Diesel exhaust fumes are causing the biggest health catastrophe since the Black Death, a campaign group has claimed, as new figures show air pollution limits for the whole year have been breached in just eight days in London.

European Union limits demand that maximum hourly nitrogen dioxide (NO2) concentrations are not exceeded for more than 18 hours a year – yet Putney High Street, in west London, had recorded its 19th hour breaching the limits during Friday morning’s rush hour, the London Air Quality Network said.

Oxford Street, where legal limits for the toxic gas for the whole of 2015 were breached in just two days, has almost certainly broken the limit again but the monitoring equipment is currently being repaired. Campaigners say that the Government must do more to tackle air pollution which has been linked to respiratory and heart problems.

Simon Birkett, founder and director of campaign group Clean Air in London, said it was breathtaking that toxic air pollution in the capital had breached the legal limit for the whole calendar year within the first few days of 2016. Mr Birkett also called on all the candidates in the mayoral elections to pledge to ban diesel exhausts from the most polluted areas by 2020.

He said: “Worse, several air pollution monitors have been vying for the dubious honour of recording the first officially monitored breach of the nitrogen dioxide (NO2) legal limit in the world in 2016.”

He added that Oxford Street would have been first if it had not been offline, and warned that scientists said London would tend to have the highest nitrogen dioxide concentrations in the world because of its diesel pollution.

“This shocking start to the 60th anniversary year of the world’s first Clean Air Act in 1956 illustrates the scale of Boris’ [Johnson’s] failure to reduce diesel fumes, which are the main source of NO2 at street level, and protect hundreds of thousands of people on our busiest shopping streets.

“Put simply, diesel exhaust is the biggest public health catastrophe since the Black Death”.

Alan Andrews, lawyer for ClientEarth, which announced last month it would take the Government back to court over air quality, said: “Its failure to deal with illegal levels of air pollution, which causes thousands of early deaths in London every year, is a scandal.”

London takes just one week to breach annual air pollution limits 

Parts of the capital have already breached EU hourly limits for nitrogen dioxide pollution which causes thousands of premature deaths each year

London has already breached annual pollution limits just one week into 2016, and only weeks after the government published its plans to clean up the UK’s air.

At 7am on Friday, Putney High Street in West London breached annual limits for nitrogen dioxide (NO2), a toxic gas produced by diesel vehicles that has been linked to respiratory and heart problems.

Under EU rules, sites are only allowed to breach hourly limits of 200 micrograms of NO2 per cubic meter of air 18 times in a year, but this morning Putney broke that limit for the 19th time. Chelsea and Kensington is expected to do the same later today.

Oxford Street has almost certainly also broken the limit already, having breached the hourly level a thousand times last year, but the monitoring station has malfunctioned.

Campaigners said it was “breathtaking” the breach had come so early, though Oxford Street breached the annual limit in two days in 2015.

Nationally, a roadside near the South Wales town of Swffryd appears to be the only other place to have broken the hourly limit, though it is still far from having breached the annual limit. Other sites recording high readings so far this year include ones in Aberdeen, Belfast, Exeter, Glasgow and Stoke-on-Trent, and several other roads in London.

The UK has been in breach of EU NO2 pollution limits for five years now and last spring was ordered by the supreme court to publish an action plan on how to tackle the major health crisis, following a challenge by environmental law group ClientEarth.

The resulting government plan was published in December, but London, Birmingham, Leeds, Liverpool, Cardiff and Edinburgh and other major cities will still be in breach of NO2 limits for at least another five years, despite the new measures. Private passenger cars are exempt from the plan.

Attention on the harm caused to human health by NO2 came to the fore last year when it was revealed that VW had cheated NO2 emissions tests in the US, with the scandal affecting 1.2m diesel cars in the UK. Next week, VW UK bosses will be quizzed by MPs on the Environment, Food and Rural Affairs committee on diesel pollution and what they are doing to make cleaner cars.

Andrew Grieve, an air quality analyst at King’s College London, which measures London’s air pollution levels, said the early breach in the capital was not extraordinary looking at data from previous years.

“It’s just [that] central London, and London as a whole, have a really huge problem with NO2. Breaching so early in the year really just illustrates how big a problem it is,” he told the Guardian. He added that there were lots of similar roads to those that breached limits earlier but did not have monitors on them.

Campaigners and politicians blamed the government for the breach.

Alan Andrews, a lawyer for ClientEarth, said: “This is exactly why we are taking the government back to court [over the plan it published in December]. Its failure to deal with illegal levels of air pollution, which causes thousands of early deaths in London every year, is a scandal.”

Simon Birkett, founder and director of Clean Air in London, said: “It is breathtaking that toxic air pollution in London has breached the legal limit for a whole year within a few days.”

Labour MEP, Seb Dance, said the government should ‘put up or shut up’: “Receiving this dubious accolade has become a depressing annual event for London. NOx [which includes NO2] kills thousands of Londoners every year, but the government shows no inclination to take proper action.

“Tory ministers say the right things, but in reality they have lobbied hard against ambitious new EU air quality targets and have let car manufacturers off the hook after the VW scandal. It’s time for the UK government to put up or shut up.”

Jenny Jones, a London Assembly Green Party member, said the breach demonstrated failures by the mayor of London and national government.

A spokesman for the mayor of London’s office said: “The mayor is leading the most ambitious and comprehensive package of measures in the world to improve London’s air quality. His recent £10m bus retrofit programme has led to a sustained reduction in NO2 concentrations on Putney High Street.”

A report commissioned by mayor Boris Johnson last year found that nearly 9,500 people die prematurely each year because of the capital’s dirty air. A ultra low emissions zone is due to begin in 2020 in London to help tackle the problem.

Across the UK, particulate pollution – distinct from NO2 – is blamed by Public Health England for about 30,000 premature deaths a year.

That estimate was expected to double to 60,000 annual deaths last year to take into account the additional impact of NO2. However, the government committee working on the science concluded in December that so far it has proved too hard to separate deaths from particulates known as PM2.5s and those from NO2.

Despite the difficulty of distinguishing between the two, it said that “it would be sensible to regard NO2 as causing some of the health impact found to be associated with it in epidemiological studies.”

Beijing imposed $28 million in pollution fines last year 

Beijing’s environmental watchdog levied fines totalling about 183 million yuan ($27.76 million) for violations of pollution laws in the Chinese capital last year, the state news agency Xinhua said on Friday.

The agency did not offer a comparative full-year figure, but state media reported last year that the 100 million yuan Beijing collected in pollution fines in the first nine months of 2015 was almost twice the amount as the same period during 2014.

The ruling Communist Party has only in recent years begun to acknowledge the damage that decades of growth-at-all-costs economic development have done to China‘s skies, rivers and soil.

It is now trying to equip its environmental inspection offices with greater powers and more resources to tackle persistent polluters and local governments that protect them.

An amended air pollution law, passed by the legislature in August, grants the state new powers to punish offenders and create a legal framework to cap coal consumption, the Asian giant’s biggest source of smog.

Xinhua said the fines included 44 million yuan in nearly 2,000 cases involving air pollution, which has become a hot-button issue in the Chinese capital and other cities frequently engulfed in hazardous smog that worsens during winter.

The authorities imposed fines of 72 million yuan for 181 infringements relating to water and other areas, the news agency quoted the Beijing Municipal Environmental Protection Bureau as saying.

Beijing has put nearly 20,000 pollution sources in key industries under “strict supervision”, the bureau said without elaborating.

Beijing’s average density of PM2.5 – airborne particulate matter under 2.5 microns in diameter that can penetrate deep into the lungs – from Nov. 15 to Dec. 31 rose 75.9 percent year-on-year, despite improvement in air quality throughout 2015, Xinhua said, quoting official monitoring.

Bergen restricts driving to ease air pollution

The New Year got off to a smoggy start in Norway’s West Coast city of Bergen. It’s best known for lots of rain and wind, but the stillness of cold winter days this week set off air pollution alarms that prompted officials to restrict driving into downtown.

Only cars with license plates ending with an even number were allowed to pass the toll plazas into central Bergen on Wednesday, since its date was an even number as well (January 6). On Thursday, the 7th, odd-numbered cars would be allowed to pass, and on other odd-numbered days when restrictions were in place.

Cars containing three or more people can drive all days, but city officials were keen to dramatically reduce the number of cars on the road to cut emissions. “Residents’ health must come first,” Julie Andersland, the city government leader in charge of climate and environmental issues, stated in a press release. “High levels of air pollution for several days in a row are dangerous for both adults and children. We’re not taking any chances with people’s health.”

Bergen is a city surrounded by hills, and emissions can easily get trapped in the city basin when there’s no wind or breeze. There were other exceptions to the driving restrictions: All electric and hybrid cars were allowed on the road as were motorists heading for medical appointments, drivers with handicapped authorization and those driving cars used for work were also allowed into town, even if they had odd-numbered plates on the even-numbered day.

All other drivers of private cars faced fines of up to NOK 1,500 if caught violating the restrictions, which are eased between 10pm and 6am.

Scientists develop diesel that emits far less CO2

Researchers have discovered a new approach to the production of fuels. Their new method can be used to produce much cleaner diesel. It can quickly be scaled up for industrial use. In five to 10 years, we may see the first cars driven by this new clean diesel.

Researchers from KU Leuven and Utrecht University have discovered a new approach to the production of fuels. Their new method can be used to produce much cleaner diesel. It can quickly be scaled up for industrial use. In 5 to 10 years, we may see the first cars driven by this new clean diesel.

The production of fuel involves the use of catalysts. These substances trigger the chemical reactions that convert raw material into fuel. In the case of diesel, small catalyst granules are added to the raw material to sufficiently change the molecules of the raw material to produce usable fuel.

Catalysts can have one or more chemical functions. The catalyst that was used for this particular study has two functions, represented by two different materials: a metal (platinum) and a solid-state acid. During the production process for diesel, the molecules bounce to and fro between the metal and the acid. Each time a molecule comes into contact with one of the materials, it changes a little bit. At the end of the process, the molecules are ready to be used for diesel fuel.

The assumption has always been that the metal and the solid-state acid in the catalyst should be as close together as possible. That would speed up the production process by helping the molecules bounce to and fro more quickly. Professor Johan Martens (KU Leuven) and Professor Krijn de Jong (Utrecht University) have now discovered that this assumption is incorrect. If the functions within a catalyst are nanometers apart, the process yields better molecules for cleaner fuel.

“Our results are the exact opposite of what we had expected. At first, we thought that the samples had been switched or that something was wrong with our analysis,” says Professor Martens. “We repeated the experiments three times, only to arrive at the same conclusion: the current theory is wrong. There has to be a minimum distance between the functions within a catalyst. This goes against what the industry has been doing for the past 50 years.”

The new method can optimize quite a few molecules in diesel. Cars that are driven by this clean diesel would emit far fewer particulates and CO2. The researchers believe that their method can be scaled up for industrial use with relative ease, so the new diesel could be used in cars in 5 to 10 years.

The new technique can be applied to petroleum-based fuels, but also to renewable carbon from biomass.

Pollution hotspots get ‘clean bus’ cash 

Eighteen “pollution hotspots” in England have been awarded funds to cut bus emissions, as part of efforts to meet EU targets on nitrogen dioxide.

The government has been taken to court over its failure to meet NO2 limits and has spent £20m since 2011 trying to make old polluting buses more green.

The 2015 award will split £7m between 18 areas, to upgrade 439 buses with technology to reduce exhaust emissions.

Funding was prioritised for the most polluted towns and cities.

The 18 councils and transport authorities that will share the Clean Bus Technology Fund 2015 are in Birmingham, London, Leicester, Liverpool, Sheffield, Leeds and West Yorkshire, Bristol, Brighton, Gateshead, Sunderland, Manchester, Lancashire, Norfolk, York, Harrogate, Broxbourne and Rossendale.

Fifty buses will be upgraded in London, 38 in Rossendale, 35 in Bristol and Brighton and 32 in Leeds.

The UK is failing to meet EU targets on NO2 and the government says targeting buses – which have high mileage and long “operational lives” – can help.

Among the pollution hotspots is Bristol – European Green Capital 2015 – whose mayor said the city had a “huge responsibility” to build on the momentum of UN climate talks in Paris.

He said the money would “clean up our dirtiest buses on the busiest routes”.

The buses will be fitted with “selective catalytic reduction” technology to treat exhaust gas. The government has already spent £20m on retrofit schemes since 2011, having struggled to meet EU targets on NO2 emissions, of which diesel vehicles are a key source.

In April, the Supreme Court ruled the government must put together new air quality plans by December 31 2015, after a case brought by environmental lawyers.

It revealed plans for new “clean air zones” in five cities by 2020 – which would see older polluting buses charged to enter them.

Delhi embraces car restrictions on key working day 

New restrictions on private cars, which are being enforced to tackle hazardous pollution levels in Delhi, faced their first serious test on Monday as residents headed back to work following the New Year weekend.

The scheme was launched on Friday and authorities in the Indian capital said that most drivers had complied with the rules, which require private cars with even- and odd-number plates to take to the roads on alternate days until 15 January.

There were fears many would flout the rules on the scheme’s first full working day.

But the city’s usually clogged roads saw less traffic than normal, police said, suggesting motorists with odd-number plates had sought alternative ways of getting around.

“There were doubts about what would happen when all the offices opened,” said Delhi Transport Minister Gopal Rai. “We are glad that people are following the rules.”

One way of getting people on board was through a full-page advertisement in Monday’s newspapers which compared the lungs of a 52-year-old Delhi citizen with those of a resident of a similar age from Himachal Pradesh, a mountainous state in northern India.

“DELHI HAS NOW DECLARED A WAR ON AIR POLLUTION. ON WHICH SIDE ARE YOU?” it asked readers.

Bad air

The car limiting plan is in place between 08:00 and 20:00 daily except on Sundays and the city government has put an additional 3,000 buses into service to handle an increased load.

The city’s Metro has also had to deal with a rise in passengers but on Monday, Mangu Singh, the managing director of Delhi Metro Rail Corporation, said the network was operating smoothly.

Taxi operators, which like motorcycles and women drivers, are exempt from the scheme, appeared to witness increased business.

“It’s encouraging that people have worked with the government on this. This is most important because it affects our health and our children,” said retired engineer RC Taneja, who owns both an odd- and even-plated car but chose to take the Metro for an appointment on Monday morning.

Some residents have even called for the scheme to be made permanent.

Those caught violating the rules face a fine of 2,000 rupees ($30), although many were let off with a verbal warning on Friday and Saturday.

The Press Trust of India said 1,231 people had been fined on Monday.

But what impact has it had on the city’s air quality, which the World Health Organization (WHO) says is the world’s dirtiest and a Delhi-based environmental group says is responsible for up to 30,000 deaths each year?

A visible layer of smog hovered over the city on Monday and overall pollution levels continued to be deemed “hazardous” on the US embassy’s air quality index. It advised the elderly and children to stay indoors and for everyone to avoid physical activity outdoors.

Meanwhile, PM 2.5, the small particles in the air considered dangerous for lungs and the heart, stood at 403.6 micrograms per cubic metre in the Indian capital as of 14:00 – while the safe limit defined by the WHO in 25.

What are PM 2.5 particles?

  • Particulate matter, or PM, 2.5 is a type of pollution involving fine particles less than 2.5 microns (0.0025mm) in diameter
  • A second type, PM 10, is of coarser particles with a diameter of up to 10 microns
  • Some occur naturally – e.g. from dust storms and forest fires, others from human industrial processes
  • They often consist of fragments that are small enough to reach the lungs or, in the smallest cases, to cross into the bloodstream as well
  • A build-up of PM2.5 in the lungs has been associated with causing respiratory illnesses and lung damage

As well as vehicles, experts say the burning of crops and dust from construction also heavily affect Delhi’s toxic air.

In an editorial on Monday, the Business Standard newspaper applauded the Delhi government, led by Chief Minister Arvind Kejriwal, who carpooled to work on Monday with colleagues, for “making a sincere effort in curbing vehicular pollution”.

But it added that more needed to be done, including encouraging people to buy and use battery-operated motorcycles given that “over a third of Delhi’s pollution is caused by emissions from two-wheelers”.

It also called for expanding public transport networks and upgrading them so “that people can use them with comfort in preference to their private vehicles”.

Some residents agreed.

Abheyraj Singh, 25, a smart-phone app designer, said buses “move super slow, making travelling a pain” and that “my nearest Metro station is 3-4km away, making it really hard for me to use”. He added: “I really want to use public transport and I feel everyone should, but only if it were more connected.”

Beijing air quality improved in 2015 despite pollution alerts, authorities say 

Environmental authorities in Beijing say the Chinese capital’s air quality in 2015 was better than the year before despite the city’s first two red alerts for pollution late in the year.

China has been setting national and local targets to reduce its notorious air pollution as citizens have become increasingly aware of the health dangers. Beijing’s municipal government has been replacing coal-fired boilers with natural gas-powered facilities, forcing older, more polluting vehicles off the road, and closing or moving factories that are heavy polluters.

The city’s average concentration of PM2.5 — small, inhalable particles that can penetrate deep into the lungs and are considered a reliable gauge of air quality — was 81 micrograms per cubic metre in 2015. That was a drop of 6% from 2014, and 10% lower than 2013, when Beijing started publishing data on PM2.5.

The “number of days of most serious PM2.5 pollution is falling each year,” Beijing’s municipal environmental protection bureau said Monday.

It was, however, still more than twice China’s own standard of 35 micrograms per cubic metre, and seven times higher than an annual mean of ten that the World Health Organisation gives as its guideline for safe air.

Other pollutants also fell, including sulfur dioxide by 38% and nitrogen dioxide by 12%. The environmental protection bureau attributed the lowering of sulfur dioxide to the phasing out of coal-fired heating systems.

Beijing’s air gets especially bad in the winter, when the burning of coal in northern China increases and weather patterns add to the smog.

Beijing issued its first two red alerts in December under a four-tier warning system that has been in place for two years. The city had earlier experienced more hazardous levels of pollution and come in for criticism for not issuing a red alert sooner, but authorities said at least three consecutive days of smog at particular levels on the city’s air quality index must be forecast before issuing the highest alert.

The red alerts meant half the city’s vehicles were ordered off the roads on a given day, factory production was restricted and schools were closed.

Beijing sits in one of China’s most heavily polluted regions. Its main sources of pollution are vehicles, coal-burning, industry and dust from construction sites.

The capital aims to eliminate coal use in its six downtown districts and close all coal-fired boilers throughout the city by 2020.
