Decarbonizing California Transportation by 2045 Report to state outlines policy pathways to meet the zero-carbon time crunch

Transportation is the largest source of greenhouse gas emissions in California. In order to achieve the state’s goals of carbon neutrality by 2045 and avoid the worst impacts of climate change, decarbonizing this sector is essential. But such a transition is unlikely to occur rapidly without key policy intervention, according to a new study that included research from the UCLA Luskin Center for Innovation.

A team of transportation and policy experts from the University of California released a report April 21 to the California Environmental Protection Agency (CalEPA) outlining policy options to significantly reduce transportation-related fossil fuel demand and emissions. Those policy options, when combined, could lead to a zero-carbon transportation system by 2045, while also improving equity, health and the economy. A second study, led by UC Santa Barbara, identifying strategies to reduce in-state petroleum production in parallel with reductions in demand, was released simultaneously.

The state funded the two studies through the 2019 Budget Act. The studies are designed to identify paths to slash transportation-related fossil fuel demand and emissions while also managing a strategic, responsible decline in transportation-related fossil fuel supply.

The University of California demand study was conducted by researchers from the UC Institute of Transportation Studies, a network with branches at UC Davis, UC Berkeley, UC Irvine, and UCLA. The UC Davis Policy Institute for Energy, Environment, and the Economy coordinated the report’s policy management, and the UC Davis Center for Regional Change led the study’s equity and environmental justice research.

Bringing about a zero-carbon transportation future will be challenging but not impossible, the report states. Doing so requires urgent actions and a long-term perspective. Importantly, a major upfront investment in clean transportation through incentives and new charging and hydrogen infrastructure will soon pay off in net economic savings to the California economy, with net savings in the next decade growing to tens of billions of dollars per year by 2045.

The report recommends flexible policy approaches that can be adjusted over time as technologies evolve and more knowledge is gained.

“This report is the first to comprehensively evaluate a path to a carbon neutral transportation system for California by 2045,” said Dan Sperling, director of the UC Davis Institute of Transportation Studies. “We find that such pathways are possible but will rely on extensive changes to existing policies as well as introduction of some new policies. The study also prioritizes equity, health and workforce impacts of the transition to zero-carbon transportation.”

Researchers from the UCLA Luskin Center for Innovation led the study’s workforce analysis. Achieving carbon neutrality in California’s transportation sector could create over 7.3 million job-years of employment over the next 25 years, according to the researchers. These jobs would result from “greening” many existing occupations and creating new occupations.

“This presents the state with a golden opportunity to create not only new, high-quality jobs, but also ensure that many existing industries and occupations transition to better practices,” said J.R. DeShazo, director of the Luskin Center for Innovation and professor of public policy.

KEY POLICY STRATEGIES

 Zero emission vehicles: Many of the report’s policy options are centered on a rapid transition to zero-emission vehicles (ZEVs), which is expected to dramatically reduce greenhouse gas emissions and improve local air pollution as the state’s electric grid is also decarbonized.

Light-duty and heavy-duty vehicles are responsible for 70% and 20% of the state’s transportation emissions, respectively. The report suggests a combination of enhanced mandates, incentives, and public charging and hydrogen infrastructure investments to speed the adoption of ZEVs. For medium and heavy-duty vehicles, key policy priorities include increasing the availability of charging stations for long-haul freights, electricity pricing reform to make depot charging more affordable, and priority lanes and curb access for zero-emission trucks, among other possibilities.

Vehicle miles traveled: Even with widespread ZEV use, reducing overall vehicle miles traveled is necessary to reduce traffic congestion and emissions from vehicle manufacturing, and to enhance quality-of-life and land-use benefits related to traffic. The report suggests policies that encourage active, shared and micromobility transportation, telecommuting, and land-use changes that reduce people’s reliance on automobiles and enhance community connectivity.

Fuels: About 86% of transportation fuel is petroleum. Shifting toward low-carbon clean energy requires major investments in electricity and hydrogen. Low-carbon liquid fuels compatible with internal combustion engines will be needed to reduce emissions while the transition to ZEVs progresses, as well as in some specialized applications, like aviation. California can support the needed investments in clean fuels with mandated blending levels, new incentives and credits to stimulate investment in very low-carbon liquid fuels for aviation, shipping and legacy combustion engine vehicles.

Getting to zero: Some residual emissions remain in every scenario examined. The report states that at least 4 million to 5 million metric tons per year of negative emissions capacity (equal to 2.5% of current transportation emissions) is needed by 2045 to counteract those residual emissions. These could come from carbon capture and sequestration projects that pull carbon from the air to store it underground, as well as so-called sequestration by natural or working lands.

BENEFITS

In addition to direct economic benefits beginning around 2030, the transportation decarbonization policies could also lead to health, equity and environmental justice, and workforce and labor benefits.

Health: Transportation is a major cause of local air pollution and contributes to climate change. Particulate matter harms lungs and hearts, while nitrogen oxide compounds contribute to ozone pollution and other health impacts. The report found that cleaner heavy-duty vehicles would significantly reduce pollution in many of the state’s most vulnerable communities. The health benefits of reducing local pollution will grow with the deployment of clean transportation technologies and could translate to more than $25 billion in savings in 2045.

Equity and environmental justice: Transportation in California carries a legacy of inequity and damage to disadvantaged communities. These communities often lack quality public transportation or viable transportation choices. Highways have been built with little consideration for displacement, and many communities of color have been divided by freeways, perpetuating historic segregation policies like redlining. The report identifies options that prioritize equity in transportation investments and policies.

For example:

  • Continue to support electric vehicle incentives targeted to lower-income buyers and underserved communities, including used vehicles.
  • Prioritize deploying electric heavy-duty vehicles in disadvantaged communities and magnet facilities such as commercial warehouses in those communities.
  • Support transit and zero-emission services and charging stations in disadvantaged communities. This can help reduce vehicle miles traveled and increase accessibility while avoiding displacement.
  • Avoid siting non-renewable fuel production facilities in disadvantaged communities, engage communities disproportionately affected by transportation sector emissions in decision-making concerning the siting of new infrastructure and investments associated with achieving carbon neutrality, and continue to carefully monitor and control local pollutants.

“We must confront the legacy of the lack of public and private investment where Black, indigenous and people of color live and work,” said Bernadette Austin, acting director of the UC Davis Center for Regional Change. “This report identifies ways to strategically invest in sustainable infrastructure while intentionally avoiding disruptive and damaging infrastructure in our most vulnerable and disadvantaged communities.”

Workforce: The transition to a carbon-neutral transportation system will disrupt jobs in some sectors while creating new jobs in others, like clean vehicle manufacturing and electric and hydrogen fueling infrastructure. The report suggests that California prioritize the needs of impacted workers. In addition, wherever ZEV-related industry expansion creates quality jobs, state policy should focus on creating broadly accessible career pathways.

Economy: The transition to ZEVs is expected to generate savings for consumers and the economy well before 2045. Within the next decade, the cost of owning and operating ZEVs is projected to drop below that of a conventional gasoline or diesel vehicle. That is because battery, fuel cell and hydrogen costs will continue to decline; electricity costs will be much less than petroleum fuel costs; and maintenance costs of ZEVs will be less. These savings can be invested elsewhere by households and businesses.

State Risks Falling Short of Carbon Reduction Benchmarks Unless It Puts Equity First

To reach Gov. Gavin Newsom’s net-zero emission vehicle goal by 2035, officials should put equity goals at the forefront of the state’s strategy or risk falling short of benchmarks and worsening community disparities, according to new research by the UCLA Luskin Center for Innovation. The report highlights challenges and opportunities amid California’s push to cut carbon emissions and local air pollution. The study comes as state lawmakers consider Newsom’s 2021-22 budget proposal, which includes $1.5 billion toward zero-emission vehicle efforts. “As California transitions to a zero-emission transportation system, it needs a robust and multifaceted agenda for equity-centered clean transportation policies,” said JR DeShazo, director of the Luskin Center for Innovation. “Pursuing this agenda of recommendations elevates and builds equity into the next generation of California’s clean transportation policies.” The study, commissioned by the Los Angeles Business Council, underscores that previous clean transportation policies did not equally benefit all Californians. Low-income communities hit hardest by pollution have been largely left behind in the green transition, and disparities threaten to impact communities of all income levels through climate change. The greatest hurdle to meeting environmental goals appears to be directing clean vehicles to moderate- and low-income drivers who are more likely to own older, emissions-heavy vehicles. Researchers recommend lowering the purchase price of new and used zero-emission vehicles, subsidizing vehicle financing, and reducing the cost of charging infrastructure and the electricity or fuel itself. A key recommendation is for zero-emission fleets to be deployed first to disadvantaged communities.


UCLA Helps Civic Leaders Address ‘Vexing Issues’ During Annual Mayoral Summit

The setting was virtual this time, but UCLA again figured prominently when the Los Angeles Business Council convened a who’s who of California elected officials and civic leaders for its annual Mayoral Summit on Housing, Transportation and Jobs, an event that UCLA has co-hosted for 18 of its 19 years. “This event is near and dear to our hearts,” Chancellor Gene Block said in welcoming remarks. “As a public institution with a deeply rooted service mission, we view it as our obligation to help address the vexing issues facing our city.” Academic research figured prominently in the daylong event presented in partnership with the UCLA Ziman Center for Real Estate and the UCLA Luskin Center for Innovation directed by JR DeShazo, professor of public policy. He moderated a panel focusing on how to promote zero-emission vehicles in an equitable manner, noting that California’s policy investments have brought low-emission vehicles to 10% of sales, a notable accomplishment. “But we have failed miserably to make those policies beneficial to our low-income communities and communities of color,” DeShazo said. Richard Ziman, who is founding chair of the Los Angeles Business Council, opened the virtual summit, and Stuart Gabriel, professor of finance and director of the Ziman Center, led a session on economic recovery efforts. Jacqueline Waggoner, Miguel A. Santana and Michael Mahdesian of the UCLA Luskin School of Public Affairs Board of Advisors also spoke, as did public officials that included Los Angeles Mayor Eric Garcetti, Senate President pro Tempore Toni G. Atkins and Assembly Speaker Anthony Rendon.
