Thank you for your request received by us on 19 April 2023 asking for information about ULEZ exemptions.
Your request has been considered in accordance with the requirements of the Environmental Information Regulations and our information access policy. I can confirm that we hold the information you require. You asked for:
the Criteria for a ULEZ exemption for a petrol motorcar is the NOx for any petrol motorcar being no higher than 0.08 g/km
The ULEZ charge only applies to non-compliant vehicles. There is no charge applicable to compliant vehicles and so an exemption is not necessary. The standard for compliance with the ULEZ for M1 passenger cars is 0.08g/km NOx. This applies to both petrol and diesel engines and is equivalent to the Euro 4 standard for petrol cars and the Euro 6 standard for diesel cars but there is an additional requirement to not exceed 0.005g/km particulate matter for diesel engines.
If this is not the information you are looking for, or if you are unable to access it for any reason, please do not hesitate to contact me.
Please see the attached information sheet for details of your right to appeal as well as information on copyright and what to do if you would like to re-use any of the information we have disclosed.
