Dust from car brakes and tyres will still pollute city air even when the vehicle fleet has gone all-electric, a report has warned. Fragments of microplastics from tyres, road surfaces and brakes will also flow into rivers, and ultimately into the sea, government advisers say. Ministers say they want to pass standards to improve tyres and brakes.
But critics say they need to go further by developing policies to lure people out of private cars. The government’s Air Quality Expert Group said particles from brake wear, tyre wear and road surface wear directly contribute to well over half of particle pollution from road transport.
They warn: “No legislation is currently in place specifically to limit or reduce [these] particles. So while legislation has driven down emissions of particles from exhausts, the non-exhaust proportion of road traffic emissions has increased.”
They say the percentage of pollutants will get proportionally higher as vehicle exhausts are cleaned up more.
Environment Minister Thérèse Coffey said : “The documents published today make clear that it is not just fumes from car exhaust pipes that have a detrimental impact on human health but also the tiny particles that are released from their brakes and tyres. Emissions from car exhausts have been decreasing through development of cleaner technologies – and there is now a need for the car industry to find innovative ways to address the challenges of air pollution from other sources”.

- ‘How do I charge an electric car without a driveway?’
Mike Hawes, chief executive of the Society of Motor Manufacturers and Traders, said: “The industry is committed to improving air quality and has already all but eliminated particulate matter from tailpipe emissions. Brake, tyre and road wear is a recognised challenge as emissions from these sources are not easy to measure.”
The document chimes with a recent report warning that electric cars won’t offer a complete solution to mobility. It said even self-driving electric cars would produce pollution and congest the roads. The key was to reduce the use of cars by getting people on to less-polluting forms of transport, said Prof Jillian Anable, one of the authors of the report.
She said: “For many years ministers have adopted the principle of trying to meet demand by increasing road space. They need to reduce demand instead.”
The UK transport department said it was spending £6bn on buses, walking and cycling – and £50bn on roads.
Supporters of electric cars say the report may be flawed because when you lift your throttle foot in an electric vehicle, the car slows itself and there is less need to brake.
This week, contractors for the US government’s Bureau of Lands Management (BLM) ran wild mustangs from distances as far as 3-5 miles in temperatures that crept into the 90’s Fahrenheit. Helicopters targeted smaller groups and relentlessly chased them. A small foal stopped running, it suffering from exhaustion and had to be roped and walked in. 94 horses were finally captured with 2 animals dying.
One of the saddest parts of the roundups is when the trailers leave packed with horses who will never experience freedom again.

TRIPLE B ROUNDUP DAY 2 REPORT: 75 wild horses were rounded up and removed yesterday and there was 1 death – a foal was euthanized because of “extremely weak tendons”.
We also received clarifications on the 3 deaths from Wednesday. The BLM originally attributed the deaths to “Pre-existing condition, starvation, emaciation and weakness.” By the next day, the BLM changed its explanation of the deaths. Now the pre-existing conditions that prompted the BLM to “euthanize” the horses are attributed to a lost eye, broken leg, laceration. Read our report here: https://wildhor.se/TripleB2019
These actions are an utterly disgusting and inhumane treatment that is happening across wide areas of the US range-land and which is destroying one of the great cultural icons of a great country, for thousands of these wild beasts are now being held in holding yards at a substantial cost with a substantial going for slaughter and unseen, unknown to most of the public.
Tuesday, June 18, and from my fairly high bay-window vantage point, a number of notable weather and astronomical observations were in evidence…
The day started off greyish, quickly brightening up through the morning. From late-morning until late into the afternoon it was very humid. During this same period, far out towards the seaward horizon, lay a thick band of brown, polluted air that was quite distinct with the unaided eye, probably arising from the dirty fuel that most ships still use.
Late-afternoon and the sky clouded over. (Mid-evening and the cruise ship Queen Elizabeth 2 sailed down Channel making for St.Peters Port). Late evening, and very low over the far south-eastern horizon the full moon – minus a day, slowly rose from out the blackness – it probably being the most blood-orange-coloured moon I have ever witnessed in my entire life! Fantastic!
As it slowly rose in the heavens, it was consumed by the storm clouds of a fierce electric storm which radar showed to have developed over the mid-Channel on air coming out of the Cherbourg peninsula, this drifting north-eastwards and clipping Sussex and Kent, there being much intense fork lightning, thunder, a stiffening breeze accompanying the intense rain that arrived just after 11pm, the roads resembling rivers. The storm then slipping away some 40 minutes later. What a spectacle!
Despite its English name of Common Butterwort this plant is rare in southern England, indeed, this tiny colony is the only colony in East Sussex. After a while today hunting within the Ashdown Forest SSSI we eventually re-discovered it again. Still only six plants – the same as four years ago but, all these tiny plants in flower or are about to.
Saturday June 1st and what a stunning start to the month – perhaps it will turn out to be a proverbial ‘flaming June?’ During the morning we walked up over Seaford Head. The first image shows the difference where Sussex Wildlife Trust have winter-cut the invasive tor grass and where not; note the cut, flower-rich lower RH side of image against the rank LH side of the image.
On the bare chalk area on the Hawks Brow area, noticed at least 6 vertical seems of flint within the chalk, flint normally having been deposited horizontally within the bedding of the chalk. Note one of these peculiar features running from right of centre at bottom of image towards right of person, the adjacent chalk being more eroded towards the cliff edge and so highlighting it better.
Attended the Southease Open Gardens event. Some idyllic houses and beautiful gardens, all set-off in a quintessentially English fete-like atmosphere, accompanied by the brilliant The Maestro Big Band from Newhaven playing 40’s swing music.
The town of Seaford was today between 5pm and 6-15pm, treated to a flying display by 4 Dakotas transport aircraft, these circulating repeatedly over the town, seafront and cliffs!
7-50am, and the Britannia is steaming past Britannia – well to precise at this moment, St.Leonards and is relatively speaking, close in at 13 miles and on passage from Bergen in Norway and making for Southampton for an 11am docking. She is easily identified by her twin funnels.
The MV Britannia is a cruise ship of the P&O Cruises fleet. She was built by Fincantieri at its shipyard in Monfalcone, Italy. At 143,000 GT, Britannia is the largest of seven ships currently in service with P&O Cruises and she is also the flagship of the fleet. She officially entered service on 14 March 2015, and was named by Queen Elizabeth II. Britannia features a 94 metres (308 ft) Union Flag on her bow, the largest of its kind in the world. A beautiful looking ship but cruising wouldn’t be my choice – all that frivolous consumption would be at odds with my environmental beliefs!
Length: 330 m Capacity: 3,647 passengers Cost: £473 million Speed: 21.9 knots (40.6 km/h; 25.2 mph) @ 136 rev/min.
During this month of May, I have twice visited the RSPB’s reserve at Dungeness to bird watch – something I haven’t done per se for many years – my former work and time always requiring me to look at the ‘bigger scene.’ Presumably due to our changing climate, these two outings were something of an update for me personally. Firstly, I saw a pair of Great Egret fly across a marsh, these, I have never seen in this country. Awhile later I witnessed 5 hobbys in view at once! These used to be fairly rare summer visitors but are now more numerous. These falcons have spectacular powers of flight, they being able to catch swallows and dragonflies.
Just before I was about to get out of bed this morning, another new birding experience – that of laying in bed and watching swifts hawking high above the big oak immediately at the end of the garden – lazy twitching!

A team of researchers from the University of Oxford, Fera Science, Sylva Foundation and the Woodland Trust has calculated the true economic cost of ash dieback in Britain which are staggering:
- The total cost of ash dieback to the UK is estimated to be £15 billion.
- Half of this (£7 billion) will be over the next 10 years.
- The total cost is 50 times larger than the annual value of trade in live plants to and from Britain, which is the most important route by which invasive plant diseases enter the country.
- There are 47 other known tree pests and diseases that could arrive in Britain and which may cost an additional £1 billion or more.
The predicted costs arise from clearing up dead and dying trees and in lost benefits provided by trees, e.g. water and air purification and carbon sequestration. The loss of these services is expected to be the biggest cost to society, while millions of ash trees also line Britain’s roads and urban areas and clearing up these dangerous trees will cost billions of pounds.
Dr Louise Hill, researcher at Plant Sciences at the University of Oxford and lead author of the study, said: “The numbers of invasive tree pests and diseases are increasing rapidly, and this is mostly driven by human activities, such as trade in live plants and climate change. Nobody has estimated the total cost of a tree disease before and we were quite shocked at the magnitude of the cost to society. We estimate the total may be £15 billion – that’s a third more than the reported cost of the foot-and-mouth disease outbreak in 2001. The consequences of tree diseases for people really haven’t been fully appreciated before now.”
Dr Nick Atkinson, senior conservation adviser for the Woodland Trust and co-author of the paper, said: “When ash dieback first entered the country, no one could have fully predicted the devastating impact it would have on our native habitats. To see how this has also affected our economy speaks volumes for how important tree health is, and that it needs to be taken very seriously. It is clear that to avoid further economic and ecological impacts, we need to invest more in plant bio-security measures. This includes better detection, interception and prevention of other pests and diseases entering the country. We need to learn from past mistakes and make sure our countryside avoids yet another blow.”
The scientists say that the total cost could be reduced by replanting lost ash trees with other native trees, but curing or halting the disease is not possible. They advise that the government’s focus now has to be on preventing introductions of other non-native diseases to protect our remaining tree species.
Background. Ash dieback is a fungal disease, originally from Asia, which is lethal to Europe’s native ash trees. It was first found in Britain in 2012 and is thought to have been brought to the UK years earlier on infected imported ash trees. It is expected to kill 95-99% of ash trees in Britain.
