All fuel-powered cars produce emissions directly from their exhausts.
Reducing those emissions can help improve air quality and lessen your impact on the climate. Here are our 10 favourite low-emission cars – all available to buy as nearly new and used cars from Motorpoint.
Every car on this list can be driven in any UK city that has a clean-air zone (CAZ) free of charge. Plus, they can all enter London's ULEZ area without payment.
BMW 1 Series – 121g/km CO2

The BMW 1 Series is the smallest car the brand makes. Thanks to sharing hardware with Mini models, it has all the handling and performance you'd expect from a car with a BMW badge. The most recent version might've ditched the low-CO2 diesel engines if its predecessor, but its punchy petrol engine only emits 121g/km. Not only is the 120 model fairly quick, completing the 0-62mph sprint in less than eight seconds, but it's refined too, so you'll barely hear a peep if you're just cruising around.

Ford Focus Estate – 93g/km CO2

Many family cars have abandoned diesel power altogether, but you can still find the excellent Ford Focus Estate equipped with the penny-pinching 1.5-litre EcoBlue diesel. This 120hp unit won't win any drag races but has enough power to propel you, your passengers and your cargo up to motorway speeds without a fuss. Avoid the far end of the accelerator pedal and you'll see sky-high mpg figures and CO2 emissions of less than 100g/km of CO2.

Audi A4 – 106g/km CO2

The Audi A4 walks a thin line somewhere between the slightly softer Mercedes C-Class and the firmer but sportier BMW 3 Series. For you, that might make it the best of both worlds with accurate, predictable handling and impressive compliance over bumps. This reassuring setup makes the A4 an epic long-distance cruiser, especially when equipped with the 2.0-litre diesel engine you'll find in 35 TDI versions, which can cover hundreds of miles on barely any fuel with even fewer emissions.

Volkswagen Golf – 99g/km CO2

The latest Volkswagen Golf aims to prove less is more – there are fewer controls in the cabin, a more focused engine lineup and even less emissions out the exhaust pipe. Golfs equipped with the entry-level 2.0-litre diesel engine emit less than 100g/km of CO2 while averaging more than 65mpg if you drive with a light right foot. Those numbers mean you can rack up huge miles in your Golf on a very small budget – a job that's made easier by its comfy ride quality and rich suite of on-board tech to keep you entertained.

Lexus UX – 97g/km CO2

With so many talented rivals in the compact premium SUV segment, the Lexus UX sometimes gets overlooked. That's a shame because the UX250h benefits from parent company Toyota's years of experience building hybrid cars. You get smooth, silent and snappy reactions from the hybrid powertrain, allowing you to cut through gaps in traffic, while keeping your running costs low thanks to only using the engine when it's needed. Inside, the UX's hewn-from-granite build quality stands out with excellent materials and a busy-but-intuitive dashboard.

Renault Captur – 103g/km CO2

Even entry-level versions of the Renault Captur are impressively efficient, so you don't need to step up to one of the electrified versions to clean up your act. Nevertheless, you should still consider Renault's E-Tech Hybrid 145 engine thanks to its excellent efficiency, zippy off-the-line performance and tiny carbon footprint. This second-generation Captur is substantially improved compared to the car it replaces, too. There's good passenger space, aided by sliding rear seats, and a neat dashboard all focused around a slick, easy-to-use touchscreen.

Skoda Kamiq – 116g/km CO2

By almost any measure, the Skoda Kamiq is an excellent car. It's easy to drive, comfortable over the UK's broken Tarmac, and almost impossibly practical for its size. There are acres of passenger space, allowing even tall adults in the back to stretch out, and a handy, square boot that will swallow suitcases or pushchairs without complaint. Most engine options for the Kamiq are efficient, but we think the entry-level 95hp 1.0-litre TSI petrol is the one to go for – there's enough power for relaxed day-to-day driving while keeping your emissions output in check.

Suzuki Vitara – 104g/km CO2

Considering the Suzuki Vitara's well-earned reputation for off-roading, you might not expect this chunky family car to be much of a tree hugger. However, recent models have paired the company's 1.4-litre Boosterjet turbo petrol engine with a 48V mild-hybrid system. This setup can't power the wheels directly using the hybrid motor but it can recapture wasted energy from slowing down or braking, helping slash the Vitara's carbon emissions and bump up its fuel efficiency.

Toyota Yaris – 92g/km CO2

With such an illustrious history building hybrid cars, many Toyota models could've taken this spot. We've chosen the Toyota Yaris, however, because it squeezes all the company's clever electrified technology into a tiny city-friendly hatchback. Equipped with the 1.5-litre hybrid engine, the Yaris is smooth and easy to drive thanks to the responsive electric motor and fuss-free standard automatic gearbox. The most recent model injects a dose of style into the mix too, with a neat, well-made cabin inside and curvy, eye-catching styling on the outside.

Volkswagen T-Roc – 111g/km CO2

Family buyers would've flocked to the Golf in the past, they're now more likely to look at the Volkswagen T-Roc compact SUV. They'll have little to complain about too, because the T-Roc has all the reassuring build quality and on-board technology you'd expect from a VW in a desirable small SUV package. Most of the T-Roc's smaller engines have low exhaust emissions but the 2.0-litre TDI diesel engine would be our pick. This unit has enough grunt for motorway driving but a tiny appetite for fuel so you can go many miles between refills.
