December 21, 2009 Section 2: Greenhouse Gas Inventory and Forecast The residential, commercial, and industrial sectors represent emissions that result from electricity and natural gas used in both private and public sector buildings and facilities. The transportation sector includes emissions from private, commercial and fleet vehicles driven within the City's geographical boundaries as well as the emissions from transit vehicles and the City-owned fleet. Figure 1 shows the proportion of San Leandro's total greenhouse gas emissions from all major sources far the year 2005. Figure 1. City-wide Emissions by Sector (2005) Building Energy Residential, 12% ~ Building Energy Commercial & Industrial, 24% Waste, 3% Transportation - Highway, 45% Transportation - Local roads, 16% As shown above, the two largest categories of emissions are related to building energy use (both residential and commercial & industrial) and transportation (highway travel and local travel). 2.2.1 Building Energy Emissions In 2005, San Leandro's total stationary energy consumption was about 608,822,401 kilowatt- hours (kWh) of electricity and 31,495,523 therms of natural gas, excluding municipal facilities. Stationary energy use by all community sectors (residential, commercial and industrial activities), primarily the combustion of natural gas, accounts for 36 percent of total greenhouse gas emissions in San Leandro. San Leandro's stationary energy use resulted in a total of approximately 342,725 metric tons of C02e emissions in 2005. Figure 2 shows the breakdown of greenhouse gas emissions by sector for both electricity and natural gas combined. Of the total 342,725 metric tons of C02e emitted due to building energy use, 33 percent was from residential buildings and 67 percent was from commercial and Page 9
