November 9, 2009 <br />Section 2: Greenhouse Gas Inventory and Forecast <br />The residential, commercial, and industrial sectors represent emissions that result from <br />electricity and natural gas used in both private and public sector buildings and facilities. The <br />transportation sector includes emissions from private, commercial and fleet vehicles driven <br />within the City's geographical boundaries as well as the emissions from transit vehicles and the <br />city-owned fleet. Figure 1 shows the proportion of San Leandro's total greenhouse gas <br />emissions from all major sources for the year 2005. <br />Figure 1. City-wide Emissions by Sector (2005) <br />Transportation - <br />Building Energy <br />Residential, <br />12% <br />Building Enerl <br />Commercial <br />Industrial, 24% Waste, 3% <br />sway, 45% <br />~ ransportation - <br />Local roads, <br />16% <br />As shown above, the two largest categories of emissions are related to building energy use <br />(both residential and commercial & industrial) and transportation (highway travel and local <br />travel). <br />2.2.1 Building Energy Emissions <br />In 2005, San Leandro's total stationary energy consumption was about 608,822,401 kilowatt- <br />hours (kWh) of electricity and 31,495,523 therms of natural gas, excluding municipal facilities. <br />Stationary energy use by all community sectors (residential, commercial and industrial <br />activities), primarily the combustion of natural gas, accounts for 36 percent of total greenhouse <br />gas emissions in San Leandro. San Leandro's stationary energy use resulted in a total of <br />approximately 342,725 metric tons of CO2e emissions in 2005. <br />Figure 2 shows the breakdown of greenhouse gas emissions by sector for both electricity and <br />natural gas combined. Of the total 342,725 metric tons of COze emitted due to building energy <br />use, 33 percent was from residential buildings and 67 percent was from commercial and <br /> <br />Page 8 <br />~~Qa4a' <br />
