Pollution

The ULEZ restrictions are actually not all that strict, especially from the perspective of us here at an electric vehicle publication – most diesel and petrol (gasoline)-powered cars made within the last 10 and 20 years respectively qualify, despite that they still create significant tailpipe pollution.

Also, there are exemptions available for delivery vehicles, buses and so on.

Nevertheless, despite these exemptions, a recent report released by the city of London shows how well the ULEZ has worked at lowering pollution in London and making everyone healthier.

The report points out that two of the most dangerous aspects of vehicle emissions – nitrogen oxides, which are responsible for smog formation, and PM2.5, which are tiny particles that irritate the lungs – have dropped by almost a third compared to if ULEZ hadn’t been implemented, in only the few years that the policy has been in place.

Specifically, NO2 is 27% lower and PM2.5 is 31% lower in outer London. Nitrogen oxides (which includes both NO and NO2) as a whole are down 14%.

Some areas have seen even more significant declines, like Central London, the most densely populated area. It has seen a drop in NO2 levels of 54%.

All in all, 99% of air quality monitors around London have showed a reduction in pollution, so the new rules have benefitted everyone.

The biggest chemical cover up in history. PFAS has polluted the entire global water system. Now, potentially dangerous forever chemicals are being found in the entire US population.

A new study was released in recent days that should have been newsworthy, but it escaped the media's attention in Australia.

It showed Australian police are world leaders at arresting climate and environmental protesters.

According to the study, more than 20 per cent of all climate and environment protests in Australia involve arrests, which is more than three times the global average (6.3 per cent).

Australia's arrest rate was the highest of 14 countries in the global study.

It's higher than policing efforts in the United Kingdom (17.2 per cent), Norway (14.5 per cent), and the United States (10 per cent).

The research makes it clear that Australia's political leaders have joined the "rapid escalation" of efforts to criminalise and repress climate and environmental protest, while sovereign states globally fail to meet their international agreements and emissions targets.

When you read the Bristol University study alongside the special rapporteur's position paper and the EDO paper, you get a pretty good sense of how the clampdown on climate and environmental activism actually works, and why it's occurring.

Collectively, the reports discuss an issue that links political donations and pressure from fossil fuel companies, governments writing new laws and harsher penalties for climate and environmental activists, federal and state policing agencies being put to work to enforce the new laws, and legal systems and courts being used to bed them down.

And hanging over the entire political problem is the question of the "pricing mechanism" and the role it plays in a society like ours.

When you look at this issue dispassionately, you'll see that we're witnessing a nasty global battle over the attempt to have the negative externalities of fossil fuels properly reflected in the market prices of the products of fossil fuel companies.

Every major English water company has reported data suggesting they’ve discharged raw sewage when the weather is dry – a practice which is potentially illegal.

BBC News has analysed spills data from nine firms, which suggests sewage may have been discharged nearly 6,000 times when it had not been raining in 2022 - including during the country’s record heatwave.

Helen Wakeham from the EA says the BBC’s methodology is, in fact, “more generous” to the companies than the EA’s.

Commenting on the results of the BBC’s investigation in general she said: “I'm not surprised, these networks haven't been invested in for decades. That investment needs to take place.”

In May the UK’s top engineers and medical professionals warned in a public report the risk from human faecal matter in our rivers will increase without changes to the network and how we build our cities.

Dr David Butler, professor of water engineering at the University of Exeter, and co-author of the report, said investment from water companies has “not really been up to scratch”.

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.

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.
