Actions Evaluation: Actions that are Cost-Effective and Can Significantly Reduce Greenhouse Gas Emissions No single action has a greater impact on reducing greenhouse gas emissions than CR-4.2/4.3, which gradually charges the right price for every on-street space. This Parking action yields the highest annual emissions reductions, the greatest cumulative reductions and is the most cost-effective. In fact, because of low capital and operating costs and its revenue-generating nature, this action has a net-positive financial impact (its revenues more than make up for its costs). Expected to significantly alter behavior through less driving, it yields significant community benefits as well.
Packages Evaluation Matrix Metrics
Package A: Capital-intensive
Package B: Program-intensive
Package C: Do Everything (Packages A + B + more parking reform)
Description
Includes all the capital-intensive actions (including all transit, all active transportation and some parking actions) if we were to fully implement them by 2050
Includes all program-intensive actions (including all TDM, most parking actions, and all community programs actions) if we were to fully implement them by 2050
Includes both capital and program-intensivey actions from both Packages A and B, plus more intense parking reform.

The transit improvements that come from Muni Forward, CR-1.5, are exactly the kind that beget important community benefits, which range from air quality to economic activity to travel experience. Such improvements transform the streetscape to improve not only transit but active transportation as well. Though the emissions reduced per dollar spent may not compare with a low-cost programmatic action, the overall benefits of transit actions make it clear these are dollars well spent.

The most substantial action of the Active Transportation strategy, expanding the network with new bikeways and Slow Streets, CR-2.4, is also the most cost-effective. Working with members of the community to plan how and where new infrastructure will go increases the likelihood that more San Franciscans will choose to walk, bike and roll. Importantly, this action is projected to have the highest potential community benefit, advancing racial equity alongside public health and safety.

Community Transportation Planning, CR-6.1, would not generate revenue, but with a relatively low cost and high annual emissions reduction potential, it would be very cost-effective. By advancing Community-Based Transportation Plans and further resourcing community outreach, this action is a critical way to advance racial equity and promote the shifts to low-carbon modes that other strategies are investing in. The installation of new EV charging stations on city property, CR-5.1, is also a very cost-effective strategy for bringing down greenhouse gas emissions, with a significant potential for annual reductions. At the same time, an action centered on EVs does not yield many community benefits and would therefore need to be paired with other actions that can help advance racial equity and safety.
