Scope 2: Indirect emissions associated with the consumption of electricity and steam that are purchased from an outside utility. Scope 3: All other emissions sources that hold policy relevance to the local government that can be measured and reported. This includes all indirect emissions not covered in Scope 2 that occur as a result of activities within the operations of the local government. Sources over which the local government does not have any financial or operational control over would be accounted for here. Scope 3 emission sources include (but are not limited to) tailpipe emissions from employee commutes, employee business travel, and emissions resulting from the decomposition of government-generated solid waste. Table 2.3 Inventoried Emission Sources by Scope 8 Scope 1 Scope 2 Scope 3 Fuel consumed to heat/cool facilities Purchased electricity consumed by facilities Solid waste generated by government operations Fuel consumed for vehicles and mobile equipment Purchased electricity consumed by electric vehicles Fuel consumed for employee vehicles used for commuting Fuel consumed to generate electricity Purchased steam for heating or cooling facilities Leaked refrigerants from facilities and vehicles Leaked/deployed fire suppressants Wastewater decomposition and treatment at a municipal wastewater treatment plant Solid waste in government landfills 2.3.2 Double Counting and Rolling Up Scopes Many local governments find it useful for public awareness and policymaking to use a single number (a “roll-up” number) to represent emissions in its reports, target setting, and action plan. A roll-up number allows local governments to determine the relative proportions of emissions from various sectors (e.g., 30 percent of rolled up emissions came from the vehicle fleet). This can help policymakers and staff identify priority actions for reducing emissions from their operations. For these reasons, this report includes a roll-up number as the basis of the emissions analysis in this inventory. This roll-up number is composed of direct emissions (Scope 1), all emissions from purchased electricity (Scope 2), and indirect emissions from employee commutes and government-generated solid waste (Scope 3). 8 This only represents a list of emissions that were inventoried for the Silicon Valley Climate Protection Partnership inventories. This is not meant to be a complete list of all emissions that can be inventoried in a government operations inventory. 2005 Daly City Government Operations Greenhouse Gas Emissions Inventory 12
While this report uses a standard roll-up number, these numbers should be used with caution, as they can be problematic for three reasons: First, a roll-up number does not represent all emissions from Daly City’s operations, only a summation of inventoried emissions using available estimation methods. Reporting a roll-up number can be misleading and encourage citizens, staff, and policymakers to think of this number as the local government’s “total” emissions. Therefore, when communicating a roll-up number it is important to represent it only as a sum of inventoried emissions, not as a comprehensive total. Second, rolling up emissions may not simply involve adding emissions from all sectors, as emissions from different scopes can be double-counted when they are reported as one number. For example, if a local government operates a municipal utility that provides electricity to government facilities, these are emissions from both the power generation and facilities sectors. If these sectors are rolled up into a single number, these emissions are double counted, or reported twice. For these reasons, it is important to be cautious when creating a roll-up number to avoid double counting; the roll-up number used in this report was created specifically to avoid any possible double counting. Third, local governments often wish to compare their emissions to those of other local governments. But it is very difficult to use a roll-up number as a common measure between local governments, for a number of reasons. First, as of now there is no national or international standard for reporting emissions as a single roll-up number. In addition, local governments provide different services to their citizens, and the scale of the services (and thus the emissions) is highly dependent upon the size of the jurisdiction. For these reasons, comparisons between local government roll-up numbers should not be made without significant analysis of the basis of the roll-up number and the services provided by the local governments being compared. 2005 Daly City Government Operations Greenhouse Gas Emissions Inventory 13
