In the first of many papers expected from the study, the researchers found that, a year after the ultra-low emissions zone took effect, 2 out of every 5 London students in the study had switched from “passive” to “active” ways of getting to school. So instead of being chauffeured to school by their parents, the students started walking, biking, scootering, or taking public transit. On the other hand, in Luton, which acted as a control group, 1 in 5 made the same switch to modes that got them up and active, but an equal proportion switched to passive travel. But in London’s ultra-low emissions zone, shifting to driving was rare.
The implications of getting kids active, even if it’s just for their pre-class commute, are intuitive but important.
“Walking and biking and scootering to school is better for the child, better for the family, and better for the environment,” said Alison Macpherson, an epidemiologist at York University in Toronto who researches ways to protect and promote the health and safety of children. (She was not involved in the London study.)
“It’s a great way for children to start their day,” she said. “You can imagine just being thrown in a car and thrown out of a car is not the most calming way.” Walking or biking to school, on the other hand, can be calming and conducive to concentration, Macpherson said, potentially even improving academic performance. But perhaps most importantly, at a time when an epidemic of childhood obesity is on the rise worldwide, walking or wheeling to and from school can get kids more active.
Pollution
Earlier versions of these new imported vapes, exemplified by Elf Bar, are beefier and more colorful than Juuls, and are usually single use, despite containing rechargeable lithium-ion batteries. Wired describes a new generation of mostly disposable vapes that, in addition to being extremely cheap and wildly potent, let vapers play games on tiny touchscreens and track their vape’s location on devices that cost as little as $5 apiece. The devices are a grotesque example of electronic waste, viral marketing, and the easily exploitable idiosyncrasies of cross-border commerce in 2024.
But they’re also an example of a bigger trend that’s been gaining momentum for years. If you’ve spent much time on the internet’s burgeoning discount-retail platforms — Temu, TikTok Shop, and Wish, to name a few — disposable vapes with screens and logic boards sound almost reasonable. On Temu, for example, some of the top-selling items in the electronics category are Bluetooth earbuds with touchscreens built in to the case with interfaces of extremely dubious value that can be used to control playback, show screensavers, or just fidget, some of which cost less than $10. There are $4 USB cables with built-in screens to tell you how fast you’re charging; $7 cigarette lighters covered in LED lights and displays; USB hubs that double as external displays; $65 dressers with touchscreens; $48 toasters with software interfaces; $16 rechargeable neck coolers with LED readouts; hundred-dollar motorcycle backpacks with two LCD screens; $18 school backpacks with voice-activated flashing displays.
When used to generate power or move vehicles, fossil fuels kill people. Particulates and ozone resulting from fossil fuel burning cause direct health impacts, while climate change will act indirectly. Regardless of the immediacy, premature deaths and illness prior to death are felt through lost productivity and the cost of treatments.
Typically, you see the financial impacts quantified when the EPA issues new regulations, as the health benefits of limiting pollution typically dwarf the costs of meeting new standards. But some researchers from Lawrence Berkeley National Lab have now done similar calculations—but focusing on the impact of renewable energy. Wind and solar, by displacing fossil fuel use, are acting as a form of pollution control and so should produce similar economic benefits.
Do they ever. The researchers find that, in the US, wind and solar have health and climate benefits of over $100 for every Megawatt-hour produced, for a total of a quarter-trillion dollars in just the last four years. This dwarfs the cost of the electricity they generate and the total of the subsidies they received.
The group succeeded in their demands to water down the pollution standard despite overwhelming evidence showing the devastating impact that vehicle exhaust pollution has on human health and climate, as well as polling showing overwhelming support for the proposed standard.
Such policy “compromise” is often portrayed as important to the cost of living for the average “punter”. But there is no disguising the winners here.
The exemptions, or “re-categorisation” of luxury SUVs into the “light commercial class” included such everyman vehicles as the Mercedes AMG-G 63 (price range $180,000 to $350,000), and the Lexus LX (around $200,000). Most of the other models included have variants that cost well over $100,000.

In a sign of just how low expectations of government are in Australia, most organisations, including environmental groups, welcomed the changes announced on Tuesday, which have garnered the support of the fossil fuel giants such as Toyota, if not the federal Coalition or the Greens.
These groups were at pains to point out how remarkable it is, given Australia’s political situation, that we now stand the chance of actually having vehicle emissions standards. But it is equally remarkable, and testimony to the power of the fossil fuel lobby, that – apart from Russia – Australia is the only western country in the world that doesn’t have them.
Ocean waves crashing on the world’s shores emit more PFAS into the air than the world’s industrial polluters, new research has found, raising concerns about environmental contamination and human exposure along coastlines.
The study measured levels of PFAS released from the bubbles that burst when waves crash, spraying aerosols into the air. It found sea spray levels were hundreds of thousands times higher than levels in the water.
The contaminated spray likely affects groundwater, surface water, vegetation, and agricultural products near coastlines that are far from industrial sources of PFAS, said Ian Cousins, a Stockholm University researcher and the study’s lead author.

He said that the results showed how the chemicals are powerful surfactants that concentrate on the surface of water, which helps explain why they move from the ocean to the air and atmosphere.
“We thought PFAS were going to go into the ocean and would disappear, but they cycle around and come back to land, and this could continue for a long time into the future,” he said.
- In short: Data detailing the air quality at Melbourne's Southern Cross Station has been released for the first time.
- It shows nitrogen dioxide levels in parts of the station have regularly been more than 90 times the guidelines set by the World Health Organization.
- The Victorian government and the station's operator say they've been meeting Australian workplace standards.
I can't help thinking that the author's desire to see "a sustainable Cloud" is misguided. What does "the Cloud" do? What's it for? Why do we need it?
To get at the matter of the Cloud we must unravel the coils of coaxial cables, fiber optic tubes, cellular towers, air conditioners, power distribution units, transformers, water pipes, computer servers, and more. We must attend to its material flows of electricity, water, air, heat, metals, minerals, and rare earth elements that undergird our digital lives. In this way, the Cloud is not only material, but is also an ecological force. As it continues to expand, its environmental impact increases, even as the engineers, technicians, and executives behind its infrastructures strive to balance profitability with sustainability. Nowhere is this dilemma more visible than in the walls of the infrastructures where the content of the Cloud lives: the factory-libraries where data is stored and computational power is pooled to keep our cloud applications afloat.
Industrial contaminants accumulated in Arctic permafrost regions have been largely neglected in existing climate impact analyses. Here we identify about 4500 industrial sites where potentially hazardous substances are actively handled or stored in the permafrost-dominated regions of the Arctic. Furthermore, we estimate that between 13,000 and 20,000 contaminated sites are related to these industrial sites. Ongoing climate warming will increase the risk of contamination and mobilization of toxic substances since about 1100 industrial sites and 3500 to 5200 contaminated sites located in regions of stable permafrost will start to thaw before the end of this century. This poses a serious environmental threat, which is exacerbated by climate change in the near future. To avoid future environmental hazards, reliable long-term planning strategies for industrial and contaminated sites are needed that take into account the impacts of cimate change.
Underpinning the plastic waste crisis is a campaign of fraud and deception that fossil fuel and other petrochemical companies have created and perpetuated for decades.
Through new and existing research, “The Fraud of Plastic Recycling” shows how Big Oil and the plastics industry have deceptively promoted recycling as a solution to plastic waste management for more than 50 years, despite their long-standing knowledge that plastic recycling is not technically or economically viable at scale.
Now it’s time for accountability.
Formed in 2011, REDcycle was a national soft plastics collection and recycling program. It operated across 2,000 Coles and Woolworths supermarkets and some Aldi stores, with customers able to drop off used soft plastics for processing.
Before its collapse in November 2022, the program claimed to collect 5m items a day. Prior to 2018, most of those were sent to China. After that, some were mechanically recycled into road surfacing, bollards, benches and paths in Australia. But a mid-2022 fire at Close the Loop’s Melbourne plant – where soft plastics were turned into an asphalt additive – took away a key recycling pathway. The fire was largely blamed for REDcycle’s suspension along with a “downturn in market demand” exacerbated by the Covid pandemic.
Coles and Woolworths said in April 2023 that REDcycle had been stockpiling soft plastics without their knowledge while the scheme itself claimed it had been holding on to the waste while trying to ride out problems.
The discovery of 11,000 tonnes of stockpiled soft plastic at 44 storage locations across the country led to the establishment of the Soft Plastics Taskforce under the aegis of the Australian Competition and Consumer Commission and chaired by the Department of Climate Change, Energy, the Environment and Water. Its members – Coles, Woolworths and Aldi – were tasked with ensuring the rubbish would not reach landfill.
In March 2023, the taskforce released a plan titled the roadmap to restart, which detailed a phased restart of soft plastic collections in stores from the end of the year. That deadline was not met. The taskforce has, however, “consolidated and safeguarded” REDcycle’s stockpiles and will run a small-scale soft plastics trial collection in the coming months. Just 120 tonnes have been recycled.
