With skyrocketing gas 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 to 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 positively or negatively.
A Greenhouse Gas (GSG) is any gas that, when released into the atmosphere, traps infrared radiation (heat) and causes slow global warming. 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 down the car before turning on the air conditioning. Shades also help reduce heat and sun damage. The use of air conditioning increases fuel consumption and involves the use of fluids that are potentially harmful to the environment.
Avoid driving during rush hours. Starting and stopping driving increases emissions of pollutants that form smog.
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 stop as long as possible and avoid brake wear.
Obey the speed limit. Driving 65 mph instead of 55 mph will reduce your fuel economy by nearly 10 percent and increase exhaust pollution production.
Instead of taking separate trips, combine them as much as possible. An engine that is already warm generates 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 commute. Combining several short trips into one can make a big difference when it comes to green driving.
Use your tire gauge! Properly inflated tires are a must. Fuel economy decreases about two percent for every three pounds below recommended pressure. Check air pressure regularly; especially before embarking 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 turns off. Spilled gasoline is carcinogenic to breathe, evaporates into the atmosphere, and can seep into the ground, contaminate water, and poison wildlife.
Save fuel and reduce pollution by biking 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!
