There are people among the environmental movement who will flat-out forswear ever driving a car because of the cost to the planet. It can admittedly be taxing on the environment to run a car, be it because of the fumes that are passed through the exhaust or the toll taken on the planet to build and fuel the car.
Most environmentalists will, however, reach some sort of compromise which entails driving a car that is more green than others. The first thing to look for in this respect is fuel economy. A car which gives you more miles per gallon of fuel will be more friendly to the environment, as the use of fossil fuels takes a toll on the planet.
In this light, it may be worth looking at some of the hybrid or alternative-fuel vehicles on the market. As the environmental movement grows in size and strength, these cars are becoming more prominent and choice is becoming greater. Some interesting new developments are taking place in the alternative fuels market, and these may make it more economical and more “green” to drive.
Sometimes, the deal with automobiles and the environment is not so much what you drive as how often you drive it. If you don’t need to drive and the weather is good, walking can be pretty good fun anyway. Obviously, this is hardly going to win around the most hardened enviroskeptic, but when you realise that the trade-off is “fewer journeys = better performance” it’s something to hold on to.
