Après celle du climat, l’industrie et ses lobbyistes s’attaquent à la science de la pollution de l’air - Observatoire des multinationales
Après le climato-scepticisme, le dieselo-scepticisme ? « L’air moderne est un petit peu trop propre pour une santé optimale » ; « on ne peut pas faire de lien entre décès prématurés et ozone » ; « [si la pollution de l’air tue,] où sont les corps ? » ; « les experts ne sont pas d’accord entre eux quant à la réalité de l’impact sanitaire des particules fines » ; « la qualité de l’air n’a jamais été aussi bonne qu’aujourd’hui »… Telles sont quelques-unes des phrases que l’on a pu récemment glaner, de divers côtés, dans les médias ou les réseaux sociaux en France, aux États-Unis et ailleurs. Alors que des voix de plus en plus nombreuses s’élèvent pour dénoncer l’impact sanitaire de la pollution de l’air, et les dizaines de milliers de décès prématurés qu’elle provoque chaque année en France et dans le monde, certains font de la résistance.

Ce « déni de la pollution de l’air » se manifeste aussi sous une autre forme, dans certaines études « scientifiques » financées par des constructeurs automobiles. Le New York Times a raconté il y a quelques jours comment une officine crée par Volkswagen avait payé des chercheurs pour faire respirer des vapeurs de diesel à un groupe de singes, dans le but de prouver leur innocuité.

The Bomb That Went Off Twice
RDX, it turned out, does not dissolve in water, quickly degrade underground, or cling to soil particles that can keep it in place and limit its spread. Instead of becoming diluted over distance — like many other pollutants — it remains concentrated, and then travels quickly.

“It’s widely used, persistent, and mobile,” said the EPA’s Craig. “It doesn’t go away.”...
It didn’t take long for the EPA to realize the military’s role as environmental offender.

The Pentagon, the agency learned, was responsible for legions of disastrously contaminated sites across the country, sites that by sheer number would soon dwarf the liabilities of any other single entity. There were the artillery testing grounds, packed with unexploded ordnance; the chemical weapons ranges; and the rocket fuel and airplane sites, saturated with solvents and fire retardants. The damage at the sites was so serious that in 1984 the EPA amended the rules of its Superfund cleanup program — the powerful 1980 law that allows federal authorities to take jurisdiction over the highest-priority contamination sites in the country and mandate their cleanup — to include military sites. Then it listed 36 of them.

The Three Students Who Discovered Dieselgate - SPIEGEL ONLINE
The biggest problem with diesel engines was not carbon emissions, as it is with gasoline engines, but nitrogen oxide (NOx). The U.S. permits much lower nitrogen oxide emissions than Europe does, but certain technologies made it possible to lower emissions to American NOx emissions standards. They, on the other hand, brought a different set of problems - more on them later. ...
The thinking was that if VW's diesel cars had to abide by such strict emissions standards in the U.S., then the company might as well make a virtue of necessity and promote its turbo diesel engines as "green."

"It's not that there was suspicion. On the contrary," says Arvind. "We were just very curious. These diesel emission technologies were quite new. And we knew they worked on paper. But they had never been tested in passenger cars under real driving conditions."

Mine de Salau : la peur de la pollution dévale du Haut-Salat à la Garonne - 25/10/2017 - ladepeche.fr
Une pollution du Salat, puis de la Garonne, c'est la crainte agitée par les opposants à la réouverture de la mine de Salau, dans le Haut-Couserans (Ariège). Ils veulent alerter l'opinion, jusqu'à Toulouse.

Les défenseurs des milieux aquatiques mobilisent autour du projet de réouverture de la mine de tungstène de Salau, dans le Haut-Couserans (Ariège). Et se tournent vers la Ville rose. «Ce qui se passe sur le Salat concerne la vallée de la Garonne. Ce qu'on met là-haut se retrouvera en bas dans dix ans ou dans vingt ans. Il faut raisonner en solidarité de versant», estime Henri Delrieu, porte-parole du Chabot, association de défense des milieux aquatiques, l'une des associations qui appellent à la mobilisation. Il y aurait, sur le site minier fermé en 1987, «un million de mètres cubes de déchets pollués ont été abandonnés à l'air libre sur le site» voici trente ans. «Dans des conditions de stockage déplorable», confie Jean-Pierre Delorme, du Comité écologique ariégeois. «Il y a aussi la question de l'eau qui a envahi les galeries, environ 2 millions de mètres cubes, chargées d'amiante et de métaux lourds, et qu'il faudra évacuer pour reprendre l'exploitation. Comment seront traitées ces eaux ? Nous n'avons aucune réponse»,

China Fossil Fuel Deadline Shifts Focus to Electric Car Race - Bloomberg
The world’s second-biggest economy, which has vowed to cap its carbon emissions by 2030 and curb worsening air pollution, is the latest to join countries such as the U.K. and France seeking to phase out vehicles using gasoline and diesel. The looming ban on combustion-engine automobiles will goad both local and global automakers to focus on introducing more zero-emission electric cars to help clean up smog-choked major cities.

“The implementation of the ban for such a big market like China can be later than 2040,” said Liu Zhijia, an assistant general manager at Chery Automobile Co., the country’s biggest passenger car exporter that unveiled a new line for upscale battery-powered and plug-in hybrid models at the Frankfurt motor show last week. “That will leave plenty of time for everyone to prepare.”

UN Shipping Climate Talks ‘Captured’ by Industry | DeSmog UK
Shipping has a carbon footprint roughly the size of Germany. Without intervention, the IMO’s own research predicts that to grow 50-250 percent by 2050.

The latest available data, published by the International Council on Clean Transportation last week, showed emissions increasing 2.4 percent between 2013 and 2015. Fuel efficiency improved for many ship classes over the period, but the gains were outweighed by increased demand.

Motorcycles and emissions: The surprising facts - LA Times
Motorcycles and scooters are, on average, about twice as fuel efficient as cars. Compact and lightweight, their internal-combustion engines do a better job of converting fuel into energy that makes the vehicle move. But extracting more energy from the fuel has a downside. It produces greater amounts of a smog-forming emission called oxides of nitrogen.

Analysis: Switch to electric vehicles would add just 10% to UK power demand | Carbon Brief
Note that EVs offer CO2 savings even under relatively CO2-heavy electricity grids including coal-fired generation. This is because EVs are more efficient than combustion-engine cars. Similarly, the CO2 associated with manufacturing EV batteries is more than offset by savings during EVs’ lifetimes.

A comprehensive literature review from the International Council on Clean Transportation (ICCT) says EVs offer CO2 savings of 40-50% compared to average combustion engine vehicles. This includes full lifecycle emissions including manufacture, use and electricity generation, based on an EU average grid mix. This means EVs could cut global emissions by 1.5 billion tonnes of CO2 per year in 2050, a second ICCT study says.

The Toxins That Threaten Our Brains - The Atlantic
Dr. Linda Birnbaum is the director of the National Institute of Environmental Health Sciences and the National Toxicology Program in North Carolina’s Research Triangle. Birnbaum oversees federal funding for research to discover how the environment influences health and disease, including Tox21.

“If you want to do the full battery of current tests that we have on a chemical, you’re looking at least five years and about $5 million,” Birnbaum told me. “We’re not going to be able to do that on large numbers of chemicals.” The robot is being trained to scan thousands of chemicals at a time and recognize threats inexpensively and quickly—before people get sick. It’s also using alternative testing models—looking at not just isolated cells, but also simple organisms like the roundworm C. elegans or zebrafish—to answer certain basic questions.

La position du CéDpa confirmée par l’Autorité de Contrôle des Nuisances Aériennes - ACIPA NDL
L’ACNUSA consacre en effet un long développement aux progrès réalisés par l’industrie aéronautique en matière de bruit : « Depuis la fin des années 1990, le bruit des avions a été divisé par deux. Et on estime que l’empreinte sonore de chaque nouvelle génération d’appareils est inférieure d’au moins 15 % à celle qu’elle remplace. En outre, presque partout, en dépit de l’augmentation du trafic, les territoires couverts par les PGS pourraient diminuer. »

Elle conclut : « La première leçon à tirer est que la situation des riverains s’améliore et continuera de s’améliorer même si le trafic doit encore augmenter. (…) Dépenser plusieurs milliards pour déplacer un aéroport (ou ses pistes !) dans le seul but de mettre fin à un niveau de nuisance qui n’existera plus dans vingt ou trente ans ne peut pas être regardé comme raisonnable. » (page 33). Si la phrase se réfère explicitement au projet de déplacement des pistes à Orly, projet jugé illusoire par l’Autorité, on ne peut évidemment s’empêcher de penser aussi à Notre-Dame-des-Landes ...

N’est-ce pas ce que nous avons dit et écrit depuis plusieurs années ?

Le deuxième point intéressant concerne la révision des Plans de Gêne Sonore, en général. Précisément parce que la réalité du bruit se modifie, l’ACNUSA demande « que soit examinée au moins tous les deux ans la pertinence des prévisions (trafic, procédures de navigation aérienne, infrastructures...) ayant servi à l’établissement du PGS. »

Brain pollution: Evidence builds that dirty air causes Alzheimer’s, dementia | Science | AAAS
an 11-year epidemiological study to be published next week in Translational Psychiatry, USC researchers will report that living in places with PM2.5 exposures higher than the Environmental Protection Agency’s (EPA’s) standard of 12 µg/m3 nearly doubled dementia risk in older women. If the finding holds up in the general population, air pollution could account for roughly 21% of dementia cases worldwide, says the study’s senior author, epidemiologist Jiu-Chiuan Chen of the Keck School of Medicine at USC.

Deepening the concerns, this month researchers at the University of Toronto in Canada reported in The Lancet that among 6.6 million people in the province of Ontario, those living within 50 meters of a major road—where levels of fine pollutants are often 10 times higher than just 150 meters away—were 12% more likely to develop dementia than people living more than 200 meters away.

Lobbies : l'insoutenable complaisance des élus -- Jacques GUÉRIN
Le 16 avril 2015, Michel Aubier, pneumologue à l’hôpital Bichat, intervient devant les sénateurs de la commission d’enquête « sur le coût économique et financier de la pollution de l’air ». Il déclare alors sous serment n’avoir « aucun lien d’intérêts avec les acteurs économiques ». Mais un peu moins d’un an plus tard, Libération et Le Canard Enchaîné révèlent que le pneumologue est rémunéré par Total comme médecin-conseil auprès des dirigeants du groupe. Convoqué par la commission sénatoriale pour s’expliquer, le médecin reconnaît alors toucher 5 000 euros par mois du groupe pétrolier. L’affaire est d’autant plus gênante que dans les médias ou devant les sénateurs, ce médecin a plutôt eu tendance, selon Le Monde, à minimiser les effets sur la santé de la pollution aux particules fines...

Revealed: nearly all new diesel cars exceed official pollution limits | Business | The Guardian
Ninety-seven percent of all modern diesel cars emit more toxic nitrogen oxide (NOx) pollution on the road than the official limit, according to the most comprehensive set of data yet published, with a quarter producing at least six times more than the limit.

Surprisingly, the tiny number of models that did not exceed the standard were mostly Volkswagens, the carmaker whose cheating of diesel emissions tests which emerged last year sparked the scandal. Experts said the new results show that clean diesel cars can be made but that virtually all manufacturers have failed to do so.

EU Industry chief sees 'fast' phase-out of diesel post-VW scandal | Reuters
EU lawmakers voted 585 to 77 in favor of the draft bill, which would bolster EU oversight and allow Brussels to fine car makers up to 30,000 euros ($31,923.00) per vehicle.

The new measures will eventually take diesel cars off the roads, European Commissioner Elzbieta Bienkowska said.

"Diesel will not disappear from one day to another," Bienkowska told EU lawmakers on Tuesday. "But after this year of work ... I am quite sure they will disappear much faster than we can imagine."

Under the draft law, car makers would no longer directly pay testing agency - in a bid to break their cozy relationships. EU nations now have to fund car exhaust testing centers - although they may levy fees from car makers to do so.

Quand baisser la limite permet de rouler plus vite - La Presse+
En janvier 2014, la capitale française a réduit de 80 à 70 km/h la limite de vitesse sur les voies rapides la ceinturant. Alors que de nombreux automobilistes craignaient de voir leurs allées et venues traîner en longueur, c’est précisément le contraire qui s’est produit. Le matin, la vitesse moyenne observée sur le « Périph’ » est passée de 32,6 km/h en 2013 à 38,4 km/h l’an dernier, une amélioration de 18 %. À l’heure du retour à la maison, les voitures roulent en moyenne 12 % plus vite.

MATER L’EFFET ACCORDÉON

Comment expliquer ces résultats ? En baissant sa limite de vitesse, Paris dit avoir réduit l’« effet accordéon ». Ce phénomène survient quand les voitures freinent et accélèrent à répétition dans un bouchon de circulation.

Diesel : Renault soupçonné d’enfumage à grande échelle - Libération
En cause, le système de dépollution par recirculation des gaz d’échappement (EGR) low-cost qui équipe la plupart des diesels Renault. Ce dernier semble bien moins performant que celui du rival PSA Peugeot-Citroën, qui a misé, lui, sur un système catalytique plus cher mais apparemment plus efficace. De plus, Renault bride son système de dépollution pour ne pas affecter les performances du moteur de ses véhicules. La marque joue sur l’ambiguïté d’un règlement européen de 2007 qui interdit l’utilisation de logiciels bridant l’efficacité d’un système de dépollution, sauf en cas de «protection du moteur […] et pour le fonctionnement en toute sécurité du véhicule». «Ce système antipollution est censé fonctionner dans une plage de température d’admission d’air de 17 à 35 degrés. Mais, au démarrage, la température est souvent inférieure et dès qu’il y a du trafic elle est systématiquement supérieure. Résultat, la plupart du temps, dès que la voiture roule, il n’est pas opérationnel», pointe Lepitre de FNE.

Il y aurait donc «tromperie» manifeste du consommateur sur le fonctionnement du système et sur la réalité des émissions de NOx. Toute l’ambiguïté de l’affaire porte alors sur l’efficacité du «contrôle» au moment de l’homologation des véhicules, qui semble lui aussi visé par l’instruction des juges du parquet de Paris. En France, c’est l’Utac, un organisme privé, qui est chargé par les autorités de procéder aux essais d’homologation dans ses centres de Mortefontaine (Oise) et Montlhéry (Essonne). Or, la plupart des véhicules testés passent ce contrôle comme une lettre à la poste car les constructeurs maîtrisent parfaitement le processus de mesure d’émissions polluantes : «Le problème, c’est que le banc d’essai fonctionne avec une température moyenne d’admission de l’air de 23 degrés qui est pile-poil dans la fourchette où le système de dépollution fonctionne parfaitement, poursuit Lepitre. Cela arrange les constructeurs. Il faudrait pouvoir tester les diesels entre - 7 °C et + 45 °C et là, l’homologation Euro 6 serait bien plus difficile à obtenir.»

Eric Vidalenc » Blog Archive » La pollution locale, ou la paille et la poutre
Mais les enjeux des pollutions locales sont …locaux. Et entre un niveau global d’émissions (à l’échelle française par exemple) et des problèmes locaux (pic de pollution quotidien ou hebdomadaire), le lien est loin d’être évident. Ainsi, les émissions globales décroissent mais les concentrations stagnent comme ces suivis annuels d’AirParif le montrent… et l’on ne sait pas grand-chose des expositions réelles des populations (selon les lieux, temps et modes de vie notamment).

Les sources d’émissions sont multiples mais la diésélisation du parc de véhicules et le maintien de chauffage bois, des feux de cheminées dans des foyers ouverts plus précisément, sont responsables de la moitié des émissions. Ensuite, agriculture et industrie complètent le tableau général. Mais à proximité des axes de circulation ou dans certaines vallées, les émissions liées aux trafics routiers ou au chauffage sont bien entendu plus importantes.

Why electric cars are only as clean as their power supply | Environment | The Guardian
the Union of Concerned Scientists – which works to raise awareness of climate change – believes that despite a fossil-fuel-dependent grid, electric cars are, on balance, better for the environment.

“There are no areas of the country where electric vehicles have higher global warming emissions than the average new gasoline vehicle,” the campaign group claims in its paper, State of Charge, which calculates the emissions equivalent of an electric vehicle using the makeup of the local energy supply. Using UCS’s formula, a Tesla Model X charging in the Los Altos Whole Foods garage achieves a fuel efficiency equivalent to 81 miles per gallon – far higher than a gas-powered car.

Yet not all scientists agree with that approach. “All of the action is in the hourly,” says Graff Zivin. It’s not only the region that an electric vehicle plugs into that matters. The hour of the day is equally critical. “The cheapest power is not the greenest power.”

In California, the cheapest power is produced at night, mostly from natural gas, hydroelectric dams and nuclear. Night is when many people will charge their electric cars. However, the greenest power gets generated during the day

an EU pledge to “organise and carry out” emissions tests has been deleted from a draft regulation, which will be discussed by EU ministers this week in Brussels.

Julia Poliscanova, a spokeswoman for the green campaign group, Transport and Environment, said: “There is a Mexican standoff going on, with governments afraid to act against their own fraudulent carmakers for fear it will put their domestic industry at a competitive disadvantage.

“This scandalous stalemate results from national governments prioritising the interests of domestic carmakers above citizens’ need to breathe clean air. National vehicle regulators in Europe have been captured by the car industry.”

Particulate air pollution and impaired lung function - F1000Research
Air pollution is associated with millions of premature deaths worldwide1, 25% of which are estimated to be respiratory in nature2, and is the world’s largest environmental health risk3. In an attempt to mitigate ambient exposure to air pollution, the Environmental Protection Agency (EPA) currently regulates six criteria air pollutants under the Clean Air Act4. Of the regulated pollutants, particulate matter (PM) has been extensively studied and associated with a myriad of adverse health outcomes, including an adverse impact on lung function in both children and adults5–7. PM is a complex mixture of liquid droplets and extremely small particles composed of organic and inorganic compounds7. PM less than 10 μg in aerodynamic diameter, designated by PM10, can penetrate conducting airways; PM2.5 (PM less than 2.5 μg in aerodynamic diameter) is composed of fine particles and can penetrate into the gas-exchanging regions of the lung6. Sources of ambient PM include construction sites, smokestacks, fires, power plants, and automobiles; the main sources of indoor PM include ambient PM, tobacco smoke, cooking, and heating appliances. PM causes lung inflammation and mucous secretion by acting on airway epithelial cells and alveolar macrophages and may lead to airway remodeling8.

Exhaust-ed Cyclists — Fireseeds North Infrastructure
Studies have concluded that cyclists are at a greater risk of illness due to the higher intake of pollutants from a higher breathing rate during exercise compared to a pedestrian walking [3,4]. Particles travel deeper into the lungs and have more severe health affects [2]. Researchers have also linked cancer [5] and heart risk [6] to the air pollution levels cyclists encounter and that diesel fumes are more harmful to cyclists than regular gasoline [4].
Separation Matters

A key factor in determining whether a right- or left-sided tailpipe has a greater impact on cyclists is whether or not the distance from a tailpipe to the cyclist is important and if there is a safe distance. In research investigating whether drivers or cyclists are more exposed to air pollutants, the results are conflicted. Some studies show that cyclists are more exposed than drivers [3], while others state that cyclists are less exposed [7,8]. Studies that suggested that cyclists are less exposed highlighted cyclists' ability to by-pass congestion and the partial separation of cyclists from traffic [3,9]. Since these studies suggest that a decrease in exposure for cyclists is due to physical separation from traffic, what does this mean for all the roads without separated cycling infrastructure and where cyclists may be stuck in grid-lock with vehicles? Studies also found that pedestrians were at a lower risk of exposure to pollutants than drivers and cyclists [6]. This supports the use of separated bike facilities such as bike lanes or multi-use paths in order for cyclists to avoid traffic and pollutants.

About | Clean Air in London
Air pollution in our biggest cities is much worse than most of us have realised. It averages well over twice World Health Organisation (WHO) guidelines and legal limits near many of London’s busiest roads. Mayor Johnson has estimated some 4,300 premature deaths in London in 2008 were attributable to long-term exposure to dangerous airborne particles alone.

Clean Air in London’s Mission is to achieve urgently and sustainably full compliance with WHO guidelines for air quality throughout London and elsewhere. It works closely with other campaign groups and a wider network of supporters and volunteers to identify and build understanding of the most important issues and encourage decisive action on them.

Clean Air in London’s immediate priority is to see that air quality laws are enforced rigorously in London in 2014 (and thereafter).

researchers set up a monitoring station on Oxford Street and found a peak level of nitrogen dioxide of 463 micrograms per cubic metre of air (mcg/m3), over 11 times higher than the European Union’s limit of 40mcg/m3.

On average, including nights when the traffic is lighter and emissions level drop, the level of nitrogen dioxide is 135mcg/m3 — still four times the limit.“It’s a quirk of modern diesels that they produce more NO2 then in the past. This is because they have been designed to use NO2 to burn off particulates but, in the stop-start conditions found in congested streets, the systems are inefficient and produce far too much NO2.

“This is compounded by the high buildings on either side, which concentrate it to dangerously high levels.”

Richard Dickinson, chief executive of New West End Company which represents traders in Oxford Street, Regent Street and Bond Street, said a reduction in traffic was essential.

London bike couriers set to map the capital's pollution | road.cc
A team of 50 cycle couriers from London same-day courier service Gophr are set to be equipped with carbon monoxide monitors to map the capital's pollution.

The project goal is to create "the world's most advanced air pollution map," and has been masterminded by former Labour minister Paul Drayson's firm Drayson Technologies, which works towards connecting the world via the 'internet of things.

Drayson Technologies has equipped Gophr cycle couriers with 50 of their carbon monoxide sensors which they call CleanSpace Tags.

These tags will collect data from the trips each rider takes every day and will compile it to make a real-time map of the air pollution levels around the city.

The cyclists are expected to cover around 17,000 per month, and the data collection won't be relying on patchy and unreliable mobile phone GPS connections. Each CleanSpace Tagged ride will have its height and real-time location data monitored using long range trackers developed by Inmarsat - a satellite communications provider - to give precise context to the air pollution data collected.

EU caves in to auto industry pressure for weak emissions limits | Environment | The Guardian
The European Automobile Manufacturers Association (ACEA) welcomed the decision by a Brussels technical committee as a “robust but realistic package that will address the key environmental issues under a two-step approach”.

The industry argues that the exemptions – known as conformity factors – were needed to prevent earnings shortfalls, and to reflect testing uncertainties. But MEPs and campaigners were shocked at what they saw as a cave-in by the European commission.

CDU Gets Donation From BMW Owners During CO2 Talks - SPIEGEL ONLINE
After months of forceful lobbying from Germany, the ministers from the 28 EU member states agreed to reopen a deal sealed in June. German carmakers Daimler and BMW produce heavier vehicles that consume more fuel than vehicles made by firms such as Italy's Fiat. That means they would find it harder to meet a proposed EU cap on carbon emissions of 95 grams per kilometer for all new cars from 2020, analysts say.

Revealed: nearly all new diesel cars exceed official pollution limits | Business | The Guardian
Ninety-seven percent of all modern diesel cars emit more toxic nitrogen oxide (NOx) pollution on the road than the official limit, according to the most comprehensive set of data yet published, with a quarter producing at least six times more than the limit.

Surprisingly, the tiny number of models that did not exceed the standard were mostly Volkswagens, the carmaker whose cheating of diesel emissions tests which emerged last year sparked the scandal. Experts said the new results show that clean diesel cars can be made but that virtually all manufacturers have failed to do so.

Pollution atmosphérique : Michel Aubier face à ses mensonges
Cinquante mille à soixante mille euros par an : c’est ce qu’a confessé avoir touché du pétrolier Total, depuis la fin des années 1990, le pneumologue Michel Aubier, chef de service à l’hôpital Bichat, à Paris. Le médecin était entendu à huis clos, jeudi 17 mars au matin, par la commission d’enquête du Sénat sur le coût de la pollution atmosphérique, dans une ambiance assez lourde. Et pour cause. Voilà près d’un an, le 16 avril 2015, dans le cadre de ses travaux, cette même commission avait auditionné en tant qu’expert M. Aubier, qui avait déclaré en préambule de son intervention : « Je n’ai aucun lien d’intérêt avec les acteurs économiques. » Une déclaration sous serment démentie par Libération et Le Canard enchaîné qui ont révélé, mercredi, que le professeur exerçait depuis 1997 les fonctions de médecin-conseil pour Total, chargé de conseiller les cadres dirigeants du groupe en cas de problèmes de santé.

Ces derniers ont obtenu le doublement des normes d'émission des oxydes d'azote, les NOx, en contrepartie de nouveaux tests plus rigoureux qui incluraient des contrôles sur route. Le poids des lobbys a malheureusement pleinement pesé sur cette décision. On observe exactement la même chose avec les chimistes et leurs pesticides.

Volkswagen faces billions in penalties as U.S. sues for environment violations | Business | Reuters
"The United States will pursue all appropriate remedies against Volkswagen to redress the violations of our nation's clean air laws," said Assistant Attorney General John Cruden, head of the departments environment and natural resources division.

The Justice Department lawsuit, filed on behalf of the Environmental Protection Agency, accuses Volkswagen of four counts of violating the U.S. Clean Air Act, including tampering with the emissions control system and failing to report violations.

The lawsuit is being filed in the Eastern District of Michigan and then transferred to Northern California, where class-action lawsuits against Volkswagen are pending.

"We're alleging that they knew what they were doing, they intentionally violated the law and that the consequences were significant to health," the senior Justice Department official said.

Journal of Exposure Science and Environmental Epidemiology - The Fort Collins Commuter Study: Impact of route type and transport mode on personal exposure to multiple air pollutants
Previous studies comparing particulate exposures between drivers and cyclists present mixed results.27, 28, 29, 30, 31, 32 Boogaard et al.33 and Panis et al.,28 for example, compared driving and cycling exposures to PNC and PM2.5 across multiple cities and found that the direction and magnitude of relative differences varied from city to city. Other studies, however, observed increased mean exposure to particulate pollutants when driving (e.g., BC (49%34), PM2.5 (12%35 and 17%34), PNC (6%35 and 36%34) and elemental carbon (41% summer and 44% winter30)) in drivers relative to cyclists on comparable routes. Local traffic patterns, fleet composition, vehicle operation, topography, and proximity to source (i.e., the tailpipe) all likely contribute to the relative differences in exposure between cyclists and drivers. An increase in mean CO exposure when driving is consistent with several previous studies.32, 35 The observed increase in mean CO exposure when driving (15% to 20% greater than cycling) is similar to Kaur et al.35 (15%) but lower than de Nazelle et al.32 (75% geometric mean). Additional studies comparing cycling and driving exposures to gaseous air pollutants have found driver’s exposure is elevated by 60% to 75%.13, 29

Europe's love affair with diesel cars has been a disaster - Vox
In other words, 20 years of increasingly stringent air pollution regulations had done basically nothing to reduce pollution. "That was the most surprising part," Williams says.

By that point, the damage had been done. Today, Paris occasionally jousts with Beijing for the title of world's most polluted city. London is grappling with unsafe levels of nitrogen dioxide. Germany, Austria, and Ireland have NOx pollution well above the legal limits, with vehicles accounting for nearly half that output.

The health toll is considerable. One recent study estimated that diesel pollution from cars, buses, and trucks in Britain caused 9,400 premature deaths in 2010 alone. It's difficult to pinpoint what fraction of those deaths might have been avoided if emission rules had been enforced all along, but that gives some sense of the stakes here.

Energy Outlook: What the Congressional Hearing on VW Missed
Mr. Horn's response to a question about the timeline for attempting to fix the company's non-complying diesel cars from model years 2009-2015.

He explained that the affected models included three generations of engine and emissions treatment technology. The oldest, which he described as "Gen-1" would be the hardest to fix and was clearly not amenable to merely updating the engine management software to remove the "defeat device" code. However, he also indicated that the newest generation might be fixed in exactly that way. That's because they already incorporate the Selective Catalytic Reduction and urea technology used in bigger, more expensive models.

the German economic model. It has been over-reliant on the car industry, just as the car industry has been over-reliant on diesel technology....
To gauge the wider economic impact, one needs a sense of the size of the industry. It is much larger than official statistics suggest because they do not account for the interdependencies across industries. The car industry is by far the largest single buyer of goods and services from other sectors. According to a study published in 2008 by the University of Mannheim, the car industry accounted for 7.7 per cent of gross value-added for the whole of Germany in 2004 — the highest percentage of any country in the world.

Wide range of cars emit more pollution in realistic driving tests, data shows | Environment | The Guardian
New diesel cars from Renault, Nissan, Hyundai, Citroen, Fiat, Volvo and other manufacturers have all been found to emit substantially higher levels of pollution when tested in more realistic driving conditions, according to new data seen by the Guardian.

Research compiled by Adac, Europe’s largest motoring organisation, shows that some of the diesel cars it examined released over 10 times more NOx than revealed by existing EU tests, using an alternative standard due to be introduced later this decade...

“Gaming and optimising the test is ubiquitous across the industry,” said Greg Archer, an emissions expert at Transport & Environment.

Not just emissions: manufacturers' dirty tricks fake everything about cars / Boing Boing
Worst of all, though, is that once this charade has produced a claim as to the car’s efficiency, no one checks whether it is true or not. In America, too, carmakers are responsible for their own tests. But there the EPA goes on to acquire vehicles at random for testing at a later date, to see if the cars on sale to the public live up to the claims. If the numbers do not match up substantial fines can follow. In 2014 Hyundai-Kia was fined $300m for misstating fuel-economy figures. Europe has no such system for punishing those who transgress. As a result more than half Europe’s claimed gains in efficiency since 2008 have been “purely theoretical”, says T&E. And the industry as a whole has developed a gaming attitude to tests and regulations that it should take seriously. As Drew Kodjak of the ICCT observes, VW’s activities in America are part of a pattern of behaviour that the “European system created”.

All choked up: did Britain's dirty air make me dangerously ill? | Environment | The Guardian
In the 1990s, climate change was rising fast up the international agenda and, following the 1997 signing of the Kyoto protocol, rich countries were legally obliged to reduce emissions by an average of 8% over 15 years. But while Japan, China and the US chose to back research into low-emission hybrid, petrol and electric vehicles, Europe prioritised a mass public switch to diesel, announcing that it not only gave 15-20% better mileage to the gallon, but emitted around 13-17% less carbon dioxide, the main climate-changing gas. The motor industry, governments and the green lobby reasoned that it would be one of the cheapest and easiest ways to tackle climate change.

By any measure, the transformation of the European car fleet from almost entirely petrol to predominantly diesel was rapid and remarkable. Britain, along with Germany, France and Italy, offered subsidies and sweeteners to persuade car makers and the public to buy diesel. Key to the change was the 1998 Acea voluntary agreement between the European commission and all European car makers, backed strongly by then EU transport commissioner Neil Kinnock and UK environment secretary John Prescott. This committed all car makers selling in Europe to reduce their average CO2 emissions for new passenger cars by 25% over 10 years.

That's a fancy way of saying it can live with or without oxygen and can make it's own parts by pulling carbon dioxide out of the air and fusing it together using energy derived from sulfur or hydrogen gas. It's also happy to use organic carbon, if it's available, including aromatics such as toluene and phenol that are widespread pollutants of soil and groundwater.
