This report highlights equity-oriented micromobility programs that provide access to shared bicycles and scooters in five US cities. Drawing from interviews, the report offers pioneering models and actionable steps for government agencies, micromobility providers, and community-based organizations to expand access and affordability among low-income and black, indigenous, and people of color travelers and improve infrastructure in their communities.

California will require a transformation of its light-duty vehicle fleet in order to meet statewide air quality and climate change goals. As a percentage of household earnings, lower-income populations face disproportionate costs to maintain and operate a vehicle. Optimally priced incentives and financing options can therefore promote household economic well-being while generating broader environmental benefits. To do so, financial incentives should be designed to accelerate the retirement and replacement of older, high-polluting vehicles and increase the adoption of clean vehicles. Yet several challenges persist in enabling low- and moderate-income households to adopt near-zero and zero-emission vehicles in California.
This report, based on an LCI survey of 1,604 low- and moderate-income households, assesses current policies and informs future strategies intended to improve clean vehicle access and use by low- and moderate-income households in California. The results help identify effective policy approaches to improve access to, and adoption of, clean vehicles.

The nonprofit organization Valley Clean Air Now (Valley CAN) operates multiple longstanding
clean vehicle programs to reduce emissions from older vehicles in the San Joaquin Valley (SJV) of California, a region with many disadvantaged communities with environmental justice concerns. Since 2015, Valley CAN has piloted and now operates the Clean Cars 4 All program (also known as Drive Clean in the San Joaquin), which offers clean vehicle incentives to low- to moderate-income households.
This evaluation by LCI utilizes several datasets to track program progress over the nine-month period of October 2018 through June 2019, a time when Electrify America provided enhanced funding for Valley CAN to accelerate the reach and pace of the program in the SJV. This initial assessment considers four stages of impact experienced by SJV residents via the enhanced funding: awareness, involvement, engagement, and vehicle acquisition. Even in this short period, we observe notable positive impacts of ELAM funding in all four stages.

LCI researchers analyzed data from the San Joaquin Valley’s smog test and vehicle repair program known as Tune In & Tune Up. We found that the program is a model that other regions could use to efficiently reduce emissions from cars and other light-duty vehicles while addressing the mobility needs of low-income households. It is one of the first transportation programs in the nation premised on jointly achieving efficiency, equity and environmental objectives, and is now informing a grassroots outreach pilot program, led by the Liberty Hill Foundation, bringing clean vehicle, clean energy, and financial assistance programs to low-income households in Los Angeles County.

The Enhanced Fleet Modernization Program (EFMP) Plus-Up pilot program is helping hundreds of low-income drivers get out of old, inefficient vehicles and into cleaner, more efficient cars. This LCI report describes how the EFMP Plus-Up pilot was implemented in the two air districts chosen for the pilot phase, the San Joaquin Valley Air Pollution Control District and South Coast Air Quality Management District, during the first year of program operation. The research is informing the state’s expansion of the program (now renamed Clean Cars 4 All) to other parts of California.
A previous study and article from LCI informed the design of the EFMP Plus-Up pilot. That research found that policymakers could facilitate more emission reductions by strategically linking vehicle purchase incentives with vehicle retirement incentives, which consequently the California Air Resources Board designed EFMP Plus-Up to do in support of low- to moderate-income households.

These two reports explore barriers and opportunities to PEV adoption for residents of apartments and other multi-unit dwellings, using the South Bay subregion and the Westside Cities subregion of Los Angeles County as case studies. The lessons learned are relevant to other areas as well. The studies were supported by the Southern California Association of Governments and the California Energy Commission.

More Californians can now afford clean vehicles, in part thanks to research involving the LCI. The researchers assessed the performance of alternative rebate designs for PEVs and compared these alternatives in terms of cost-effectiveness and equity. They found that providing progressive rebate levels based on consumer income levels would provide benefits within those performance criteria. These findings helped inform the adoption of California’s progressive rebate system in which low- and moderate-income drivers receive an additional $3,000 to $6,500 in financial incentives to purchase a clean vehicle. Additionally, income rules for most rebates limit eligibility to households with less than $500,000 in annual income.

This article evaluates the effectiveness of current clean vehicle incentive policies in the U.S. and makes recommendations for improvement. The associated study found that policymakers could facilitate more emission reductions by strategically linking vehicle purchase incentives with vehicle retirement incentives (e.g., cash for clunkers). This is because purchase incentives alone do not influence the type, timing, and pollution intensity of the retirement vehicle, a decision that is a critical determinant of emissions. Aligned with our recommendations, in 2015, the California Air Resources Board introduced the Enhanced Fleet Modernization Program (EFMP) Plus-Up pilot program (as approved by Assembly Bill 118) to better integrate vehicle retirement and replacement incentive programs in support of low- to moderate- income households.
