City of St Louis Park Greenhouse Gas Assessment <br />City Operations, 2005 to 2015 <br />34 tomes of GHG per year.' Over the 10-year study period, the City's annual reductions below <br />the 2005 base year's emissions totaled nearly 8,000 tomes. On average over the 10-year period, <br />the City's reductions would offset the equivalent annual emissions from about 28 households. <br />Figure 7 illustrates this concept. For example, in 2010, the City's emissions were 506 tomes <br />lower than in 2005. That is the equivalent of the average emissions from 17 households in the <br />City that year. <br />Figure 4: Greenhouse Gas Emissions by Fuel Sources. 2005 to 2015 <br />10,102 <br />0% <br />10,000fR8,295 <br />9596 <br />-z% <br />Liquid fuels <br />4% <br />8,000-6% <br />Sewers <br />m <br />8% <br />F 6,000to% <br />Potable ater <br />w <br />4,000 <br />-12%aiiiiiiiiiiiiiia Streetlights, signals and <br />-14% flashers <br />2,000 <br />-16% � Buildings and facilities <br />18% <br />_ — — Reduction from 2005 <br />_ <br />-20% <br />baseyear <br />2005 2010 2015 <br />Figure 5: Greenhouse Gas Emissions Compared to 2005 Base Year, Totals and Normalized, <br />2005 to 2015 <br />5% <br />----Triple <br />normalized <br />4010 <br />emissions <br />- <br />—Actual <br />emissions <br />-20% <br />0% <br />0.0% <br />0.0% <br />0.0% <br />0.0% <br />-0.1% <br />1 2% <br />0% <br />zoos <br />z�g <br />zoo9 <br />zolo zo zeta <br />auli <br />14 <br />zols <br />° <br />-2% <br />` <br />-5% <br />10% <br />$% <br />-11% <br />15% <br />-12% <br />-14% <br />Normalizing emissions: In order to obtain a more accurate picture of the energy consumption <br />and GHG emissions associated with energy consumption, it is valuable to screen out factors that <br />affect consumption and emissions but are beyond the control of the City; namely, weather and <br />the GHG emission factors for the electric utilities. Weather does not have a significant effect <br />overall but utility emission factors are very important since electricity consumption is the <br />dominant source of emissions for City operations (64% of total emissions in 2015). <br />s The data for the citywide greenhouse gas emissions attributable to the average household in St Louis Park is from <br />the Regional Indicators Initiative (years 2007 to 2013). Linear regression analysis provided estimates for 2005, <br />2006, 2014, and 2015. Source: httpJ/www.regionalindicaLorsmn.com <br />8 <br />ORANGE <br />ENVIRONMENTAL <br />
