11am Radio5 "tens of thousands of diesel cars/vans are driving around with their diesel particulate filter DPF taken out"
Garages know a way of legally removing the inside and rewelding the cover shut, so it's not detected in the MOT.
- Well there must be 10m+ diesel cars/vans so the problem is only 1-2 in a thousand.
- The MOT is changing in May.
Hmm in the London Czone let's say there are 2,000 diesels and Sadiq removes 200
So maybe there are 10 unfiltered diesels remaining which push out the same dirt as those 200.

The issue with DPF is they clog up if you only do short journeys so reducing car performance
Motorway run regenerates them
But removing them means you don't have to bother.
If you left it ..a clean up could cost £100+
If it breaks a replacement could cost £1000+

BBC DPF story
One guy on Twitter says for his VW since the fix his DPF has been getting clogged up.

Sunday Radio 5 had a prog on Diesel Particulate Filters being removed and being undetected by MOT
( it is a known problem and the gov is already rolling out a plan with the MOT rules set to change in May 2018)
It was full of Guardian-like sloppiness : Labour Party PR, emotional blackmail, and anecdotal hysteria against diesels.
(My post at the top of the page explains why DPF's get removed)

Prog opened with presenter saying
"problem that already costs 40,000 lives per year"
Next said : "40,000 lives are cut short every year"
- They contradict and are both WRONG

Labour MP Mary Cray came on repeated the 40K statement
"Villages effected as well" ..wrong to imply that diesel effects villages
.... Particulates can happen in villages, but due to agriculture.
"Lung capacity unborn babies"
... Big claim that Google provides no evidence for.

Labour Transport guy Andy MacDonald came on to beg for law changes right now about DPF's
That's strange to me cos with it's May 2018 plan the government does seem to have the issue in hand. I don't see that proper procedures could be brought in much quicker ..cos when you rush , things get screwed up.

The third Labour Party spokesman in this 45 minute segment was
when PR statement from Sadiq Khan was read out.
Then Sadiq's initiative of Air Marshalls who patrol streets asking drivers to turn off their engines was given a long segment

Then Prof Frank Kelly ...he wasn't terrible
There are "29,000 deaths from pm2.5"
... He's wrong to fail to fail to say that these are equivalent theoretical rather than actual deaths.
And the stat is definitely sus
Presenter jumped to conclusion that 29K fig is all attributable diesel

The word "Deadly" was used a lot
That is wrong cos normal pollution isn't deadly ..it doesn't CAUSE death like some chemicals do, rather it reduces lifespan by days.

Perspective of the DPF problem : A report was produced saying that 1,800 vehicles with removed DPF's had been found to have slipped through the MOT procedure ..This then led to them extrapolating to say tens of thousand of such vehicles must be on the road.
The prog made a big issue that although it's illegal for you to own a car with no DPF, it's not illegal for a garage to remove it, so a lot of garages advertise this fix for a car which has a problem with its DPF
Each unfiltered car produces 20 times the particulates of a proper car.
To me that would be a clear target instead of congestion zones
eg The London T-charge might reduce the number of diesels in a zone from 1,000 per day by 200, but if 10 of the remaining 800 are running without DPF then you'd be back up to equivalent particulates of 1000 vehicles.
The vehicles are easy to spot cos they emit black smoke, so is there any reason to wait for big law changes ?
Theoretically a cop could spot it and say that since the vehicle appears to have no DPF it's breaking the law and has to be tested.
OK cops have no time, but Sadiq's air marshalls could be given portable kits, and then call cops to get vehicles seized.
Special units already set up checks on motorways to inspect truck engines and it wouldn't be a big step for them to include obvious black smoke cars in that.

Emotional blackmail
Mother of dead Child living close South Circular blames diesel
..I looked it up
"Rosamund Kissi-Debrah a #cleanair campaigner, following the death of her daughter Ella"
\\An inquest into the “healthy” Holbeach primary pupil’s death found she had died from acute respiratory failure but did not establish the cause of her asthma.//
To me it's very possible that had the same child lived in the countryside she would still have died. It was something about the child that caused the death, otherwise all kids living in London would be dead.
The comments in the newspaper are skeptical also

At one point "In UK 3/4 of air monitoring stations are above UK EU guidelines"
That's meaningless cos you don't put monitors in areas where the pollution seems OK

The prog ended with a load of anecdotes from listeners.
Having that as the "take away", instead of proper science is bad.

eg1 Bronchiolitis patient said "all diesel cars should be banned"
... Well the mechanism by which people suffer is complex
A combination of weak genetics, poor medical treatment. Person X might think getting rid of diesel might be a magic solution, but it's entirely possible it makes no ifference.

eg2 Cyclist said he thinks he got motor neurone disease from frequent cycling in pollution.
.... Again this is jus empty speculation.

People are realising DieselsRpaedos rates dirty old petrol cars as better than clean Euro6 diesel
So the campaign is encouraging dirtier option.

\\ Alan Tovey 13 NOVEMBER 2017
Prices of used diesel vehicles could be “cratered” by a broad-brush regulatory regime that doesn’t discriminate between most and least polluting ­engines, it has been claimed.

Nick Molden, chief executive of the testing company Emissions Analytics and one of the harshest critics of diesel at the height of the VW scandal, has come to the defence of the fuel. His company’s on-the-road tests have found some of the most modern diesel cars, classed as meeting the Euro 6 standard of pumping out no more than 80mg of NOx pollution per kilometre, achieve far better performances.

“Some of the latest diesel cars are as good as petrol cars on pollution,” said Mr Molden, whose company has established the EQUA Air Quality Index, which gives an independent assessment of how much pollution cars emit.//

To get into this library users have to squeeze past a parked bus with it's diesel engine running.
The bus is marked "BBC"

WUWT : Does Air Pollution Really Shorten Life Spans? November 28, 2017
Guest essay by Dr. Indur M. Goklany
\\ To recap, the death toll from air pollution caused by fossil fuel combustion — and the resulting decline in life expectancy — are, to quote Mark Twain, greatly exaggerated. In fact, for whatever reason, life expectancy increases in association with fossil fuel use.

Finally, some may argue that while PM2.5 may not reduce life expectancy, it may actually make the population sicker. But this argument fails scrutiny.//
\\ In today’s world, claims of air pollution shortening life expectancy are fake news premised on fake deaths.//

LBC : 9:30am New report says
"Over-60s should avoid going for a walk on city streets as air pollution wipes out the health benefit from the exercise, research shows."
Debunked by the Essex prof brought on to comment
"The cohort is too small"
"You can't take a small group and walk them down Oxford St and then around Hyde Park, and get a proper result
, there are a number of other factors that make them different environments
... yes it is best to exercise in the park
.. there are some walking routes which are low traffic routes
.. cycle masks often make little difference unless you are using one custom fitted to your face"

Link to Imperial press release

Exposure to air pollution on city streets is enough to counter the beneficial health effects of exercise in older adults, according to new research.

The findings, published in The Lancet, show that short term exposure to air pollution in built up areas like London’s busy Oxford Street can prevent the positive effects on the heart and lungs that can be gained from walking

Context : today's WaPo news Air pollution in New Delhi is 10 times over the safe level

Government by law suit, not by vote
Client Earth now bullying Welsh Government

“People in Wales are choking on toxic fumes on a daily basis,” said James Thornton, chief executive of ClientEarth.

Really ?? name the person who choked.

Back to London pollution exercise
The prof on at 9:30am was Professor Ian Colbeck of Essex Uni

I add that the strange thing about London is that it has boroughs with low end life expectancy
yet has other boroughs which have the longest lifespan in the country.
