$600B Green UK Economy: We Mapped the South West's Surprising Role
Updated: Aug 1
We assumed the South West's biggest green strength would be energy. After tagging tens of thousands of research outputs across ten years, energy came third. Here's what we actually found - and why it matters more than the obvious story.
The UK is lining up something enormous.
An estimated £455 billion of investment* is in the pipeline for the country's green build-out over the next decade - wind, tidal, grid, the lot. It's one of the largest infrastructure undertakings in modern British history.
But there's a part of that story nobody really talks about. None of it happens on its own. Every turbine, every grid upgrade, every clever piece of engineering rests on something quieter and slower: the ideas. The science. The people who spent years working on this before anyone was paying attention.
That £455 billion is the national build-out. The research is the supply side that feeds it. And we wanted to know one specific thing: what's actually being worked on, right here in the South West of England?
So we mapped it. Ten years of research. Tens of thousands of outputs. And honestly - the answer surprised us.

The South West is a bigger green player than you think
When people picture where the UK’s green economy lives, they tend to look north - Teesside, the Humber, the big industrial clusters and offshore wind farms. That's fair, but it misses something.
The South West - Bristol, Bath, Exeter, Plymouth and everything between - quietly sits among the three largest net-zero hotspots in the UK, according to CBI Economics and the Energy and Climate Intelligence Unit. Not a footnote. A leader.
We've been circling this story for a while. If you've seen our films on Bristol's deep-tech scene or why its supercomputer matters more than London's, this is the bigger picture they were pointing at. But this time we wanted to go underneath the companies and the headlines, to the raw material itself: the research.
What we actually did
In plain terms: we pulled together a decade of academic research coming out of the South West - tens of thousands of papers, projects and outputs - and tagged every one of them. By theme. By institution. And by how close each piece sits to something you could realistically build a business on.
The goal was simple. Stop guessing what the region is good at, and look at the evidence instead.
Before we tagged a thing, we made a bet. We assumed the answer would be energy - offshore wind, tidal, maybe some nuclear with Hinkley down the road. It felt obvious.
We were wrong.
The surprise: energy came third
When the data came back, energy wasn't first in terms of filtered publications. It wasn't second either. Energy came third.
The single biggest strength in the South West, by a clear margin, was climate data - measurement, monitoring, forecasting. The science of understanding what the climate is actually doing.
Second was food, agriculture and land use - how we grow things, manage soil, and use the land itself as part of the solution.
And third, energy and the power transition.
Climate data, monitoring & carbon - 33%
Food, agriculture & land use - 26%
Energy & power transition - 19%
Sit with that for a second and it stops being surprising - it starts making complete sense.
Plymouth holds one of Europe's great marine research traditions. Exeter sits right next to the Met Office, one of the most important climate-forecasting institutions on the planet. And the wider region carries a deep agricultural research heritage across its farmland.
Of course the South West is a climate-data powerhouse.
Exeter is an anchor
One place kept rising to the top: Exeter.
Of all the major institutions we mapped, Exeter had the highest proportion of genuinely relevant research - the highest "keep rate," in our terms.
Combined with climate data being the number-one theme overall, the picture is hard to miss. Exeter is the gravity well: a regional capital for understanding the climate itself.
That Met Office connection isn't a coincidence; it shows up clearly in the data.
Emerging research: cooling poverty
The result I keep coming back to is a smaller one.
While tagging, certain themes kept surfacing that didn't fit neatly into any of our categories = the interesting strays. One appeared again and again: cooling poverty.
It's a deceptively simple idea. As the world warms, staying cool stops being a comfort and becomes a question of survival. And just like heating, the people who'll struggle most to afford it are the ones with the least.
It's barely funded, barely discussed = and it's being seriously studied, right here in the South West.
That's the kind of thing you only find by casting a wide net and actually looking, instead of searching for what you already expected to find.
How much of this could become real?
A fair question: how much of this is just papers, and how much could become something tangible?
We looked at that too, and we were honest about it. Roughly a quarter of the climate-relevant research we mapped is what you'd call applied - close to the ground, the kind of work that could plausibly become a product, a patent, a company.
A quarter might not sound like a lot. But across a dataset this size, that's thousands of pieces of genuinely commercialisable research - many of which no investor has ever laid eyes on.
And that's really the point. That £455 billion build-out needs a pipeline of ideas to draw on. The South West is quietly sitting on one.
What we're building next
We're turning all of this into an interactive map of the South West's green research ecosystem - every theme, every institution, with the applied, commercialise-able work pulled out and made searchable and live.
So founders, investors and researchers can finally see what's actually here. It's the thing we wish had existed when we started asking these questions.
It's not public yet. But you can be first in.

You'll get in the moment it opens.
We came into this expecting a story about energy. What we found was a region that understands the climate better than almost anywhere in the UK - quietly feeding the green economy of the next decade, and mostly unmapped until now.
The South West has been underestimated for a long time. We don't think it will be for much longer.
Methodology & sources
We compiled academic research outputs associated with South West institutions over a ten-year period and tagged each by theme, institution, research type and commercial readiness.
Pillar shares reflect the proportion of relevant ("kept") outputs in each category in our current dataset and may shift as the dataset is refined. We describe the corpus as "climate-relevant research outputs" - a deliberately wide net that includes foundational, data and applied work, not a count of discrete innovations or breakthroughs.
