Postcard from California: State and feds head for showdown over electric cars

Of California’s dozens of landmark laws to curb climate-heating greenhouse gases and health-threatening air pollution, none is more ambitious than the rule that by 2035 all new passenger cars and trucks sold must be zero-emission vehicles (ZEVs) that run on electricity.

Contrary to the inflammatory rhetoric of its critics, the ZEV rule is not a total ban on gasoline or diesel vehicles. In 2035 and beyond, Californians could still drive their existing gasoline cars or buy used ones.

But by electrifying the state’s fleet over time, the rule would steadily reduce tailpipe emissions, which are by far the largest source of greenhouse gases in California. It would also slash emissions of smog-forming air contaminants, averting thousands of heart attacks and strokes and hundreds of thousands of asthma attacks.

The Institute of Transportation Studies at the University of California at Davis calls the ZEV rule “one of the most daring and controversial air quality policies ever adopted.” Eleven other states have signed on, extending its reach to 40% of the US population.

California lawmakers adopted the current version of the ZEV rule in 2022. But to implement it, the state needed a waiver from the US Environmental Protection Agency (EPA), allowing California to set stricter emissions standards than federal rules.

In one of the last major acts of the Biden administration, the EPA granted the waiver Dec. 18. It was a huge milestone in California’s clean-energy transition – but it also set up a high-stakes showdown between the state and the incoming Trump administration.

Study indicates “persistent, damaging” effects of glyphosate herbicide exposure on brain health

By Carey Gillam

Exposure to a widely used weed killing chemical could be having “persistent, damaging effects” on brain health, according to a new study.

The study, published Wednesday in the Journal of Neuroinflammation, found that laboratory mice exposed to glyphosate herbicide developed significant brain inflammation, a condition associated with neurodegenerative diseases such as Alzheimer’s. The researchers, many who are associated with a neurodegenerative disease research center at Arizona State University (ASU), said the symptoms continued even long after exposure ended.

“This work is yet another step forward in understanding the impact of this widely used herbicide on the brain,” lead ASU researcher Ramon Velazquez said. “But more research is needed to determine the impact that glyphosate has on the brain since most Americans are exposed to this herbicide on a daily basis.” Velazquez noted that the work is particularly important given the increasing incidence of cognitive decline in the aging population, particularly in rural communities where glyphosate is used in farming.

Glyphosate is the most commonly used herbicide globally – made popular by Monsanto Co as the active ingredient in its Roundup brand, among others. It has been used so extensively by farmers, homeowners and industrial and municipal users for so long that it is considered ubiquitous – found in food, water and in human urine samples. A 2022 report by a unit of the Centers for Disease Control and Prevention (CDC) said more than 80% of urine samples drawn from children and adults in a US health study contained glyphosate.

Several authors of the new paper were also part of a team that published a prior, related study that examined the impact of glyphosate when it infiltrates the brain.

Opinion: Revealing the toxic lobbying power of Bayer

By Hans van Scharen

Big fossil-fuel companies like Shell, Exxon, BP or Total are not your trusted source to go to for solid advice on how to urgently prevent the climate from changing ever faster. But for halting the spread of cancer and all kinds of degenerative diseases, helping farmers out of their collective socioeconomic nightmares, combating hunger or how to avoid a further collapse of biodiversity, policymakers find it completely normal to engage with powerful agrochemical companies like Bayer and BASF.

Yet these companies produce many chemical products that are bad for our health, for the environment and increasingly for democracy itself, as shown by Corporate Europe Observatory’s new report Bayer’s Toxic Trails.

Whether it’s over glyphosate, GMOs, or global warming, we show how it attempts to capture public policy to pursue its private interests.

Bayer tries to legitimize this expensive lobby by being more or less transparent about it and calling it “political advocacy“. In fact, it is thanks to it’s deep pockets and economic clout capable of changing laws and regulations which should serve the general interest. Bayer simply wants to maintain monopolistic control of the seed and pesticides markets, fights off regulatory challenges to its toxic products, tries to limit legal liability, and exercises political influence.

First there is the element of global market power and ever increasing concentration, making them an essential part of a small club of global Food Barons. Just four of these multinationals – Bayer, BASF, Corteva and Syngenta – control over 65% of global trade in pesticides and at least half of the world’s seed trade. That represents a multi billion euro market, co-control over the world’s production of food, and very much related, loads of deep political influence on agricultural and environmental policies.

Just for the record: the successful lobby campaign to take down the Farm2Fork Strategy, a crucial part of the EU Green Deal, was the work of these companies, their consultancies and trade associations like Croplife (with a little help from their political friends, of course).

Bayer and allies were also spearheading the campaign to prolong the EU authorization for glyphosate with another 10 years, despite a wealth of scientific indications that show the product is a disaster for health, biodiversity, soil and water.

“Defend or be damned” – How a US company uses government funds to suppress pesticide opposition around the world

By Carey Gillam, Margot Gibbs and Elena DeBre

In 2017, two United Nations experts called for a treaty to strictly regulate dangerous pesticides, which they said were a “global human rights concern”, citing scientific research showing pesticides can cause cancers, Parkinson’s disease, Alzheimer’s, and other health problems.

Publicly, the industry’s lead trade association dubbed the recommendations “unfounded and sensational assertions”. In private, industry advocates have gone further.

Derogatory profiles of the two UN experts, Hilal Elver and Baskut Tuncak, are hosted on an online private “social network” portal for pesticide company employees and a range of influential allies.

Members of the network can access a wide range of personal information about hundreds of individuals from around the world deemed a threat to industry interests, including US food writers Michael Pollan and Mark Bittman, the Indian environmentalist Vandana Shiva and the Nigerian activist Nnimmo Bassey. Many profiles include personal details such as the names of family members, phone numbers, home addresses and even house values.

The profiling is part of a broad campaign – that was financed partly with US taxpayers dollars – to downplay pesticide dangers, discredit opponents, and undermine international policymaking harmful to the pesticide industry, according to court records, emails and other documents obtained by the non-profit newsroom Lighthouse Reports in an investigative reporting collaboration with The New Lede, the Guardian, and other international media partners.

The efforts were spearheaded by a “reputation management” firm in Missouri called v-Fluence. The company, founded by former Monsanto executive Jay Byrne, provides self-described services that include “intelligence gathering”, “proprietary data mining” and “risk communications”.

The revelations demonstrate how industry advocates established a “private social network” to counter resistance to pesticides and genetically modified (GM) crops in Africa, Europe and other parts of the world, while also denigrating organic and other alternative farming methods. More than 30 current government officials are on the membership list of the private network, most of whom are from the US Department of Agriculture (USDA).

Elver, who is now a university research professor and a member of a United Nations food security committee, said public money would have been better spent on scientific research into the health impacts of pesticides than on profiling people such as herself.

“Instead of understanding the scientific reality, they try and shoot the messenger. It is really hard to believe,” she said.

Author Michael Pollan’s profile portrays him as an “ardent opponent” of industrial agriculture and (GM) crops and a proponent of organic farming. His profile includes a long list of criticisms and details such as the names of his siblings, parents, son and brother-in-law.

“It’s one thing to have an industry come after you after publishing a critical article. This happens all the time in journalism,” Pollan said. “But to have your own government pay for it is outrageous. These are my tax dollars at work.”

New study finds potentially harmful pathogens traveling high in the atmosphere

By Douglas Main

A wide variety of fungi and bacteria, including E. coli and other potential human pathogens, have been found high in the atmosphere where they can travel for hundreds to thousands of miles before falling back to Earth, according to new research.

Air samples collected from between roughly a half mile and two miles in altitude (1 kilometer to 3 kilometers) near Tokyo, Japan, carried bacterial species known to be capable of causing health problems such as food poisoning and skin infections, researchers said.

The study, published this week in Proceedings of the National Academy of Sciences, reported that while most of the microbes detected were likely dead, testing confirmed more than ten species of microbes collected from high in the sky were alive. Those were particularly hardy strains, including several found to be antibiotic resistant. One of these, a type of ubiquitous bacteria not known to normally infect humans, was resistant to five different antibiotic drugs.

The discovery represents a “paradigm shift,” said Xavier Rodó, the study’s lead author and head of the health and climate program at the Barcelona Institute for Global Health. “From the public health standpoint it opens the door to really viewing the air and the atmosphere as an environment we need to pay attention to.”

The scientists used atmospheric measurements and computer models in concluding that most of the material found over Tokyo was coming from an agricultural region in northeast China, where row crops and livestock are raised. The study authors hypothesized that some of the bacteria, including the antibiotic-resistant ones, derived from sewage used to fertilize the land, and from the soil itself.

Widespread use of antibiotics with industrialized livestock production could plausibly introduce antibiotic resistance bacteria into the atmosphere as bits of soil and manure can be aerosolized and blow away on the wind, said David Smith, a NASA microbiologist who wasn’t involved in the study.

Besides microbes, the researchers also found significant quantities of many elements normally found in soil, such as sulfur and sodium, as well as aluminum, potassium, iron, and calcium.

They also detected zinc sulfate nanoparticles, which they hypothesized are coming from fertilizer use, as well as trace quantities of zirconium and hafnium, metals mined in China but not in Japan.

Congress should follow science and reject Bayer push to block lawsuits

By Nathan Donley

Millions of American users of glyphosate-based Roundup have likely assumed the Environmental Protection Agency (EPA) would never have approved the pesticide unless it was safe.

But the science-based truth has never been as cut and dried as the EPA and Bayer, which bought Roundup maker Monsanto in 2018, have made it sound. In a series of trials across the country, juries – and the public – have learned that despite the safety claims by Bayer and the EPA, hundreds of studies by independent scientists link glyphosate herbicides to serious health harms, including cancer.

Even though Bayer maintains that its glyphosate products are safe and not carcinogenic, the company has thus far agreed to pay out more than $10 billion in settlement costs to tens of thousands of glyphosate users suffering from non-Hodgkin lymphoma (NHL), and thousands of lawsuits remain.

In an effort to block further litigation, the chemical giant has turned its focus to getting federal and state legislation passed to block Roundup users from suing the company for damages. According to a recent Washington Post article, Bayer helped draft language for a legislative measure that would limit the types of lawsuits brought by the Roundup users. That measure is included in the US House of Representatives version of the 2024 Farm Bill, which is slated to be finalized later this year. The company has also been pushing lawmakers in several states to pass similar measures.

Key to Bayer’s messaging to legislators is that, because glyphosate is EPA-approved, research showing its harms should be rejected. But the process by which the EPA approved glyphosate decades ago has never been reassuring to independent scientists such as myself.

Postcard from California: The human cost of living with wildfires

By Bill Walker

The toll of wildfire in California is staggering: In the last 10 years, wildfires have burned more than 13.6 million acres of the state and taken the lives of 144 people, including 15 firefighters. The state estimates property damages from the more than 93,000 wildfires in those years at nearly $250 billion.

But sobering as those statistics are, they don’t measure the full cost to Californians from living with increasingly deadly and destructive wildfires.

A new study, led by researchers from the Fielding School of Public Health at the University of California at Los Angeles (UCLA), calculated that from 52,480 to 57,710 Californians died prematurely from exposure to wildfire smoke between 2008 and 2018. The study, published June 7 in the peer-reviewed journal Science Advances, estimated the economic impact of those lost lives at between $432 billion and $456 billion.

“Climate change, forest mismanagement and an expansion of the wildland-urban interface have led to worsening wildfires across California, and with those fires come smoke pollution and increasing health impacts from air pollution exposure,” Rachael Connolly, a staff researcher at the UCLA Fielding School and lead author of the study, said in a statement. “This is the first research exploring how that chronic, long-term smoke exposure affects people across the state.”

The wildland-urban interface refers to zones where people live near forests or other undeveloped areas at greater risk of wildfire. The high cost and scarcity of housing in coastal cities is pushing more and more Californians to move inland, swelling the population in areas more likely to burn.

Biofuels manufacturing found to be a significant source of hazardous air pollution

By Dana Drugmand

Hazardous air pollutants emitted in the manufacturing of biofuels is nearly as bad as air pollution stemming from oil refineries, and for several types of dangerous pollutants such as formaldehyde the emissions from biofuel production are far greater, a new report finds.

The assessment, which was conducted by researchers with the environmental watchdog group Environmental Integrity Project (EIP), looked at emissions generated by 275 ethanol, biodiesel and renewable diesel facilities in the United States. The researchers found that the facilities frequently violated air pollution permits while at the same time benefiting from legal exemptions and federal policy supports such as fuel-blending mandates.

As the biofuels industry continues expanding with more than 30 new facilities under construction or proposed, the industry should be seen as a threat to public health, the report warns. Stronger regulatory oversight from the Environmental Protection Agency (EPA) is needed, according to EIP.

“Despite its green image, the biofuels industry releases a surprising amount of hazardous air pollution that puts local communities at risk – and this problem is exacerbated by EPA’s lax regulation” Courtney Bernhardt, EIP director of research, said in a statement.

According to the EIP report released on Wednesday, biofuels manufacturing generated 12.9 million pounds of hazardous air pollutants in 2022. That compares to 14.5 million pounds of hazardous air pollutants emitted by oil refineries that year, according to data from EPA’s Toxic Release Inventory.

Emissions from biofuel factories were significantly higher than oil refineries for four types of hazardous pollutants – formaldehyde, acetaldehyde, acrolein, and hexane, according to the EIP report. In 2022, biofuel facilities reported releases of nearly 7.7 million pounds of hexane, over 2.1 million pounds of acetaldehyde, 235,125 pounds of formaldehyde, and 357,564 pounds of acrolein. By comparison, oil refineries that year emitted 2.6 million pounds of hexane, 10,420 pounds of acetaldehyde, 67,774 pounds of formaldehyde, and zero pounds of acrolein.

US regulator accused of “egregious” misconduct in PFAS testing of pesticides

By Carey Gillam

Documents obtained from the US Environmental Protection Agency (EPA) indicate the agency may have presented false information to the public about testing for harmful contaminants in pesticides, according to allegations being made by a watchdog group and a former EPA research fellow.

The claims come almost a year to the day after the EPA issued a May 2023 press release that stated the agency found no per- and polyfluoroalkyl substances (PFAS) in testing of samples of certain insecticide products. The press release contradicted a published study by the former EPA researcher that had reported finding PFAS in the same pesticide products.

PFAS contamination is a hot topic in environmental and public health circles because certain types of PFAS are known to be very hazardous for human health, and world governments and public health advocates are pushing to sharply limit exposure to these types of chemicals. Accurate testing for PFAS contamination is key to regulating exposure, making the accuracy and transparency of EPA testing a critical issue.

The allegations that the EPA incorrectly reported some PFAS test results were made Tuesday by the nonprofit group Public Employees for Environmental Responsibility (PEER), led by former EPA employees.

PEER Director of Scientific Policy Kyla Bennett said that the organization obtained pesticide product testing data from the EPA through a Freedom of Information Act (FOIA) request. The documents they received back from the EPA showed the agency had indeed found PFAS in the tested products, directly contradicting the press release the agency had issued.

“It’s pretty outrageous,” said Bennett. “You don’t get to just ignore the stuff that doesn’t support your hypothesis. That is not science. That is corruption. I can only think that they were getting pressure from pesticide companies.”

Joining in the allegations is environmental toxicologist Steven Lasee, who authored the 2022 study that the EPA challenged. Lasee is a consultant for state and federal government agencies on PFAS contamination projects and participated as a research fellow for the EPA’s Office of Research and Development from February 2021 to February 2023.

California paraquat ban moves forward

By Carey Gillam

California has moved a step closer to banning the controversial weed killing chemical paraquat after a key state legislative committee on Thursday allowed the measure to proceed.

The ban would take effect Jan. 1, 2026, outlawing the “use, manufacture, sale, delivery, holding, or offering for sale in commerce” of any pesticide product that contains paraquat. The bill provides for a process that allows state regulators to reevaluate paraquat and potentially reapprove it with or without new restrictions.

A chief concern cited by backers of the bill is research linking chronic paraquat exposure to Parkinson’s disease, an incurable and debilitating brain disease considered a top cause of death in the United States.

Several thousand farmers, agricultural workers and others are suing paraquat maker Syngenta, alleging they developed Parkinson’s because of long-term chronic effects of paraquat.

“California is the breadbasket of the nation. Farm workers put food on our table, and we should do everything we can to make their jobs safer,” California Assemblymember Laura Friedman said. “No one should run the risk of chemical exposure on the job leading to their contracting Parkinson’s disease.”

Friedman, who partnered with the Environmental Working Group (EWG) to introduce the measure, said it passed “not only because banning paraquat is the right thing to do,” but also because there are “readily available, safer, affordable alternatives.”

The movement of the bill out of the appropriations committee this week now sets it up for a vote by the full Assembly next week. A vote has to be completed by Friday, May 24, in order for the measure to be moved to the state Senate for consideration. A majority of 80 Assembly members is needed to keep the bill alive.
