Hertfordshire County Council and the Borough of Broxbourne are proposing to implement a Clean Air Zone (CAZ) on the A10 north of the M25. This is key part of the road network and acts as a feeder route to the M25. The need for this is based on nitrogen dioxide (NOX) levels exceeding legal limits and will mean charging of some vehicles.

That’s despite the fact that there is no clear evidence that NOX is damaging to health. See our document Air-Quality-and-Vehicles-the-Truth for explanation which has recently been revised to include the latest information.

More details of the proposals and a public consultation will follow in due course with implementation by 2022. Readers should make sure they oppose this latest proposal to damage the road network and make life more difficult for road users.
