Information requested

I was wondering if I could obtain a copy of the original ONR Position Statement on use of UKCP2018.  I would like to compare the original against Rev1 to see the changes between the two documents.

Use of UK Climate Projections 2018 (UKCP18) - Revision 1, November 2020 (

Information released

I can confirm that under Section 1 of the FOIA we do hold the information requested.

Please find attached the document you have requested:

As you are aware, the above document has been replaced by the revision entitled ‘Use of UK Climate Projections 2018 (UKCP18) Revision 1’ and is available via our website.

The ‘Use of UK Climate Projections 2018 (UKCP18) Position Statement’ has been updated to provide further clarity on the regulators’ expectations for the use of UKCP18 and to incorporate UKCP18 developments since March 2019, including the release ofthe 2.2 km local projections. Revision 1 also includes the expectations of the Scottish Environment Protection Agency (SEPA).
