BBC Environment – Proponents of a motoring technique known as “eco-driving” — who include the AA, the Energy Saving Trust and the government — claim that it will not just cut emissions of carbon dioxide, but could also improve fuel efficiency by up to 30%.
The idea is that through good maintenance, a more relaxed driving style and cutting out short trips, you can make a difference to the health of the planet – and your wallet.
First rule of eco-driving – ditch unnecessary weight. The suitcase,
beach bag, cool bag and picnic rug are weekend essentials. But I chuck
out old car park tickets and receipts, and recycle the accumulated
water bottles and drink cans.
Next I make sure the tyres are inflated to the correct
pressure. Under-inflated tyres are not just dangerous – they create
more resistance to the road and so make the car less efficient.
Stopping at a supermarket to get fuel, I obey another
eco-driving edict – not to brim the tank, as this adds extra weight and
reduces fuel efficiency. I pump in 35 litres (the tank holds 40).
£41.26 – painful, but not as bad as before. …
The central tenet of eco-driving is to get into the higher gears sooner and not to rev the engine too hard. At 2,500 revs a minute, I change up. And again. And again. So far so good. The road is relatively quiet, there are no speed bumps and few traffic lights.
An eco-driver has to read the road – if you can plan ahead, you won’t be accelerating and braking so much, thereby saving fuel and CO2 emissions. Sadly I am a bit poor at this aspect, and miss my turning. Doubling back wastes fuel, pumps out more greenhouse gases, and earns me some wifely derision.
For as long as I have driven, I’ve used the gears to slow down. But with eco-driving, the idea is to lift off the gas in a higher gear, and allow the car to lose momentum. If you’re a good eco-driver, you’ll then select the right gear to smoothly move on, without coming to a halt and having to bury your right foot in the carpet to get going. Soon, we’re cruising along the A3 at a stately 60mph – 10 miles per hour under the speed limit is good for the environment and more miserly on fuel. (08/11/08)
