Greenhouse Gas Rating
Greenhouse gases trap heat in the lower atmosphere and create warming known as the greenhouse effect. Some greenhouse gases are emitted into the atmosphere through natural processes; however, others are created only through human activities.
Most scientists agree that human activities are changing the composition of the atmosphere and increasing the concentration of greenhouse gases, which is changing the planet's climate. Greenhouse gases emitted from vehicles include carbon dioxide (CO2), methane (CH4), nitrous oxide (NO2) and hydrofluorocarbons (HFCs).
