1 Dan Golub 2007 Greater Yellowstone Area Greenhouse Gas

2 Big Picture The Forest Service joined EPA Climate Leaders program in 2007 First federal land management agency to join 7 pilot locations Greater Yellowstone Area (GYA) is the only one that is ecosystem-wide, & the only one completed to date Serves as a model for the rest of the agency Lessons learned from this inventory will be used to inform future inventories Springboard for ecosystem-wide collaborative goal setting & implementation 3 federal agencies in GYA- FS, National Park Service, US Fish & Wildlife Service Part or all of the following Forests were included in the inventory: Bridger-Teton, Beaverhead-Deerlodge, Caribou-Targhee, Custer, Gallatin, Shoshone

3 Big Picture is a baseline for future comparisons Anthropogenic emissions of 3 GHGs carbon dioxide (CO2), Methane (CH4), and nitrous oxide(n2o). No carbon sequestration or storage in the Climate Leaders tool. Similar inventories conducted by other federal land management agencies within GYA. The National Park Service (NPS) conducted a GHG inventory of Yellowstone and Grand Teton National Parks using CLIP (Climate Leadership in Parks). The US Fish and Wildlife Service (USFWS) conducted a GHG inventory of the National Elk Refuge, and Red Rock Lakes National Wildlife Refuge using the Climate Leaders tool.

6 Approach Decide basic inventory parameters - base year, organizational scope, geographic scope, pollutants, etc. Choose an inventory tool to house data and calculate emissions. Survey your organization. What sort of emission sources do we have? What data is impossible to obtain or difficult to get? Send out detailed data request. Patience, persistence, and persuasion.

7 Approach (continued) Implement Quality Assurance/Quality Control protocols. Crunch, check, re-crunch, and re-check numbers. Obtain peer, internal, and external review.

8 GHG Emission Type Direct Emissions by Source Category Source Category Emissions Included in the? Comments Mobile sources Yes Largest single source of emissions in this inventory. Stationary sources Prescribed fire and wildfire suppression Air conditioners, refrigerators, and freezers Fire extinguishers Yes No No No Fuels in this category are used for space heating, primarily in buildings. Would be too time consuming and difficult to quantify these emissions. Some activity associated with fire work, especially by fleet, is unavoidably captured under the mobile sources emissions. Data for this category were scarce or non-existent and the emissions are de minimis. The majority of fire extinguishers on the Forests do not emit GHGs and this is a de minimis emissions source. Gas waste streams No This activity does not exist on the Forests Indirect Electricity Yes All Forests used electricity and data was easily obtained Imported heat or steam No This activity does not exist on the Forests Optional Employee business air travel Employee commuting Yes Yes The team decided to include this category because the data was relatively accessible and it is important to establish a baseline in as many categories as is possible. This category was included because the data was accessible and it is important to establish a baseline in as many categories as is possible. Future improvements in data storage and capture will improve the quality of data used for this category. Product transport No Would be too time consuming and difficult to quantify these emissions. Off-site waste disposal No Would be too time consuming and difficult to quantify these emissions.

10 Big Picture Perspective Mobile sources are the biggest contributor to GHG emissions across all six Forests Purchased electricity is the second highest source and stationary sources are the third highest source of emissions across all six forests. Take home messages Fleet fuel economy is low. GSA mileage data is of poor quality. Lessons Learned Building ownership plays a role in GHG reduction options. Forest level data sources only capture a small percentage of overall emissions. Wood contributes a disproportionately larger amount of methane and nitrous oxide emissions than fossil fuels. Some Forest Service reporting and data storage systems are outdated and contain inconsistencies and data gaps.

11 Next Steps The National Renewable Energy Laboratory (NREL) will consolidate the results of the FS inventory with other GHG inventories developed by the NPS and USFWS to develop a total emissions footprint. Ultimately, the consolidated GHG inventory will capture anthropogenic emissions on all federal lands in the GYA. The three federal agencies within the GYA will use this inventory to collaboratively set comprehensive emission reduction goals for the 18 million acre Greater Yellowstone Ecosystem.
