Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether she has an estimate of how much CO2 was produced in the (a) manufacture and (b) installation of one gigawatt of offshore wind power within the UK in the last 12 months.

The Department does not publish information related to this request directly, however, the IPCC and UNECE have published estimates related to this request here:

https://unece.org/sed/documents/2021/10/reports/life-cycle-assessment-electricity-generation-options

Both estimates demonstrate that the lifecycle CO2 impact of generating electricity from offshore wind is significantly lower than fossil fuels.
