City of Pleasanton <br />GHG Inventory, Forecast, and Targets Methodology and Calculations <br /> <br />26 <br />Pleasanton was derived from the California Air Resources Board California Landfill Emissions Tool <br />Version 1.3, shown in Table 14 and Table 15 respectively. <br />Figure 3 Waste Generation Methodology <br /> <br />In 2017, Pleasanton produced 102,316 tons of solid waste and 367 of ADC waste.48 A CO2e emissions <br />factor for mixed-waste of 0.286 MT CO2e/ton was established and multiplied by the total solid waste <br />disposed of from the community to calculate emissions from waste generated in 2017 of 29,267 MT <br />CO2e. For ADC waste, a CO2e emissions factor of 0.246 MT CO2e/ton was established and multiplied by <br />the total ADC waste disposed of from the community to calculate emissions from waste generated in <br />2017 of 90 MT CO2e. These emissions factors include the expected lifetime emissions associated with <br />the specified tonnage of waste sent to landfill. The emissions factors were developed using SW 4.1 as <br />well as the relative waste stream percentages of different organic materials to establish a methane <br />emissions factor. From 2005 to 2017 GHG emissions from community waste decreased by 6,139 MT of <br />CO2e. This was due to a combination of factors including a reduced solid waste emission factor as well <br />as an overall reduction in waste generation of 18,370 tons. Total waste emissions for 2017 are <br />summarized in Table 16. <br /> <br />48 CalRecycle. 2017. Local Government Information Center.
