Data returns

Many environmental licences include a requirement to submit data returns or other reporting requirements on an annual or quarterly basis.  

What should you do?

We are now actively reviewing many of the data returns and kindly request you to submit any outstanding returns for the following areas:

Scottish Pollutant Release Inventory (SPRI)

SPRI returns for the 2023 calendar year are due by 28 February 2024.

To streamline the return process, we will be dispatching the SPRI return forms at the beginning of January. Each site will receive an Excel form tailored to its requirements. These forms must be completed and returned via email to no later than 28 February 2024.

Please inform us promptly of any changes to your contact information to facilitate smooth communication during the return process.

If a return is not received by the due date, we will look for a suitable alternative and may contact you by phone or letter to request more information.
