Future GHG Emissions Forecasts <br /> <br />Pleasanton Climate Action Plan Update 41 <br />Electricity Emissions <br />Between 2017 and 2045, electricity emissions from residential and nonresidential buildings in <br />Pleasanton are assumed to decrease from 59,181 MT CO2e to 0 MT CO2e in 2045 despite steady <br />growth in Pleasanton’s population and employment levels due to the adoption of SB 100 and the <br />renewable portfolio standard. Electricity emissions are expected to stay at 0 MT CO2e in 2050 as well. <br />It is currently not clear if PG&E’s current plan to reach carbon neutral electricity by 2045 includes the <br />use of offsets. Future work will need to be done if so to ensure no double counting occurs between <br />PG&E and Pleasanton’s efforts to reach carbon neutral emissions. <br />Emissions from future electricity use were forecasted by projecting anticipated growth in residential <br />and commercial sectors and multiplying by expected electricity emission factors. Anticipated growth in <br />the residential sector was projected as a function of population growth within Pleasanton while <br />commercial sector electricity use was projected as a function of employment projections. Legislative <br />adjustments included in the electricity sector forecast include RPS of 60 percent by 2030 and 100 <br />percent GHG-free by 2045. Additionally, Title 24 building code efficiency increases for the 2019 code <br />cycle were applied to all new growth within the city. The methodologies for the electricity sector which <br />were forecasted in the adjusted scenario are summarized in Table 24 and Table 25. <br />Table 24 Electricity Sector Adjusted Forecast Scenario Methodology <br />Source Category <br />Forecasted Activity Data <br />(Scaling Factor) Emission Factor <br />Applied Legislative <br />Reductions <br />Residential Electricity Population growth in <br />Pleasanton <br />Assumes an electricity mix of 44 <br />percent, 60 percent, and 100 percent <br />GHG-free by 2025, 2030, and 2045, <br />respectively, for PG&E emission factors <br />per RPS requirements. <br />Title 24 standards for new <br />construction in 2019 (53 <br />percent residential, 30 <br />percent commercial), RPS <br />requirements <br />Commercial & <br />Industrial Electricity <br />Employment growth in <br />Pleasanton <br />RPS: Renewable Portfolio Standard; GHG: greenhouse gas; PG&E: Pacific Gas and Electric <br /> <br /> <br /> <br />
