A greenhouse gas emissions inventory is a tool that quantifies carbon dioxide and related emissions so that a community can both set baseline data and regularly assess progress toward meeting local goals for reducing emissions.
2022 GHG Emissions Inventory Update
In July 2026 the EAC completed the GHG emissions inventory for the 2022 data year while expanding the geographic scope of the study. Previous inventories included only the Bloomington-Normal urban area but for 2022 the entirety of McLean County is now evaluated. This latest GHG inventory is paired with the pending community-wide Community Energy Strategic Plan (CESP) to identify strategies for emissions reduction and energy capacity needs. The CESP is in final stages of review and will soon be available for public comment.
This program is offered in partnership with the Illinois Environmental Protection Agency Office of Energy and supported by funding from the U.S. Department of Energy.
The 2022 GHG Emissions Inventory is available for download as pdf.
2015 GHG Emissions Inventory Update
In 2023 the EAC finalized the 2015 GHG Emissions Inventory update. This update compares the 2008 baseline data with new data collected in 2015 showing where emissions have increased or decreased over the years.
See how emissions have changed from 2008-2015 in both Community Scale and Local Government Operations.
2008 Baseline GHG Inventory
In 2014 the Ecology Action Center completed the first inventory of greenhouse gas (GHG) emissions for the Bloomington-Normal community. 
Results are contained in the EAC’s report, Bloomington-Normal Greenhouse Gas Inventory–Local Government Operations and Community-Scale Emissions, Baseline Year: 2008, available for download online. The per capita emissions and sources for Bloomington-Normal for 2008 closely mirrored state and national rates and trends for that year.
The baseline study reveals that the leading sources of greenhouse gases in Bloomington-Normal are stationary energy usage such as electricity and natural gas for cooling, heating, and other needs including lighting and refrigeration in homes, businesses, industry, and local government. Electricity and natural gas emissions account for over three-quarters of the community-wide emissions. Vehicular transportation followed at almost 20% of the emissions. Stationary energy and transportation emissions are primarily attributable to the combustion of fossil fuels.
With the results from similar studies in hand, communities across the nation are implementing common-sense strategies that not only help reduce climate-changing greenhouse gases, but also save money, conserve energy, improve air quality, and preserve precious natural resources. The City of Bloomington and Town of Normal provided funding for this emissions study.
