From Fleet News today.  I've included the whole article as there is quite a bit of information in it:

 

"Transport for London (TfL) has earned £220,000 per day since the introduction of the London Ultra Low Emission Zone (ULEZ).

Drivers of older, non-compliant, cars that enter the ULEZ at any time are charged £12.50 per day on top of the £11.50 congestion charge that operates on weekdays.

New figures released by TfL show that, on average, 17,400 drivers of non-compliant vehicles paid the ULEZ charge every day in April. If non-compliant vehicles were all cars that would equate to £220,000 per day.

 

HGVs and buses that don’t comply have to pay £100 per day.

 

Almost three-quarters (74%) of vehicles entering London’s Ultra Low Emission Zone (ULEZ) in its first month were compliant with new pollution standards, according to the report.

 

The figures suggest a significant decline in the number of high-pollution vehicles entering the capital since February 2017, when only 39% of vehicles were compliant.

Sadiq Kahn, Mayor of London, said: “It's early days, but it's great to see Londoners and businesses are doing their bit to make a difference, with nearly three quarters of the vehicles driving into central London each day now meeting the standards required to turn around this public health crisis. It's vital this compliance is sustained to truly make a difference to our air quality, and as time goes on we will publish more research into the impact of the ULEZ, progressing this ground-breaking, life-saving work even further.”

 

The ULEZ operates 24 hours a day, seven days a week, 365 days a year in the central London congestion charging zone. Motorists who drive in the zone in a vehicle that does not meet the new emission standard (petrol vehicles that do not meet Euro 4 standards and diesel vehicles that do not meet Euro 6) have to pay the daily charge.

There were around 36,100 fewer older, more polluting, non-compliant vehicles seen in the zone on an average day (excluding non-typical days), a reduction of around 58% per cent, from February 2017 to April 2019.

 

This has already started translating into real-world improvements in air quality, including a reduction of approximately 20% in NO2 concentrations measured at roadside monitoring sites in the zone since February 2017.

 

TfL highlighted that around 3,000 drivers per day were in contravention of the scheme and issued with a warning notice on the first offence.

Khan has confirmed that the ultra-low emission zone (ULEZ) will be expanded up to the north and south circular from October 25, 2021.

 

Date	Number of vehicles driving in the charging zone per day during CC hours			Proportions of vehicles driving in the charging zone during CC hours
	Total number of vehicles	Non-compliant vehicles	Compliant vehicles	Non-compliant vehicles	Compliant vehicles
Feb - 17	102,493	62,310	40,184	60.8%	39.2%
Apr - 19	89,380	26,195	63,185	29.3%	70.7%

% change	-12.8%	-58.0%	57.2%	-51.8%	80.3%

...And it will cost as much to pay if you drive every day, as it would to take finance out on a modest new car that will comply!

If you can't afford the finance, you can't afford the fee so you can't afford to drive! 

As for a drop in pollutants, Not talking specific types of pollutant but generally, they ARE gonna drop now anyway as most of the huge building/regeneration of London's train stations, sewer systems, road infrastructure, cycle lanes, major building work,etc,  has taken place. There is no real way of knowing how much that added and will now no longer add, to London's congestion!

 

Remember also, for the first period of the congestion charge, the amount of traffic dropped, then went up again, bit by bit as people started to accept it. I would take any new stats with a very large pinch of sodium chloride, despite this not being a safe chemical!

So the diesels with AdBlue are compliant.

Not necessarily; PSA were using it at Euro5.

Yes.

 

This has nothing to do with improving the air quality, if it was then they would just ban non compliant vehicles completely, rather than the current approach:

 

“oh you have a dirty EU3 diesel? .... sure you can come into the LEZ, we will just charge TAX you extra for the privilege.

......for VAG that is.

That will ensure Mayor Khan enjoys a nice meal in the evening once Ramadan is over next month.

I'd be interested to know how much of the %age change over the two years was down to general modernisation of the fleet as people buy newer cars on PCP etc...   as opposed to changing specifically to comply with the zone!
