INTRODUCTION The Alameda-Contra Costa County Transit District (AC Transit) has committed to The Climate Registry (TCR) to estimate and report its greenhouse gas (GHG) emissions. Following the guidelines described by TCR, this commitment involves the estimation of GHG emissions resulting from AC Transit business practices, compilation of a GHG inventory and reporting of the inventory results via the Climate Registry Information System (CRIS). This Inventory Management Plan (IMP) outlines the procedures and guidelines followed during preparation of AC Transit’s 2009 GHG Inventory for TCR, designed to meet the requirements of TCR’s General Reporting Protocol.1 The IMP serves as a centralized record for reporting elements, boundary descriptions, assumptions, methodologies, and other documentation associated with the AC Transit GHG Inventory. It is considered a living document that will be revised and updated annually to keep information on the inventory current and easy to follow. 2. INFORMATION ABOUT THE ORGANIZATION AC Transit is the fourth largest transit agency in California and the third largest bus-only transit operator in the United States. AC Transit provides the primary public transport service within the San Francisco East Bay region, while BART (the Bay Area’s high-speed electric rail system) provides most regional connections to San Francisco and elsewhere. The AC Transit District (the District) includes an extensive network of local, express and Transbay routes blanketing 13 cities and adjacent unincorporated areas in Alameda and Contra Costa Counties along the east shores of San Francisco and San Pablo Bays. It includes older urban, higher density areas such as Oakland, Berkeley and Alameda, along with newer, lower-density areas. Among transit districts in California, AC Transit has the third highest population density, after San Francisco and Los Angeles.

GEOGRAPHIC SCOPE AND REPORTED GASES TCR requires its members to report on an annual basis, with no breaks in reporting. At a minimum, members must report at least 95% of their entity-wide emissions of carbon dioxide (CO2) for certain direct and indirect emissions. In the first two years after joining TCR, members must report at a minimum their CO2 emissions in California or nation-wide, depending on the geographic scope of the inventory. Starting with the third year, members must report all six Kyoto gases - CO2, methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulfur hexafluoride (SF6), entity-wide. The CY2009 GHG Inventory represents AC Transit’s first year of reporting to TCR. The geographic scope of the AC Transit GHG Inventory is the State of California and the chemical boundary is CO2 in this first year of reporting (CY2009). 4. ORGANIZATIONAL BOUNDARY The organizational boundary encompasses all the facilities and operations that AC Transit owns or controls in the geographic boundary (State of California). AC Transit is 5 | Page AC Transit – GHG Inventory Management Plan, CY2009 Inventory reporting all of the associated CO2 emissions for those operations and facilities that it wholly owns. For those operations in which AC Transit has a partial ownership or working interest, or holds an operating lease, there are two accounting options for reporting CO2 emissions: 1. Management control – • Report 100% of emissions for facilities which participant has management control (determined using either operational or financial criteria consistently across all operations); • Report 0% of emissions for facilities which participant does not have operational or financial control. 2. Equity share – . Percentage of emissions accounted for as proportionate to ownership. AC Transit has chosen to delineate its organizational boundary using the operational criteria under management control. Therefore, AC Transit is reporting 100% of emissions associated with the facilities and operations for which it has operational control. Table 1 (below) lists the facilities within the organizational boundary of AC Transit during CY2009, as determined by operational management control. The Newark facility is currently occupied by a tenant under an operational lease and is deemed to be outside AC Transit’s operational management control; thus it is excluded from the organizational boundary. A new facility was purchased partway through 2008 at 66th Ave. The 66th Ave facility is leased to tenants who are responsible for 11 of the 14 meters present at the location. Table 1.
