Summary of the WRAP’s Emission Inventory for Carbon

1. Summary of the WRAP’s Emission Inventory for Carbon Alice Edwards, Alaska Dept. of Environmental Conservation WRAP Fire, Carbon, and Dust Workshop Sacramento, CA May 23, 2006

3. Emission Inventory Sources • WRAP stationary and area sources • Eastern Research Group • Enhanced and projected the 2002 NEI with QA and state input/review • http://www.wrapair.org/forums/ssjf/documents/eictts/index.html • CA emissions obtained separately from ARB

4. Emission Inventory Sources • WRAP mobile sources • ENVIRON • Surveyed state/local agencies for model inputs • Applied MOBILE and NONROAD models for 2002, 2008, 2012, and 2018 • Separate methods for locomotives, airports, and marine sources • Draft report available soon on WRAP website • CA emissions obtained separately from ARB

5. Emission Inventory Sources • WRAP fire sources • Air Sciences, Inc. • Wildfire, wildfire use, prescribed fire, agricultural, and non-federal rangeland categories • Phase II: 2002 actual emissions • Phase III: 2000-04 planning emission • Phase IV: 2018 planning emissions • http://www.wrapair.org/forums/fejf/index.html

6. Emission Inventory Sources • Biogenic VOCs • Developed by the WRAP Regional Modeling Center (RMC) using the BEIS model • Emissions outside WRAP region • Mexico • http://www.wrapair.org/forums/ef/docs.html • Canada, other U.S. states, non-mobile ocean • Obtained by WRAP RMC through an inter-RPO process • Boundary conditions • Obtained by WRAP RMC from Harvard Univ., which used the global GEOS-CHEM model
