3.2 Out -of- Boundary Activities <br />Out -of- boundary activities (scope 3) are added to in- boundary emission sources to create a <br />more holistic picture of Louisville's CO2e footprint. These activities include: <br />• Embodied Energy of Urban Materials: This includes energy use and associated GHG <br />emissions from producing key urban materials such as transport fuels, food, and <br />shelter (cement for concrete), necessary to support life in cities. <br />• Airline Travel: Energy use for airline travel is important as it appears in national and <br />statewide GHG inventories and in personal calculators. At the city- scale, these <br />appear as out -of- boundary emissions, particularly when the airport is outside city <br />boundaries (as is the case of Louisville). <br />3.3 Energy Use Sectors <br />It is useful to communicate a community's energy use and GHG emissions in terms of major <br />emitting sectors. This report will focus on the following three sectors: <br />• Buildings Sector: Energy use (electricity and natural gas) in residential and <br />commercial buildings and industrial facilities. <br />• Transport Sector: Energy (gasoline and diesel) used to operate personal vehicles, <br />commercial trucks and airplanes. <br />• Materials Sector: Energy use and associated GHG emission from producing critical <br />urban materials (food, transport fuels, water, cement) and waste disposal. <br />3.4 Buildings Sector <br />Greenhouse gas emissions attributable to Louisville's building sector were calculated using <br />primary data obtained from an Xcel Energy Local Government Consumption Report via David <br />12 <br />14 <br />
