Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, whether her Department plans to issue guidance on the maximum length of time that a charging Clean Air Zone could be operated on a voluntary basis.

We will be consulting on the framework for Clean Air Zones and the secondary legislation to be introduced later this year. This will include the important principles that need to be consistent from city to city to ensure Clean Air Zones are implemented in the same way by Local Authorities across England. We will work with Local Authorities and other stakeholders to ensure that we provide the guidance they will find most relevant and useful.
