On 27 November 2025, Central Hall Westminster, London, was buzzing with an invite-only audience of around 1,250 politicians, scientists and leaders from business, culture, faith, sport and the media. Also in attendance were familiar faces like Chris Packham, Deborah Meaden, Jennifer Saunders, Mark Rylance, Brian Eno, Roger Harrabin and four of the Sussex Green Living team.
They learnt about the latest implications for health, food, national security and the economy. They weren’t there for show. They came because the National Emergency Briefing, convened by brothers Simon and Nick Oldridge, brought together some of the UK’s most respected scientific voices to share the latest evidence on nature and climate risks — with the solutions already proving effective.
