Question reference: S6W-12542

  • Asked by: Liam McArthur, MSP for Orkney Islands, Scottish Liberal Democrats
  • Date lodged: 24 November 2022
  • Current status: Answered by Mairi McAllan on 9 December 2022


To ask the Scottish Government how many incidents have been recorded of sulphur hexafluoride (SF6) escaping from (a) onshore and (b) offshore power generation sites in each of the last three years.


The Scottish Government does not hold recorded information on the number of leakage incidents of sulphur hexafluoride (SF6) from onshore and offshore power generation sites that have been recorded in the last three years.

The Scottish Government is aware of the impact of this potent greenhouse gas on the environment and of the risk of leakage incidents. We are currently working with the UK and Welsh Governments to review the F-gas Regulation. We have already done a retrospective assessment of the Regulation and will publish an assessment report on the findings in the coming weeks.

Following the report, we will jointly consider policy options to ensure our regulations continue to support our ambitious Net Zero targets. As part of this, we will also consider other important issues including leakage. We expect to publish a joint consultation on these future policy proposals in due course.
