Mobile Emissions SourcesSan Leandro 2005 <br /> <br />December 21, 2009 Section 2: Greenhouse Gas Inventory and Forecast <br />Figure 3 shows the breakdown of greenhouse gas emissions by vehicle miles traveled (VMT) <br />from local roads and VMT from state highways. Of the total 577,623 metric tons of COe <br />2 <br />emitted, 27 percent was from local roads and 73 percent was from state highways. <br />Figure 3. Transportation Emissions – Highways v. local road travel <br />Local Roads <br />27% <br />State HWY <br />73% <br /> <br />Source: ICLEI CACP Model output <br />Calculations for transportation emissions are based on figures for total vehicle miles traveled <br />(VMT) in the City of San Leandro. MTC supplied the necessary VMT data, while BAAQMD <br />provided data to break down total VMT by percentage driven by a given vehicle type. <br />2.2.3 Solid Waste Emissions <br />In 2005, San Leandro sent approximately 160,050 metric tons of solid waste to landfills resulting <br />in 28,956 metric tons of COe emissions. San Leandro has recycling measures in place to <br />2 <br />reduce the amount of waste sent to landfills. <br />Emissions from waste result from organic materials decomposing in the anaerobic environment <br />of a landfill which produces methane—a greenhouse gas 21 times more potent than carbon <br />dioxide. Table 2 shows the approximate breakdown of the materials San Leandro sent to <br />landfills in 2005. Materials that do not release greenhouse gases as they decompose are <br />included in the “All Other Waste” category. <br /> <br /> <br /> <br />Page 11 <br /> <br /> <br />
