For programs which are classified as enabling, staff is generally not able to attribute specific carbon savings with certainty. Background During the Our Climate Future work session, Councilmember Cunniff asked about the carbon savings from specific programs. There are several levels at which this question can be answered. Staff calculate carbon reductions for programs which have direct reductions in the use of grid electricity and natural gas. The calculations are based upon the carbon accounting principles for grid electricity or natural gas reductions and examples of this approach include energy efficiency and solar programs. The electricity savings and lifecycle cost per kilowatt-hour of Utilities program portfolio are reported annually in the Energy Policy update. For the purposes of this memo, 2019 savings have been converted to carbon units (metric tons) and also include the distributed renewable programs. Savings are reported for the annual results and for the cumulative effects since 2005 (as savings continue for the life of the measure). See Figures 1 and 2. For programs which are classified as enabling, staff is generally not able to attribute specific carbon savings with certainty. One example of this type of programs is the Shift campaign. However, enabling programs are often a driver for increased participation in the direct programs. Updated forecast impacts for a wide range of strategies (including for waste and mobility) will be a part of the pending Next Moves analysis. Staff also uses the annual community carbon inventory process to calibrate and review the drivers for changes in the inventory. Examples of these drivers include population growth, weather and program savings. Figure 3 shows this information for electricity based on the 2018 inventory.

This will be updated in Q1 2021 based on the 2019 inventory and will include industrial process and product use (IPPU) emissions.
