Clean Air Zone Procurement

V4 Services are responsible for the delivery Competitive Procedure with Negotiation (CPN) for Clean Air Zone. The Government set legal limits for pollution and Bristol developed a project team to deliver to introduce a Clean Air Zone (CAZ) to ensure Bristol meets those limits within the shortest possible time.

Case Study 2 - Clean Air Zone Procurement - 800x440

A Clean Air Zone is a specific location that aims to reduce public exposure to nitrogen dioxide through:

  • restrictions on the highest polluting vehicles
  • encouraging the use of cleaner vehicles
  • encouraging people to walk, cycle or use public transports

The main CAZ approved devices tender is soon to be finalised but there are various associated contracts that need to be completed that aligned to the overall delivery of a successful CAZ for Bristol.
