New emmissions tests

[Kremmen]

....starts on the 29th November 2026. I didn't know that the UK has helped develop this standard through the United Nations Economic Commission for Europe (UNECE).                                                                                                         

Has everybody got their ducks in a row for the new emission tests? from what I've been reading if the vehicle doesn't emit exactly the same emissions as when it was built the car will be banned from any use on the road even if it passed its MOT emissions
If this is correct it will effectively destroy a majority of the car industry as car tuning and modification will stop you being able to drive your car on the public highway

This is targeting all vehicle, cars, motorbikes, trikes, kit cars etc.
So far they are just targeting cars after 2001 but they want to use it on every vehicle on the road targeting mot & tax exempt (historic) vehicles. I don't know how they'll be able to check historic vehicles as they're just a visual check.   https://www.gov.uk/government/consultations/in-use-emissions-of-road-vehicles-regulating-environmental-impacts

This isn't law... yet. It is a proposal that was out for public consultation which they are now assessing. Depending on the feedback and any further changes and exemptions it won't become law unless it is passed in the summer of 2027 and there is a planned 6 months lead time to allow any adjustments that vehicle owners may need to make.

I don't know where the November 2026 date has come from from?

As long as my car passes in four weeks time, I don't care.  My EV is due for delivery in January .

I read the other day that over a third of new cars sold are EVs.

Regardless of how the proposed regulation is worded, one aspect that I have not yet seen discussed is how the original type approval (TA) values would be determined by in-service testing. TA is conducted by a small number of designated and accredited test houses under laboratory conditions and real-world simulations using complex (and expensive)  equipment and measures emissions in terms of grams per kilometre. This takes some time to perform. Emissions measurements for MOT testing is quite different and I have yet to find out how MOT levels were derived from or correlate with the TA requirements.

In view of this, how would the authorities determine whether a vehicle continues to meet the levels measured by the TA assessment? DPF, Catalytic Converter or AdBlue deletion should be fairly obvious. Gaseous and particulate emissions in terms of TA (not MOT) levels is not (currently) something that can be determined at the roadside or by a MOT test station.

One method which is already in use in Finland, is to connect a diagnostic device and see if the engine management software is OEM or tampered.
