Know the Greenhouse Gas Rating

If you are looking to reduce your carbon footprint and save money, then buying a car with a higher Greenhouse Gas Rating is a sure way to do this.

U.S. EPA Fuel Economy and Environment Label

Starting in 2013, all new cars are required to display the updated Fuel Economy and Environment Label (Label). The Federal label provides helpful ways to compare vehicles, such as:

  • New ways to compare energy use and cost between new-technology cars that use electricity and conventional cars that are gasoline-powered.
  • Useful estimates on how much consumers will save or spend on fuel over the next five years compared to the average new vehicle.
  • Easy-to-read ratings of how a model compares to all others for smog emissions and emissions of pollution that contribute to climate change.
  • An estimate of how much fuel or electricity it takes to drive 100 miles.
  • Information on the driving range and charging time of a plug-in vehicle.
  • A QR Code that will allow users of smartphones to access online information about how various models compare on fuel economy and other environmental and energy factors.

Global Warming

Greenhouse gases (ghg) trap heat in the atmosphere, thereby creating a greenhouse effect known as global warming. Some greenhouse gases occur naturally and are emitted in the atmosphere through natural processes and human activities. Other greenhouse gases are created only through human activities. Scientists are certain that human activities are changing the composition of the atmosphere and that increasing the concentration of greenhouse gases will eventually change the planet's climate.

Greenhouse Gases

Greenhouse gases (ghg) emitted from vehicles include Carbon Dioxide (CO2), Methane (CH4), Nitrous Oxide (NO2), and Hydroflurocarbons (HFCs) from air conditioner refrigerant.

Scale for the Greenhouse Gas Rating

The table below shows the CO2 emission levels for each Greenhouse Gas Rating.

10 0-200
9 201-243
8 244-291
7 292-335
6 336-378
5 379-456
4 457-539
3 540-613
