![]() Tailpipe emissions for a PHEV operating on both electricity and gasoline cannot be calculated without detailed information about how the specific PHEV operates. When a PHEV is operating on gasoline only, it creates tailpipe emissions based on its gasoline fuel economy. When operating on electricity only, a PHEV does not generate any tailpipe emissions. Calculating tailpipe emissions for PHEVs is more complicated because they use both gasoline and electricity as fuel sources.A fuel cell electric vehicle (FCEV) operating on hydrogen will emit only water vapor. Electric vehicles (EVs) have a battery instead of a gasoline tank, and an electric motor instead of an internal combustion engine.Electric vehicles (EVs) also emit a small amount of GHGs due to air conditioner/HFC leakage. For gasoline vehicles, the emissions of HFCs are small in comparison to CO 2 however, the impact of these emissions can be important because they have a higher global warming potential (GWP) than CO 2. In addition to carbon dioxide (CO 2), automobiles using gasoline produce methane (CH 4) and nitrous oxide (N 2O) from the tailpipe and all vehicles can emit hydrofluorocarbon (HFC) from leaking air conditioners.Every gallon of gasoline burned creates about 8,887 grams of CO 2. This assumes the average gasoline vehicle on the road today has a fuel economy of about 22.2 miles per gallon and drives around 11,500 miles per year.A typical passenger vehicle emits about 4.6 metric tons of CO 2 per year.The average passenger vehicle emits about 400 grams of CO 2 per mile.Visit for more details, including the calculations. The hydrogen combines with oxygen to form water (H 2O), and carbon combines with oxygen to form carbon dioxide (CO 2). When gasoline burns, the carbon and hydrogen separate. Most of the weight of the CO 2 doesn't come from the gasoline itself, but the oxygen in the air. How can burning one gallon of gasoline produce 8,887 grams (approximately 20 pounds) of tailpipe carbon, when one gallon of gasoline weighs only about six pounds? CO 2 emissions from a gallon of diesel: 10,180 grams CO 2/ gallon.CO 2 emissions from a gallon of gasoline: 8,887 grams CO 2/ gallon.How can I find and compare carbon dioxide (CO 2) emission rates for specific vehicle models?.How does EPA measure carbon dioxide (CO 2) emissions from vehicles?.Are there any greenhouse gas (GHG) emissions associated with the use of my vehicle other than what comes out of the tailpipe?.What are the tailpipe emissions from a plug-in hybrid electric vehicle (PHEV) or an electric vehicle (EV)? What about hydrogen fuel cell vehicles?.Are there other sources of greenhouse gas (GHG) emissions from a vehicle?. ![]() What is the average annual carbon dioxide (CO 2) emissions of a typical passenger vehicle?.How much tailpipe carbon dioxide (CO 2) is emitted from driving one mile?.How much tailpipe carbon dioxide (CO 2) is created from burning one gallon of fuel?.Tailpipe Greenhouse Gas Emissions From a Typical Passenger Vehicle (pdf) (118.99 KB, June 2023, EPA-420-F-23-014)
