Greenhouse Gas Emissions from a Typical Passenger Vehicle
WEBAug 23, 2024 · 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. Electric vehicles (EVs) also emit a small amount of GHGs due to air conditioner/HFC leakage.
