UK Government Rejects Sun-Dimming Scheme, Keeps Focus on Net Zero

Britain’s Department for Energy Security and Net Zero formally stated that the government will not support or implement solar radiation management technologies aimed at reflecting sunlight away from Earth. The decision follows criticism that such schemes are “crack-pot” and waste taxpayers’ money. Although deployment is ruled out, Whitehall earmarked £56.8 million for research on climate-cooling concepts via the Advanced Research and Invention Agency, including projects on cloud seeding and electrified clouds, while prohibiting toxic or large-scale field trials.

The Royal Society warned that SRM could disrupt rainfall and trigger droughts, and the Ministry of Defence has also funded related studies. Researchers at the University of Cambridge welcomed the cautious stance, noting the need to understand risks before any future use. Net Zero remains the government’s top priority, focusing on reducing emissions rather than speculative geo-engineering.
