ILLINOIS GREENHOUSE GAS EMISSIONS AND SINKS INVENTORY: SUMMARY IL Greenhouse Gas Emissions, 1990 and 2003 250.0 200.0 150.0 LU <3 P 100.0 50.0 0.0 -50.0 3 ~ 1990 ¦ 2003 Energy Industrial Agriculture Land Use Waste Processes Sector The Illinois Climate Change Advisory Group report entitled Illinois Greenhouse Gas Emissions Inventory and Projections provides estimates for Illinois' greenhouse gas (GHG) emissions by sector for 1990 and 2003.1 In 1990, Illinois emitted GHGs in the amount of 223 million metric tons carbon dioxide equivalent (MMTC02E). In 2003, total net GHG emissions in Illinois increased by 20 percent to 267.5 MMTC02E. Emissions from the energy sector grew by 16 percent between 1990 and 2003 and emissions from the industrial processes sector increased by 274 percent.2 Emissions from both the agriculture and waste sectors declined by 6 percent and 26 percent, respectively. 1 Historical GHG emission estimates (1990 through 2003) were developed using a set of generally accepted principles and guidelines for state GHG emission inventories relying to the extent possible on Illinois-specific data and inputs. Many of the inventory estimates came from the U.S. Environmental Protection Agency's (EPA's) State Inventory Tool. 2 The cause of the increase in emissions from the industrial processes sector is not provided in the Illinois Greenhouse Gas Emissions Inventory and Projections report and the estimates are highly uncertain. ------- Land use accounted for a sink, which declined significantly by 48 percent between 1990 and 2003 due to both an increase in agricultural and urban areas coupled with a decrease in rural grasslands and forested areas. 1990 C02 (MMTCOzE) ch4 (MMTCOzE) n2o (MMTC02E) HFCs, PFCs, and sf6 (MMTC02E) Total (MMTCOzE) Energy * * * * 198.8 Industrial Processes * * * * 3.5 Agriculture * * * * 25.9 Land Use * * * * -14.3 Waste * * * * 9.2 Net Emissions * * * * 223.0 2003 C02 (MMTCOzE) ch4 (MMTCOzE) NzO (MMTCOzE) HFCs, PFCs, and sf6 (MMTCOzE) Total (MMTCOzE) Energy 226.5 2.2 2.0 0.0 230.7 Industrial Processes 8.2 0.0 0.0 4.9 13.1 Agriculture 0.0 3.0 21.3 0.0 24.4 Land Use -7.4 0.0 0.0 0.0 -7.4 Waste 0.0 6.1 0.7 0.0 6.8 Net Emissions 227.3 11.3 24.0 4.9 267.5 Note: Totals may differ from the sum of the sources due to independent rounding. All emissions are reported in million metric tons of carbon dioxide equivalent (MMTC02E). * The Illinois state Inventory did not include emissions by gas for 1990; thus, emissions of all gases, expressed in C02 equivalents, are presented in the right-most column. The vast majority (86 percent) of net GHG emissions in 2003 came from the energy sector, with 32 percent of total net emissions from electricity generation. Agriculture represented 9 percent of net GHG emissions for 2003, which was mostly a result of livestock production and soil use. Gross per capita emissions from Illinois were 21 MTC02E in 1990 and 22 MTC02E in 2003 which is slightly less than the gross per capita national average of 25 MTC02E for both years. ------- |
