In September 2020, California Governor Gavin Newsom made headlines when he announced an ambitious plan to ban the sale of new gasoline-powered cars in the state by 2035. This move was hailed as a significant step in the global effort to combat climate change and reduce greenhouse gas emissions. However, a recent study has shed light on the potential economic impact of this policy, revealing that it could cost California taxpayers up to $20 billion.

The study, conducted by researchers at the University of California, Berkeley, and released by the nonpartisan think tank Center for Policy Initiatives, examined the potential costs associated with transitioning to a fully electric vehicle (EV) fleet in California. The findings are the first of their kind to comprehensively analyze the financial implications of the state's ambitious goal of phasing out gas-powered cars.

Analyzing the Costs

The researchers estimated that the state's plan to ban the sale of new gasoline-powered cars by 2035 would lead to a significant increase in the demand for electric vehicles. This surge in demand would result in a need for substantial investments in EV infrastructure, including charging stations and grid upgrades, to support the transition. Additionally, the study highlighted the costs associated with incentivizing consumers to purchase EVs, as well as the potential challenges of effectively managing and recycling the batteries used in these vehicles.

The researchers concluded that these investments and incentives could ultimately amount to a price tag of up to $20 billion for California taxpayers. This substantial figure has raised concerns about the feasibility and affordability of the state's plan to transition to an all-electric vehicle fleet within the next 15 years.

Potential Impact on Taxpayers

The potential $20 billion cost to taxpayers has sparked a heated debate among policymakers, industry leaders, and environmental advocates. Proponents of the gas car sale ban argue that the long-term benefits of reducing emissions and combating climate change outweigh the initial financial burden. They contend that the transition to electric vehicles will create new jobs, drive innovation, and lead to significant environmental and public health benefits.

On the other hand, opponents of the ban have raised concerns about the cost and practicality of implementing such a significant policy change. They argue that the $20 billion price tag could strain the state's budget, potentially leading to higher taxes or reduced funding for other critical infrastructure and public services. Additionally, some critics have questioned whether the current EV technology and infrastructure are advanced enough to support a widespread transition away from gasoline-powered vehicles.

Challenges and Considerations

The findings of the study have underscored the need for careful consideration of the economic implications of transitioning to an all-electric vehicle fleet. As California continues to pursue its ambitious climate goals, policymakers will need to address several key challenges to ensure a successful and cost-effective transition.

Infrastructure Investments

One of the most significant challenges highlighted by the study is the need for substantial investments in EV infrastructure. This includes expanding the network of charging stations to accommodate the growing number of electric vehicles on the road. The cost of building and maintaining this infrastructure will be a critical factor in determining the overall financial impact of the transition to EVs.

Consumer Incentives

To encourage consumers to make the switch to electric vehicles, the state will likely need to provide significant incentives, such as rebates and tax credits, to offset the higher upfront costs of EVs compared to traditional gasoline-powered cars. The cost of these incentives will add to the overall financial burden of the transition and will need to be carefully managed to ensure they are effective in driving EV adoption.

Battery Recycling and Disposal

As the demand for electric vehicles increases, so too will the need to manage and recycle the batteries used in these vehicles. This presents a significant logistical and financial challenge, as the current infrastructure for battery recycling is limited. Addressing this challenge will require substantial investments in recycling facilities and technologies, adding to the overall cost of the transition to EVs.

Grid Upgrades

The widespread adoption of electric vehicles will place increased demand on the state's electrical grid. To support this demand, significant upgrades and modernization of the grid will be necessary. These upgrades can come with substantial costs, and careful planning will be essential to ensure the grid can effectively support a fully electric vehicle fleet.

Policy Implications

The $20 billion cost estimate has significant implications for policymakers in California and beyond. As states and countries around the world grapple with the challenge of reducing greenhouse gas emissions from the transportation sector, the lessons learned from California's experience will be crucial in shaping future policy decisions.

The findings of the study serve as a reminder of the importance of carefully evaluating the economic implications of ambitious climate goals. While the environmental benefits of transitioning to electric vehicles are clear, the costs and challenges associated with such a transition cannot be overlooked. Policymakers will need to consider these factors when developing and implementing policies aimed at reducing emissions from the transportation sector.

Additionally, the study highlights the need for collaboration between government, industry, and academia to develop effective strategies for managing the economic and logistical challenges of transitioning to a fully electric vehicle fleet. By working together, stakeholders can identify innovative solutions and reduce the financial burden of this transition on taxpayers.


The study's findings have sparked a critical conversation about the economic implications of California's plan to ban the sale of new gasoline-powered cars by 2035. The potential $20 billion cost to taxpayers raises important questions about the feasibility and affordability of transitioning to an all-electric vehicle fleet within the next 15 years.

While the environmental benefits of reducing emissions from the transportation sector are significant, the financial challenges associated with this transition cannot be ignored. Policymakers and stakeholders will need to work together to address the infrastructure, consumer incentives, battery recycling, and grid upgrade challenges to ensure a successful and cost-effective transition to electric vehicles.

In the coming years, California's experience will serve as a valuable case study for other states and countries seeking to reduce emissions from the transportation sector. By carefully evaluating the economic implications and developing effective strategies, policymakers can ensure that ambitious climate goals are achieved in a manner that is both environmentally and economically sustainable.
