Page 9 Government Greenhouse Gas Emissions in 2005 Detailed Report Equiv C02 Equiv C02 Energy Cost (tonnes) (%) (MMBtu) ($) emissions factor includes CH4 and N20 emissions in C02 equivalents. The business-as-usual projections for 2020 assume no change in the PG 8 E COze emissions factor. 2. Default criteria air pollutant emissions factors are based on the Region 13 -Western Systems Coordinating CouncillCNV Average Grid Electricity Set. Data Sources: 1. Data provided by Maria Lara, Management Analyst, City of Pleasanton, (925) 931-5009, mlara@ci.pleasanton.ca.us. 2. Data source fle:Pleasanton OS electricity use.xls. 3. The updated 2005 PG&E C02e emission factor of 0.49 Ibs/kWh of delivered electricity is certifed by the California Climate Action Registry and was reported to ICLEI in January 2007 by Greg San Martin. The PG&E C02e emissions factor of 53.05 kg/mmbtu of delivered natural gas, verified by the California Climate Action Registry and the CEC. Data entered by Ayrin Zahner, Program Associate, ICLEI, ayrin.zahner@iclei.org, (510) 844-0699, in May 2008.

Methane recovery factor derived from the US EPA AP 42 Emissions Factors report (<htto://www.eoa.aov/ttn/chief/ao42lindex.html>), which states that "reported collection efficiencies typically range from 60 to 85 percent" (AP 42, section 2.4 Municipal Solid Waste, 2.4-6). Following the recommendation of the Alameda County Waste Management Authority, and keeping with general IPCC guidelines to err towards conservative estimation, ICLEI adopted the 60°/ end of the range. 3. All disposal figures included in this inventory refer specifically to tons of waste sent to a landfill. Therefore, the tonnage fgures used do not reflect total waste generation, but the amount of waste disposed in a land/ill. This means [hat, in the case of MSW, any waste that was diverted from the landfll through recycling, composting, construction material re-use programs, etc. is not included in the tonnage fgures used to calculate emissions 4. Tonnage includes garbage collected from downtown facilities, the aquatic center, senior center, city offices, and corporation park. Parks are not included. 5. Tonnage is from the year 2007, which is being used a s proxy for 2005 as data for 2005 is not available. Data Sources: 1. Data source ile: email from Maria Lara on 3/4/2008.
