25E - AGMT - GAS EMISSIONS INVENTORY ACTION PLAN

Home Browse Search

AECOM will lead the execution of the inventory and forecast, with additional technical support from ICLEI. Fehr and Peers will perform data collection and contribute to emissions analysis for the transportation sector. The inventory and forecast methodology will follow the most current and widely-accepted standards. For government operations emissions, the inventory will comply with the Local Government Operations Protocol (LGO Protocol), which was developed in 2008 through a partnership between ICLEI, the California Air Resources Board, the California Climate Action Registry, and The Climate Registry. For community-scale emissions, the inventory will rely on current best practices in California and will be informed by guidance from the California Air Resources Board, the California Attorney General's Office, the Association of Environmental Professionals, and the South Coast Air Quality Management District. Analysis will also be performed to align the community-scale inventory with guidance coming out of ICLEI's Community Protocol development process. The Community Protocol is scheduled for release in 1St Quarter 2012, so while the final document may not be available upon initiation of the inventory, ICLEI will communicate the guidance that is likely to be included in the Protocol. Task L GHG Emissions Inventory The GHG emissions inventory will be developed through the following subtasks. Subtask 1a. Identify Baseline Year AECOM will assist the City in identifying an industry-standard base year that allows for assembly of a complete data set, while also allowing significant recent actions to be demonstrated against the baseline. The identification of a reasonable baseline year will require consideration of data availability from all key data sources, as well as local considerations. AECOM will work with City staff to identify and contact required data providers, develop an understanding of the availability and limitations of data sources, and explore possible operational changes which may have occurred in the recent past which would affect the relevance of historical data. Subtask 1b. Identify Data Sources and Collect Data Through meetings with key departmental staff, AECOM will identify the data needs and expected sources for the government operations and community inventories. Data needs and expected sources will be determined using the above-referenced standards as a guide. In cases where primary data sources are incomplete, secondary sources may be used to augment or substitute for primary data sources. During this stage, Fehr and Peers will generate VMT data for use in determining community-wide transportation emissions, utilizing the Orange County Transportation Authority Travel Demand Model (OCTAM) to ensure that vehicle miles travelled (VMT) is accurately accounted for and attributed only to travel related to the Santa Ana community. In addition to the required data for determining emissions, a variety of indicator data will also be collected for benchmarking purposes. This may include such indicators as square footage of buildings and government facilities, number of full time-equivalent employees, community population and employment, or economic activity, enabling additional levels of data analysis and future comparability. This information may also be used in setting the emission reduction target, if an efficiency-based target is desired and determined appropriate for Santa Ana. 25tLl5
