These are averages. Individual vehicles may differ in miles traveled and pollution emitted per mile than indicated here. Emission factors and pollution/fuel consumption totals may differ slightly from original sources due to rounding. 2. The emission factors used here come from standard EPA emission models. They assume an "average," properly maintained car on the road in 1998, operating on typical gasoline on a summer day (72-96°F). Emissions may be higher in very hot or very cold weather. 3.
