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

To ask the Secretary of State for Environment, Food and Rural Affairs, whether there have been any formal complaints to the Office for Environmental Protection on exceedances of the nitrogen dioxide annual limit value in the UK.

As an independent public body set up to hold public authorities to account, the OEP does not routinely share information regarding specific complaints with Defra unless those complaints relate directly to Defra and are considered eligible by the OEP. To date, the OEP has notified us of one complaint in relation to this topic. The OEP publishes a quarterly complaints report on their website providing an overview of the complaints received and ongoing enforcement activity. They also publish information relating to individual casework where investigations have been launched and resolutions achieved.
