The U.S. government is in full retreat from its efforts to make vehicles more fuel-efficient, which it had been prioritizing, along with state governments, since the 1970s.

The latest move came on Feb. 12, 2026, when President Donald Trump and the Environmental Protection Agency issued a new rule rescinding the landmark “endangerment finding,” and reversing various emissions limits on cars and trucks. The 2009 finding stated that greenhouse gases pose a threat to public health and welfare. If the new rule stands up in court and is not overruled by Congress, it would undo a key part of the long-standing effort to limit greenhouse gas emissions from vehicles.

As a scholar of how vehicle emissions contribute to climate change, I know that the science behind the endangerment finding hasn’t changed. If anything, the evidence has grown that greenhouse gas emissions are warming the planet and threatening people’s health and safety. Heat waves, flooding, sea-level rise and wildfires have only worsened in the decade and a half since the EPA’s ruling.

Regulations over the years have cut emissions from power generation, leaving transportation as the largest source of greenhouse gas emissions in the U.S.

The scientific community agrees that vehicle emissions are harmful and should be regulated. The public also agrees, and has indicated strong preferences for cars that pollute less, including both more efficient gas-burning vehicles and electric-powered ones. Consumers have also been drawn to electric vehicles thanks to other benefits such as performance, operation cost and innovative technologies.

That is why I believe the EPA’s move will not stop the public and commercial transition to electric vehicles, but it will make that shift harder, slower and more expensive for everyone.

Putting carmakers in a bind

The most recent EPA rule about vehicle emissions was finalized in 2024. It set emissions limits that can realistically only be met by a large-scale shift to electric vehicles.

Over the past decade and a half, automakers have been building up their capability to produce electric vehicles to meet these fleet requirements, and a combination of regulations such as California’s zero-emission-vehicle requirements have worked together to ensure customers can get their hands on EVs. The zero-emission-vehicle rules require automakers to produce EVs for the California market, which in turn make it easier for the companies to meet their efficiency and emissions targets from the federal government. These collectively pressure automakers to provide a steady supply of electric vehicles to consumers.

The new EPA move would undo the 2024 EPA vehicle-emissions rule and other federal regulations that also limit emissions from vehicles, such as the heavy-duty vehicle emissions rule.

The possibility of a regulatory reversal puts automakers into a state of uncertainty. Legal challenges to the EPA’s shift are all but guaranteed, and the court process could take years.

For companies making decade-long investment decisions, regulatory stability matters more than short-term politics. Disrupting that stability undermines business planning, erodes investor confidence and sends conflicting signals to consumers and suppliers alike.

A slower roll

The Trump administration has taken other steps to make electric vehicles less attractive to carmakers and consumers.

The White House has already suspended key provisions of the Inflation Reduction Act that provided tax credits for purchasing EVs and halted a US$5 billion investment in a nationwide network of charging stations. And Congress has retracted the federal waiver that allowed California to set its own, stricter emissions limits. In combination, these policies make it hard to buy and drive electric vehicles: Fewer, or no, financial incentives for consumers make the purchases more expensive, and fewer charging stations make travel planning more challenging.

Overturning the EPA’s 2009 endangerment finding would remove the legal basis for regulating climate pollution from vehicles altogether.

But U.S. consumer interest in electric vehicles has been growing, and automakers have already made massive investments to produce electric vehicles and their associated components in the U.S. – such as Hyundai’s EV factory in Georgia and Volkswagen’s Battery Engineering Lab in Tennessee.

Global markets, especially in Europe and China, are also moving decisively toward electrifying large proportions of the vehicles on the road. This move is helped in no small part due to aggressive regulation by their respective governments. The results speak for themselves: Sales of EVs in both the European Union and China have been growing rapidly.

But the pace of change matters. A slower rollout of clean vehicles means more cumulative emissions, more climate damage and more harm to public health.

The EPA’s move seeks to slow the shift to electric vehicles, removing incentives and raising costs – even though the market has shown that cleaner vehicles are viable, the public has shown interest, and the science has never been clearer. But even such a major policy change can’t stop the momentum of those trends.

Gas prices have a $5 tipping point: New research shows when Americans start looking at EVs

(Tiffany Miller for Hyundai) There is a moment at the gas pump when the number staring back at you stops feeling routine.

You expect the total to land somewhere familiar. And then, one day, it doesn’t. Not dramatically higher. Just high enough to feel different. Enough to make you pause before tapping your card.

According to new research from Hyundai Motor America, that moment is not hypothetical. For more than a third of American drivers, it has already happened. And for many, once it does, something shifts that does not quite shift back.

For 42% of Americans, pulling up to a pump now brings frustration or outright dread. Most have made peace with the routine, even if 39% describe their gas spend as “frustrating but expected.”

The experience at the pump hasn’t changed. The emotional weight of it has.

Most drivers have a number in their head where the math shifts. For 23% of those surveyed, $5 per gallon is where they would seriously start considering alternatives to a gas-powered vehicle. Not everyone will be moved by price, and 29% say they would not consider alternatives based on gas costs at all. But for a meaningful share of Americans, the tipping point is specific. It is a number on a sign, and many have seen it before.

More than one-third of Americans surveyed say a recent fill-up has already prompted them to research electric vehicles, and 23% say it has happened more than once.

What comes next is rarely dramatic. Some compare models or brands. Some search online. Some find themselves on an automaker’s website, further along than they expected to be. Most do not act on this impulse right away. But for a growing number, the pump is where the question starts.

The shift is real but uneven. If gas prices rose significantly and stayed high, 46% of those surveyed say they would be likely to seriously research an EV. Yet most Americans are still somewhere between curious and committed.

The pitch for electric vehicles is simple. Never stop for gas again. Nearly half of Americans say they would absolutely take that deal.

The transition is not frictionless. Charging access and range anxiety remain the top concern for 28% of potential buyers, and simple comfort with the status quo runs just as deep.

The desire to leave the pump behind is real. So is everything standing in the way.

The move toward electric vehicles is often framed as a long-term decision made with spreadsheets and incentive calculators, but for many Americans, it begins somewhere smaller. A routine fuel stop. A number that lands differently. A moment of hesitation before the receipt prints.

Methodology

Hyundai Motor America commissioned Atomik Research to conduct an online survey of 1,000 adults throughout the United States. The margin of error is plus or minus 3 percentage points at a 95% confidence level. Fieldwork was conducted between April 3 and April 6, 2026.

(Feature Impact) Everyone loves driving on clean highways and spotless local roads. Few people, however, realize the benefits of clean roads go well beyond mere aesthetics. Cleaner roads also mean cleaner and healthier local rivers, lakes and beaches.

That’s because harmful pollutants in local waters often run off untreated from highways and roads during strong storms. Those rains sweep trash, dripped oil, harmful chemicals and even dangerous bacteria from pet waste into local waters via stormways and sewers. This untreated runoff can affect people’s health, make water unsafe for swimming and harm aquatic life. Every year, such man-made “stormwater pollution” even closes portions of recreational rivers and beaches.

It’s up to everyone to help prevent human-caused stormwater pollution. Don’t wait for rain in the forecast to get started. Instead, follow these simple year-round tips from the experts at the California Department of Transportation to help make the cooling waters in California and beyond as fun and healthy as possible this summer.

Trash-Free Trips and Responsible Car Care

Summer can mean more road time traveling to your next adventure. Loose items in truck beds and on roof carriers or trash tossed from car windows can quickly become the next wave of stormwater pollution flowing into local waters. To reduce:

• Secure Your Load: Always securely tarp and tie down anything in a truck bed or on a roof rack. Items falling off vehicles are both a safety hazard and can become roadside debris.
• Keep a Car Trash Catcher: Designate a bag or container in your car for food wrappers, coffee cups and other small trash until you can dispose of it properly.
• Wash Smart: Commercial car washes that recycle water are superior for preventing road dirt and chemicals accumulated on your car from entering storm drains compared to washing in a driveway. If washing at home, do it on your lawn or a permeable surface where the water naturally filters into the ground and not street gutters.

Outdoor Adventures That Leave Only Footprints

Whether you’re hiking a mountain trail, picnicking at the park or relaxing on the beach, remember the outdoor golden rule: pack out everything you pack in. Food wrappers, plastic bottles and even seemingly small items like bottle caps and cigarette butts are some of the most common litter found in parks, waterways and along coastlines. When left behind, they’re not just eyesores; they’re prime candidates for being washed into waterways.

• Pro Tip: Choose reusable water bottles that clip onto bags to reduce pollution from discarded plastic bottles.

At Home and In Your Neighborhood

Even close to home, your actions can make a difference.

• Garden Care: When tidying up your garden or front lawn, sweep leaves and grass clippings into your green bin instead of hosing them down the driveway. Hosing yard waste into road gutters can clog storm drains and cause flooding.
• Pesticide Prevention: To protect waterways from harmful chemical runoff, opt for organic or eco-friendly alternatives for pest and weed control whenever possible.
• Scoop the Poop: Pet waste contains harmful bacteria that can contaminate waterways. In fact, the EPA estimates that just two days’ worth of waste from 100 dogs can produce enough bacteria to close a beach. Always pick up after your pets, especially when walking in your neighborhood or parks, and dispose of it in a trash bin.

Pollution in waterways doesn’t just look bad; it creates real problems, from harming wildlife and ecosystems to causing potential health issues for humans and pets who encounter contaminated water. The cleaner roads and surrounding areas are, the healthier rivers, lakes and beaches become. For more tips and resources, visit CleanWaterCA.com to ensure a clean, healthy summer for everyone.
