\u201cA recent survey<\/a> by the American Automobile Association (AAA) found that only 16% of potential buyers were either \u201clikely\u201d or \u201cvery likely\u201d to buy a fully electric vehicle as their next car, \u2026 down from 25% in 2022 and was the lowest level of EV interest recorded by AAA surveys since 2019.\u201d<\/p>\n<\/blockquote>\n\n\n\n

The road to adoption of Zero Emissions Vehicles (ZEVs) is growing steeper. For over two decades, states used incentives and mandates to try to force a transition from gasoline vehicles to ZEVs. But softening market demand, shifting federal policies, and poor economics threaten to halt the ZEV revolution in the United States.<\/p>\n\n\n\n

Zero Emissions Vehicles are cars and trucks that produce no tailpipe emissions. These are either electric vehicles (EVs) or hydrogen vehicles. California is the only state with a significant number of hydrogen cars, but its hydrogen car population is declining, so ZEVs mean EVs in practice.<\/p>\n\n\n\n

Air pollution reached hazardous levels in the 1950s. The expanding population and automobile fleet in Los Angeles generated recurring episodes of smog, reducing visibility, causing nausea, and burning eyes. As a child, I recall having our car windows coated by pollutants from the steel mills of Gary, Indiana during a drive-by, forcing us to stop to clean our windshield.<\/p>\n\n\n\n

To combat worsening air pollution, all states enacted legislation by 1970. Congress passed the Clean Air Act in 1963 and established the Environmental Protection Agency (EPA) as part of the Clean Air Act of 1970.<\/p>\n\n\n\n

Early vehicle pollution regulations were enormously successful eliminating harmful vehicle exhaust. Unleaded gasoline, catalytic converters, and particulate filters dropped volatile organic compound emissions<\/a> per mile by 98 percent from 1970 to 2023. Carbon dioxide (CO2) and water vapor remain the only significant gases exhausted from today\u2019s gasoline vehicles.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

With hazardous emissions all but eliminated, the primary purpose of ZEV regulations is to force a transition to electric vehicles to reduce greenhouse gas emissions, primarily CO2. The first Zero Emissions Vehicle regulation was adopted<\/a> by California in 1990. Today, 22 states have ZEV regulations<\/a>, many requiring up to 100 percent of new car sales to be EVs by a future date, such as 2050. But the US ZEV transition has stalled due to three factors\u2014weakening demand, changing federal policies, and poor economics.<\/p>\n\n\n\n

The US market share<\/a> of Battery Electric Vehicles (BEVs) in the second quarter of 2025 was only 7 percent of car sales, down from over 8 percent during last November, December, and January. BEV share in the US has been flat since spring 2023.<\/p>\n\n\n\n

A recent survey<\/a> by the American Automobile Association (AAA) found that only 16% of potential buyers were either \u201clikely\u201d or \u201cvery likely\u201d to buy a fully electric vehicle as their next car, while 63% were \u201cunlikely\/very unlikely.\u201d The \u201clikely\/very likely\u201d category was down from 25% in 2022 and was the lowest level of EV interest recorded by AAA surveys since 2019.<\/p>\n\n\n\n

Under President Joe Biden, the federal government provided a wide array of tax credits, subsidies, and loans for EVs. President Donald Trump shifted<\/a> policy efforts to \u201celiminate the electric vehicle mandate,\u201d including ending subsidies and mandates and rolling back state ZEV regulations.<\/p>\n\n\n\n

Congress passed the One Big Beautiful Bill Act and President Trump signed it this month. The act eliminates<\/a> tax credits for purchasing a new EV (up to $7,500) and a used EV (up to $4,000), effective September 30 of this year. Loss of tax credits will increase the cost of EVs, likely forcing US EV market share below 7% by the end of this year.<\/p>\n\n\n\n

The 1970 Clean Air Act assigned<\/a> responsibility for air pollution to the EPA but allowed the EPA to grant waivers to states for regulations that were stricter than federal limits. California has received<\/a> more than 100 waivers under the Clean Air Act. Other states are allowed to adopt California pollution regulations. State ZEV standards require a waiver from the EPA.<\/p>\n\n\n\n

But in June, President Trump signed three resolutions that rescinded<\/a> California\u2019s ZEV mandates. The principal resolution revoked the Clean Air Act waiver to California that was granted during the Biden administration. The waiver had allowed the state\u2019s Advanced Clean Cars II regulation, which mandated that all light vehicles sold in California by 2035 must be zero emissions. The waiver also allowed Colorado, Maryland, Massachusetts, New Jersey, New York, Pennsylvania, Washington, and other states to adopt California\u2019s regulations.<\/p>\n\n\n\n

Another resolution signed by President Trump rescinded the EPA waiver that authorized California\u2019s Advanced Clean Fleets regulation, which began January 2024. The ACF forced new heavy-duty trucks registered in California to be zero-emissions. Prior to the Trump rollback, trucking companies wrestled with severe cost, weight, and vehicle range issues of electric trucks mandated by the regulation.<\/p>\n\n\n\n

California immediately sued<\/a> the federal government to restore the EPA waivers and revive ZEV mandates. But without a legal victory, state ZEV mandates are dead in the US, at least until a new federal administration is elected.<\/p>\n\n\n\n

Without federal tax credits and state ZEV mandates, vehicle purchasers face the full brunt of the unfavorable economics of EVs.  Advantages of EVs include the ability to charge at home and lower cost of operation for small daily travel distances. But their economic disadvantages include higher purchase prices, heavier vehicle weight, shorter driving range, higher maintenance and repair costs, higher insurance costs, and rising licensing fees.<\/p>\n\n\n\n

The average US electric car purchase price<\/a> in May was $57,734, about 17% higher than the average price for a gasoline car. Cancellation of the EV purchase tax credit will push this difference to over 20%. Electric trucks and buses are two to three times as expensive as diesel alternatives.<\/p>\n\n\n\n

Thousand-pound EV car batteries are needed for a driving range approaching that of internal combustion engine (ICE) cars. As a result, EVs tend to be about 50% heavier than ICE cars. The 2024 Chevy Silverado EV weighs<\/a> over 8,000 pounds, a four-ton pickup truck! Greater weight means that tires wear out sooner, raising maintenance costs. States receive no gasoline taxes from EVs, so states are now imposing EV license fees for road maintenance. EV road fees should be higher because of their weight.<\/p>\n\n\n\n

Hertz Rental purchased 60,000 EVs, but found that maintenance, repair, and insurance costs were higher than ICE rentals, so they sold<\/a> much of their EV fleet. An EV battery damaged in a collision must be replaced, a $5,000 to $20,000 charge. US insurance rates<\/a> for EVs may be 70% higher.<\/p>\n\n\n\n

Poor market demand, a halt to federal EV tax credits, the rollback of state ZEV regulations, and higher economic costs threaten to halt the ZEV revolution.<\/p>\n\n\n\n
