.1

  7. Example Emissions Calculations Calculation for fuel oil: Calculation for natural gas: Average carbon content: Natural gas: 14.47 kg C/MMBtu Distillate (No. 2) fuel oil: 19.95 kg C/MMBtu Residual (No. 6) fuel oil: 21.49 kg C/MMBtu From U.S. EPA, Inventory of Greenhouse Gas Emissions and Sinks: 1990-2005 (2007), and EPA’s Climate Registry General Reporting Protocol Ver. 1.1

  8. Example of Carbon Dioxide Emissions from Various Fuels

  9. CO2 CH4 N2O PFCs HFCs SF6 GHG Inventory Boundaries Scope 2 Indirect Scope 1 Direct Scope 3 Indirect NCSU Owned Vehicles Purchased Energy Waste Disposal, Commuting, Travel, Product Use Fuel Consumption Modified Version from New Zealand Business Council for Sustainable Development, 2002

  10. NCSU Carbon Inventory Structure

  11. NCSU Proposed Combined Heat and Power (CHP) Project • Add two 5.5 MW combustion turbines with heat recovery steam generators (CT-HRSG) • Fuel conversion from residual (No. 6) fuel oil to distillate (No. 2) fuel oil and natural gas From 2006 IPCC Guidelines for National Greenhouse Gas Inventories

  12. Questions and Comments
