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

To ask the Secretary of State for Environment, Food and Rural Affairs, whether research has been undertaken by the Government to examine the effect on air quality of roadworks; and if he will make a statement.

The Government has not conducted research specifically on the impact of roadworks on air quality. However, we recognise that while they are being carried out, roadworks can lead to congestion, which impacts on air quality as well as on people’s journeys. There are also emissions from the machinery used to carry out roadworks.
