The City of Fairfield just completed a greenhouse gas inventory, and while Fairfield’s emissions are below national averages, we have a lot of work ahead of us!
Mayor Malloy signed the U.S. Mayors Climate Protection Agreement in October 2009, committing Fairfield to targeted reductions of Green House Gas emissions that contribute to climate change. After signing this agreement, Fairfield City Council voted to join the International Council for Local Environmental Initiatives (ICLEI), funded by the Iowa Power Fund Grant. The Green House Gas (GHG) inventory deeply examined the emission outputs of the residential, commercial and industrial sectors within Fairfield’s City limits; as well as a separate examination of Fairfield’s municipal operations. Fairfield’s transportation data, provided by the DOT and French-Reneker-Associates, Inc, was examined to account for fossil fuel usage and emissions.
Multiple greenhouse gasses were tabulated (CO2, CH4, N2O, HFCs, PFCs, SF6), and then converted to a total greenhouse gas equivalent or CO2e, for ease of comparison. One metric tonne equals one thousand kilograms, or approximately 2,205 lbs. Data gathered from these six gasses within specific sectors of the city allow for accurate reporting on resource consumption, and its direct impact on the environment.
The baseline greenhouse gas inventory for Fairfield shows that the total greenhouse gas emission equivalent for the community in 2008 was 144,971 metric tonnes of CO2e. Based on census data for the City, the CO2e emission tonnes per capita is 15.73. Although this less than the average per capita for the US (19.6 metric tonnes), world average carbon emissions are 4 metric tonnes per capita and sustainable limits are estimated to be near 2 metric tonnes per capita (International Energy Agency, Key World Energy Statistics, 2006). The largest contributors to GHG emissions in Fairfield are energy use in buildings and transportation, through electricity usage and fossil fuel consumption respectively.
