![]() 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?.They’ve almost no confidence that they can use the new phone properly.Tailpipe Greenhouse Gas Emissions From a Typical Passenger Vehicle (pdf) (104 KB, June 2023, EPA-420-F-23-014) Using this special software, you can find the history of almost any building. We use almost before any and before negative words such as no, none, never, nobody, nothing. I almost wish I hadn’t offered to pay his fine. We use almost (but not nearly) to soften statements: I thought you’d taken it out of the freezer. We also use almost and nearly with extreme adjectives such as perfect, impossible or frozen: Nearly all my friends were in the photograph. Their CD has sold almost 90,000 copies in the last week. In these examples, almost and nearly can both be used: We use almost and nearly to refer to the progress of things, especially if we are measuring and counting things.
