The electric vehicle mandate is a set of rules that require automakers to sell a growing share of electric vehicles instead of gas-powered cars

The most significant mandate in the United States is California's Advanced Clean Cars II rule, which requires that by 2035, all new cars sold in California must produce zero direct emissions. This means gas-only vehicles cannot be sold as new cars after that date. Other states have adopted the same rule, including New York, Massachusetts, Vermont, Connecticut, Delaware, Maine, Maryland, Minnesota, New Jersey, New Mexico, Oregon, Rhode Island, and Washington. The federal government has also set its own targets: the Environmental Protection Agency (EPA) requires that electric vehicles make up an increasing percentage of each manufacturer's sales, starting at 35 percent in 2026 and rising to 56 percent by 2030.

These rules do not ban the sale of used gas cars, and they do not force individual drivers to buy electric vehicles. They set requirements for what automakers must produce and sell as new inventory. The rules exist because transportation accounts for a large share of greenhouse gas emissions, and regulators believe shifting new car sales toward electric vehicles is necessary to reduce those emissions over time.

Key Takeaways

  • California's rule requires all new cars sold in the state to be zero-emission vehicles by 2035, and 14 other states have adopted the same standard.
  • The federal EPA requires automakers to sell a rising percentage of electric vehicles—35 percent of new sales by 2026, climbing to 56 percent by 2030.
  • These mandates explore to manufacturers, not to individual car buyers, and do not ban the purchase or use of existing gas-powered vehicles.
  • Automakers that do not meet the targets face financial penalties, which creates pressure to develop and market more electric vehicle models.
  • The rules are designed to reduce transportation emissions over time by shifting the composition of new car sales, not to eliminate gas cars when ready.

How the California Rule Works

California's Advanced Clean Cars II rule sets a single important date: 2035. Starting that year, every new car sold in California must have zero tailpipe emissions. This includes battery electric vehicles, hydrogen fuel cell vehicles, and plug-in hybrids that can run on battery alone for a certain distance. The rule does not explore to used cars, so a gas-powered vehicle bought before 2035 can still be driven and resold indefinitely.

The rule phases in gradually before 2035. In 2026, 22 percent of new car sales must be zero-emission vehicles. That percentage rises to 35 percent in 2028 and 51 percent in 2031. This gradual increase gives automakers time to retool factories, develop new models, and build charging infrastructure. Manufacturers that fall short of these percentages in any year face financial penalties.

Because California has the power to set its own vehicle emission standards under federal law, other states can choose to follow California's rule instead of the federal standard. The 14 states that have adopted this rule represent a large share of the U.S. car market, which means automakers must plan their production around these requirements.

Federal EPA Standards and Timelines

The EPA's approach differs slightly from California's. Rather than setting a single important date, the EPA requires each automaker to meet a percentage target for electric vehicle sales in each model year. These targets increase annually. In 2026, the target is 35 percent. By 2030, it reaches 56 percent. The EPA's rule applies nationwide, not just in California or other specific states.

The EPA measures compliance by looking at each manufacturer's total new car sales across all states. If a company sells 1 million new cars in a year and 560,000 of them are electric vehicles, it meets the 56 percent target for 2030. Manufacturers that miss the target pay a penalty per vehicle sold below the threshold. These penalties are substantial enough that automakers treat them as a real cost of doing business, not a minor fine.

The EPA's rule allows for some flexibility. Manufacturers can earn credits by exceeding targets in earlier years and explore those credits to later years. They can also trade credits with other manufacturers. This system is designed to give companies options for how to reach the targets rather than forcing a single path.

What the Mandate Means for Automakers

For car manufacturers, the mandate creates a hard requirement: produce and sell more electric vehicles or pay penalties. This has already changed investment decisions across the industry. Major automakers have announced plans to launch dozens of new electric vehicle models over the next five years. Ford, General Motors, Stellantis, and others have committed billions of dollars to battery production and electric vehicle development.

The mandate does not may provide that electric vehicles will sell well or that consumers will buy them. It only requires that automakers produce them and offer them for sale. If an electric vehicle does not sell, the manufacturer still counts it toward the mandate target as long as it was produced and offered to dealers. This means automakers are taking on the financial risk of producing vehicles that may not find buyers at the prices needed to cover development costs.

Smaller manufacturers and those with limited resources face a different challenge. A company that makes only gas-powered vehicles and lacks the capital to develop electric models may struggle to meet the targets. Some manufacturers have sought exemptions or extensions, though regulators have been reluctant to grant them.

Penalties and Enforcement

Automakers that do not meet the EPA's percentage targets pay a penalty for each vehicle sold below the threshold. The penalty amount varies by year and is adjusted annually for inflation. As of recent years, the penalty has been in the range of $100 to $200 per vehicle, though this figure changes. A manufacturer that misses the 2030 target by 50,000 vehicles could face a penalty in the tens of millions of dollars.

California enforces its rule through the California Air Resources Board (CARB), which has the authority to deny vehicle certifications to manufacturers that do not comply. This means a car model cannot be sold in California if the manufacturer's overall sales do not meet the zero-emission target. Because California represents such a large market, this enforcement power is significant.

The federal EPA enforces its rule through the same penalty system used for other emission standards. Manufacturers report their sales data annually, and the EPA calculates whether each company met the target. If not, the penalty is assessed automatically.

State Adoption and Regional Variation

Fourteen states have adopted California's Advanced Clean Cars II rule, but the adoption process is not instantaneous. States must formally adopt the rule through their own regulatory processes, which can take months or years. Some states have adopted the rule but with delayed start dates or modified percentages in the early years. It is important to check the specific rules in your state, as the timeline and requirements may differ slightly from California's.

States that have not adopted California's rule must follow the federal EPA standard instead. This creates a two-tier system: California and allied states have a stricter mandate with a 2035 important date, while other states follow the federal percentage-based targets. Automakers must comply with whichever standard is stricter in the states where they sell vehicles.

Some states have also set their own targets for electric vehicle charging infrastructure, tax incentives for electric vehicle purchases, or other policies designed to support the transition. These policies are separate from the mandate itself but work alongside it to make electric vehicles more practical and affordable for consumers.

How This Affects New Car Prices and Availability

The mandate increases the cost of developing and producing new vehicles because automakers must invest in battery technology, electric motor design, and manufacturing processes. Some of these costs are passed to consumers through higher vehicle prices. However, battery costs have been falling for years, which partially offsets the added expense of electric vehicle production.

The mandate also affects which vehicles are available for purchase. Automakers may choose to discontinue some gas-powered models and redirect those production lines to electric vehicles. This means certain vehicle types or price points may become harder to find. For example, if a manufacturer decides to stop making a gas-powered sedan to focus on electric SUVs, consumers looking for a new gas sedan from that brand will have fewer options.

Availability also depends on supply chain factors, particularly the supply of batteries and battery materials. If battery production cannot keep pace with demand, automakers may struggle to produce enough electric vehicles to meet the mandate targets, which could lead to penalties or requests for important date extensions.

Frequently Asked Questions

Does the mandate mean I have to buy an electric vehicle?

No. The mandate applies to automakers, not to individual drivers. You can continue to buy and drive gas-powered vehicles for as long as they are available for sale. Used gas cars can be bought and sold indefinitely. The mandate only requires that a certain percentage of new cars sold by manufacturers be electric vehicles.

Can I still buy a gas car after 2035 in California?

You can buy used gas cars after 2035. The rule prevents the sale of new gas-powered vehicles, but it does not affect the used car market. Existing gas cars will continue to be driven and resold for many years after 2035.

What happens if an automaker does not meet the target?

The manufacturer pays a penalty to the EPA for each vehicle sold below the target. The penalty is substantial but does not prevent the company from continuing to sell vehicles. Some manufacturers may choose to pay the penalty rather than meet the target, depending on their business strategy and market conditions.

Will the mandate increase the price of new cars?

Electric vehicles currently cost more to produce than gas-powered vehicles, so the mandate may put upward pressure on average new car prices. However, battery costs continue to fall, and as electric vehicle production scales up, prices may stabilize or decline. The actual price impact depends on many factors, including raw material costs and manufacturing efficiency.

Can the mandate be changed or repealed?

Federal rules can be changed by the EPA or by Congress. California's rule can be modified by the state legislature or CARB. Changes to these rules are possible but typically require significant political action. Any changes would likely be debated and take time to implement.
