1. Illinois Greenhouse Gas Emissions Inventory and Projections: 1990-2020 Meeting of the Illinois Climate Change Advisory Group 300 West Adams St., 2nd Floor, Chicago, IL February 22, 2007 Governor Rod R. Blagojevich Climate Change Advisory Group

2. 2 Topics to Cover Data Sources and the Climate Analysis Indicators Tool (CAIT) Greenhouse Gases in Illinois and the U.S. Illinois Greenhouse Gas Projections to 2020 Discussion

10. Governor Rod R. Blagojevich Climate Change Advisory Group10 Projections methodology: Transportation, Residential, Commercial and Industrial sector growth rates are based on EIA projections for energy use in the East North Central region (IL, IN, MI, OH and WI) Electric generation and non-energy sector growth rates are derived from historic trends Illinois total GHG emissions are projected to increase at an annual rate of 1.00%

11. Governor Rod R. Blagojevich Climate Change Advisory Group11 Actual Projected IL GHGs projected to be 326 MtCO 2 e by 2020 Illinois actual and projected GHG Emissions 1990-2020 Best Guess: 37.2% above 1990 levels = 88 MtCO 2 e Low High Best Guess

12. Governor Rod R. Blagojevich Climate Change Advisory Group12 EIP could cut 22.9 million tonnes from projected emissions by 2020 1990 levels Illinois actual and projected GHG Emissions with Energy Independence Plan measures 1990-2020 26% below best guess case in 2020 Actual Projected
