Green Scores for Used Cars?
In addition to the model year 2016 listings, ACEEE's Greenercars.org also contains ratings for all model year 2000 through 2015 vehicles. Ratings for model year 1998 and 1999 vehicles are available in hard copy in the 1998 and 1999 editions of ACEEE's Greenercars.org, respectively. These can be purchased through the ACEEE publications office. ACEEE publications office(link is external). Ratings for older vehicles (model year 1997 and earlier) are not available. For earlier model years, fuel economy is an important determinant of greenness. So look for high-efficiency models on the federal fuel economy guide website.
How to Buy Green
Greenercars.org will help you select the vehicle that is most friendly to the planet while meeting your transportation needs. Based on official emissions and fuel-economy tests, and other specifications reported by auto manufacturers, we calculate a Green Score for each car, minivan, pickup, and SUV on the market. The Green Score falls on a scale of zero to 100. A higher score implies a greener car, meaning a vehicle having a lower environmental impact.
Green Scores and Class Rankings
In our database, vehicles can be searched by class (that is, the type or body style, such as midsize car, minivan, standard pickup, and so on). To summarize our ratings and make it easy to find the top-rated vehicles in each class, we use a five-tier class ranking—superior, above average, average, below average, and inferior—depending on where a model falls within its class. No vehicle gets a superior rating if its Green Score is worse than the overall average of all vehicles offered this model year, even if it ranks among the best in its class. Look for models that are ranked superior or above average to easily find those that have the greenest scores.
To make it easy to find the most planet-friendly new cars and trucks available this year, our highlights identifies not only the overall greenest vehicles of 2016, but also the models with the highest Green Scores in each class, "the best of 2016." the easiest way to buy green is to select a vehicle from this "best of 2016" list.
If you'd like to see more than just the models in the "best of 2016" list, use the Greenercars.org database to get details for every make and model now on the market (as well as all model year 2000 through 2015 vehicles). Our online database lists each vehicle's emission standard, fuel economy, fuel costs, health effects, carbon dioxide emissions, and overall environmental impact, along with its Green Score and class ranking. If you have identified a set of models to consider, build a comparison list in the database to comparison shop with the environment in mind.
For most consumers, the Green Score and class ranking provide a good indication of a vehicle's environmental performance. Full details on how our Green Scores are calculated are found in "Rating the Environmental Impacts of Motor Vehicles: ACEEE’s Green Book Methodology," which can be downloaded for free from ACEEE's publications site.In general, a vehicle is greener if it is cleaner (having lower pollution) or more fuel efficient (resulting in lower energy consumption and carbon dioxide emissions).
Different versions of a model have different Green Scores
Nearly all models come in different configurations, meaning different choices of engine, transmission, and other major options. A model may also be available in versions that meet different emissions standards or run on alternative fuels.
To match a model in the showroom with a listing Greenercars.org, first match its engine size and transmission type (automatic, manual, 4wd, etc.), followed by the city and highway fuel economy ratings found on the vehicle window label. Lastly, examine the window sticker or underhood ID to match the vehicle's emission standard.
