The National Emergency Briefing was held on in Westminster Central Hall on the 27th November 2025. Eight leading experts, chaired by Professor Mike Berners-Lee, gave a concise, high-level and unfiltered briefing on the entire interconnected crisis - including threats to food supply, health, and national security. They also set out how investing in genuine emergency action will make us better off. The event was opened by Chris Packham.

The invitation-only audience of over 1200 included politicians and influential figures from business, culture, faith, sport, and the media. A film version of the event, the People's Emergency Briefing, is now being rolled out across the UK.

The event is supported by the National Trust, RSPB, Church of England, Exeter University, the Royal Meteorological Society, Royal Society of Biology, National Education Union, and many more.
