So what do we think of diesels now?

Light aviation contributions to pollution are so small as to be insignificant, I did see figures that suggested that the annual U.K. GA fuel burn was equal to the fuel burn for an hour on the M25 at rush hour.
I don't know the sorce of these numbers but I think it sums up the scale quite well.

I just read in a German newspaper they plan to ban Diesel powered cars from Stuttgart if they do not comply with Euro 6 regulations - their contribution to pollution in that town was estimated to be less 5% ... It is all about ideologies, not reality. I will be allowed to burn 100LL on top of their heads, but can not take the 2 year old car of my friend there to drive into town?

Alright, I'll continue the thread drift; can someone fill me in on how diesel cars are so bad that cities are looking at measures to ban them?
Diesel CO emissions are half of petrol, diesel particulates (the sooty stuff?) is the same, but their NOx levels are slightly higher.
I believe the NOx / CO difference is down to the difference in the chemistry of petrol / diesel burn, but I'm open to being educated.

Second, NOx is that tad higher that Diesel qualifies as "we make the world better" pretend-carrier.
Third, a problem is soot. As long as we had the old Diesel engines, soot was only a problem for the mom with her clotheline very close to the streets, but - every dumb idiot was able to see the black stuff. Then they invented the Diesel cat, the visible soot disappeared, but the physics got a lot worse as Diesels now produced tiny and airborne particles instead of the black rocks collected at the curbstone. They invented a bigger problem by solving a visible unseemliness. Then somebody even found out that tiny particles could have a medical impact and boom, next wave. Had they left it at the old soot throwers, we would not face the problem.

A scientific adviser, who has now admitted that he was wrong, was driven by an obsession with carbon emissions.
Can we really believe any of those characters? Do they first come up with a conclusion and then go about 'proving' it?
Glad to see that the PM is, at least, talking the talk; we shall see if she puts rhetoric into practice and stands up to money grabbing city councils.

Southampton has spent years solidifying the traffic in order to justify a congestion charge. I shall be keeping my twenty year old Diesel. It will cost the planet much more to melt it down and replace it than it will ever pollute.

100LL is widely available in Europe and the USA but in most of Africa it is virtually unobtainable, making GA impossible without having 200 litre drums trucked in to any airfield that you plan to visit in advance and at great expense.
Diesel engines for light aircraft are the only way forward in these areas and they are becoming increasingly popular.

More thread drift ☺
Received new format AOPA members magazine at weekend. Looks a nice "face-lift" to mag and includes an article talking about Warter being the only producer of UL91? I thought there were other players .....Total, Air BP etc but notice less and less airfields stocking, and no longer any price advantage. But a question I never really got the answer to, is whether by running my O-360 on UL91, do I get any less power output? Without any price difference is there any remaining advantage with the exception of being green?

Most of these policies are driven by green campaigners, many of whom make snake oil salesmen look respectable. The difficulty is that quite often they demand that something be banned e.g. Lead in petrol. However they don't then follow through and consider whether the solution (carcinogenic additives and CAT full of toxic heavy metals) might be worse than the problem.
I want one of these:
Steam Car Club Dobles
But with a slightly more modern body, chassis, brakes, suspensions, etc.

The stat I saw was that the total fuel that evaporates from Car fuel tanks via the breathers exceeds total consumption of 100LL across the whole of Europe.
The system is called Evaporative Vapour Emission Control (EVAP) and is one of the earliest emission control systems fitted to petrol-powered vehicles.
The primary vapour control device is a charcoal-filled canister that is fitted either in the engine bay, or close to the fuel tank.

The air in Putney high street is among the most polluted in London. Despite the introduction of hybrid buses, the mayor has taken to rerouting them to avoid the worst spots. There are calls to scrap all of London's diesel buses, but what would you do with all of them?

Did facts ever keep politicians away from stupid decisions?
I just read in a German newspaper they plan to ban Diesel powered cars from Stuttgart if they do not comply with Euro 6 regulations - their contribution to pollution in that town was estimated to be less 5% ... It is all about ideologies, not reality. I will be allowed to burn 100LL on top of their heads, but can not take the 2 year old car of my friend there to drive into town?

Personally speaking (and that's only cos I drive an EU6 car) I'd prefer that approach than that favoured by our favourite deluded hypocrite Khan, saying he's going to charge 24 quid a day for diesels to enter his Londonistan, irrespective of emissions. As if a tax ever helped the environment......
What I find interesting is that your friend's two year old car doesn't meet the limits for the EU6 regulations, but my 3 year old car does......

Removing HGVs from roads would help. Unfortunately, petrol engines aren't really an option for heavier vehicles.

The 'scientific adviser' who was wrong, is a long time proponent, adviser and activist on climate change !

Incidentally, global warming induced changes, such as the meandering jetstream, and increased water vapour in the atmosphere, are not going to improve flying conditions for GA.

There is a common view that the risks of climate change are of such an existential nature that it is worth taking significant pain now (local pollution, forgone development, lower material output, etc, - but not the use of nuclear power) to attempt to reduce the longer term impact. I suspect it was this conscious trade-off that drove the recommendations.
