Scotland Leads the UK’s £105bn Net Zero Economy on Value

Scotland generates more value per worker in the UK’s net zero economy than any other part of the country, according to new figures from the Energy and Climate Intelligence Unit (ECIU), a non-profit that tracks climate and energy data. The wider sector now underpins £104.7bn of gross value added (GVA, the measure of value an industry adds to the economy), about 3.8% of UK output, and 1.1 million jobs. That puts the green economy at roughly the scale of the country’s engineering and architecture base.

Behind the rankings sits a £455bn pipeline of clean-power projects, and the report’s own contributors warn the grid, the planning system and the skills market are not yet built to deliver it. The value is already on the books. Turning it into the next decade of construction is the part nobody has solved.

The Value Map Tilts North and to the Regions

The analysis, run by CBI Economics and The Data City for the ECIU, counts around 23,500 UK firms working directly on cutting emissions or supporting the switch away from fossil fuels. Those companies produced £36.7bn of GVA in 2025 and employed roughly 308,000 full-time staff. Dig below the national total and the value clusters in places far from the capital. The energy hubs of Scotland and the industrial belts of Yorkshire, Wales and the East Midlands return higher GVA per employee than anywhere else in the country, per ECIU’s analysis of the UK’s low-carbon firms.

Scotland comes out as the most specialised nation on a relative basis, carried by offshore wind, hydrogen and energy storage. The Scottish Central Belt alone accounts for 5.2% of UK net zero GVA, and the analysis credits it with £1,915 of GVA per employee, the strongest leverage of any local cluster.

The report names six billion-pound hotspots where activity concentrates into real output:

• Scottish Central Belt – offshore wind, hydrogen and storage developments
• Birmingham to Coventry corridor – low-carbon manufacturing
• West and North Yorkshire – industrial decarbonisation and renewables
• Bristol and Somerset – clean-tech and engineering services
• North Wales and Cheshire – manufacturing tied to large renewable projects
• Greater Thames Valley – infrastructure and supply-chain firms

Yorkshire and the Humber shows how dense this can get. Its net zero economy supports more than 79,000 jobs and makes up 4.4% of local GVA, the highest share of any English region.

Why a Worker in the Sector Is Worth £119,300

The standout figure in the data is not the headline £105bn. It is what each job produces. A full-time post in the net zero economy generates £119,300 in economic value, about 48% more than the UK average, according to the CBI Economics modelling behind the report. That density feeds through to pay packets and into the rest of the economy.

Three numbers carry the productivity case:

• £1.85 generated elsewhere in the economy for every £1 the sector produces directly, through supply chains and spending
• £43,142 average full-time wage, 11% above the national average of £39,039
• 96% of the firms involved are small and medium-sized businesses, not large corporates

Read together, those figures explain why a region with relatively few green firms can still top the value table. Offshore wind, hydrogen and grid-scale storage are capital-heavy and skill-heavy. They put fewer people on the books than retail or hospitality, and each one moves a lot more value. Scotland’s lead is a measure of what its workers build, not how many of them there are.

London Has the Companies, the Regions Have the Output

Geography splits the economy in two. London and the South East hold the most net zero businesses, roughly 8,900 in the capital and 7,400 across the South East, mostly finance, professional services and corporate headquarters. The physical work, and most of the value per head, sits elsewhere. The contrast is sharp enough to set out plainly:

This is the kind of regional spread ministers have been chasing for a decade. The capital bankrolls and advises; the energy and industrial regions manufacture, install and connect. Scotland’s offshore strength shows up clearly in the breakdown of Scotland’s net zero output, where wind and storage do the bulk of the lifting.

A £455bn Pipeline Waiting on the Grid

The forward number dwarfs the current one. The UK’s renewable pipeline represents a £455bn investment opportunity across 262GW of capacity, and two-thirds of that is already in active development or under construction. That is the prize the value table is really pointing at. Whether the country can capture it comes down to plumbing the system can’t yet handle.

Engineering consultancy AtkinsRéalis, responding to the report, put the warning bluntly through its market director for power, renewables and industrial, Ryan Macdonald.

Demand from electrification, industry and new technologies is accelerating faster than the system can respond, with constraints around grid capacity, planning, skills and supply chains increasingly coming to the fore.

Grid Connections Are the Bottleneck

A wind farm or storage site only counts once it can export power, and queue times for grid connections have become the binding constraint on UK renewables. The 262GW in the pipeline assumes the network can take it. Much of that capacity sits in Scotland and the North Sea, far from the southern demand centres, which means new transmission as well as new generation. Build the turbines without the wires and the value stays theoretical.

Skills and Supply Chains Lag Demand

The second constraint is people. Macdonald argued the answer comes down to capability: investing in skills, strengthening supply chains and moving talent across sectors to deliver at scale. The sector’s high productivity cuts both ways here. Jobs worth £119,300 each need trained engineers, welders and project managers, and those are exactly the workers in short supply as electrification accelerates.

Small Firms Are Doing the Heavy Lifting

For all the talk of offshore megaprojects, this is an economy built on small businesses. More than 96% of the firms in the data are SMEs, fitting solar panels, making parts for electric cars, servicing heat pumps and handling the unglamorous work that adds up to a transition. ECIU director Peter Chalkley called them the sector’s unsung heroes in ECIU’s figures on the net zero workforce, and his pitch is about certainty more than cash.

Small firms commit to hiring and kit on the assumption that policy holds. Chop and change the rules on heat pumps, electric-vehicle targets or grid support, and they pull back first. That fragility runs through parts of the supply chain already, including waste and recycling, where Scotland is already wrestling with a shortage of domestic reprocessing capacity as high-value material heads abroad.

CBI chief economist Louise Hellem framed the stakes around competitiveness, arguing the UK “cannot afford to step back from an industry already contributing £100bn to the economy and with huge future growth potential.” Global rivals are scaling fast, and the report lands as a £455bn build queue waits on decisions about networks, planning and training that government and industry have yet to settle. The value Scotland has banked is real. The next decade of it is sitting in a grid connection queue.
