Public health and environmental groups are taking legal action aimed at forcing the Environmental Protection Agency (EPA) to issue new standards to limit levels of soot, smoke, and other airborne particles linked to thousands of premature deaths each year.
The groups sent a "notice of intent to sue" letter to EPA Administrator Lisa Jackson giving EPA 60 days to address EPA's failure to conduct a mandatory five-year review of the 2006 particulate matter standards, which should have been completed yesterday.
These limits, called the national ambient air quality standards, drive cleanup of pollution across the nation and, by law, must be set to protect public health. The Clean Air Act requires that EPA determine if the standards meet that requirement by reviewing the science every five years.
The letter was filed by Earthjustice on behalf of the American Lung Association and National Parks Conservation Association. In 2006, the Bush Administration ignored recommendations by its science advisors for stronger protections and adopted the current weak particulate matter standards. In 2009, as a result of a legal challenge brought by these groups, a federal appeals court ruled that these standards were deficient and sent them back to EPA for corrective action.
Since then the Obama EPA has failed to propose new standards although the science confirms that particulate matter pollution in the U.S. continues to cause thousands of premature deaths and tens of thousands of hospital visits every year.
"Scientists, medical professionals, the courts and the general public have agreed for years that deadly soot levels are unacceptable for Americans. Our actions today demand that EPA adopt the legally-required air quality standards that will save thousands lives," said Paul Cort, staff attorney for Earthjustice.
"The scientific evidence keeps growing to show that particulate matter is a deadly air pollutant--and that the current standards fail to protect us from that threat," said Janice E. Nolen, Assistant Vice President, National Policy and Advocacy, for the American Lung Association. "We need EPA to follow the law and finish the job."
"By adopting more protective soot standards EPA will help clear the air in our national parks at the same time it is making the air healthier for all Americans to breath," said Mark Wenzler, Vice President for Climate and Air Quality at National Parks Conservation Association.
Airborne particulate matter is comprised of tiny particles of smoke, soot, metals and other chemical compounds emitted from sources like power plants, factories, and diesel trucks. Scientists say particulate matter which can penetrate deep into our lungs, is one of the most toxic forms of air pollution. They estimate that it is responsible for tens of thousands of premature deaths nationwide every year. It is also linked to the aggravation of respiratory illnesses, such as asthma, bronchitis, and chronic obstructive lung disease (COPD), and to heart disease, and lung cancer. Particulate matter is also responsible for much of the haze that clouds many of our cities and parklands.
The group's leader called for rejecting "attempts to curtail funding for renewable energy projects" along with "the bullying efforts by the USA and others to weaken policies and regulations to combat climate change."
Nearly 10 months after President Donald Trump ditched the Paris Agreement for a second time, a leading human rights organization on Wednesday urged the remaining parties to the landmark treaty to defy his dangerous example when they come together next week for the United Nations Climate Change Conference in Belém, Brazil.
"Amnesty International is urging governments to resist aligning with the Trump administration's denial of the accelerating climate crisis and instead demonstrate true climate leadership," said the group's secretary general, Agnès Callamard, in a statement. "In the face of President Trump's rejection of science coupled with the intensified lobbying for fossil fuels, global leaders must redouble their efforts to take urgent climate action—with or without the US."
Callamard, who plans to attend COP30, stressed that "the global climate crisis is the single biggest threat to our planet and demands a befitting response. The effects of climate change are becoming more pronounced across the whole world. We confront increasingly frequent and severe storms, wildfires, droughts, and flooding, as well as sea-level rise that will destroy some small island states."
"COP30 in Brazil presents an opportunity for collective resistance against those trying to reverse years of commitments and efforts to keep global warming below 1.5°C," she continued, referring to a primary goal of the Paris Agreement. "The fact that levels of carbon dioxide in the atmosphere soared by a record amount last year should ring alarm bells for world leaders at COP30."
Further elevating fears for the future, the UN Environment Programme warned Tuesday that Paris Agreement parties' latest pledges to cut greenhouse gas emissions—officially called Nationally Determined Contributions (NDCs)—could push global temperatures to 2.3-2.5°C above preindustrial levels, up to a full degree beyond the treaty's key target for this century.
Greenpeace demands world leaders agree on a global response plan at #COP30 as a new major UN report warned the global temperature is projected to rise to 2.3-2.5°C above pre-industrial era global temperatures, putting the Paris Agreement limit of 1.5°C at risk in the short-term.

Oil Change International highlighted in a report released last week that the United States—which is responsible for the biggest share of planet-heating pollution since the Industrial Revolution—plus Australia, Canada, and Norway are now "overwhelmingly responsible for blocking global progress on phasing out oil and gas production."
The group's global policy lead, Romain Ioualalen, said that "10 years ago in Paris, countries promised to limit warming to 1.5°C, which is impossible without putting an end to fossil fuel expansion and production. The rich countries most responsible for the climate crisis have not kept that promise. Instead, they've poured more fuel on the fire and withheld the funds needed to put it out."
"The fact that a handful of rich Global North countries, led by the United States, have massively driven up their oil and gas production while people around the world suffer the consequences is a blatant mockery of justice and equity," Ioualalen added. He called on governments attending COP30 "to deliver a collective roadmap for equitable, differentiated fossil fuel phaseout dates, and address the systemic barriers preventing Global South countries from transitioning to renewable energy, including finance."
Some experts are concerned that Trump—who's pursuing a pro-fossil fuel agenda that includes but is far from limited to exiting the Paris Agreement—may interfere with the talks, even though a White House official confirmed to Reuters last week that he doesn't plan to send a delegation to Belém.
The official said that Trump made his administration's views on global climate action clear in his September speech at the UN General Assembly—during which the president said the fossil fuel-driven crisis was "the greatest con job ever perpetrated on the world," and the scientific community's predictions about the global emergency "were wrong" and "were made by stupid people."
Pointing to Trump's global tariff war that was debated before the US Supreme Court on Wednesday, the official added that "the president is directly engaging with leaders around the world on energy issues, which you can see from the historic trade deals and peace deals that all have a significant focus on energy partnerships."
As CNN reported Tuesday:
This practice of linking trade and climate so closely is an innovation of the Trump administration, said Kelly Sims Gallagher, dean of the Fletcher School at Tufts University who worked on US climate negotiations with China for the Obama administration.
In the absence of US leadership, she said that China, which is the world's top emitter, may seek to assume more of a prominent, steering role at the talks. The European Union is also likely to take a strong role, though internal rifts have emerged within the EU regarding how aggressively to cut its own emissions.
While Gallagher and other experts who spoke with CNN don't necessarily expect that COP30 will feature the same kind of disruptive behavior that Trump engaged in during last month's International Maritime Organization meeting to delay a new set of global regulations to slash shipping industry emissions, they acknowledged that it is possible. Already, the Tufts professor suggested, Trump's abandonment of the Paris treaty appears to be having an impact.
"I think there's an undeniable fact, which is that with the US withdrawal for a second time, it's definitely seeming to undermine ambition," Gallagher said. "I think it's just getting harder to make the case that global ambition is going to rise without pretty substantial engagement from the United States."
Despite not sending a high-level delegation to the COP30 Climate Summit in Brazil, the presence of the US will still be felt by negotiators there. The US will be the elephant in the room, and could seek to disrupt the talks from afar, depending on how they're trending... www.cnn.com/2025/11/04/c...

Callamard argued Wednesday that those attending COP30 "must push back against attempts to curtail funding for renewable energy projects and resist the bullying efforts by the USA and others to weaken policies and regulations to combat climate change."
"Humanity can win if states commit at COP30 to a full, fast, fair, and funded fossil-fuel phase-out and just transition to sustainable energy for all, in all sectors, as recently confirmed by the International Court of Justice's recent advisory opinion," she said. "These commitments must go hand-in-hand with a significant injection of climate finance, in the form of grants, not loans, from states that are the worst culprits for greenhouse gas emissions."
"Crucially, states must take steps to protect climate activists and environmental defenders," the Amnesty leader added. "This is the only way to secure climate justice and protect the human rights of billions of people."
According to an annual Global Witness report published in September, at least 142 people were killed and four were confirmed missing last year for "bravely speaking out or taking action to defend their rights to land and a clean, healthy, and sustainable environment," bringing the total to at least 2,253 land defenders slaughtered or disappeared since the group started tracking such cases in 2012.
“To limit new weapons development in China or Russia, one of the best things the US can do is maintain the taboo on testing and ratify the Comprehensive Test Ban Treaty," said one expert.
More than a dozen US senators on Wednesday urged President Donald Trump to abort plans for a resumption of nuclear weapons testing, a call that came as Russian President Vladimir Putin directed his senior officials to draft proposals for possible new nuke tests in response.
“We write to you today to express grave reservation about any action to resume nuclear weapons testing," 14 Democratic senators led by Sens. Jacky Rosen (D-Nev.) and Martin Heinrich (D-NM), ranking member of the Senate Select Committee on Intelligence, said in a letter to Trump.
"We request that you personally provide clarification," the lawmakers added. "The decision to resume nuclear weapons testing would be geopolitically dangerous, fiscally irresponsible, and simply unnecessary to ensure the ability of the United States to defend itself."
Sen. Ed Markey (D-Mass.)—who signed the letter—also introduced emergency legislation last week aimed at preventing Trump from resuming nuclear weapons tests.
Although no country is known to have tested a nuclear weapon since North Korea last did so in 2017, Trump last month ordered the Pentagon to prepare for a resumption of reciprocal testing.
“The United States has more Nuclear Weapons than any other country,” Trump falsely wrote on social media. “Because of other countries testing programs, I have instructed the Department of War to start testing our Nuclear Weapons on an equal basis.”
TASS reported Wednesday that Putin instructed the Russian Foreign Ministry, Defense Ministry, intelligence agencies, and civilian bureaus to submit proposals "on the possibility of preparing for nuclear weapons tests" in the event that other countries resume testing.
Russia has not tested a nuclear weapon in its modern history. The former Soviet Union's final nuclear test took place in 1990 and the successor Russian state has adhered to a moratorium ever since.
Last week, Congresswoman Dina Titus (D-Nev.) introduced a bill to prohibit new US nuclear weapons testing. Titus accused Trump of putting "his own ego and authoritarian ambitions above the health and safety of Nevadans."
Supporting Titus' bill, Tara Drozdenko, director of the Global Security Program at the Union of Concerned Scientists, said in a statement Wednesday that “there is no good reason for the United States to resume explosive nuclear testing and it would actually make everyone in this country less safe."
"We have so much to lose and so little to gain from resuming testing," she continued. "New explosive testing by the United States would be to make a political statement, with major consequences: It would shatter the global freeze on nuclear testing observed by all but North Korea and give Russia, China, and other nuclear powers the green light to restart their own nuclear testing programs."
“The United States has not conducted a nuclear detonation test since 1992," Drozdenko noted. "Even those advocating for testing acknowledge there is no scientific need to test to maintain the US nuclear arsenal. In fact, Energy Secretary Chris Wright recently said that the updated systems can be tested without conducting full nuclear detonations."
“To limit new weapons development in China or Russia, one of the best things the US can do is maintain the taboo on testing and ratify the Comprehensive Test Ban Treaty," she added. "This treaty with on-site verification measures would be the best way to ensure that countries are not clandestinely testing nuclear weapons.”
The United States and Soviet Union came dangerously close to nuclear war on multiple occasions during the Cold War, most notably amid the 1962 Cuban Missile Crisis and, later, during then-President Ronald Reagan's first administration in the early 1980s.
Weeks after becoming the first country to develop nuclear weapons in 1945, the United States waged the world's only nuclear war, dropping atomic bombs on the defenseless Japanese cities of Hiroshima and Nagasaki and killing hundreds of thousands of people, mostly civilians.
According to the International Campaign for the Abolition of Nuclear Weapons, Russia leads the world with 5,449 nuclear warheads in its arsenal, followed by the US with 5,277 warheads, China with around 600, France with 290, and the United Kingdom with 225. Four other nations—India, Pakistan, Israel, and North Korea—also have nuclear arsenals of between 50-180 warheads each.
If funding is not restored to the Low Income Home Energy Assistance Program, said one expert, "pipes will freeze, people will die."
As more than 40 million households that rely on federal food aid are forced to stretch their budgets even further than usual due to the Trump administration only partially funding the Supplemental Nutrition Assistance Program under a court order, many of those families are facing another crisis brought on by the government shutdown: a loss of heating support that serves nearly 6 million people.
President Donald Trump has sought to eliminate the $4 billion Low Income Home Energy Assistance Program (LIHEAP), proposing zero funding for it in his budget earlier this year and firing the team that administers the aid.
Though Congress was expected to fund the program in the spending bill that was supposed to pass by October 1, Democrats refused to join the Republican Party in approving government funding that would have allowed healthcare subsidies to expire and raised premiums for millions of families, and Trump and congressional Republicans have refused to negotiate to ensure Americans can afford healthcare.
The government shutdown is now the longest in US history due to the standoff, and energy assistance officials have joined Democratic lawmakers in warning that the freezing of LIHEAP funds could have dire consequences for households across the country as temperatures drop.
Mark Wolfe, executive director of the National Energy Assistance Directors Association (NEADA), told the Washington Post on Wednesday that even if the shutdown ended this week, funding would not reach states until early December—and more families will fall behind on their utility bills if lawmakers don't negotiate a plan to open the government soon.
“You can imagine in a state like Minnesota, it can get awfully cold in December. We’re all just kind of waiting, holding our breath.”
"People will fall through the cracks,” Wolfe told the Post. “Pipes will freeze, people will die.”
With heating costs rising faster than inflation, 1 in 6 households are behind on their energy bills, and 5.9 million rely on assistance through LIHEAP.
The Department of Health and Human Services generally released LIHEAP funds to states in the beginning of November, but energy assistance offices in states where the weather has already gotten colder have had to tell worried residents that there are no heating funds.
Officials in states including Vermont and Maine have said they can cover heating needs for families who rely on LIHEAP for a short period of time, and some nonprofit groups, like Aroostook County Action Program in northern Maine, have raised money to distribute to households.
But states and charities can't fill the need that LIHEAP has in past years. Minnesota's Energy Assistance Program received $125 million from the federal government last year that allowed 120,000 families to heat their homes.
Aroostook County Action Program has provided help to about 200 households in past years, while LIHEAP serves about 7,500 Maine families.
The state has already received 50,000 applications for heating aid and would be preparing to send $30 million in assistance in a normal year.
“You can imagine in a state like Minnesota, it can get awfully cold in December,” Michael Schmitz, director of the program, told the Post. “We’re all just kind of waiting, holding our breath.”
NEADA told state energy assistance officials late last month to plan on suspending service disconnections until federal LIHEAP funds are released, and US Rep. Don Beyer (D-Va.) led more than four dozen lawmakers in urging utilities to suspend late penalties and shutoffs for federal workers who have been furloughed due to the shutdown.
States reported that they'd begun receiving calls from people who rely on LIHEAP as Americans across the country went to the polls on Tuesday and delivered Democratic victories in numerous state and local races.
The president himself said the shutdown played a "big role" in voters' clear dissatisfaction with the current state of the country.
