Introducing Ulez was my hardest decision as mayor of London – but now we know its astonishing impact | Sadiq Khan

Published

When I introduced London’s clean air zone – the ultra-low emission zone (Ulez) – more than seven years ago, no city had ever attempted anything quite like it. At the time, the scheme in central London provoked fierce opposition. When I decided to expand it – first in 2021, to inner London, and then again in 2023 to the whole city, making it the biggest clean-air zone in the world – my detractors were louder still. I had, they claimed, declared war on drivers in blind pursuit of a policy that may not even work. All the mainstream political parties, including my own, were opposed. In recent years, though, those critics have gone quiet.

There is now a mountain of evidence to show that the Ulez has slashed air pollution and improved air quality across London, and research published by Imperial College London earlier this year showed that this is already saving lives. Between 2019 (when I first introduced the Ulez) and 2024, estimated deaths associated with air pollution in the capital fell by around 40%. But a new, independent study published by Queen Mary University of London today goes further still, showing how – by helping to clean up the capital’s air – the Ulez is improving the lungs and lives of London’s children.

Young children are the first to feel the impact of air pollution. They breathe faster than adults, and more often through their mouths, allowing more pollution to pass into their bodies. Their heads are lower to the ground, too, meaning they’re closer to vehicle exhausts pumping out poisonous chemicals. And, because they’re still growing, long-term exposure to air pollution can do lasting damage to their development, leading to problems such as asthma, chronic obstructive pulmonary disease (COPD) and lung cancer when they’re older.

One of the first places I visited when I was elected mayor 10 years ago was the Sir John Cass’s Foundation primary school in Aldgate, now known as The Aldgate school. On the school’s roof, I joined children who were growing a garden. As they proudly showed me what they’d planted, the kids told me about how much they loved spending time outdoors. But, speaking to their teachers, it was obvious that they were worried about the air the children were breathing. The school was next to one of inner London’s busiest roads and, while an air-quality monitor had been installed in the playground, they were powerless to stop toxic fumes from the traffic passing by. As a father of two daughters myself, I remember trying to imagine how those children’s parents must have felt, knowing that every day their kids were being exposed to a danger that they couldn’t control.

I’ve never forgotten that day. Because, for me, meeting those kids confirmed what the fight for cleaner air was really about: not punishing motorists or making money, but protecting the lives of London’s most vulnerable people.

The Ulez has already had an astonishing impact on London’s air. According to research done by King’s College London, without additional action, it would take almost two centuries to get levels of one of the most toxic chemicals in our air – nitrogen dioxide (NO2) – within legal limits. But, last year, we announced that we’d done it already – 184 years earlier than predicted. Now, we’re beginning to see what our success means for London’s children.

The independent study published by scientists at Queen Mary today is one of the most comprehensive of its kind. In it, researchers tracked the lung growth of more than 3,400 children in Luton and central London, beginning in 2019 and concluding five years later. The results are remarkable.

Before we introduced the Ulez, London’s filthy air meant that children in the capital had significantly poorer lung function than children in Luton. But, across the five-year period when the Ulez was in force, children’s exposure to NO2 fell twice as fast in London as it did in Luton. And, when scientists measured lung function again at the end of the study, young Londoners’ lungs had caught up. This shows that cutting air pollution doesn’t just help Londoners being born today – it can help children whose lungs have already been stunted by toxic air to recover, proving that it’s never too late to act. Over the course of the research, the proportion of children in London with clinically impaired lung function fell from 14% to 9%.

Introducing and expanding the Ulez involved some incredibly difficult decisions. I never took them lightly, but I knew that – as mayor – I could not stand by while Londoners young and old lost their lives to a problem it was within my power to solve. For years, politicians and pundits opposed to the Ulez have cynically sought to turn questions of public health into a crude culture war. Today, though, it’s clear that we’re winning the battle against toxic air in the capital – and it’s London’s children who are reaping the rewards.

Two months ago, I returned to the roof garden of The Aldgate school. It was just over 10 years since my first visit and, getting ready to garden with a group of smiling children, I felt a strange sense of deja vu. This time, though, something was different. Back in 2016, the air-quality monitor in the playground showed that levels of nitrogen dioxide in the air were exceeding legal limits. But, when they were measured again last year, they’d fallen by 48%. As a result, the kids I met didn’t have to think twice about what a game of football outside may mean for their health, and their parents didn’t have to worry about whether walking to school may stunt the growth of their lungs.

Today, you’ll find stories like this in schools across the capital: kids who are breathing easier and parents who are sleeping better because they no longer have to worry about the damage being done by toxic air. The Ulez has been the toughest fight of my political life, but I have no regrets. Though there’s more to be done, it’s clear that cleaning up the capital’s air has changed young Londoners’ lives for the better – and nothing could matter more than that.

Number of cloned number plates on UK roads at record high, data shows | Transport

Published

on


The number of reported “cloned” vehicles involved in offences on UK roads has reached a record high, official data shows.

More than 11,400 drivers contacted the DVLA last year after being issued with fines for offences they said they did not recognise or accept responsibility for – most of which are believed to be down to cloning, where a number plate is copied fraudulently on similar vehicles to avoid enforcement cameras.

The number of complaints about misattribution was 9% higher than in 2024 and almost double the figure recorded in 2018, according to the RAC motoring organisation, which analysed data obtained under freedom of information requests.

The rising figures underscore concerns about the number of illegal number plates in use, allowing criminals to evade detection and dangerous drivers to avoid being caught.

Although drivers should provide number plate suppliers with the V5C vehicle logbook and proof of identity, an investigation last year uncovered more than 130 official suppliers in the UK willing to sell cloned versions, which allow drivers to dodge police and congestion charges.

Cloning vehicles has left many innocent car owners having to struggle to prove they were not responsible when enforcement camera images apparently caught their vehicle committing offences.

A parallel concern is the use of “ghost” plates which are designed to be unreadable by the UK’s 18,000 automatic number plate recognition (ANPR) cameras, which enforce safety measures such as speed limits or lane closures on smart motorways.

The RAC said the UK needed to overhaul an outdated and poorly regulated number plate system. Its head of policy, Simon Williams, said: “If number plate suppliers were carrying out all the checks they’re supposed to, it would be much harder for dodgy drivers to buy cloned plates in the first place. It’s only when a fine arrives at a vehicle keeper’s home address that they realise someone else is driving around using their vehicle’s number plate illegally.”

He said that more also needed to be done to catch drivers with ghost plates, “whether that’s more police officers being equipped with handheld devices that can detect if plates are unreadable, updating ANPR cameras and introducing higher security standards for number plates and for those who produce them”.

The government last month said there would be a new nationwide crackdown on illegal number plates, with funding from the Department for Transport for a new roads policing team. A new National Roads Policing Coordination Centre would share intelligence as well as trialling new technology such as specialised goggles to detect number plates that have been designed to be unreadable by cameras.

Drivers using an incorrectly displayed number plate can be fined up to £1,000.

A Department for Transport spokesperson said: “We’re cracking down on illegal number plates with significant investment in a new roads policing team and innovative tech to stamp out the scourge of cloned numberplates.

“Illegal number plates help facilitate crime, and we are supporting the police to work with the DVLA to make it easier to report these crimes and support victims through a new digital tool.”

‘A big responsibility’: Clifton Suspension Bridge master hails £7.6m renovation | Bristol

Published

on


The job does not give the holder age-old perks such as the right to drive sheep across the great structure, but the title “bridge master” does have a certain ring to it.

“I don’t tend to say I’m the bridge master when I’m at a party,” said Tristan Ralph, the current holder of the title. “But people do seem to know and bring it up. It’s a job less ordinary, isn’t it? It’s a Victorian sounding title and people are really, really interested.”

There is, however, nothing ceremonial about the title. Ralph is in charge of maintaining and running the Clifton Suspension Bridge, a UK feat of engineering, without any public money.

“It does feel a big responsibility,” said Ralph. “When the chairman of the trustees rang to say we’d like you to do it, you suddenly feel the pressure. It’s so famous and people in Bristol, quite rightly, are proud and almost possessive of it. Bristolians think: ‘It’s our bridge.’”

The bridge master – and the not-for-profit charity the Clifton Suspension Bridge Trust – have the task of maintaining the bridge “in perpetuity”. “I’m a temporary custodian,” Ralph said. “When I’m finished, I have to make sure it is handed on in just [as] good a condition or better than I inherited it.”

Ralph, a bridge engineer by profession, was speaking to mark the conclusion of a large refurbishment project that has taken two and a half years and involved hand-painting more than 4,000 original iron chain links and installing an energy-efficient lighting system. It has cost about £7.5m. “It’s been a big job,” he said. “But it’s come pretty much bang on budget, which is rare these days.”

That is important because, to many visitors’ surprise, the bridge does not receive public funding. “The upkeep of the bridge, the running of it, the salary costs and everything are all paid only by our toll money,” said Ralph. “People think that we might get something from local or central government. But, no, it’s just the toll money.”

Motorised vehicles – including motorcycles – pay £1 to cross the bridge. There is no charge for pedestrians, cyclists or horse riders. As well as being a beautiful structure, it is also a vital part of Bristol and North Somerset’s transport system.

Ralph said: “It draws the tourists in. We get visitors from hundreds of countries every year but primarily, it’s still a vital piece of local infrastructure. If the bridge wasn’t here, the difference it would make to Bristol traffic would be incredible. We average over 8,000 vehicles a day still. Maintaining it as a transport link is utterly vital.”

The end of the refurbishment does not mean Ralph can rest on his laurels and spend more time hobnobbing with members of the Bridge Owners Forum.

“In a few years, we’ll need to paint the underside of the bridge. The under-bridge gantry unit itself will be replaced over the coming years. So there’s always something. We need to keep on top of things. It’s like your house or your car. If you just ignore it, don’t do things for a couple of years, they start breaking down.”

As in most walks of life, the climate emergency is a challenge Ralph and the trust are having to face. “We were monitoring the bridge daily in the summer with the very hot weather. And maybe if the bridge was being designed today, there would be a little bit more robustness around wind.”

The prevailing south-west wind is not usually a problem and the bridge rarely has to close but if it blows directly through the Avon Gorge it can be more difficult. “We need to keep an eye at both the magnitude of any wind events but also their frequency,” Ralph said.

And there is no sign that its days are numbered, largely because the Victorians did not skimp. Ralph said: “There are three layers of chains. The original Brunel design only had two, but because it went from a timber design to a cast-iron deck, they upped it to three.

“There’s a little bit of comfort in there. Today there might be pressure to say, well, can you keep it to two, but in Victorian times they did like to add a little bit of meat on the bones.

“It doesn’t have a finite life. There’s no end date in our plans. We all just keep it going in the highest standards as we can. It’s in really good condition as long as we keep doing what we need to do, keep our attention on it and don’t let things drift. Forever is a long time but there’s no reason why we have any need to worry at the moment.”

Uber begins self-driving robotaxi trial in Manchester | Uber

Published

on


Uber has begun a trial of autonomous vehicles on the streets of Manchester as it looks to bring robotaxis to cities around the UK.

The first self-driving cars are operating, using the technology of its partner firms Pony and Verne, with whom Uber recently launched Europe’s first autonomous taxi service in the Croatian capital, Zagreb.

Uber said it was “excited to take this first step toward making this technology accessible to people across the UK”.

In social media posts, Verne said it had “started our autonomous vehicle testing in Manchester”, while Pony said there were “plans to bring robotaxis to the city” and that testing was under way.

The tests involve the company mapping the streets of the city in north-west England with a safety driver behind the wheel and no passengers.

Limited passenger services started last month in London, but with a safety driver in the front seat of cars supplied by Wayve under Transport for London’s licensing rules for private hire vehicles.

The next steps are unclear. Opposition from Uber drivers, their unions and the capital’s politicians to the rollout of robotaxis is mounting. The GMB and ADCU unions have both said thousands of drivers jobs will be lost and have called for help for those affected.

A critical report from London assembly’s transport committee this week called for the government to devolve authority over autonomous taxi services.

It said there was “considerable uncertainty about many of the claimed benefits of autonomous passenger vehicles”, and fears over the impact on public transport and congestion, as well as safeguarding and accessibility for disabled passengers.

There has been no official application to launch passenger services in Manchester so far, and the vehicles are operating under government licence via the Driver and Vehicle Standards Agency (DVSA) and the Department for Transport.

A spokesperson for Transport for Greater Manchester said it wanted the city’s taxis to be the safest in the country.

“New technologies play an increasingly important role in the growth of our city region,” they said. “But they need to be introduced responsibly, safely and with real thought about what it means for our residents.

“Although no applications have been made to operate driverless taxis in the Greater Manchester, we’re aware of potential interest from companies to do so.

“Safety will always be our top priority, and we will need strong assurances that no vehicles will operate on our roads that pose any risk to residents.”

Uber said it expected to offering robotaxi trips in as many as 15 cities worldwide by the end of 2026, mainly in the US and the Middle East.
