The question

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made on the potential impact of solar radiation modification on the environment.

Answered by Kerry McCarthy

The Government is not in favour of using Solar Radiation Modification. Given the significant uncertainty around the possible risks and impacts of deployment on the climate and environment, the Government is not deploying SRM and has no plans to do so.

The Department works closely with the research community to evaluate the latest research on the potential impact of solar radiation modification on the environment.
