Figure 9: Transportation GHG Emissions by Fuel Type, 2005 <br /> <br />Waste:  <br />Managed Landfill Waste: <br />In 2003x, University City produced 14,889 metric tons of waste which in turn resulting in <br />approximately 13,709 metric tons of CO2e. GHG emissions from waste occur during the <br />breakdown of organic waste in landfills. The primary GHG released from landfills is methane, <br />which is twenty-one times more efficient at trapping heat than CO2. These emissions are <br />considered to be Scope 3 emissions because they are not generated in the base year, but will <br />result from the decomposition of the 2003 waste over the full 100+ year cycle of its <br />decomposition. Paper products constitute the largest percentage of GHG emissions from waste, <br />with food waste being the second largest emitter. <br />Table 13: 2005 Landfill Community GHG Emissionsxi <br /> CH₄ <br />(kg) <br />CO₂e <br />(metric <br />tons) <br />CO₂e <br />(%) <br />Paper Products 481,20110,1051.9 <br />Food Waste 93,1821,9570.4 <br />Plant Debris 40,6188530.2 <br />Wood or Textiles 14,3363010.1 <br />All Other Waste 000.0 <br />Subtotal Landfill 629,33713,2162.5 <br /> <br /> <br />2010-2011 Greenhouse Gas Emissions Inventory, City of University City, MO 21 <br /> <br />15.9% <br />84.1% <br />Diesel <br />Gasoline
