Community -wide Greenhouse Gas Emissions Profile <br />St. Louis Park has participated in the Regional Indicators Initiative (RII) since 2009. RII has completed a <br />greenhouse gas inventory for the city for all years between 2007 and 2016, and has made projections for <br />"businesses -as -usual" emissions looking out to 2040. Business -as -usual shows the anticipated emissions if the <br />city were to take no action to reduce its emissions. This information was captured using the wedge diagram tool, <br />which divides the emissions by sector (building energy, transportation, waste, and wastewater), as seen in <br />Figure 1. This graph illustrates that if the city were to do nothing to actively reduce emissions, there would be a <br />slight rise in emissions overtime. <br />BUSINESS -AS -USUAL EMISSIONS BY SECTOR <br />tonnesCO2e <br />1,000,000 <br />�:aax1aaIIIIIII <br />700,000 <br />600,000 <br />500,000 <br />400,000 <br />300,000 <br />200,000 <br />100,000 <br />■ Waste and Wastewater <br />■ Vehicle and Air Travel <br />■ Residential Natural Gas <br />Residential Electricity <br />■ C/I Natural Gas <br />• C/I Electricity <br />2005 2010 2015 2020 2025 2030 2035 2040 <br />Figure 1 Business as usual emissions by sector. Data from the Regional Indicators Initiative. <br />The greatest emissions sources are from buildings and transportation. The building sector includes emissions <br />from all commercial, industrial, and residential buildings. This includes electricity, which is primarily used for <br />lighting, appliances, and other electronic devices, but can be used for space and water heating as well. Natural <br />gas is the main fuel for space and water heating, <br />cooking, and many industrial processes. <br />Emissions from buildings make up 58% of all <br />emissions in St. Louis Park (Figure 2). <br />Transportation makes up 39% of total emissions <br />within the community. Emissions from <br />transportation are attributable to car and truck <br />travel, and are estimated by vehicle miles <br />traveled within the city boundaries (regardless <br />of through traffic or with an origin or destination <br />in the city). The remaining emissions come from <br />waste and waste water treatment, which make <br />up less than 3%of total emissions. <br />Building emissions can be broken down further <br />into two sectors: residential and commercial. <br />39% <br />ALL EMISSIONS BY SECTOR <br />■Total Building <br />■Transportation <br />■Solid Waste <br />'B% ■ Wastewater <br />Treatment <br />Figure 2 Percent of emissions by sector.
