U.S. state legislatures are where the action is for placing guardrails around artificial intelligence technologies, given the lack of meaningful federal regulation. The resounding defeat in Congress of a proposed moratorium on state-level AI regulation means states are free to continue filling the gap.

Several states have already enacted legislation around the use of AI. All 50 states have introduced various AI-related legislation in 2025.

Four aspects of AI in particular stand out from a regulatory perspective: government use of AI, AI in health care, facial recognition and generative AI.

Government use of AI

The oversight and responsible use of AI are especially critical in the public sector. Predictive AI – AI that performs statistical analysis to make forecasts – has transformed many governmental functions, from determining social services eligibility to making recommendations on criminal justice sentencing and parole.

But the widespread use of algorithmic decision-making could have major hidden costs. Potential algorithmic harms posed by AI systems used for government services include racial and gender biases.

Recognizing the potential for algorithmic harms, state legislatures have introduced bills focused on public sector use of AI, with emphasis on transparency, consumer protections and recognizing risks of AI deployment.

Several states have required AI developers to disclose risks posed by their systems. The Colorado Artificial Intelligence Act includes transparency and disclosure requirements for developers of AI systems involved in making consequential decisions, as well as for those who deploy them.

Montana’s new “Right to Compute” law sets requirements that AI developers adopt risk management frameworks – methods for addressing security and privacy in the development process – for AI systems involved in critical infrastructure. Some states have established bodies that provide oversight and regulatory authority, such as those specified in New York’s SB 8755 bill.

AI in health care

In the first half of 2025, 34 states introduced over 250 AI-related health bills. The bills generally fall into four categories: disclosure requirements, consumer protection, insurers’ use of AI and clinicians’ use of AI.

Bills about transparency define requirements for information that AI system developers and organizations that deploy the systems disclose.

Consumer protection bills aim to keep AI systems from unfairly discriminating against some people, and ensure that users of the systems have a way to contest decisions made using the technology.

Bills covering insurers provide oversight of the payers’ use of AI to make decisions about health care approvals and payments. And bills about clinical uses of AI regulate use of the technology in diagnosing and treating patients.

Facial recognition and surveillance

In the U.S., a long-standing legal doctrine that applies to privacy protection issues, including facial surveillance, is to protect individual autonomy against interference from the government. In this context, facial recognition technologies pose significant privacy challenges as well as risks from potential biases.

Facial recognition software, commonly used in predictive policing and national security, has exhibited biases against people of color and consequently is often considered a threat to civil liberties. A pathbreaking study by computer scientists Joy Buolamwini and Timnit Gebru found that facial recognition software poses significant challenges for Black people and other historically disadvantaged minorities. Facial recognition software was less likely to correctly identify darker faces.

Bias also creeps into the data used to train these algorithms, for example when the composition of teams that guide the development of such facial recognition software lack diversity.

By the end of 2024, 15 states in the U.S. had enacted laws to limit the potential harms from facial recognition. Some elements of state-level regulations are requirements on vendors to publish bias test reports and data management practices, as well as the need for human review in the use of these technologies.

Generative AI and foundation models

The widespread use of generative AI has also prompted concerns from lawmakers in many states. Utah’s Artificial Intelligence Policy Act requires individuals and organizations to clearly disclose when they’re using generative AI systems to interact with someone when that person asks if AI is being used, though the legislature subsequently narrowed the scope to interactions that could involve dispensing advice or collecting sensitive information.

Last year, California passed AB 2013, a generative AI law that requires developers to post information on their websites about the data used to train their AI systems, including foundation models. Foundation models are any AI model that is trained on extremely large datasets and that can be adapted to a wide range of tasks without additional training.

AI developers have typically not been forthcoming about the training data they use. Such legislation could help copyright owners of content used in training AI overcome the lack of transparency.

Trying to fill the gap

In the absence of a comprehensive federal legislative framework, states have tried to address the gap by moving forward with their own legislative efforts. While such a patchwork of laws may complicate AI developers’ compliance efforts, I believe that states can provide important and needed oversight on privacy, civil rights and consumer protections.

Meanwhile, the Trump administration announced its AI Action Plan on July 23, 2025. The plan says “The Federal government should not allow AI-related Federal funding to be directed toward states with burdensome AI regulations … ”

The move could hinder state efforts to regulate AI if states have to weigh regulations that might run afoul of the administration’s definition of burdensome against needed federal funding for AI.

The Southeastern Pennsylvania Transportation Authority piloted a new enforcement tool in Philadelphia in 2023: AI-powered cameras mounted on seven of its buses. The results were immediate and dramatic: In just 70 days, the cameras flagged over 36,000 cars blocking bus lanes.

The results of the pilot gave the transportation authority, also called SEPTA, valuable data into bus route obstruction and insights into the role of technology to combat these problems.

In May 2025, SEPTA and the Philadelphia Parking Authority officially launched the program citywide. More than 150 buses and 38 trolleys across the city are fitted with similar artificial intelligence systems that scan license plates for possible violations. The system uses AI-powered cameras that use computer vision technology to spot vehicles blocking bus lanes and scans license plates to identify the vehicles breaking the rules. If the system flags a possible infraction, a human reviewer confirms it before a fine is issued: US$76 in Center City, $51 elsewhere.

This rollout comes as SEPTA faces a $213 million budget shortfall, with imminent service cuts and fare hikes.

I’m a professor of information systems and the academic director of LeBow College of Business’s Center for Applied AI and Business Analytics at Drexel University. The center’s research focuses on how organizations use AI, and what that means for trust, fairness and accountability.

In a recent survey the center conducted with 454 business leaders from industries including technology, finance, health care, manufacturing and government, we found that the use of AI is often rolled out faster than the governance needed to make sure it works fairly and transparently.

That gap between efficiency and oversight is especially common in public-sector organizations, according to our survey.

That’s why I believe it’s important for SEPTA to manage its AI enforcement system carefully to earn public trust, while minimizing risks.

Fairness and transparency

When cars block a bus lane, they clog traffic. The resulting delays can mess up a person’s day, causing missed connections or making riders late for work. That can leave riders with the feeling they can’t rely on the transit system.

So, if AI enforcement helps keep those lanes clear, it’s a win. Buses move faster, and commutes are quicker.

But here’s the issue: Good intentions don’t work if the system feels unfair or untrustworthy. Our survey also found that more than 70% of the surveyed organizations don’t fully trust their own data. In the context of public enforcement, whether it’s transit agencies or parking authorities, that’s a warning sign.

Without trustworthy data, AI-powered ticketing can turn efficiency into costly mistakes, such as wrongly issued citations that must be refunded, lost staff time correcting errors, and even legal challenges. Public confidence matters here because people are most likely to follow the rules and accept penalties when they see the process as accurate and transparent.

Furthermore, this finding from our survey really caught my attention: Only 28% of organizations report having a well-established AI governance model in place. Governance models are the guardrails that keep AI systems trustworthy and aligned with human values.

That’s troubling enough when private companies are using AI. But when a public agency like SEPTA looks at a driver’s license plate and sends the driver a ticket, the stakes are higher. Public enforcement carries legal authority and demands a higher level of fairness and transparency.

The AI label effect

One may ask, “Isn’t this ticketing system just like red-light or speed cameras?”

Technically, yes. The system detects rule-breaking, and a human reviews the evidence before a citation is issued.

But simply labeling the technology as AI can transform how it’s perceived. This is known as the framing effect.

Just calling something AI-driven can make people trust it less. Research has shown, whether a system is grading papers or hiring workers, that the exact same process draws more skepticism when AI is mentioned than when it isn’t. People hear “AI” and assume the machine is making judgment calls, so they start looking for flaws. Even if they think that AI is accurate, the trust gap never closes.

That perception means public agencies need to align AI-based enforcement with transparency, visible safeguards and easy ways to challenge mistakes. These measures increase trust in AI-based enforcement.

We’ve seen what can go wrong, and how quickly trust can erode, when an AI-based enforcement system malfunctions. In late 2024, AI cameras on Metropolitan Transportation Authority buses in New York City wrongly issued thousands of parking tickets, including nearly 900 cases where the drivers had actually followed the rules and parked legally.

Even if such errors are rare, they can damage public confidence in the system.

Build trust into the system

The Organization for Economic Cooperation and Development, the international body setting AI policy standards across dozens of countries, has found that people are most likely to accept AI-driven decisions when they understand how those decisions are made and have a clear, accessible way to challenge mistakes.

In short, AI enforcement tools should work for people, not just on them. For SEPTA, that could mean the following:

–Publishing clear bus-lane rules and any exceptions, so people know what’s allowed.

–Explaining safeguards, like the fact that every bus-camera violation is reviewed by Philadelphia Parking Authority staff before a ticket is issued.

–Offering a straightforward appeals process with management review and a right to appeal.

–Sharing enforcement data, such as how many violations and appeals are processed.

These steps signal that the system is fair and accountable, helping shift it from feeling like a ticketing machine into a public service that people can trust.

Today, approximately 1,800,000 acres of land in the United States is used for landfill waste disposal. In terms of volume, the U.S alone generated over 290 million tons of solid waste in 2018, an amount equivalent to about 235,000 Olympic-size swimming pools, assuming an average solid waste density of a half ton per cubic meter.

Roughly 9% – about 26 million tons – of this waste is made up of iron and steel. These are resources with a stable market value used in various civil infrastructure projects. As a team of environmental engineers, we wanted to know whether we could use iron-rich waste to produce iron oxide nanoparticles – a useful tool for combating water pollution and building engineering hardware.

All about nanoparticles

Iron oxide nanoparticles consist of iron and oxygen atoms and, because of their size, they exhibit unique physical and chemical properties. They are extremely small, typically at the nanoscale – one-billionth of a meter – in diameter.

The iron oxide nanoparticles we synthesized were a distinctive group called magnetite and maghemite. Initial studies have shown that nanoparticles in this group could help drugs get to the right part of the body, make batteries in electric vehicles more efficient and improve sensors for detecting toxic gas, as well as sound and motion.

Because these nanoparticles are made of iron, they’re both magnetic and stable. Their tiny size gives them a large surface area relative to their volume, allowing them to grab pollutants in water. Additionally, their magnetic nature makes them ideal for building extremely small and thin electrical components.

In our work, we wanted to find a new way to produce them using waste materials. In our newest study, published in the RSC Sustainability journal, we developed an eco-friendly method to synthesize iron oxide nanoparticles from expired over-the-counter iron supplements. This approach not only gives value to discarded products but also supports a more sustainable and circular method of production.

The research process

To conduct our study, we used a method called hydrothermal carbonization to produce these magnetic nanoparticles. We were able to source a large amount of expired iron supplements from a local health care center.

The hydrothermal carbonization process uses a turbocharged version of the kind of pressure cooker you might have in your kitchen. For our recipe, we combined 20 grams each of expired iron supplements and water in a specialized pressure reactor. We then cooked the mixture at 527 degrees Fahrenheit (275 degrees Celsius) for six to 12 hours. Under this intense temperature and pressure, the supplements broke down, which produced tiny – 10- to 11-nanometer – particles.

The end product included a solid charcoal-like material called hydrochar, which made up about 20% to 22% of the product. The hydrochar consisted of the iron oxide nanoparticles and graphite, a carbon-rich material that gave the hydrochar its charcoal-like look. The rest became gas and a dark, tarlike liquid separate from the hydrochar.

Hydrothermal carbonization is not the only method used to make iron oxide nanoparticles. There are other conventional methods such as coprecipitation, which involves mixing chemicals to form solids. Another method is pyrolysis, where materials are heated in the absence of oxygen. And finally, gasification, which heats materials in the presence of oxygen.

These methods usually require a higher energy input, around 1,292 to 1,832 degrees Fahrenheit (700 to 1,000 C), or harsh salt chemicals. In contrast, hydrothermal carbonization, the method we used, is water-based and can happen at a low temperature.

We compared our hydrothermal carbonization process’s energy use with other methods and found it had the lowest environmental impact.

From polluted water to clean

The iron oxide nanoparticles we created are very useful for water treatment. They are particularly good at removing oil and heavy metals such as lead, cadmium, zinc and chromium from water. These are pollutants known to cause serious health issues, including cancer.

You can either mix them with polluted water or allow the water to pass through them, similar to a common household filter.

To test their performance, we mixed our iron oxide nanoparticles in wastewater samples containing methylene blue dye, a common pollutant in textile and manufacturing wastewater. We found they removed over 95% of the dye, and because the particles are magnetic, we could remove them from the treated water using a magnet so they didn’t contaminate the water.

Depending on the type of pollutants in the water, iron oxide nanoparticles can sometimes be reused after they’re heated again.

Moving forward

We produced a small amount of these nanoparticles in the lab for this study. However, large quantities of iron waste are sent to landfills. These include materials such as steel sludge and metal scraps. So in theory, many more of these nanoparticles could be produced in the future. If produced in large enough quantities, large water and wastewater plant filtration systems could use these particles to treat much larger amounts of water.

But landfill waste isn’t all one type of waste. Iron-rich waste may be contaminated with other materials, making its sourcing, sorting and recycling both resource-intensive and costly. To scale up this technology sustainably, researchers will need to first overcome these challenges.

On the bright side, economists predict that alternative metals, including iron oxide nanoparticles, may help meet production demands for future technologies and artificial intelligence. These nanoparticles can be used to manufacture high-performance computing components. These components include magnetic memory storage and semiconductors found in our everyday technologies.

Lots of the critical metals currently used are expensive, scarce or geopolitically sensitive: cobalt, nickel and lithium. As a result, our team is starting to explore how this hydrothermal carbonization-based method can be scaled and applied to other types of waste materials.

Our long-term goal is to expand the tool kit for sustainable nanoparticle production while continuing to address both environmental challenges and materials demands for future innovations.

When the head of the Federal Emergency Management Agency’s urban search and rescue team resigned after the deadly July 4, 2025, Texas floods, he told colleagues he was frustrated with bureaucratic hurdles that had delayed the team’s response to the disaster, acccording to media reports. The move highlighted an ongoing challenge at FEMA.

Ever since the agency lost its independent status and became part of the Department of Homeland Security in the early 2000s, it has faced complaints about delays caused by layers of bureaucracy and red tape, leaders at the top with little experience in emergency response, and whiplash policy changes.

Now, the Trump administration is cutting jobs at FEMA and talking about dismantling the agency, which would push more responsibility for disaster response to the states.

Yet, federal emergency management is crucial in America.

I run the Hazards Vulnerability & Resilience Institute at the University of South Carolina and for years have worked with states and communities facing hazards and disasters. To better understand FEMA’s value, let’s take a look back at how the nation responded to disasters before the agency existed, and what history reveals about when FEMA was most effective.

Disaster response without the US government

Before 1950, disaster relief and response were not considered a federal responsibility. When a hurricane, flood or tornado hit, community members and humanitarian groups, such as the American Red Cross or Salvation Army, brought in food, shelter and medical aid and solicited charitable donations to help people rebuild.

State and local governments had primary responsibility for disaster response. But mostly people relied on family, neighbors and charity.

Federal aid was approved on a case-by-case basis. War Department guidelines in 1917 stated that aid would be allowed only if a senior military officer certified that responding to the disaster would exceed local and state resources.

Then the Great Mississippi Flood of 1927 and the 1930s Dust Bowl gave new meaning to the concept of disaster in America.

In 1927, the Mississippi River broke through its levees, submerging more than 1 million acres of land across seven states. An estimated 700,000 people were displaced from their homes and workplaces.

Herbert Hoover, then U.S. commerce secretary, was given full authority to create, coordinate and carry out the federal relief effort. The Red Cross set up camps using tents provided by the War Department. Coast Guard and Navy boats rescued people stranded by flooding. But the response drew criticism for the lack of direct federal money to help flood survivors and the treatment of Black sharecroppers and laborers.

A few years later, the droughts of the Dust Bowl era began destroying crops in the Great Plains, causing widespread damage.

Federal disaster aid begins to take shape

After the flood, the federal government began to formalize its role in disaster management.

Flood control projects became a federal responsibility with the passage of the Flood Control Act of 1928. President Franklin D. Roosevelt’s New Deal provided emergency relief to farmers in the Great Plains and set up the Soil Conservation Service to help them reduce the effects of future droughts. These were among the first disaster mitigation policies at the federal level.

There was little coordination among agencies, however. Various aspects of disaster relief and recovery were handled by the departments of Defense, Agriculture, and Housing and Urban Development and the Small Business Administration. Each had its own rules and requirements.

In 1950, Congress passed the Federal Disaster Relief Act, establishing the first permanent authority for federal disaster relief.

The act gave the president the responsibility to determine how aid would be distributed and which agencies would be involved. The legislation also broadened the federal mission to include disaster preparedness and mitigation and formalized the process for issuing presidential disaster declarations.

The creation of FEMA

By the 1970s, large-scale disasters such as hurricanes Betsy (1965) and Camille (1969), and the fragmented disaster response, led the National Governors Association to call for a single comprehensive emergency management agency. Its report provided the blueprint for President Jimmy Carter’s 1979 executive order that established the Federal Emergency Management Agency, or FEMA.

The new agency became the home for emergency management within the executive branch. It was intentionally designed as an independent federal administrative agency that could work across federal agencies to support state and local governments in times of crisis.

FEMA wasn’t created to lead the disaster response. Instead it helps state and local officials by mobilizing federal resources, such as search and rescue, debris removal and funding when a disaster overwhelms the state’s capacity. FEMA could do this quickly because of established federal contracts and its ability to move equipment and responders into the region before a disaster hits.

When things began to fall apart

However, FEMA’s ability to act fast changed after the Sept. 11, 2001, terrorist attacks. The agency was restructured as a unit in the newly formed Department of Homeland Security. But the Department of Homeland Security’s focus was on terrorism and law enforcement, not natural disasters.

The loss of autonomy and direct reporting to Congress, unfunded mandates outside the scope of the 1988 Stafford Disaster Relief and Emergency Assistance Act, and major increases in the number of large and complex disasters stretched FEMA’s capabilities.

When Hurricane Katrina hit New Orleans in 2005, FEMA’s response drew widespread criticism. It was slow to deploy people and supplies and lacked enough experienced responders who knew what to do. Decision-makers were not familiar with new national response plans. Further breakdowns in communications and a lack of coordination among agencies led Congress to declare the Hurricane Katrina response a failure of initiative and agility.

FEMA’s reputation improved after the government brought in more experienced leadership and committed to preparedness planning and better response capabilities.

However, the first Trump administration, from 2017 to 2021, reversed those gains. Three different heads of FEMA in four years led to understaffing and conflicting directions.

As Trump took office for the second time in 2025, he and his administration talked about dismantling FEMA and pushing more disaster management to states. Job cuts and resignations at FEMA reduced the number of employees with training and experience vital in disasters. Political appointees to senior roles in the agency and in the Department of Homeland Security lacked emergency management training and experience.

A new policy that all purchases over US$100,000 be personally approved by Homeland Secretary Kristi Noem led to more resignations. For disaster response, a delay in waiting for a signature to work its way up the chain can cost lives.

What now?

Dismantling FEMA and leaving little or no federal coordination of disaster response puts states in a difficult position.

States must balance their budgets every year, and increasingly “rainy day” funds are insufficient to cover unexpected large disasters. As the federal government shifts other financial responsibilities to states, funds will diminish further.

A single disaster can cause hundreds of millions of dollars in damage and require widespread disaster response and then relief efforts. Since 1980, the cumulative cost of weather-related disasters has exceeded $2.9 trillion. With a warming atmosphere producing more intense storms, increasing human and economic harm are likely.

Members of Congress have proposed making FEMA an independent, Cabinet-level agency again. I see some distinct advantages in doing so:

• Fewer management layers would enable faster deployment of federal supplies and personnel to assist disaster response.

• A streamlined, more nimble agency could cut red tape for disaster survivors needing assistance, meaning delivering relief funding faster and more equitably.

• If an independent FEMA had responsibility for recovery beyond its current 180-day reimbursement limits, that could improve long-term recovery efforts, especially if Congress provided permanent funding streams and consistent rules and regulations.

The Trump administration’s efforts to dismantle FEMA are shortsighted in my view. Instead, I believe the best move is to restore FEMA as an independent executive agency as it was originally envisioned.

It’s been about six months since the U.S. Department of Education sent a “Dear Colleague” letter to all schools that receive federal funding, warning them that they could risk losing this money if they promote what the department calls “pervasive and repugnant” racial preferences.

The letter, among other things, reversed previous presidents’ positions on how diversity, equity and inclusion influences schools’ disciplinary measures. It advised schools to, within two weeks, begin to eliminate all discipline protocols rooted in DEI, on the grounds that this work is discriminatory against white students.

Trump also issued an executive order, “Reinstating Commonsense School Discipline Policy,” in April 2025, doubling down on the letter.

Trump’s letter and executive order exert an unusual level of influence over how schools can decide the best way to teach and, when necessary, discipline students. It also cuts against recognized research that Black, Latino and Native American students are disciplined more frequently and harshly than white and Asian students.

I am an educational scholar who has spent the past 13 years analyzing school discipline policy. While previous administrations have issued “Dear Colleague” letters to schools, Trump’s is the first that frames itself as though it were law – setting a potential new precedent for the executive branch to issue educational mandates without the approval of the judicial or congressional branches of government.

While all but two states have responded to Trump’s letter, about half of them have said they are not going to comply with its terms – despite the administration’s threat of cutting funding if they do not follow the guidance.

Understanding DEI in education

Equity-oriented education, or diversity, equity and inclusion, refers to an ideology and programming that intend to ameliorate patterns of racial inequality. In the context of discipline in schools, DEI strategies could include teachers having conversations with children about their behavior, rather than immediately suspending them.

Research shows that these techniques can help reduce racial discipline gaps in academic achievement and disciplinary outcomes.

The Obama administration in 2014 recognized this research in its own “Dear Colleague” letter to schools. The administration advised schools to either reform their discipline practices toward nonpunitive alternatives to suspension or risk being investigated for discrimination.

The first Trump administration rescinded this letter in 2018.

Then, in 2023, the Biden administration released a document along the same lines as Obama’s letter.

Trump’s February 2025 letter grouped all of these recommendations under the banner of “DEI” and argued that such practices are discriminatory, privileging students of color over white and Asian students.

In his April executive order, Trump reiterated that if schools did not eliminate DEI, they would be out of compliance with Title VI of the 1964 Civil Rights Act. This act prohibits discrimination on the basis of race, color or national origin,

Public school districts regularly have to issue a certificate of compliance to the government showing that their work is in line with Title VI.

While the Trump administration characterizes DEI as “smuggling racial stereotypes and explicit race-consciousness into everyday training, programming, and discipline,” it does not define exactly what constitutes DEI programming.

This puts school districts at risk of losing funding if they maintain any initiatives related to racial equality.

Legal concerns with Trump’s directives

The executive office and members of Congress typically issue “Dear Colleague” letters, which are not legally binding, to advise schools and others on policy.

Yet Trump’s letter was written like a mandate and reinforced by an executive order, which is legally binding.

Some scholars are calling the letter an “overreach” of legal authority.

In the spring of 2025, I analyzed states’ responses to Trump’s letter and executive order.

Two states, Iowa and Tennessee, had not yet provided public responses.

Twenty-three states complied with the administration’s directive by signing the letter as of May 30. Some, like Oklahoma, not only certified the letter but also passed state laws banning DEI policies and programs.

The remaining 25 states refused to certify the letter, asserting that they already complied with Title VI and that their policies are not discriminatory.

In addition, 19 of those 25 states sued the Trump administration over the letter in April, culminating in a court injunction later that month that temporarily released states from having to comply with its demands.

I noticed that many states that refuted Trump’s letter used the same exact words in their responses, signaling a concerted effort to resist Trump’s directives. States that did not sign on to the letter but objected to its intent generally resisted on legal grounds, ethics or both.

A legal argument

Most states that rejected it grounded their refusal to sign Trump’s letter in federal law. They cited the Civil Rights Act and the Paperwork Reduction Act, which protects states from having to file redundant paperwork. Because these states already certified compliance with Title VI, this argument goes, they should not have to do so again under Trump’s directive.

Education commissioners from a few states, including Illinois and Minnesota, also cited specific language used by Betsy DeVos, Trump’s former education secretary in his first term, who supported DEI policies.

Charlene Russell-Tucker, the education commissioner for Connecticut, also pointed out that in order for the federal government to cancel DEI programming, it would have to first legally change the definition of Title VI.

States resisting on other grounds

Some education officials also argued that their DEI work is ideologically necessary for providing supportive learning environments for all students.

Patrick Tutwiler, Massachusetts’ interim education commissioner, wrote in an April 16 letter, for example, that “Massachusetts will continue to promote diversity in our schools because we know it improves outcomes for all of our kids.”

Other officials displayed more subtle resistance. Randy Watson, Kansas’ education commissioner, for example, affirmed the state’s “commitment to comply with all Federal statutes,” including Title VI – but did not explicitly address Trump’s “Dear Colleague” letter.

Similarly, Kentucky informed the Department of Education of its compliance with federal law, while simultaneously encouraging local districts to continue diversity, equity and inclusion work.

Mississippi’s state department of education pointed out that school districts operate independently, so the state cannot force policies on them. However, Mississippi signaled compliance by citing a new state law banning DEI and confirmed that each of its individual school districts have already certified compliance with federal laws.

More legal pushback

It is not yet clear what might follow the April court injunction, which largely prevented the Department of Education from cutting federal funding to schools that continued their DEI-related programs and policies.

While the Trump administration has made major cuts to the Department of Education, it has not announced that states refusing to certify the letter will lose funding.

This is the first time an administration is issuing such a direct threat to withhold K-12 funding, placing schools in an unknown place, without a clear blueprint of how to move forward.

Have you ever noticed a sign in a doctor’s office saying that you may have to pay extra insurance costs if you discuss additional problems with your physician?

If so, you’re not alone. As health care spending continues to rise, providers are being asked to warn patients about any potential unexpected costs – for example, insurance charges for additional services at an otherwise fully covered annual wellness visit.

But our research shows these warning signs could have an unintended consequence, discouraging patients from speaking openly with their doctors.

We are professors who research how people make spending decisions and were inspired to study this issue by real signs at a university-affiliated health care office. Other researchers have found many reasons why people hesitate to speak openly with their doctors, and we wondered whether these signs might be another factor. So we conducted some experiments.

In two studies, we found that when people saw an insurance warning sign, they were less willing to raise a wide variety of issues during a physical exam. These included both short-term issues such as headaches, fatigue and arthritis pain in the finger joints, and previously diagnosed, chronic conditions including high blood pressure, Type 2 diabetes and asthma.

In a third study, we tested whether it was what the sign said – or just the mere presence of a sign mentioning costs – that made people reluctant to speak up. We showed participants either no sign, an insurance warning sign, or a sign about a prescription drug discount program, which was also modeled after a real sign in the same doctor’s office. Only people who saw the insurance sign were less likely to speak up.

Why it matters

Frank conversations between patients and providers are essential for good health care. They allow providers to tailor medications, reduce side effects and find treatments that are right for each patient. What’s more, treating issues earlier rather than later generally leads to better outcomes and costs less in the long run.

We found that insurance warning signage, no matter how necessary or well intended, can discourage patients from sharing important health information. This could cause delays in important care, leading to unnecessary discomfort and stress as patients suffer with untreated issues.

Health care offices need to include certain insurance disclosures to inform patients of their rights under the No Surprises Act, which took effect in 2022. However, providers and administrators should be aware that their patients may often have cost concerns.

Doctors’ offices can try to find ways to communicate potential insurance costs while also encouraging patients to have open and honest discussions with their providers. The signage at the office that inspired this work had many words bolded and underlined, which may have made it feel especially aggressive to some patients.

It’s important for patients to know that they should never ignore symptoms. In fact, raising a concern as early as possible with a doctor or another health care provider can save more money down the road.

What still isn’t known

We weren’t able to study the long-term impacts of such signs, and it’s possible they have even more negative effects than we uncovered – for example, by making patients reluctant to have annual wellness visits.

It’s also unclear how often health care professionals actually report such conversations to insurers, especially when the issues are brought up briefly during a checkup and don’t require additional testing or treatment at that time.

But the research is clear on one point: When patients feel they can speak freely to their doctors, they get better care. That’s why doctors and other health care professionals should be aware that even well-intended warning signs may encourage patients to keep silent.

On July 28, 2025, a 27-year-old gunman entered a New York City office building that is home to the National Football League’s headquarters. He shot and killed four people and injured one other before killing himself.

In a note found in his wallet, he claimed he had chronic traumatic encephalopathy, or CTE, a degenerative brain condition believed to develop from repeated traumatic brain injuries. He asked experts to study his brain.

CTE has received much attention over the past two decades as multiple NFL players have been diagnosed with the condition after their deaths. The 2015 movie “Concussion,” about a forensic pathologist named Dr. Bennet Omalu who documented the first case of CTE in an NFL player, also highlighted the issue.

The gunman in the New York City shooting played high school football, but he did not play professionally. It is not known whether he had CTE.

I’m a clinical psychologist who studies mental health issues and their relationship to physical illness. Although people generally associate CTE with professional athletes, a growing body of research, including my own work, shows that adolescents and young adult athletes experience traumatic brain injuries that can have both short-term and long-term effects on mental health. In my view, young players and their families, as well as coaches, should pay attention to these emerging risks.

From traumatic brain injuries to CTE

At least 55 million people worldwide are thought to experience a traumatic brain injury each year. The actual number may be higher, as many brain injuries are never diagnosed or treated.

Some people with a brain injury recover quickly. Others do not. Over half of people with a brain injury reported mental health symptoms one year later. These include difficulties concentrating, memory problems and irritability, as well as physical concerns such as recurrent headaches and difficulties with balance. Many people who sustain a traumatic brain injury also report difficulties with anxiety, depression and substance misuse as they are recovering. Some report thoughts about ending their lives or suicide attempts.

Although the link between traumatic brain injuries and CTE is still being studied, many experts believe that the condition is caused not by a single, severe blow to the head but by repeated trauma to the head over time.

It is not uncommon for former competitive athletes across a range of contact sports to believe they may have CTE – not only because they remember the injuries or being diagnosed with a concussion, but also because they experience many of the cognitive symptoms that affect people with traumatic brain injuries and sometimes misuse alcohol, pain medications or other substances to cope with them.

However, there’s no way for someone to get a diagnosis for the condition while they are experiencing these symptoms. There is currently no test for CTE. Doctors generally diagnose it after an autopsy.

Repeated brain injuries in youth sports

The focus on CTE has brought greater interest in the effects of traumatic brain injuries in general. Such injuries are common not only in professional athletes but also in adolescents and young adults who play sports. They are seen frequently in military veterans as well.

In a study published in March 2025, my colleagues and I assessed more than 500 varsity and club sport athletes. We found that 75% said they had experienced a head injury before starting college. Almost 40% reported being diagnosed with at least one concussion, and just over half of those athletes experienced a loss of consciousness.

We also found that student athletes who had experienced head injuries were much more likely to be diagnosed with at least one psychiatric disorder in their lifetime. They were more likely to drink alcohol excessively and have a substance use disorder in their history. Greater symptoms of an alcohol use disorder were associated with having their first head injury at an earlier age, as well as having more head injuries, diagnosed concussions and losing consciousness from those injuries.

These troubling observations highlight the often overlooked mental health effects of head injuries in adolescents and young adults. Our study aligns with others that have found a relationship between sports-related traumatic brain injuries and mental health symptoms – and it is among the first to look not only at self-reported symptoms but also at formal psychiatric diagnoses.

How exactly these cases might relate to CTE is unknown, but there are hints of a link: Researchers examining the records of 152 former contact sport athletes who died before age 30 identified signs of CTE in the brains of 40% of them. Family members described mental health symptoms in the majority of them, and alcohol and substance misuse were reported in approximately one-third.

Increasing safeguards for brain health in young athletes

While head injuries in youth sports were once met with a shrug, youth sports leagues are increasingly paying attention to the issue.

Studies suggest that limiting the amount of physical contact in preseason training or between games can reduce young players’ head injury risks. Coaches of contact sports such as football and soccer often receive training on identifying the signs and symptoms of head injuries and are given strategies to manage them.

Athletic trainers, routinely available at many high school sporting events, are involved in sporting events for younger children as well. As first responders to athletic injuries, they are trained to assess symptoms of head injuries and can provide guidance, as part of a medical team, on when an athlete can return to play. Athletic trainers also may be well positioned to observe some of the mental health symptoms commonly seen after head injuries.

Following a head injury, parents and guardians should also keep an eye on their athlete. Changes in mood or behavior after a head injury warrant a referral to a neurologist or mental health professional for additional assessment and treatment.

The study was supported by a multi-project grant from the FY2015 Pennsylvania Commonwealth Universal Research Enhancement Program Formula Funding (PA CURE). .

Violence continues several weeks after clashes started between armed Bedouin clans, Sunni jihadist groups and Druze fighters on July 14, 2025, in Sweida, a city in southern Syria.

Hundreds of Druze were killed in the clashes, and Syria’s defense minister deployed forces to contain the sectarian fighting.

The Druze are a religious minority in the Levant, the region covering roughly modern-day Syria, Lebanon, Jordan, Israel and Palestinian territories. The faith originated in Egypt as an offshoot of the Fatimid tradition, a branch of Shiite Islam. Today, there are about 1 million to 1.5 million Druze worldwide, more than half of whom live in Syria. Most others live in Lebanon, Israel, Jordan and the Israeli-occupied Golan Heights.

We are experts in Druze and Lebanese history, and we know that the conflict in Sweida is regarded by the Druze of Lebanon – and the Druze everywhere – as a deeply personal matter.

What’s more, the horror stories coming out of Sweida are reverberating in Lebanon, where many Druze also fear the risk of sectarian violence, and distrust in current leadership.

Bonds forged through a long history

Many scholars attribute the strong bond between the Druze of Syria and Lebanon to their shared faith – which is partly true – but they often overlook an equally vital element: a collective conscience shaped by a distinctive origin story.

The Druze see themselves as an ancient, blood-related tribal coalition that evolved into an extended family spread across regions. This self-perception is so deeply rooted that it gave rise to a well-known Levantine saying: “The Druze are like a copper plate – wherever you strike it, it rings.”

According to local tradition, several Druze families from Mount Lebanon migrated to the Hawran region, south of Damascus, more than three centuries ago, paving the way for thousands of others to follow. Sweida is the capital city of the Druze region in Ḥawran. The region of Ḥawran is the second-youngest Druze settlement – after Jordan – dating back to the 18th century.

A foundational event in the community’s modern history was the Druze uprising in Ḥawran against the Ottoman governor of Egypt, Muhammad Ali Pasha, in 1837.

The governor had insisted on imposing conscription and disarmament on the Druze. The community rebelled since both measures would put their security and autonomy at risk, and the governor sent the army to occupy the Levant.

During the revolt, Druze from Mount Lebanon and Wadi al-Taym – a historical Druze region encompassing the modern-day Lebanese districts of Rashayya and Hasbayya in the southeast, near the Syrian border – rose up to divert the Egyptian army and sent fighters to support their Syrian kin.

In 1838, many of these Lebanese fighters were killed, particularly in what is known as the Battle of Wadi Bakka, near the Lebanese-Syrian border; an entire Druze battalion was besieged by the Egyptian forces and nearly wiped out.

In 1860, a third civil war involving the Druze under the Ottomans broke out in Mount Lebanon between the Druze and the Maronites. The Maronites are a group of Eastern Catholic Christians predominantly in Lebanon. The conflict centered on control of the southern regions of the mountain – historically known as the Druze Country.

As violence escalated between the two communities, the Druze of Ḥawran came to the aid of their fellow Druze in Mount Lebanon, tipping the balance in their favor.

During World War I, Mount Lebanon was hit by a famine and around 200,000 people died. The Druze of Ḥawran supported the Druze in Lebanon by supplying them with essential grain, and many Lebanese Druze resettled in Ḥawran to escape starvation.

These are just a few examples from a long history of mutual support that, in the Druze collective memory, reinforces the belief that they are not merely a community – but a tightly knit extended family that spans national borders.

Shifting borders

As a religious minority in the Levant, the Druze have long defended their religious freedom and identity.

The principalities in Mount Lebanon were most successful at realizing and keeping religious autonomy from at least the 12th century to the 19th century; they ensured the Druze were ruled by one of their own emirs and could practice their religious and social customs freely. The modern state of Lebanon evolved out of these autonomous principalities.

However, the Druze never viewed their struggle for social and religious autonomy as a license to attack their neighbors – especially fellow Arab Muslims – but rather as a safeguard for their faith and security.
The Druze do not equate religious freedom and autonomy with independence. In fact, many Druze in the region oppose the idea of a Druze state.

Starting in the 1930s, Zionist leaders hoping to create a Jewish state sought to exploit this Druze desire toward autonomy by proposing the creation of a Druze state in Ḥawran. They envisioned it as a friendly buffer state bordering the future state of Israel. More importantly, they wanted to push Druze out of Galilee and Mount Carmel knowing that they lived there for many centuries.

After the Six-Day War in 1967 between Israel and Egypt, Jordan and Syria, this idea expanded into a broader Israeli plan to fragment Syria and Lebanon into five sectarian states: an Alawite state in the north, a Christian state in the west, a Druze state in the south, a Kurdish state in the east and a Sunni state at the center.

Since Oct. 7, 2023, some Druze leaders – such as Walid Jumblatt, former minister, and head of the Progressive Socialist Party – have raised concerns that Israel could be attempting to revive this plan to reshape the region into a “New Middle East” with potentially new borders in Syria, Iraq, Lebanon, and the Palestinian territories. In fact, since the fall of the Assad regime in Syria, Jumblatt has been vocal about the rise of potential new borders.

Historically, the highest Druze religious authorities rarely engage in day-to-day politics. Yet, they are still expected to offer moral and political guidance during times of crisis, as the community sees them as guardians of faith, identity and ethics.

Recently, the leading Druze spiritual authority in Lebanon, Sheikh Amin al-Sayegh – who has been at odds with Jumblatt on internal communal affairs – voiced similar concerns in a public letter of condolence and support to the Syrian Druze. He emphasized the community’s Arab Islamic identity and warned against prioritizing material security over the historical Druze identity. Al-Sayegh’s stance reflects long-standing Druze political principles rooted in centuries of tradition.

The political message was clearly hinting at a rising tendency among some Druze, including Syrians, to consider stronger ties with Israel for security purposes.

Growing fear of sectarian violence

Lebanon has a long history of sectarian violence, and the recent events in Syria are indeed alarming to Lebanon’s religious minorities, including the Druze.

In March 2025, over 1,400 Alawite civilians were massacred, mostly in coastal cities like Latakia and Baniyas, by the newly formed Syrian forces.

In June, 25 Syrian civilians were killed and over 60 injured when a Sunni extremist group attacked the Greek Orthodox Church of the Prophet Elias in Damascus. And as of mid-July, Bedouin clans and the state security forces of the Sharaa regime have been targeting and killing Druze civilians in Sweida.

With numerous Bedouin tribes present in Lebanon, and tension evolving into an open sectarian confrontation, Druze leaders there fear that the sectarian violence could spill over into their own communities due to the Syrian Bedouins’ call for general mobilization of Arab tribes in the region against the Druze. This call is based on unverified reports of Druze killing Bedouin civilians.

Druze leadership in Lebanon

Despite growing frustration over Lebanon’s deepening economic crisis – partly attributed to political leadership – most Lebanese Druze remained loyal to traditional figures like Jumblatt, who was long viewed as the most capable guardian of their security and communal interests.

But the shock of recent violence in Sweida, where militias aligned with the Syrian regime targeted Druze civilians, has unsettled that loyalty. Many Lebanese Druze had expected their leaders to use their external influence to shield their kin across the border. The perceived failure to do so – combined with Jumblatt’s continued support for the regime led by President Ahmed al-Sharaa in Syria – has sparked widespread criticism within the community. Jumblatt himself acknowledged this strong criticism in a recent interview.

For many Druze, the brutal events in Sweida were fiercely traumatic and have forced them to painfully confront their long-standing core political priorities: security and the preservation of religious and social autonomy. And in light of this, some are beginning to reassess long-held assumptions that current leadership can preserve their religious autonomy and, more importantly, keep them safe.

Hours after savoring that perfectly grilled steak on a beautiful summer evening, your body turns traitor, declaring war on the very meal you just enjoyed. You begin to feel excruciating itchiness, pain or even swelling that can escalate to the point of requiring emergency care.

The culprit isn’t food poisoning – it’s the fallout from a tick bite you may have gotten months earlier and didn’t even notice.

This delayed allergic reaction is called alpha-gal syndrome. While it’s commonly called the “red meat allergy,” that nickname is misleading, because alpha-gal syndrome can cause strong reactions to many products, beyond just red meat.

The syndrome is also rapidly spreading in the U.S. and around the globe. The Centers for Disease Control and Prevention estimates as many as 450,000 people in the U.S. may have it. And it’s carried by many more tick species than most people realize.

What is alpha-gal syndrome?

Alpha-gal syndrome is actually an allergy to a sugar molecule with a tongue-twisting name: galactose-alpha-1,3-galactose, shortened to alpha-gal.

The alpha-gal sugar molecule exists in the tissues of most mammals, including cows, pigs, deer and rabbits. But it’s absent in humans. When a big dose of alpha-gal gets into your bloodstream through a tick bite, it can send your immune system into overdrive to generate antibodies against alpha-gal. In later exposure to foods containing alpha-gal, your immune system might then launch an inappropriate allergic response.

Often this allergy is triggered by eating red meat. But the allergy also can be set off by exposure to a range of other animal-based products, including dairy products, gelatin (think Jell-O or gummy bears), medications and even some personal care items. The drug heparin, used to prevent blood clotting during surgery, is extracted from pig intestines, and its use has triggered a dangerous reaction in some people with alpha-gal syndrome.

Once you have alpha-gal syndrome, it’s possible to get over the allergy if you can modify your diet enough to avoid triggering another reaction for a few years and also avoid more tick bites. But that takes time and careful attention to the less obvious triggers that you might be exposed to.

Why more people are being diagnosed

As an entomologist who studies bugs and the diseases they transmit, what I find alarming is how rapidly this allergy is spreading around the globe.

Several years ago, experts thought alpha-gal syndrome was primarily limited to the southeastern U.S. because it was largely associated with the geographical range of the lone star tick.

However, both local and global reports have now identified many different tick species across six continents that are capable of causing alpha-gal syndrome, including the prolific black-legged tick, or deer tick, which also transmits Lyme disease.

These ticks lurk in yards and urban parks, as well as forests where they can stealthily grab onto hikers when they touch tick-infested vegetation. As tick populations boom with growing deer and human populations, the number of people with alpha-gal syndrome is escalating.

Why ticks are blamed for alpha-gal syndrome

There are a few theories on how a tick bite triggers alpha-gal syndrome and why only a small proportion of people bitten develop the allergy. To understand the theories, it helps to understand what happens as a tick starts feeding on you.

When a tick finds you, it typically looks for a warm, dark area to hide and attach itself to your body. Then its serrated teeth chew through your skin with rapid sawing motions.

As it excavates deeper into your skin, the tick deploys a barbed feeding tube, like a miniature drilling rig, and it secretes a biological cement that anchors its head into its new tunnel.

Once secure, the tick activates its pumping station, injecting copious amounts of saliva containing anesthetics, blood thinners and, sometimes, alpha-gal sugars into the wound so it can feed undetected, sometimes for days.

One theory about how a tick bite causes alpha-gal syndrome is linked to the enormous quantity of tick saliva released during feeding, which activates the body’s strong immune response. Another suggests how the skin is damaged as the tick feeds and the possible effect of the tick’s regurgitated stomach contents into the bite site are to blame. Or it may be a combination of these and other triggers. Scientists are still investigating the causes.

What an allergic reaction feels like

The allergy doesn’t begin right away. Typically, one to three months after the sensitizing tick bite, a person with alpha-gal syndrome has their first, disturbing reaction.

Alpha-gal syndrome produces symptoms that range from hives or swelling to crushing abdominal pain, violent nausea or even life-threatening anaphylactic shock. The symptoms usually start two to six hours after a person has ingested a meat product containing alpha-gal.

Due to a general lack of awareness about the allergy, however, doctors can easily miss the diagnosis. A study in 2022 found that 42% of U.S. health care practitioners had never heard of alpha-gal syndrome. A decade ago, people with alpha-gal syndrome might go years before the cause of their symptoms was accurately diagnosed. Today, the diagnosis is faster in areas where doctors are familiar with the syndrome, but in many parts of the country it can still take time and multiple doctor visits.

Unfortunately, with every additional tick bite or exposure to food or products containing alpha-gal, the allergy can increase in severity.

If you think you have alpha-gal syndrome

If you suspect you may have alpha-gal syndrome, the first step is to discuss the possibility with your doctor and ask them to order a simple blood test to measure whether your immune system is reacting to alpha-gal.

If you test positive, the main strategy for managing the allergy is to avoid eating any food product from a mammal, including milk and cheese, as well as other potential triggers, such as more tick bites.

Read labels carefully. Some products contain additives such as carrageenan, which is derived from red algae and contains alpha-gal.

In extreme cases, people with alpha-gal syndrome may need to carry an EpiPen to prevent anaphylactic shock. Reputable websites, such as the CDC and alphagalinformation.org, can provide more information and advice.

Mysteries remain as alpha-gal syndrome spreads

Since alpha-gal syndrome was first formally documented in the early 2000s, scientists have made progress in understanding this puzzling condition. Researchers have connected the allergy to specific tick bites and found that people with the allergy can have a higher risk of heart disease, even without allergy symptoms.

But important mysteries remain.

Scientists are still figuring out exactly how the tick bite tricks the human immune system and why tick saliva is a trigger for only some people. With growing public interest in alpha-gal syndrome, the next decade could bring breakthroughs in preventing, diagnosing and treating this condition.

For now, the next time you are strolling in the woods or in long grasses, remember to check for ticks on your body, wear long sleeves, long pants and tick repellent to protect yourself from these bloodthirsty hitchhikers. If you do get bitten by a tick, watch out for odd allergic symptoms to appear a few hours after your next steak or handful of gummy bears.

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

The latest move came on July 29, 2025, when the Environmental Protection Agency said it planned to rescind its landmark 2009 decision, known as the “endangerment finding,” that greenhouse gases pose a threat to public health and welfare. If that 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 proposal 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.
