Britons are already taking big steps towards greener living. According to the Office for National Statistics, around 84% of adults in Great Britain reported making at least some lifestyle changes to help tackle environmental issues. And while only 53% named climate change and the environment among the most important issues facing the UK, that still leaves a clear majority adapting how they live, whether out of conviction or because the systems around them nudge them that way. That second part matters: a lot of everyday green behaviour is shaped locally, as councils make the sustainable choice the default one through kerbside recycling collections, charge points, cycle lanes, clean air zones and planning policy.
So, to pinpoint the UK cities that have taken the most steps toward greener, cleaner living, we looked at nine key sustainability metrics across 94 urban areas, including carbon emissions per capita, air quality, household recycling, solar uptake and access to green space. We also factored in full-fibre broadband coverage, as the digital backbone behind the smart energy and waste systems that help cities cut consumption and emissions.
The result is a league table that rewards mid-sized cities over the household names. Each city received a score out of a theoretical maximum of 100 points, and Exeter came closest, taking the crown ahead of Cambridge, while London lands at #28 and Birmingham at #57.
Green Britain Tilts South: 12 of the Top 15 Sit Below the Midlands
When it comes to sustainability, the map skews decisively South West. This region places five cities in the top 15, all helped by high solar uptake, comparatively clean air and shorter distances to the nearest park. The East of England follows with three entries, all of them commuter-belt or tech-corridor towns where charge point rollout has moved fast.
Scotland and Wales punch above their weight too, with two entries each, benefiting from a structural advantage the rest of the top can’t match: cleaner air in the Scottish cities and a decade of statutory recycling targets in the Welsh ones.
1. Exeter
Exeter tops this year’s ranking, and it does so without leading a single category outright. The Devon city is the most consistent performer in the study: 2.33 tonnes of CO2 per resident (the 8th-lowest figure nationally), the 9th-cleanest air in the country, with fine particle pollution averaging 5.52 micrograms per cubic metre, and 101.5 solar PV installations per 1,000 households — the 4th-highest uptake in the UK.
Exeter households have adopted rooftop solar at roughly double the national middle of the pack, and the city pairs it with 239 public EV chargers per 100,000 residents and an eco-friendly car share of 24.7%. Home to the Met Office and a university with a serious climate research footprint, Exeter has the institutional density you’d expect behind those numbers. Of course, it isn’t flawless — household recycling rate at 36.9% ranks 43rd, and full-fibre coverage of 78.8% (a key enabler of smart energy and waste systems) puts it 51st.
2. Cambridge
Trailing by nearly seven points, Cambridge builds its case on what people do for a living. A remarkable 63.1% of the city’s full-time equivalent workforce is employed in the ten lowest-emission industries — second only to Hemel Hempstead nationally — reflecting an economy built on research, life sciences and software rather than carbon-heavy sectors like manufacturing and heavy industry.
The infrastructure keeps pace. Cambridge posts 289.9 public EV chargers per 100,000 residents (6th nationally) and 90.4 solar installations per 1,000 households (6th), alongside 88.3% full-fibre availability. Granted, the air is a weak point: fine particle pollution levels place the city 73rd, a reminder that a low-carbon jobs base doesn’t automatically translate into clean local air when you sit in the flat, still-air East of England.
3. Milton Keynes
Rounding out the podium, Milton Keynes is the most infrastructure-forward city in the top 10. Built from scratch as a planned new town in the late 1960s, Milton Keynes has a grid layout that has always made it an easy testbed, and the data reflects it: 40.8% of cars registered locally are hybrid, plug-in hybrid, fully electric or range-extended — the 4th-highest share in the study — supported by 328.6 public chargers per 100,000 residents.
Milton Keynes also gets the boring things right. Household recycling sits at 51.9%, the 5th-best rate nationally, and full-fibre coverage reaches 95.7% of premises, 4th in the UK. Its redway network and extensive parkland keep residents within 473 metres of the nearest park or public garden. Where the city loses ground is carbon emissions: 3.01 tonnes per resident ranks 52nd, a consequence of car-oriented design that no amount of charge points fully offsets.
4. Watford
Not to be outdone, Watford secures fourth place on the strength of one extraordinary number. The Hertfordshire town has 672.8 public EV chargers per 100,000 residents — second only to Coventry, and more than triple the figure for most cities in the top 20.
Watford backs that up with 2.40 tonnes of CO2 per capita (11th-lowest) and a median walk of 368 metres to the nearest park, helped considerably by Cassiobury Park on its western edge. At the same time, Watford is the clearest example in this study of public infrastructure outpacing what happens at home. While charge points have gone up across the town, residents have been slow to install their own clean energy: rooftop solar uptake of 26.1 installations per 1,000 households ranks 92nd out of 94. Air quality is another weak spot, with fine particle pollution (PM2.5) levels ranking 89th.
5. Edinburgh
The Scottish capital is the highest-placed large city in the ranking, largely due to its excellent air quality. Edinburgh has the 4th-lowest level of fine particle pollution nationally, and residents live a median 322 metres from the nearest park or public garden — the 10th-shortest distance in the study.
Add a workforce that is 58.5% concentrated in low-emission industries, and Edinburgh looks like a city whose geography and economy pull in the same direction. Its low emission zone, enforced since 2024, tightens the picture further. Where the numbers wobble is energy and carbon emissions: 3.25 tonnes of CO2 per resident ranks 69th, and solar uptake of 38.9 installations per 1,000 households sits at 67th — Scotland’s tenement-heavy housing stock and cloudier skies both weigh on rooftop adoption.
6. Swansea
Swansea claims the single most decisive result in the entire study: a household recycling rate of 71.7%, the highest in the UK and nearly 20 percentage points clear of the best English performer. Wales has spent more than a decade under statutory recycling targets, and Swansea is what that policy looks like at the top end.
The city’s air quality is nearly as strong, with fine particle pollution levels ranking 3rd-lowest nationally. Otherwise, Swansea’s profile is more modest — 146.4 chargers per 100,000 residents and an eco-friendly car share of 13.1% both sit mid-table — which makes its overall position all the more notable. Bay-side geography and a compact urban core do a lot of the heavy lifting here.
7. Glasgow
Scotland’s largest city lands seventh with a profile that would have surprised anyone assessing it 20 years ago. Glasgow now records 2.70 tonnes of CO2 per resident, the 30th-lowest figure nationally and well below several southern commuter towns, alongside the 5th-cleanest air in the UK.
The COP26 host also posts 91.5% full-fibre availability and a workforce 54.7% concentrated in low-emission industries. Let’s not sugarcoat it, though: household recycling of 30.6% ranks 68th, one of the weakest results among the top 20, and solar uptake of 33.5 installations per 1,000 households sits at 81st. Glasgow’s decarbonisation has come largely through deindustrialisation and energy mix — the household-level behaviours are still catching up.
8. Reading
Reading’s position is built on the two metrics that carry the most weight in our study. The Thames Valley city emits 2.36 tonnes of CO2 per resident, the 10th-lowest in the study, and employs 58.1% of its workforce in low-emission industries — a direct reflection of the tech and professional services cluster along the M4.
Digital infrastructure is similarly strong at 94.8% full-fibre coverage, 6th nationally. On the other hand, Reading’s transport picture lags: an eco-friendly car share of 12.8% ranks 50th, and 187.5 chargers per 100,000 residents places it 21st — respectable, but not enough to shift the dial for a city with this much commuter traffic passing through it.
9. Bristol
The UK’s first European Green Capital ranks ninth, and green space is where it shines. Bristol residents live a median 293 metres from the nearest park or public garden, the 6th-shortest distance nationally, and the city emits 2.53 tonnes of CO2 per resident (14th-lowest) with 56.7% of its workforce in low-emission industries.
Bristol’s clean air zone and long-running climate commitments are visible in those figures. What isn’t visible is charging infrastructure: at 83.5 public chargers per 100,000 residents, Bristol ranks 74th out of 94, and its eco-friendly car share of 11.1% ranks 76th. For a city with this much environmental credibility, the EV transition is the conspicuous gap — and, notably, its eastern suburbs score better on both counts (see Kingswood and Fishponds below).
10. Cardiff
The Welsh capital rounds out the top 10 on the back of the same policy framework that lifted Swansea. Cardiff recycles 64.1% of household waste, the 3rd-best rate in the UK, and combines it with 58.2% of the local workforce being concentrated in low-emission industries — 7th nationally.
Access to green space is another strength, with a median 364 metres to the nearest park, a figure that owes a great deal to Bute Park and the chain of open space running along the Taff. Cardiff’s weak spot is carbon: 3.39 tonnes per resident ranks 72nd, the lowest placement of any top-10 city on the study’s most heavily weighted metric.
11. Stockport
The highest-placed city in the North of England arrives with the study’s most striking transport statistic. Stockport’s eco-friendly car share is 49.3% — second only to Peterborough — meaning roughly half of the cars registered in the borough are hybrid, plug-in hybrid, fully electric or range-extended vehicles.
Recycling is strong too, at 49.3% of household waste (9th nationally). What Stockport lacks is public charging: 114.8 chargers per 100,000 residents ranks 50th, an awkward mismatch with the local vehicle fleet. As Greater Manchester’s Bee Network expands and the borough continues to draw movers priced out of central Manchester, that gap is the one to watch.
12. Cheltenham
Cheltenham is the second Gloucestershire-adjacent entry in the top 15 and it follows the Exeter template: no single category win, no serious weakness. The Regency spa town records 2.56 tonnes of CO2 per resident (17th-lowest), 62.5 solar installations per 1,000 households (21st) and 239 public chargers per 100,000 residents (13th).
Add air quality of 6.48 µg/m³ and a workforce that is 50.9% concentrated in low-emission industries, and you get a town punching well above its 121,452 residents. Cheltenham’s soft spot is waste, with a household recycling rate of 34.7% ranking 52nd — the kind of figure that a change in collection scheme could move quickly.
13. Bournemouth
Bournemouth’s south-coast sunshine turns up in the data. The city records 60.6 solar installations per 1,000 households alongside the 13th-cleanest air in the study and 2.62 tonnes of CO2 per resident.
Waste performance is the standout, though: at 53.9%, Bournemouth has the 4th-highest household recycling rate in the UK and the best of any English city in the study. The trade-off is vehicle mix, where an eco-friendly car share of 10.4% ranks 86th, and a workforce only 42.9% concentrated in low-emission industries reflects an economy leaning more towards hospitality and tourism than knowledge work.
14. Ipswich
Ipswich posts the 5th-lowest carbon footprint in the country at 2.24 tonnes per resident, and it does so while sitting at the centre of the East Anglian offshore wind supply chain — a useful reminder that hosting energy infrastructure and emitting little are not mutually exclusive.
The Suffolk town also delivers 94.8% full-fibre coverage (joint 6th with Reading) and 253.1 public chargers per 100,000 residents (9th). Its problem is uptake rather than provision: an eco-friendly car share of 9.9% ranks 90th out of 94, one of the widest gaps between charging supply and vehicle demand anywhere in the study.
15. Weston-super-Mare
Last, but not least, Weston-super-Mare closes out the top 15 with the second-highest solar uptake in the UK: 128 installations per 1,000 households, behind only Peterborough. The North Somerset town pairs that with a 51.2% household recycling rate (7th nationally) and the 11th-cleanest air nationally.
Its weakness is a familiar one for low-density coastal towns. Residents live a median 826 metres from the nearest park or public garden, ranking 91st of 94 — a function of a sprawling built form where formal green space is concentrated along the seafront rather than distributed through residential streets.
Next in Green: The Cities Setting the Bar for the Next Ranking
Several cities landed just outside the top 15 with results worth flagging. Peterborough (#16) leads the entire study on two separate metrics — 135.6 solar installations per 1,000 households and an eco-friendly car share of 49.8% — but is held back by 3.67 tonnes of CO2 per resident, an 86th-place finish that cost it roughly the margin it needed.
Hemel Hempstead (#17) tops the country for low-emission employment at 65.2%, while Luton (#18) records the 2nd-lowest carbon footprint in the UK at 2.12 tonnes per resident. Worthing (#21), meanwhile, holds the lowest figure of all at 2.10 tonnes. Kingswood and Fishponds (#19) makes a strong case for east Bristol, with 77.1 solar installations per 1,000 households and a 33.7% eco-friendly car share — both well ahead of Bristol proper.
As for the capital, London ranks 28th with 51.55 points. The figures behind that placement are less middling than they look: Londoners live a median 292 metres from the nearest park — the 5th-shortest distance nationally — 62.2% of the workforce is in low-emission industries, and the city records 340 public chargers per 100,000 residents. What drags the total down is a combination of air quality and comparatively low solar uptake, which is what happens when you measure a city of 9.1 million against towns a fiftieth of its size.
Methodology
CoworkingCafe analysed 94 UK urban areas, scoring each across nine sustainability indicators for a maximum of 100 points. Only areas with complete datasets across all nine indicators were included; those missing data for any metric were excluded from the ranking. Scores were calculated by comparing values across all included areas, with the extreme values setting the upper and lower bounds for each metric.
Scoring overview:
- CO2 emissions per capita (20 points) — Local authority territorial CO2 emissions within the scope of influence of local authorities, subset dataset (excludes large industrial sites, railways, motorways, land use, livestock and soils). Scored inversely: lower emissions score higher. [GOV.UK, 2024]
- Air quality (15 points) — Population-weighted PM2.5 concentration: the average level of fine particulate matter (particles small enough to reach deep into the lungs and bloodstream), weighted by where people actually live and measured in micrograms per cubic metre (µg/m³). Scored inversely. [DEFRA, 2024]
- Low-emission employment share (15 points) — Percentage of full-time equivalent employees working in the ten lowest-emission industries, classified by the ONS using UK-wide residence-based emissions and excluding household emissions. Scored directly. [ONS, 2024]
