2. 2 National Park Service U.S. Department of the Interior Overview  Lingo: GRCA = Grand Canyon National Park GHG = Greenhouse Gas CAP = Criteria Air Pollutants CFP = Climate Friendly Parks CLIP = Climate Leadership in Parks  Agenda: GHG Accounting Primer GHG Inventory Results Next Steps

3. 3 National Park Service U.S. Department of the Interior GHG Accounting Primer  It’s as easy as A x B = C Activity Data x GHG Emission Factor = GHG Emissions Collect Data Select Methods and Emission Factors  The Climate Leadership in Parks (CLIP) Tool Microsoft Excel-based application that parks use to manage carbon

4. 4 National Park Service U.S. Department of the Interior The most important part Thanks to:  Deirdre Hanners – Grand Canyon National Park  Megan Bloomer – Xanterra South Rim  David Trenchard – DNC Parks & Resorts at Grand Canyon  Rick During – Forever Resorts  Lee Metheny & Andrew Aldaz – Grand Canyon Unified School District  John Pearson – Grand Canyon Association  And all the other folks who answered all our weird questions about arcane numbers throughout the park

5. 5 National Park Service U.S. Department of the Interior GHG Accounting Primer  Greenhouse Gases Carbon Dioxide (CO 2 ), Methane (CH 4 ), Nitrous Oxide (N 2 O), and High Global Warming Potential (GWP) Gases (HFCs, PFCs, SF 6 )  Emission Sources Stationary Fossil Fuel Combustion (Energy) Purchased Electricity (Energy) Mobile Fossil Fuel Combustion (Transportation) Landfilled Solid Waste (Waste) Wastewater Treatment (Waste) Refrigeration and Air Conditioning (Other) Fertilizer Application (Other)  Entities Park Operations, Visitors, Concessioners, etc.

6. 6 National Park Service U.S. Department of the Interior Park Operations GHG Inventory Results  Total Park Operations GHG Emissions = 15,985 MTCO 2 E*  Equivalent to the amount generated by about 1,400 American homes through their annual energy use. *Metric Tons of Carbon Dioxide Equivalent

7. 7 National Park Service U.S. Department of the Interior Park Operations GHG Inventory

8. 8 National Park Service U.S. Department of the Interior Total Park GHG Inventory Results  Total Park GHG Emissions = 55,741 MTCO 2 E  Equivalent to the amount generated by about 10,200 American cars through their annual use.

9. 9 National Park Service U.S. Department of the Interior Total Park GHG Inventory

10. 10 National Park Service U.S. Department of the Interior Data Gaps and Assumptions  Data Gaps Grand Canyon Railway Smaller operations Aircraft Use (35,399 flights)  Assumptions Emergency generator emissions approximated Excluded some activities (i.e., Hermit Road reconstruction, wildland fire, residential)

11. 11 National Park Service U.S. Department of the Interior The Baby in the bath…  Grand Canyon recycled 1,000 tons of waste in 2008  18 kW Solar installation at CVIP donated  Continuing conversions to alternatively fueled vehicles by NPS & concessioners  Reclaimed water use  Existing reduction targets  Green procurement – are our partners ahead of us?

12. 12 National Park Service U.S. Department of the Interior Already in our sights…  35% of our electric use goes to getting water from Indian Garden to the South Rim  56% of our fuel oil for heating goes to a single building (McKee) that is slated for replacement (any day now…)  Our largest propane user (GCVC) already incorporates passive solar features

13. 13 National Park Service U.S. Department of the Interior Next Steps  Keep up the good work!  Prepare Climate Action Plan  Implement Actions, the Green Team  Update Inventory  Monitor Progress  Educate
