Do you realise you can do allot for the environment by trading in your car for a newer, more cost-effective model? Alternatively read the points below and change your driving habits, which also make a vast difference to the planet.

• Don't drive around with extra weight in your car - the engine will have to work harder so you'll use more fuel. Take everything pout you don't need.
• Remove roof boxes and racks when you’re not using them, because the extra aerodynamic drag they cause will mean fuel consumption is higher.
• Always close the windows and sunroof and get any loose items of external trim fixed, because these all create drag, which dents your car’s fuel economy.
• Always check the manufacturer’s service schedule and have any work carried out by a recommended garage - a well-looked after car emits less carbon dioxide than one that isn't.
• Check those tyres! Under-inflated tyres increase your car’s fuel consumption, so check them weekly. Also, keep an eye on your car’s fuel consumption and investigate any sudden changes. Also remember that under-inflated tyres are illegal so they must be checked regularly.
• Modern engines don't need to be warmed up before driving, so just drive off after you've started the car. That said, a car’s engine is at its most inefficient when cold, so don’t use your car for very short trips - walk or ride a bike instead. Use public transport for other trips, too.
• You may not think to do this but if you get stuck in traffic for even a couple of minutes, switch the engine off. Air-conditioning, heated seats and other electrical components also use energy, so switch off what you don't need.
• Driving in general can be more effective if you are alert. Try and keep well back from other drivers and keep moving rather than breaking, use the gears to slow the car rather than the brake etc. These factors will all help reduce fuel consumption. Also avoid having to brake suddenly and don't race between sets of traffic lights or junctions.
• Sticking to the speed limit will save fuel. Cruise control can help you to maintain a steady speed.
• Use the highest gear possible without letting the engine labour, and try changing straight from second to fourth gear or third to fifth – this saves time and fuel, and reduces clutch wear and tear.
• Don't travel in the rush hour if you can avoid it. Plan a route that misses busy areas or roadwork's and stick to roads that allow you to drive at a steady speed, rather than having to stop and start.
• Share a car with friends or colleagues, or join a car-sharing scheme such as www.liftshare.org.
• Learn to press the accelerator lightly and smoothly. Don’t over-rev the engine - keep the revs under 3000rpm and cruise along.
• Allow more time for journeys so you don’t have to rush, and stay relaxed for a smoother trip.
