  4. United States vehicle emission standards - Wikipedia

    en.wikipedia.org/wiki/United_States_vehicle...

    The amount of carbon dioxide emitted per liter or gallon burned varies by fuel type, since each type of fuel contains a different amount of carbon per gallon or liter. The ratings reflect carbon dioxide (CO 2), nitrous oxide (N 2 O) and methane (CH 4) emissions, weighted to reflect each gas's relative contribution to the greenhouse effect.
