EPA's greenhouse gas score [28] reflects the amount of greenhouse gases a vehicle will produce over its lifetime, based on typical consumer usage.

A typical passenger vehicle emits approximately 4.6 metric tons of carbon dioxide per year, according to estimates from the U.S. Environmental Protection Agency (EPA).
Points are earned if the vehicle's greenhouse gas emission levels are at least 50% below the U.S. average for 2000-2009 (.274 kg per passenger mile). Minimum qualifications for vehicles must be greater than or equal to an average of 148 passenger miles per gallon. Higher levels of efficiency earn greater points. [8]
