1. LOWER EMISSIONSThe main way to help the environment is to reduce your CO2 emissions. The lower the figure, the cheaper the road tax, too. 2. FUEL CONSUMPTION Thirsty cars are less eco-friendly and can be costly to re-fuel. Find out how green your car is with our facts and figures section. 3. GO HYBRID Don't be put off by the jargon. Modern hybrids, such as Toyota Prius and Honda Civic, combine petrol and electric power for greener motoring. Our handy car glossary explains how hybrid technology works. 4. SHARE CARSSharing a lift to work with neighbours, friends and colleagues is an excellent way to save money and cut your CO2. 5. WATCH YOUR WEIGHT Try to avoid lugging heavy loads whenever possible. Your car will use less fuel the lighter it is - only fill the boot when necessary. 6. FULL TANKDon't fill up your car at the petrol station if you only do short distance driving. A full tank is heavy and increases fuel consumption. 7. TYRE PRESSUREUnder inflated tyres increase fuel bills as the resistance between the tyres and the road is greater. They can be dangerous, too. |
