20 chapter 2 Emissions Inventory, Forecasts, and Goals The RPS" will reduce the emissions generated from every kWh of electricity consumed. To calculate the impact of this action, future year emissions factors of the RPS were applied to projected EAU electricity consumption. The emissions reduction from the RPS for 2020 and 2035 is presented in Table 2.4. Table 2.4: Santa Ana Emissions Reduction from the State RPS Year 2020 2035 Reduced Emissions (MTCOze/Year) 182,020 182,762 Vehicle Fuel Efficiency In addition to systematic changes in the electricity grid, large scale changes in the emissions impact of transportation are underway as a result of increasing fuel economy of passenger vehicles from the Pavley regulation S.12 The Pavley regulations are projected to have approximately the same impact on calendar -year fuel economies as national Corporate Average Fuel Economy (CAFE) standards. The emissions reduction from the Pavley regulations for 2020 and 2035 is presented in Table 2.5. Table 2.5: Santa Ana Emissions Reduction from the Pavley Regulations Year 2020 2035 Reduced Emissions (MTCO2e/Year) ...130,308 335,939 Combined Impact The combined impact of the RPS and vehicle efficiency standards will result in a substantial reduction in emissions in Santa Ana. The total reduction from these measures, in addition to the reduction from the existing measures and transportation plans discussed in Chapter 1, is presented in Figure 2.5. It is important to note that this part of the analysis assumes both the RPS and Pavley standards will be fully implemented as planned. As displayed in Figure 2.5, state mandates will play a very important part in moving Santa Ana toward its emissions reduction goals. Two additional factors are important contributors to the emissions reduction seen in the adjusted forecast: the significant actions already undertaken by Santa Ana, and the fact that Santa Ana is mostly built out and has only modest projected increases in population and employment. Other communities, particularly those with higher projected population and employment growth rates, may not have such a favorable adjusted forecast. This adjusted forecast positions Santa Ana to make a substantial reduction below baseline by implementing the new measures described in Chapter 3 of the CAP.
