November 9, 2009 Section 2: Greenhouse Gas Inventory and Forecast 2. Greenhouse Gas Inventory and Forecast In 2008, a comprehensive community-wide inventory was developed by Local Governments for Sustainability (ICLEI) to establish the context within which to assess GHG emission reduction opportunities in the City of San Leandro. The inventory provides an important foundation for the Climate Action Plan, providing the 2005 baseline against which progress toward the City goal of reducing greenhouse emissions 25 percent below 2005 levels by 2020 can be measured. The inventory includes abusiness-as-usual forecast of greenhouse gas emissions for the year 2020, which enables the City to estimate the amount of emissions reductions needed to meet their goal. ICLEI's Cities for Climate Protection methodology for emissions inventories enables local governments to systematically estimate and track greenhouse gas emissions at the community- wide scale and those resulting directly from municipal operations. The greenhouse gas inventory results outlined in this chapter are adapted from ICLEI's "City of San Leandro Baseline Greenhouse Gas Emissions Inventory Report" from June 2008, as part of ICLEI's Cities for Climate Protection Campaign. 2.1 Inventory Sources and Data Collection Process An inventory of greenhouse gas emissions requires the collection of information from a variety of sectors and sources. As outlined in the ICLEI report, the community electricity and natural gas data was collected from Pacific Gas & Electric (PG&E) company. The transportation related emissions were estimated from data sourced from The Metropolitan Transportation Commission (MTC), CalTrans, Bay Area Air Quality Management District (BAAQMD), and Bay Area Rapid Transit (BART). Solid waste data was gathered from the California Integrated Waste Management Board Disposal Reporting System. The community inventory represents all the energy used and waste produced within the City of San Leandro and its contribution to greenhouse gas emissions. The municipal inventory is a subset of the community inventory, and includes emission derived from internal government operations. There are two main reasons for completing separate emissions inventories for community and municipal operations. First, the City is committed to action on climate change, and has a higher degree of control to achieve reductions in its own municipal emissions than those created by the 4 http;/Iwww.ciwmb.ca.gov/Igcentral/DRS/Reports/default.asp ~8~ s~rw ~~q~~ Page 6 of v ti~~,c~` ~~
