The National Emergency Briefing is the result of leading experts and concerned citizens joining forces to encourage UK decision-makers to step up their response to the escalating climate and nature crisis. It started with a prime-time televised emergency briefing to the nation and a wide range of groups and organisations are now using NEB materials for local meetings including screenings of the NEB film. The NEB provides the film, guidance, graphics and other supporting resources, but the overall approach is deliberately decentralised.
