Best practices which Elk River Municipal Utilities <br />may be able to leverage for continued fuel efficiency include: <br />Efficiently use existing fleet of ERMU vehicles by encouraging trip bundling, video <br />conferencing, carpooling, vehicle sharing and incentives/technology. <br />No-Idling practices and policies <br />Vehicle replacement plan to migrate to electric and hybrid vehicles. <br />Explore Efficiency Programs focused on diesel engine retrofits, installation of <br />auxiliary power units <br />How do ERMU Vehicles contribute to Greenhouse Gas Emissions? <br />Fossil Fuels used in transportation produce GHG when burned, primarily CO2. In fact, the <br />weight of CO2 produced actually exceeds the weight of the fuel burned. The amount of GHG <br />produced by common vehicle fuels ranges from 19.4 pounds per gallon for gasoline to 22.5 <br />pounds for diesel. <br />Nationally, Americans drive over 3 trillion miles annually, producing 1.2 billion Metric Tonnes of <br />vehicle related GHG emissions.* <br />*For more information:http://www.bluedotregister.org/carbon-copy/2014/12/11/a-mountain-of-an-impact-the-carbon-footprint-of- <br />american-roads <br />ERMU Operations <br />ERMU Vehicles <br />Annual Greenhouse Gas equal to: <br />3,881,696 <br />Cubic Feet of <br />Man-Made <br />Atmosphere <br />197.83 <br />Metric Tonnes <br />Summary of Findings* <br />ERMU owns and operates vehicles as a critical support to all functions related to providing <br />electrical and water utilities to its customers. During the 2015 Baseline year, ERMU’s vehicle fleet <br />used 14,310 gallons of gasoline and 6,930 gallons of diesel fuel. The emissions volume <br />associated with the fleet’s fuel consumption totaled 197.83 Metric Tonnes (436,139 pounds) <br />CO2e, approximately 0.16% of community wide vehicle emissions**. <br />* Sources: City of Elk River data, emission factors based on US EPA and EIA. <br />**Based on Regional Indicators Initiative data. <br />12.91% <br />ERMU Operations <br />Total <br />Volume Visualization <br />On average, the emissions from each ERMU vehicle produce a quantity of man-made <br />atmosphere filling a volume the size of the vehicle.163 times <br />130’ long <br />According to the US EPA: <br />The amount of carbon dioxide (CO2) that is <br />produced from burning a fuel weighs more <br />than the amount of the fuel itself, because <br />during complete combustion, each carbon <br />atom in the fuel combines with two oxygen <br />atoms in the air to make CO2. The addition <br />of two oxygen atoms to each carbon atom <br />forms CO2, which has an atomic weight of <br />44—roughly 3.6667 times the atomic weight <br />of the carbon, which is 12. <br />How can GHG <br />emissions weigh more <br />than the fuel we burn
