Nearly All New Diesel Cars Exceed Official Pollution Limits (theguardian.com)
An anonymous reader writes: The Guardian, citing a comprehensive set of data, reports that 97% of all modern diesel cars emit more toxic nitrogen oxide (NOx) pollution on the road than the official limit. A quarter of this voluminous number emits at least six times more than the limit. From the report, "Surprisingly, the tiny number of models that did not exceed the standard were mostly Volkswagens, the carmaker whose cheating of diesel emissions tests 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. The new data, from testing industry leader Emissions Analytics (EA), follows the publication this week by the Department for Transport of emissions results for 37 vehicles, all of which emitted more NOx on the road than the official limit. But the new data covers more than 250 vehicles in more stringently standardised road conditions. EA found that just one of 201 Euro 5 diesels, the EU standard from 2009, did not exceed the limit, while only seven of 62 Euro 6 diesels, the stricter standard since 2014, did so. Diesel cars must meet an official EU limit for NOx but are only tested in a laboratory under fixed conditions. All vehicles sold pass this regulation but, when taken out on to real roads, almost all emit far more pollution. There is no suggestion that any of the cars tested broke the law on emissions limits or used any cheat devices. Mayoral candidates in London, the city with the worst air quality in Britain, have seized on the DfT data to call for tighter controls on polluting traffic -- including a ban on diesel cars."Caroline Pidgeon, the Lib Dem mayoral candidate, said: "The figures are exactly the reason why we need to speed up the introduction of the ultra-low emission zone so that it starts in 2018. Ultimately we will need to ban diesel vehicles from much of London and we need a mayor prepared to take these tough decisions and work with people to make these changes happen."
Limits must be defined in terms of the condition of the test. If testing is done outside those defined conditions, the limits are hard to apply and enforce. Seems like the regulators need to re-define the limits and testing method.
I am shocked, SHOCKED, that clean diesel is just another totally meaningless advertising slogan!
The cars only have to pass a laboratory test. If that test bears no resemblance to the real world (which the EU one doesn't) then thats the fault of the people who devised it.
The main problem with emissions is if you want good fuel economy and hence lower CO2 per km then you need a high burn temp. The trouble with that is a high burn temp gives high NOx. Take your pick.
The only serious solution to NOx is a urea system such as adblue as used in trucks but thats more equipment, more complexity and more expense.
Before this fact was just used for public shaming of one german manufacturer... Believe me, they did this purposefully to force Germany to agree to secret ISDS courts (aka "this wouldnt happen with ISDS courts, look how badly VW is doing").
Paranoid conspiracy in four posts!
Not quite a record, but an achievement nonetheless. You should get some mod points.
Faster! Faster! Faster would be better!
What it actually means is slightly less dirty diesel.
Even if new diesel cars did pass this test they'd still start blowing black soot and other crap after a number of years have passed and the car has reached owner number 3 who isn't bothering to do anything other than basic maintainance to keep it on the road until it falls apart.
The Internet is full of enlightening Europeans heaping scorn upon lowly Americans for not using their awesome "clean diesel" technology. Silly Americans still driving non-diesels!
Expecting "independent" labs to actually be independent is not much better. Remember that it was a Swiss academic lab that found the original problem, because no German lab could be found that was willing to make these measurements on a German car. They all had a lot of business to lose and probably had reason to expect that the measurements would show massive problems. As soon as enough money is involved, the whole complex becomes corrupt. And, just as with the financial crisis of 2008, I predict that nobody will go behind bars for this, or at best some lowly scapegoats.
Most ACs are not even worth the keystrokes to insult them. Be generically insulted by this and ignored otherwise.
You should look up sarcasm in the English Common law library. Hopefully, you find it.

Unfortunately, yes. And that is what eventually kills a society: Too many self-centered fucks that do not care about anything except themselves.

If we avoid lab conditions, you bring in random factors. So some heavy polluting car could just get lucky and have no sharp stops and quick speed ups, which is where it happens to heavily pollute, so it passes.
We need lab conditions to ensure a fair comparison between different cars.
It is assumed that all cars vary from real life to lab conditions in roughly the same manner. That is, that a car that does best in the lab conditions will also do best in real world conditions, even if the real use pollutes far more heavily.
In addition, we assume that the lab is similar enough to real world so that we know how much we are polluting.
If either of those assumptions are false, it indicates a bad lab condition set up which needs to be fixed. But that is not the fault of the car companies, but instead the fault of the politicians and scientists that designed the lab. (Yes, it is often designed by politics, not scientists.)

Emissions controls on a big stationary power plant is much easier and much more efficient than emissions controls on cars.
Eat the rich.
Where did you go to school?
The USA Constitution says that the rights of the Federal Government are severely restricted, that is, they are listed in the USA Constitution.
The rights of the people (individuals as 1 or a group such as a State) have severely UNrestricted rights.
The Bill of Rights ONLY lists some of the unrestricted rights of the individual or states. The fact that the Bill of Rights does not address a particular right that an individual has does not mean the individual does not have that right. To the contrary, the individual, under the USA Constitution, has the vast majority of rights and these rights need not be listed for the individual to have those rights.
History shows that the USA Federal Government has continually and constantly disregarded and restricted the rights of the individual as often as the Federal Government can. And without regard to what is Constitutional, legal or illegal.
The USA Supreme Court has limited the rights of the local and state Governments in most cases that it has ruled on. The local and state Governments do not have unrestricted rights.
This is what you should have been taught in the Government Schools (I was).
The is what you should have read, the USA Constitution, in the Government Schools (I did).
This is what you should know to pass a citizenship test.
