National Emergency Briefing

On 27 November 2025, ten of the UK’s leading experts briefed an invited audience of more than 1,200 politicians and leaders from business, culture, faith, sport and the media in Westminster.

The briefing set out the implications of climate and nature breakdown for health, food systems, national security and the economy, and did so on the public record. Its purpose was to demonstrate what a clear, evidence-led national emergency briefing could look like and why it is needed.

There is clear evidence that emergency action will strengthen our national and economic resilience and improve lives. But first, our politicians need to see strong support from the public. The National Emergency Briefing is designed to help create a societal tipping point towards the genuine emergency action now needed. You can help make this happen.
