The party is hoping they can integrate the public health message with grassroots concern, but leave behind conspiracy theories

Chellie Pingree remembers when she moved to Maine as a teenager in the 1970s – she was one “hippie” among thousands in the back-to-the-land movement, when baby boomers fled to the sticks to revitalize small organic farms.

Today, she’s a Democratic US Representative for Maine, but still knee-deep in the organic movement. And she’s starting to see a lot of new faces – many pulled in by the Make America Healthy Again (Maha) movement, largely led by the Trump administration’s health secretary, Robert F Kennedy Jr.

Critics warn of climate danger as president in Texas claims change will save companies and consumers billions

Donald Trump said his administration is “terminating” Biden-era regulations holding oil and gas companies accountable for large leaks of planet-warming methane during a rally in Lubbock, Texas, on Tuesday evening.

“Tonight, I’m officially terminating Biden’s expensive and unnecessary methane regulations to save consumers and energy producers,” Trump said, lifting what he called “crippling regulations on methane that caused prices to skyrocket” for small oil and gas operators. The change would save consumers and energy producers $45bn and unlock 210m barrels of oil, he said, which is equivalent to about 10 days of US petroleum consumption.

Environmentalists decry move that relaxes requirements on automakers to control pollution from gas-powered cars

The Trump administration on Monday announced it was slashing clean car rules that had been aimed at reducing planet-heating emissions and boosting electric vehicles.

The move, which was criticized by environmentalists, relaxes requirements on automakers to control pollution from gasoline-powered cars and light trucks for model years 2022 through 2031.

Environmental Protection Agency asked firm to choose rules it wanted for dicamba, then put the choices in a proposed federal rule

The EPA allowed pesticide giant Bayer to pick from a menu of regulation options for the controversial and destructive weedkiller dicamba, newly released internal agency documents show.

The documents provide an unusually clear look into the process of developing pesticide regulations, which is typically done out of public view. It shows in detail how the EPA asked Bayer which regulations it wanted, received a response from Bayer, then put Bayer’s choices into a proposed federal rule.

Energy Transfer, whose CEO is a major Trump donor, named as biggest single methane producer in new rankings

Down a short gravel track in a largely nondescript corner of Louisiana sits a gas processing facility, operated by a company whose chief executive is a major donor to Donald Trump. It may be the largest emitter of methane in the US.

The Energy Transfer site, located near the city of Shreveport, is named as the biggest single “super emitter” in new rankings of US oil and gas operations for the largest releases of methane, a powerful greenhouse gas that is rapidly overheating our planet, according to a new UCLA study, which is based on satellite data.

Trump’s EPA strips itself of regulation ability, gutting Clean Air Act in what experts say is a gift to planet polluters

On the heels of the hottest summer ever recorded in the US, the Trump administration has said it will erase any limits on emissions from coal and gas plants that are dangerously heating up our planet.

The US Environmental Protection Agency said it will strip itself of its ability to regulate greenhouse gas emissions coming from power plants under the Clean Air Act, removing a key tool to address the climate crisis.

Lee Zeldin says ‘low-volume release’ of flammable chemicals is most likely amid fears of explosion at Orange county facility near Disneyland

Government officials in Orange county, California, have warned that an overheated chemical tank “will fail” and could result in a chemical explosion in the area, the Environmental Protection Agency administrator said on Sunday.

“We’re being told that the tank will fail, but there are different scenarios as to what that means,” Lee Zeldin, told CNN’s State of the Union on Sunday. Zeldin, a former Republican congressman with no prior experience in environmental policy, was chosen by Trump as the head of the EPA.

Lawsuit says rescission of endangerment finding – which ruled greenhouse gases threaten public health – was illegal

A coalition of 24 states, alongside a dozen cities and counties, has sued the Trump administration over its decision to revoke the bedrock scientific determination underpinning virtually all US climate regulations.

The new lawsuit, filed in the US Court of Appeals for the District of Columbia Circuit on Thursday, is being led by the states of Massachusetts, California, New York and Connecticut. It argues that the Environmental Protection Agency’s February rescission of the 2009 endangerment finding – which the White House described as the “single largest deregulatory action in US history” – was illegal.

The Quapaw Nation is the only US Native community to carry out a cleanup of one of the country’s worst sites of environmental contamination

They call this land the Laue. In the late 1800s, part of these 200 acres of grassland inside the Quapaw Nation were allotted to tribal citizen Charley Quapaw Blackhawk. After forcing dozens of tribes into Indian territory before the civil war, the US government then parceled out reservations and property to individual members. It was part of the government’s attempt to “civilize” Native Americans by turning them into private, not communal, landholders and yeoman farmers in the model of Thomas Jefferson’s ideal citizen.

Yet, for the last century, little grew on the Laue. Half of it was buried beneath towering mounds of toxic rock known as chat piles. The waste rock, laced with chemicals, was left after miners extracted millions of tons of lead and zinc from the Tri-State Mining District, where the valuable ores stretched across Kansas, Missouri and Oklahoma between 1891 and the 1970s. By 1983, the Environmental Protection Agency (EPA) had designated 40 sq miles that include nearly all the Quapaw Nation as the Tar Creek Superfund site, joining the EPA’s list of the most contaminated places in the country. Informally called a “megasite”, Tar Creek remains one of the largest and most complex environmental disasters in the country.

EPA rolls back rules as chemical firms claim provisions in RMP protection system too expensive to implement

The Trump administration is slowly dismantling the federal disaster management system that protects the nation from chemical catastrophes, such as fires and explosions at high-risk facilities.

The US Environmental Protection Agency’s Response Management Program (RMP) requires more than 12,500 high-risk facilities to develop protocols to prevent catastrophes, or limit fallout, and was largely designed to protect workers, first responders, and fence-line communities.

EPA found only 27 of 219 plants needed upgrades; 71 later got exemptions as Donald Trump scrapped mercury limits

Almost all coal-fired power plants in the US had the ability to comply with rules limiting their emission of dangerous pollutants such as mercury that can cause brain damage in children. Despite this, Donald Trump’s administration decided to demolish the standards anyway.

Last week, the Trump administration said it is loosening restrictions on air toxins from mercury, lead and other heavy metals that are released by coal plants. Such pollution is known to be neurotoxic and has been linked to irreversible brain damage in children and infants, as well as heart disease and cancer in adults.

Without federal climate regulation, fossil fuel industry may be more vulnerable to local lawsuits

The Trump administration’s repeal of a foundational climate determination could clear a path for new litigation and policies targeting big oil, legal experts say.

Earlier this month, Donald Trump’s Environmental Protection Agency (EPA) finalized a rule revoking the “endangerment finding”, a 2009 determination that established that greenhouse gases threaten public health and welfare. The move eliminated federal limits on climate-warming emissions from motor vehicles, and is expected to extend to all other pollution sources.

Critics accuse administration of ‘cooking the books’ by claiming US would save $1.3tn from climate finding reversal

The Trump administration claims its latest move to gut climate regulations and end all greenhouse gas standards for vehicles will save Americans money. But its own analysis indicates that the new rule will push up gas prices, and that the benefits of the rollback are unlikely to outweigh the costs.

On Thursday, the president and his environmental secretary, Lee Zeldin, announced the finalized repeal of the endangerment finding, a legal determination which underpins virtually all federal climate regulations. He claimed the rollback would save the US $1.3tn by 2055.

Senators said repeal was ‘particularly troubling’ and was counter to EPA’s mandate to protect human health

More than three dozen Democratic senators have begun an independent inquiry into the US Environmental Protection Agency (EPA) following a huge change in how the agency measures the health benefits of reducing air pollution that is widely seen as a major setback to US efforts to combat the climate crisis.

In a regulatory impact analysis, the EPA said it would stop assigning a monetary value to the health benefits associated with regulations on fine particulate matter and ozone. The agency argued that the estimates contain too much uncertainty.

Corteva will discontinue a mixture of Agent Orange and glyphosate, but another of its herbicides will still use Vietnam war-era defoliant

The chemical giant Corteva will stop producing Enlist Duo, a herbicide considered to be among the most dangerous still used in the US by environmentalists because it contains a mix of Agent Orange and glyphosate, which have both been linked to cancer and widespread ecological damage.

The US military deployed Agent Orange, a chemical weapon, to destroy vegetation during the Vietnam war, causing serious health problems among soldiers and Vietnamese residents.

This article was amended on 9 February 2026 to add comment from a Corteva spokesperson.
