EPA eyes artificial intelligence to speed up chemical safety reviews

The U.S. Environmental Protection Agency plans to deploy artificial intelligence tools to accelerate reviews of new chemicals, but experts warn that gaps in data quality and transparency could undermine the effort.

Ellie Borst reports for E&E News.

In short:

The EPA is developing an “AI Chemist Assistant” and “EcoVault” to help staff more quickly assess chemical safety under the Toxic Substances Control Act by scanning and summarizing scientific data.
While industry groups welcome the move, researchers warn that weak or incomplete datasets, especially proprietary data not publicly available, may lead to unreliable results and limit reproducibility.
The agency’s internal inventory lists over 100 AI-related projects, reflecting a surge in adoption, though current policy requires human verification of all AI-generated conclusions to avoid misinformation.

Key quote:

“The tool is only as good as the data that’s going in.”

— Niki Maslin, chief technology officer and chief artificial intelligence officer, EPA

Why this matters:

The EPA’s chemical review program serves as a gatekeeper between industrial innovation and public exposure to potentially harmful substances. By using AI to accelerate assessments, the agency could potentially move faster, but without rigorous, high-quality data, the process risks becoming less reliable. Many of the chemicals under review are used in products from food packaging to electronics, meaning the consequences of flawed evaluations could ripple through consumer health, occupational safety, and environmental protection. Confidential business data also limits scientific reproducibility and public accountability. As federal agencies lean into AI to manage massive information loads, the tension between speed, secrecy, and safety becomes harder to ignore — especially when toxic exposures often carry long-term, irreversible effects.

Tories pledge to get ‘all our oil and gas out of the North Sea’

Conservative leader Kemi Badenoch has said her party will remove all net zero requirements on oil and gas companies drilling in the North Sea if elected.

Badenoch is to formally announce the plan to focus solely on “maximising extraction” and to get “all our oil and gas out of the North Sea” in a speech in Aberdeen on Tuesday.

Reform UK has said it wants more fossil fuels extracted from the North Sea.

The Labour government has committed to banning new exploration licences. A spokesperson said a “fair and orderly transition” away from oil and gas would “drive growth”.

Exploring new fields would “not take a penny off bills” or improve energy security and would “only accelerate the worsening climate crisis”, the government spokesperson warned.

Badenoch signalled a significant change in Conservative climate policy when she announced earlier this year that reaching net zero would be “impossible” by 2050.

Successive UK governments have pledged to reach the target by 2050 and it was written into law by Theresa May in 2019. It means the UK must cut carbon emissions until it removes as much as it produces, in line with the 2015 Paris Climate Agreement.

Now Badenoch has said that requirements to work towards net zero are a burden on oil and gas producers in the North Sea which are damaging the economy and which she would remove.

The Tory leader said a Conservative government would scrap the need to reduce emissions or to work on technologies such as carbon storage.

Badenoch said it was “absurd” the UK was leaving “vital resources untapped” while “neighbours like Norway extracted them from the same sea bed”.

In 2023, then Prime Minister Rishi Sunak granted 100 new licences to drill in the North Sea which he said at the time was “entirely consistent” with net zero commitments.

Reform UK has said it will abolish the push for net zero if elected.

The current government said it had made the “biggest ever investment in offshore wind and three first of a kind carbon capture and storage clusters”.

Carbon capture and storage facilities aim to prevent carbon dioxide (CO2) produced from industrial processes and power stations from being released into the atmosphere.

Most of the CO2 produced is captured, transported and then stored deep underground.

It is seen by the likes of the International Energy Agency and the Climate Change Committee as a key element in meeting targets to cut the greenhouse gases driving dangerous climate change.

Dogs and drones join forest battle against eight-toothed beetle

Sean Gallup/Getty Images A close up shot of Ips Typographus, a light brown hairy beetle with three front legs visible one slightly extended out. It is walking along the bark of a logged spruce tree.

It is smaller than your fingernail, but this hairy beetle is one of the biggest single threats to the UK’s forests.

The bark beetle has been the scourge of Europe, killing millions of spruce trees, yet the government thought it could halt its spread to the UK by checking imported wood products at ports.

But this was not their entry route of choice – they were being carried on winds straight over the English Channel.

Now, UK government scientists have been fighting back, with an unusual arsenal including sniffer dogs, drones and nuclear waste models.

They claim the UK has eradicated the beetle from at risk areas in the east and south east. But climate change could make the job even harder in the future.

The spruce bark beetle, or Ips typographus, has been munching its way through the conifer trees of Europe for decades, leaving behind a trail of destruction.

The beetles rear and feed their young under the bark of spruce trees in complex webs of interweaving tunnels called galleries.

When trees are infested with a few thousand beetles they can cope, using resin to flush the beetles out.

But for a stressed tree its natural defences are reduced and the beetles start to multiply.

“Their populations can build to a point where they can overcome the tree defences – there are millions, billions of beetles,” explained Dr Max Blake, head of tree health at the UK government-funded Forestry Research.

“There are so many the tree cannot deal with them, particularly when it is dry, they don’t have the resin pressure to flush the galleries.”

Since the beetle took hold in Norway over a decade ago it has been able to wipe out 100 million cubic metres of spruce, according to Rothamsted Research.

‘Public enemy number one’

As Sitka spruce is the main tree used for timber in the UK, Dr Blake and his colleagues watched developments on continental Europe with some serious concern.

“We have 725,000 hectares of spruce alone, if this beetle was allowed to get hold of that, the destructive potential means a vast amount of that is at risk,” said Andrea Deol at Forestry Research. “We valued it – and it’s a partial valuation at £2.9bn per year in Great Britain.”

There are more than 1,400 pests and diseases on the government’s plant health risk register, but Ips has been labelled “public enemy number one”.

The number of those diseases has been accelerating, according to Nick Phillips at charity The Woodland Trust.

“Predominantly, the reason for that is global trade, we’re importing wood products, trees for planting, which does sometimes bring ‘hitchhikers’ in terms of pests and disease,” he said.

Forestry Research had been working with border control for years to check such products for Ips, but in 2018 made a shocking discovery in a wood in Kent.

“We found a breeding population that had been there for a few years,” explained Ms Deol.

“Later we started to pick up larger volumes of beetles in [our] traps which seemed to suggest they were arriving by other means. All of the research we have done now has indicated they are being blown over from the continent on the wind,” she added.

The team knew they had to act quickly and has been deploying a mixture of techniques that wouldn’t look out of place in a military operation.

Drones are sent up to survey hundreds of hectares of forest, looking for signs of infestation from the sky – as the beetle takes hold, the upper canopy of the tree cannot be fed nutrients and water, and begins to die off.

But next is the painstaking work of entomologists going on foot to inspect the trees themselves.

“They are looking for a needle in a haystack, sometimes looking for single beetles – to get hold of the pioneer species before they are allowed to establish,” Andrea Deol said.

In a single year her team have inspected 4,500 hectares of spruce on the public estate – just shy of 7,000 football pitches.

Such physically-demanding work is difficult to sustain and the team has been looking for some assistance from the natural and tech world alike.

When the pioneer Spruce bark beetles find a suitable host tree they release pheromones – chemical signals to attract fellow beetles and establish a colony.

But it is this strong smell, as well as the smell associated with their insect poo – frass – that makes them ideal to be found by sniffer dogs.

Early trials so far have been successful. The dogs are particularly useful for inspecting large timber stacks which can be difficult to inspect visually.

The team is also deploying cameras on their bug traps, which are now able to scan daily for the beetles and identify them in real time.

“We have [created] our own algorithm to identify the insects. We have taken about 20,000 images of Ips, other beetles and debris, which have been formally identified by entomologists, and fed it into the model,” said Dr Blake.

Some of the traps can be in difficult to access areas and previously had only been checked every week by entomologists working on the ground.

The result of this work means that the UK has been confirmed as the first country to have eradicated Ips Typographus in its controlled areas, deemed to be at risk from infestation, and which covers the south east and east England.

“What we are doing is having a positive impact and it is vital that we continue to maintain that effort, if we let our guard down we know we have got those incursion risks year on year,” said Ms Deol.

And those risks are rising. Europe has seen populations of Ips increase as they take advantage of trees stressed by the changing climate.

Europe is experiencing more extreme rainfall in winter and milder temperatures meaning there is less freezing, leaving the trees in waterlogged conditions.

This coupled with drier summers leaves them stressed and susceptible to falling in stormy weather, and this is when Ips can take hold.

With larger populations in Europe the risk of Ips colonies being carried to the UK goes up.

The team at Forestry Research has been working hard to accurately predict when these incursions may occur.

“We have been doing modelling with colleagues at the University of Cambridge and the Met Office which have adapted a nuclear atmospheric dispersion model to Ips,” explained Dr Blake. “So, [the model] was originally used to look at nuclear fallout and where the winds take it, instead we are using the model to look at how far Ips goes.”

Nick Phillips at The Woodland Trust is strongly supportive of the government’s work but worries about the loss of ancient woodland – the oldest and most biologically-rich areas of forest.

Commercial spruce have long been planted next to such woods, and every time a tree hosting spruce beetle is found, it and neighbouring, sometimes ancient trees, have to be removed.

“We really want the government to maintain as much of the trees as they can, particularly the ones that aren’t affected, and then also when the trees are removed, supporting landowners to take steps to restore what’s there,” he said. “So that they’re given grants, for example, to be able to recover the woodland sites.”

The government has increased funding for woodlands in recent years but this has been focused on planting new trees.

“If we only have funding and support for the first few years of a tree’s life, but not for those woodlands that are 100 or century years old, then we’re not going to be able to deliver nature recovery and capture carbon,” he said.
