County of San Diego 2005/2006 Greenhouse Gas Emissions Inventory

Government
Operations
Inventory Results
This chapter provides a detailed description of San Diego County’s greenhouse gas emissions from government
operations in 2006, rolling up and comparing emissions across sectors and sources as appropriate. This chapter also
provides details on emissions from each sector, including a breakdown of emissions types and, where possible, an
analysis of emissions by department. This information identifies more specific sources of emissions (such as a
particular building) that can help staff and policymakers in the County to best target emissions reduction activities
in the future.
For a report of emissions by scope, and a detailed description of the methodology and emission factors used in
calculating the emissions from the County’s operations, please see Appendix B: LGOP Standard Report.
In 2006, San Diego County’s government operations greenhouse gas emissions totaled 151,237 metric tons of
CO 2 e. 7 In this report, this number is the basis for comparing emissions across sectors and sources (fuel types), and is
the aggregate of all emissions estimates used in this inventory.
3.1 Summary by Sector
Reporting emissions by sector provides a useful way to understand the sources of San Diego County’s emissions.
By better understanding the relative scale of emissions from each of the sectors, the County of San Diego can more
effectively focus emissions reductions strategies to achieve the greatest emissions reductions. 8
7 This number represents a roll-up of emissions, and is not intended to represent a complete picture of emissions from the County’s
operations. This roll-up number should not be used for comparison with other local government roll-up numbers without a detailed analysis of
the basis for this total. See section 2.3.2 for more detail.
8 The sectors with the largest scale of emissions do not necessarily represent the best opportunity for emissions reductions. Cost,
administration, and other concerns may affect the County’s ability to reduce emissions from any one sector.
