City of St Lauds Park Greenhouse Gas Assessment City Operations, 2005 to 2015 Table 3: Takeaways Description X I Y Z Scope 1 and 2 Consumption and Emissions Compared to the 2005 Base Year, GHG tower in 2010 by X%and Y%in 2015. -5% -18% On average over 10-year study period, the City's emission reductions offset the average emissions of 215 about X St. Louis Park households, a total of Z households by 2015. Primary fact" that resulted in GHG reductions was due to Xcel Energy's reduced mission factor. It 13% 22°i was X% lower in 2010 and Y% lower in 2015 compared to 2005. Compared to 2005, the reduced electricity emission factor resulted in the reduction of X tonnes in (1,291) 69% 2015, which equals Y%of the total reduction. Had the electricity ion ssiOn factor remained 9 the 2005 level, GHG emissions would have been X"A 5% 2% higher in 2010 and Y%I ower in 2015 compared to the 2005 base year. Weather did not have a substantive effect on emissions Although electricity is the dominant source of emissions and all bon 2 years (2004 & 2009) during the 10-year study period had higher cooling -degree-days than the 30 -year 'b arm," nationally, only 5% of el ectri city i a used for summer cooling. Winters with higher heating -degree-days (2008, 2013, 2014) tended to balance out warm" winters (2006, 2012, 2015) over the study period Changes to facilities were not a major change factor. The most significant change, the Municipal Service FadEty,more thrm doubled in size but emissions increased from X tonnes in 2005 to Y in 504 6]9 35% 2010, only aY%increase. Triple normalized GHG end ssions(weather, electric utility sort sail on factors, and changed accounts) 5% were virually unchanged in 2010 and X%lower in 2015 compared to the 2005 Base Year. Compared to the 2005 Base Year, a]echicity consumption to produce potable water in 2015 decreased by X% Production of potable water decreased by Z%Thia yielded a Z%increase in -15% -1 w/ 0/. electricity efficieutcy, ballons perkWh. The 9 largest consumers of Energy include (largest to smallest): Potable water, Rec Center, liquid fnda, streetlights and signals, Municipal Service Center Hamilton House, the 2 fire start ons, City Hall, and Pdi ce Dept Compared to 2005, total Energy, consumption for the 9 largest energy commuters were X%high er in 4% 4% 2010 and Y%lower in 2015. Compared to 2005, total GHG ehmisgiuhs for the 9 largest energy consumers were X%lower in 2010 and Y%l ow" in 2015. The reduced emissions were due primarily to the reduced electricity -5 % -18% -22^/o emission fact"; Z%lower in 2015. Eight categories were responsible for virtually all of the reduced emissions in 2015 compared to 2005 (largest to smallest): Potable WaterRec CenterSewers Hamilton House City Hall Police Dept, Li quicilibels, Municipal Service Center. Compared to 2005, these 8 categories were responsible for the reduction of C1HG tonnes. (1,880) Xcel Energy's reduction in its emi ssi on factor was responsible for X of these tomes; Y96 of the total (1,297 67K Reduced electri d ty conmumptiom among these l argest energy consumers resulted in the reduction of 000) 16/0 X tomes; Y% of the total. Reduced natural gas consumption among these largest energy consumers resulted in the reduction of (219) 12/o X tomes; Y% of the total. The emission reductions from the 8 of the msj err facilities were offset by the increased emissi cars (X 146 tonnes) from the 2 fire stations and dreetlightsdsignals. Scope 3 Cmrsmrptim and Emissions Scope 3 entissions were significantly lower in 2015 compared to 2005 (X tomes and Y%). This is (3,216) 49% primarily due to per -gallon emission reductions at the Metropolitan Treatment Plant. Treatment of the citywide sanitarysewer cischarges at the Metropolitan Treatment Plantresultedin 33K (3,160) -59i X GHG tonnes in 2015. This was Y tonnes less than in 2005, a Z%decrease Management of solid waste management waste generated by City operations was X manes lower in (62) 48°/ 2015 compared to 2005; a YIN, decrease.
