New or Used Car - Which is Greener?


As much as you try, bicycling and public transportation just won’t cut it. Perhaps your home is far from a transit hub, or you simply live in a region where public transportation is ineffective. Bicycles are out of the question for any length of trip because your bike lanes are approximately 12 inch strips on the right side of the road (welcome to my city). Even carpooling, while beneficial for certain destinations, cannot always assist in getting groceries and other necessities. So, as green as you strive to be, there’s no way around having a car.

Do not despair! There are many options available that can help minimize your impacts. The first decision should go without saying, but with marketing messages coming from all angles, rational thought can be swayed by its influence. Most simply, buy the largest vehicle you need, yet the smallest you can manage. While that new 7-seater with half-ton pickup bed seems like a great idea for transporting landscaping supplies concurrently with the soccer team, you have to ask yourself; will the majority of this vehicle’s use be embracing its many features? If not, you can likely look to a smaller, more efficient, and cheaper mode of transportation.

Now that you have identified the class of vehicle, it’s time to decide between new versus pre-owned. Unfortunately, from an environmental standpoint, there is little agreement amongst researchers on which is the “greener” choice. While an older, inefficient vehicle is obviously less desired than a new and extremely efficient hybrid or compact car, further questions arise on the fate of the original one and energy/resources used for the construction of the new vehicle. Without delving into conjecture and independent statistics, leave it at this: If you absolutely need a car, pursue the best value for the dollar over its lifetime, including both new and used in your consideration.

Use the EPA’s Green Vehicle Guide to learn about the overall emissions and fuel usage from a variety of vehicles, including your own to use as a baseline. While you may not see a direct impact on your wallet from reduced emission levels, you are making a choice that benefits everyone, at no additional cost to yourself. As an example, an EPA SmartWay or higher rated vehicle is so clean, it would have to be driven many thousands of miles to equal the air pollution generated by running a lawn mower for one hour (Of course, this raises many valid questions about the lawn mower). In addition, residents of certain states may purchase vehicles with a Partial Zero Emission Vehicle (PZEV) rating, nearly the same standard hybrids such as the Civic and Prius are required to meet. The tailpipe emissions of these cars are often cleaner than the ambient air in your own city! Don’t take that as an endorsement to breathe through your car’s exhaust, but understand the improvements being made on vehicle emissions.

One final note: In 2008, the EPA changed their MPG reporting standards. This means that vehicles of model year 2008 or later are using the new numbers, however, 2007 and earlier models are based on a separate calculation. When shopping for used cars, it may appear that an older model achieves substantially better fuel economy than the new model, but this difference is more than likely attributed to the changed reporting. Why was this done? To confuse the consumers in an already stressful situation? No, rather, the new fuel economy standards should better reflect the normal usage of a vehicle (A/C on more often, driving at faster highway speeds, etc.). What does this all mean to you, the consumer? Finally, the numbers you see on the sticker are likely what you will see when driving. On the Green Vehicle Guide mentioned earlier, the EPA has posted adjusted MPG numbers for some older model year vehicles for appropriate comparison.

Now if only they would help decide between the hardtop and convertible...
