ATISN 16410 – Chemical Spraying UK

Information requested

Thank you for your request which I received on 16 June 2022.  You asked for:

Information on the spraying of chemicals in the skies of the UK; the contents and purpose of such spraying and any research relating to the health and safety impacts of such a programme.

Our response

Following a search of our paper and electronic records, I have established that the information you require is not held by the Welsh Government. 

The activity you describe in your email would be classified as Geo-engineering.  Such matters are not devolved to Welsh Government but would come under the UK Government’s Department of Business, Energy and Industrial Strategy (BEIS).  May I refer you to their policy paper ‘Geo-engineering: the government’s view’ which can be found at this link Geo-engineering : the government’s view

BEIS FOI contact point can be reached via:

Information Rights and Records Unit
1 Victoria Street
United Kingdom

Or by e-mail at

I hope this offers some reassurance that the Welsh Government is not undertaking the activities such as you have described and as far as we are aware nobody is in the UK. 

Next steps

If you are dissatisfied with the Welsh Government’s handling of your request, you can ask for an internal review within 40 working days of the date of this response.  Requests for an internal review should be addressed to the Welsh Government’s Freedom of Information Officer at: Information Rights Unit, Welsh Government, Cathays Park, Cardiff, CF10 3NQ or Email:

Please remember to quote the ATISN reference number above.   

You also have the right to complain to the Information Commissioner.  The Information Commissioner can be contacted at: 

Information Commissioner’s Office, 
Wycliffe House, 
Water Lane, 
SK9 5AF 

However, please note that the Commissioner will not normally investigate a complaint until it has been through our own internal review process.

Yours sincerely
