DAQ Explains Smog Rating Information

Fact Sheet Will Help Consumers Identify Cleaner Options

The Division of Air Quality (DAQ) is encouraging consumers to consider cleaner cars when they purchase their next vehicle. Along the Wasatch Front, vehicles contribute over half of the emissions that form PM2.5. Choosing a cleaner car can help reduce these emissions and improve air quality.

Consumers wishing to reduce their emissions should ask the following questions when purchasing a car:

DAQ has put together the following information to help consumers answer these questions.

New Cars

Look for the Smog Rating located on the right-hand-side of the EPA/DOT Fuel Economy and Environment window sticker (see Figure 1 below) to identify the cleanest vehicles. Cars with a Smog Rating of 8, 9, and 10 have the lowest tailpipe emissions and are good choices for keeping Utah's air clean. You can learn even more about a vehicle's environmental attributes by scanning the Smartphone QR Code on the window sticker with your smartphone.

Used Cars

Find the Smog Rating for used cars or cars that don't have the above window sticker by locating the Vehicle Emission Control Information sticker on the underside of the hood (see Figure 2 below). This sticker will show the vehicle's emissions standard for EPA, California, or both.

Compare this standard to Table 1 below to determine the Smog Rating. Again, Smog Ratings of 8, 9, and 10 represent the cleanest vehicles.

Alternatively, visit www.fueleconomy.gov and find the vehicle in question. Select the Energy and Environment tab to identify the vehicle's Smog Rating.

Consumers can go online to look at side-by-side comparisons of vehicles before heading to the showroom. Customers interested in finding the Smog Ratings for a range of vehicle makes and models can download the Green Vehicle Guide for the appropriate model year.

PLEASE NOTE: Some models have been certified for more than one Smog Rating.

For example, the 2013 Honda Civic is available with Smog Ratings ranging from 5 to 9 (see Figure 3 below). Those seeking to identify the cleanest vehicles should pay close attention to the 12-digit "Engine Family" or "Test Group ID" and the emissions standard certification level of the vehicle in question. This example also illustrates that many conventional, gasoline-powered vehicles are as clean as (or even cleaner than) some hybrid or alternative fuel vehicles. As indicated by the red boxes in Figure 3, the highest Smog Rating is available for all three models of the Honda Civic (natural gas, hybrid, and conventional gasoline-powered).
