Question to the Department for Science, Innovation & Technology:

To ask the Secretary of State for Science, Innovation and Technology, what discussions he has had with the UKRI on its funded research projects on solar radiation modification.

The Department engages regularly with UK Research and Innovation (UKRI), and its constituent Councils, on a range of research and innovation priorities.

In April 2025, UKRI’s Natural Environment Research Council (NERC) invested £10 million in four research projects on solar radiation modification (SRM). These projects cover stratospheric aerosol intervention; marine cloud brightening; the environment’s response to SRM; and the cooling potential of lesser-known SRM approaches. These projects will not involve outdoor experiments.
