With skyrocketing gasoline prices being what they are, the dangers of global warming, and public concern about foreign oil, more and more automakers are offering electric, hybrid, and alternative-fuel vehicles. While buying a green vehicle is a great start in reducing the environmental impacts of driving. Of course, the vehicle you drive is the most important factor, but your driving habits and how well you maintain your vehicle will also affect the environment in positive or negative ways.
A Greenhouse Gas (GSG) is any gas that, when released into the atmosphere, traps infrared radiation (heat) and causes slow warming of the planet. The most common GHGs are: carbon dioxide (CO 2 ), methane (CH 4 ), chlorofluorocarbons (CFCs) and nitrous oxides (N 2 0). CO 2 makes up about 70 percent of total greenhouse gas emissions, which is why many vehicles produce several times their weight in greenhouse gases each year. In fact, most of the fuel you put in your gas tank turns into GHG emissions!
Let’s face it: owning a car is a necessity in today’s world, so what kinds of actions can you take to help you “drive green”?
In hot weather, park in the shade when possible and open the doors and windows to cool the car before turning on the air conditioning. Blinds also help reduce damage caused by heat and sun. The use of air conditioning increases fuel consumption and involves the use of fluids that are potentially harmful to the environment.
Avoid driving at rush hour. Starting and stopping driving increases emissions of smog-forming pollutants.
Be careful with the brakes and the accelerator. Jack-rabbit starts result in wasted fuel and release more pollutants into the environment. Let your vehicle stand still as long as possible and avoid brake wear.
Obey the speed limit. If you drive 65 mph instead of 55 mph, you’ll reduce your fuel economy by nearly 10 percent and increase exhaust pollution output.
Instead of taking separate trips, combine them as much as possible. An engine that is already warm creates much less air pollution. Catalytic converters only work well when the exhaust has heated them to a certain temperature. If you start your vehicle cold and drive just two miles, the emissions are much higher than driving an extra two miles to stop at the grocery store after your usual overnight drive. Combining several short trips into one can make a world of difference when it comes to green driving.
Use your tire gauge! Properly inflated tires are a must. Fuel economy decreases approximately two percent for every three pounds below recommended pressure. Check the air pressure regularly; especially before going on a long trip. Your tires will also last longer.
A tune-up can have a substantial impact on fuel economy. Check fluids, spark plugs and air filter. Change the oil (to be even greener ask for recycled oil) and replace worn belts. Rotate the tires and align the wheels for even tire wear.
Avoid filling the gas tank after the automatic nozzle shuts off. Spilled gasoline is carcinogenic to breathe, evaporates into the atmosphere, and can leach into the ground, contaminate water, and poison wildlife.
Save fuel and reduce pollution by riding a bike or joining a carpool or vanpool to work and carpooling to and from kids’ activities.
By following these simple tips and guidelines, you can do your part to counter global warming and help the environment. go green!
