IL is a big emitter; electricity & transport lead
• Total Illinois GHG emissions 2003: 274.7 million metric tonnes
• 5th largest GHG emitting state in the U.S.
• Roughly equal to total emissions of the Netherlands

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%
