Myth #1: Electric vehicles are worse for the climate than gasoline cars because of the power plant emissions.
FACT: Electric vehicles typically have a smaller carbon footprint than gasoline cars, even when accounting for the electricity used for charging.
Electric vehicles (EVs) have no tailpipe emissions. Generating the electricity used to charge EVs, however, may create carbon pollution. The amount varies widely based on how local power is generated, e.g., using coal or natural gas, which emit carbon pollution, versus renewable resources like wind or solar, which do not. Even accounting for these electricity emissions, research shows that an EV is typically responsible for lower levels of greenhouse gases (GHGs) than an average new gasoline car. To the extent that more renewable energy sources like wind and solar are used to generate electricity, the total GHGs associated with EVs could be even lower. Learn more about electricity production in your area.
EPA and DOE’s Beyond Tailpipe Emissions Calculator can help you estimate the greenhouse gas emissions associated with charging and driving an EV or a plug-in hybrid electric vehicle (PHEV) where you live. You can select an EV or PHEV model and type in your zip code to see the CO2 emissions and how they stack up against those associated with a gasoline car.
Myth #5: Electric vehicles are worse for the climate than gasoline cars because of battery manufacturing.
FACT: The greenhouse gas emissions associated with an electric vehicle over its lifetime are typically lower than those from an average gasoline-powered vehicle, even when accounting for manufacturing.
Some studies have shown that making a typical electric vehicle (EV) can create more carbon pollution than making a gasoline car. This is because of the additional energy required to manufacture an EV’s battery. Still, over the lifetime of the vehicle, total greenhouse gas (GHG) emissions associated with manufacturing, charging, and driving an EV are typically lower than the total GHGs associated with a gasoline car. That’s because EVs have zero tailpipe emissions and are typically responsible for significantly fewer GHGs during operation (see Myth 1 above).
For example, researchers at Argonne National Laboratory estimated emissions for both a gasoline car and an EV with a 300-mile electric range. In their estimates, while GHGs from EV manufacturing are higher (shown in blue below), total GHGs for the EV are still lower than those for the gasoline car.
