In a special episode, The Northern Agenda podcast takes a closer look at an issue that has reached boiling point in several cities across the North of England: the introduction of Clean Air Zones.

It is the controversial scheme where owners of the most polluting vehicles are forced to pay as much as £60 per day to enter certain roads and areas.

Political editor Jennifer Williams and local democracy reporter Dan Holland tells Northern Agenda editor Rob Parsons about the reaction to Clean Air Zones from their patches: Greater Manchester and Newcastle.

Rob is also joined by Paula Widdowson, the executive member for environment and climate change at the City of York council, who believes that her city's "voluntary" clean air zone has been successful - and whether it could be replicated across the country.

The Northern Agenda is a Laudable production for Reach. It is presented by Rob Parsons and Daniel O'Donoghue, and it is produced by Daniel J. McLaughlin.
