2012. This number was then multiplied by the emission factor described below to obtain the total emissions associated with air travel for Louisville. 3.5.3 Emission Factors for Diesel, Gasoline & Jet Fuel The following emissions factors were used to calculate total transportation emissions: 9.1 kg- 0O2 /gallon for gasoline fuel, 10.2 kg -0O2 /gallon for diesel fuel and 9.9 kg -0O2 /gallon for jet fue12. The emissions factors for transportation fuels were multiplied by the total fuel consumption for gasoline, diesel and jet fuel to determine the total GHG emissions associated with on -road and airline transportation. 3.6 Materials & Waste Sector The materials sector comprises several sources of GHG emissions including cement, water and wastewater, fuel production, food production, and municipal solid waste (MSW). 3.6.1 Transportation Fuel Production The methodology outlined in section 3.5 calculates the direct, tailpipe emissions associated with burning gasoline, diesel, and jet fuels. There are also embodied emissions associated with the production of these fuels. The GHG emissions factors for producing transport fuels were obtained from GREET Well -To -Pump analysis as 2.5 kg -0O2e /gallon for gasoline and 2.0 kg -0O2e /gallon for diesel and jet fuel12. These emission factors were multiplied by the number of gallons consumed in 201211 to find the embodied emissions attributable to Louisville. 3.6.2 Water & Wastewater In 2012 the City of Louisville treated a total of 2 billion gallons of water (wastewater included) according to primary data collected by Dave Szabados13. According to the Local Governments Operating Protocol2, depending on the way a jurisdiction treats its wastewater, there can be stationary emissions (methane), process emissions (nitrous oxide), and fugitive emissions (methane). Since Louisville's wastewater treatment plant does not use a lagoon for treatment, 15 17
