Eco-Friendly Driving: Your Essential Guide

Every journey you make has an environmental impact, whether that’s a daily commute, running errands, or a full-blown road trip across the UK. It’s natural, therefore, to want to reduce that environmental impact as much as possible. But many drivers can’t afford to go green straight away. Luckily, going green doesn’t have to mean going electric overnight. 

There are plenty of practical steps you can take to reduce your car's carbon footprint, and many of them are simpler than you might think. Here are our top tips to help you drive smarter, cleaner, and more sustainably.

1. Keep tyres properly inflated

Maintaining the correct tyre pressure is one of the easiest and most effective ways to improve your vehicle’s fuel efficiency. That’s because under-inflated tyres create more rolling resistance, which means your engine has to work harder and burn more fuel. This not only increases emissions but also wears your tyres out faster. 

According to recent studies from Michelin, tyres under-inflated by just 15psi can use up to 6% more fuel. Now, 6% may not seem like a great deal more, but it really adds up over time, both in terms of money and carbon emissions. 

It’s crucial, therefore, to check your tyre pressure at least once a month and before long journeys. You can find the recommended pressure in your vehicle’s manual or inside the driver-side door frame.

2. Reduce idling time

Idling burns fuel unnecessarily and contributes significantly to air pollution, especially in denser towns and cities. If you're waiting for someone or stuck in traffic for more than a minute or two, it’s better to switch off your engine (whenever it’s safe to do so). 

Turning off your engine instead of idling can reduce fuel consumption by as much as 10% over time. Plus, it helps improve local air quality, which is especially important in busy urban areas or near schools. 

In fact, many modern cars have stop-start technology built in. But if yours doesn’t, a simple change in habit can go a long way. Not only will you reduce emissions, but you’ll also save on fuel costs. Just be sure to keep in mind the drain on your car’s battery if your car doesn’t have stop-start technology.

3. Lighten the load

It’s easy to forget what's in your boot or back seat, but every extra kilogram adds to your car’s workload. Removing unnecessary items (especially heavy ones like golf clubs, toolboxes, or that bag of compost you’ve been meaning to drop off for weeks) can dramatically improve fuel efficiency. 

Similarly, remove roof boxes and racks when not in use. They create additional drag, which means your engine has to work harder and consume more fuel to get and stay up to speed. 

Even carrying an extra 50kg can increase fuel consumption by 1–2%, so it really is worth keeping your car clean and clutter-free.

4. Keep up with regular servicing

A well-maintained vehicle runs more efficiently and produces fewer emissions because, when everything’s working smoothly, your engine doesn’t have to work as hard to maintain performance. Regular servicing helps ensure that essential components – such as the air filter, spark plugs, and engine oil – are always kept in top condition. 

Dirty air filters can reduce fuel economy by up to 10%, and worn spark plugs can cause misfires, reducing efficiency and increasing harmful emissions. That’s why keeping up with your service schedule is key.

5. Drive smoothly

Aggressive driving, like rapid acceleration, harsh braking, and speeding, increases fuel consumption and emissions more than you might think. Instead, aim for smoother driving habits, such as:

Accelerating gradually

There’s a window of optimal acceleration in order to minimise fuel usage. Accelerating too quickly usually puts too much fuel into the engine for it to burn properly – leading to wasted fuel. Conversely, accelerating too slowly means you spend too much time in lower gears; and these tend to require more fuel per revolution in order to maintain torque.

Anticipating traffic flow

Keeping your eye far ahead of traffic and anticipating traffic flow means that you don’t always have to brake to a stop (which then requires you to use a lot of fuel to get going again). Instead, you’ll be able to slow gradually and, occasionally, be able to avoid stopping altogether if, for example, the traffic lights turn back to green in time.

Sticking to speed limits

With the exception of many country lanes, speed limits are usually set in order to account for a safe driving speed on the conditions of that road. So a 40mph road is likely set as such because of a number of bends, hidden turnings, pedestrian areas, and other hazards. 

Speeding in these areas, therefore, dramatically increases the chance of you having to suddenly brake. And while we mentioned that driving in lower gears uses more fuel, driving too fast also increases fuel consumption through dramatically increased air resistance. In fact, the difference in fuel consumption between driving at 70mph and 80mph can be as much as 25%.

Using cruise control on motorways can also help maintain a consistent speed and reduce fuel use. An added benefit here is that not only will it reduce wear and tear on your vehicle, but it will also make your journeys more relaxed and enjoyable – just remember to stay alert! 

In fact, according to the Energy Saving Trust, smoother driving can reduce fuel consumption by up to 15%, which is a big win for both your wallet and the environment.

6. Combine journeys

Cold starts use more fuel and emit more pollutants than a warm engine. Where possible, combine errands into one trip rather than making multiple short journeys. This has the two main benefits of reducing your emissions while also being more time-efficient. 

Planning your route ahead, such as by using apps to avoid traffic hotspots, can also cut down idle time and fuel use.

7. Consider car sharing

Another way to reduce emissions through forward planning is to car share. This is the ultimate in fuel saving. 

Perhaps you can use a spare seat in one of your colleagues’ cars to make the journey to and from work, or you could offer to drive others to save them having to use their vehicles. This cuts the number of cars on the roads, and if everyone chips in some petrol money, it makes journeys cheaper for everyone too.

8. Consider using eco-friendly fuel options

If you're not ready to switch to an electric vehicle just yet, consider using eco-friendly fuels like E10 petrol, which has a higher ethanol content and produces fewer CO2 emissions. Luckily, this has now become pretty much standard around the UK. 

For diesel vehicles, using high-quality fuel additives can help reduce soot buildup and improve combustion efficiency. Make sure you're using the right oil too; low-viscosity, synthetic oils can improve fuel economy and reduce emissions compared to conventional oils.

9. Keep your air con in check

Air conditioning can increase fuel consumption, especially at low speeds. On cooler days, consider opening a window instead (though at motorway speeds, open windows can cause drag). 

It’s also worth having your air conditioning system serviced regularly – an efficient system works better and uses less energy. Don’t forget: if your air con smells musty or isn’t cooling as it used to, it might be time for a full service.

10. Upgrade when you're ready

While our tips help reduce your environmental impact in the short term, switching to a hybrid or electric vehicle is the ultimate step toward low-emission driving. When you're ready, Kwik Fit is here to help you maintain your EV just as efficiently.
