Breaking down the evidence on Britain's environmental future, and what it means for you.
What is the National Emergency Briefing?
On the 27th November 2025, ten of the UK's leading climate and nature experts stood in front of more than 1,200 politicians, business leaders, faith leaders and media figures in Westminster and told them, in plain terms, what the evidence says about Britain's environmental future [1]. The event was called the National Emergency Briefing, presented by naturalist Chris Packham. It wasn't a protest or a lobbying stunt, rather a brutal insight into the realities of what the UK might face soon, putting the evidence in front of the people who make decisions and let them decide what to do with it.
How did one evening in Westminster turn into a nationwide campaign?
After the Westminster event, organisers turned the evidence into a documentary and started touring it around the country. By June 2026, over 1,600 screenings had taken place in village halls, cinemas, workplaces and community centres, under the banner of the People's Emergency Briefing [1][2]. The point was to get constituents and their MPs in the same room, hearing the same evidence together, rather than arguing about it second-hand. A parliamentary petition calling for a UK wide televised briefing passed 100,000 signatures and triggered a debate in Parliament, a sign of how much appetite there is for straight answers over politics as usual.
What did the experts tell Britain's leaders?
Professor Nathalie Seddon told the room the bleak reality. The UK sits in the bottom 10% of countries globally on the Biodiversity Intactness Index, with only around half of the country's original nature left intact [3]. The Environment Agency's own flood risk assessment backs this up. One in four properties in England, around 8 million homes, could be at risk of flooding by 2050, and current infrastructure wasn't built to cope with it [4]. Professor Kevin Anderson warned that without faster action, warming could reach 3 to 4°C by the end of the century, a scenario scientists associate with a serious risk of societal breakdown [3]. Professor Paul Behrens noted that roughly a third of the UK's food price inflation in 2023 came from extreme weather rather than supply chains or wages [3]. And Professor Hugh Montgomery made the case that tackling obesity through more sustainable diets could save the UK around £126 billion a year, reframing climate action as an economic win rather than a sacrifice [3].
None of this is only a Westminster conversation. At London Climate Action Week this summer, speakers made much the same point from different angles. Asad Rehman of Friends of the Earth spoke about the 13-year gap in life expectancy between richer and poorer London neighbourhoods, driven by air pollution, a lack of green space and other local, climate related conditions. Professor Montgomery, speaking again at the same event, put it starkly. "We're in a heatwave, yet this is the best summer we'll have for the rest of our lives as we know it." The message lines up either way. This isn't an abstract, future problem, it's already showing up in people's health, homes and bills.
What does this mean for SMEs and everyday UK businesses?
New UK Sustainability Reporting Standards come into force from 2026, and it's a gap many SMEs are keen to close. Research from Aldermore Bank found only 13% of UK SMEs currently feel genuinely prepared for net zero, and many business leaders are still getting to grips with the difference between their Scope 1, 2 and 3 emissions, with 82% wanting more clarity on how to turn these requirements into an opportunity rather than a barrier [5]. That's arguably the most telling figure, because the same research found small businesses could unlock an average of over £52,000 in additional annual revenue through sustainability improvements, and there's clear appetite to invest further in getting there [5].
Then there's the physical risk aspects. With flood risk climbing and extreme weather already pushing up food and energy costs, SMEs in agriculture, hospitality, retail and logistics are carrying costs that rarely show up on a standard risk register. Angela Francis of the Climate Change Committee told the briefing that the whole net zero transition is now estimated to cost the UK around £4 billion a year, roughly 0.2% of GDP, and that figure has fallen 73% from projections made just five years earlier as clean technology got cheaper faster than expected [3]. For businesses weighing up when to invest, that's a reasonable argument for moving early rather than waiting for costs to rise.
One practical step is sitting right there for the taking. The National Emergency Briefing film is accessible to stream anywhere, workplaces, village halls or cinemas. Getting your team in a room to hear the 45 minute evidence-filled film together tends to do more for buy-in than another sustainability memo, and it's a straightforward way to start the conversation before the 2026 reporting standards force it. If you're looking for a low cost first move, booking a screening for your workplace is a good one.
So what should the new Labour government do?
With a new Prime Minister and changes being made politically, this is where the live political fight sits. Former Prime Minister Tony Blair recently argued the climate debate has become "irrational" and that Britain should focus on technology such as carbon capture rather than cutting fossil fuel use, a position Downing Street was quick to distance itself from, even while insisting its own net zero policy wouldn't require financial sacrifice [6]. Meanwhile the Climate Change Committee, the government's own independent adviser, says progress preparing the UK for climate risks has been limited [6]. That gap between reassurance and readiness is exactly what the National Emergency Briefing is trying to close.
There's a reasonable case for Labour to move faster in a few areas. Bringing flood defence funding in line with the Environment Agency's updated risk figures, rather than older ones, would be a start. So would giving SMEs proper practical support, not just reporting deadlines, ahead of the 2026 standards. It would also help to be transparent with the public about the fact that delaying action is usually the costlier option The figures above suggest the old argument that net zero is unaffordable doesn't hold up as well as it used to. The harder political job now is building public confidence, not making the economic case.
The bigger picture
One thing that came up repeatedly at London Climate Action Week was the gap between people who work in this space and everyone else. There's a real difference in understanding between people who follow climate and nature issues closely and the average person who wants to care but feels overwhelmed by the scale of it. That gap is exactly why we write jargon busters like this one, and why our business and impact newsletters exist too, so this kind of briefing doesn't stay locked inside a room in Westminster.
At ZeroBees, we think understanding what's being said, and what it means for your business, should be accessible to your priorities. That's why we help SMEs translate evidence like this into practical next steps, from making sense of new reporting standards, to spotting where your operations carry the most climate risk and opportunity, to building a sustainability approach that actually fits your business. Whether you're starting out or refining an existing plan, we're happy to help.
