Electric vehicles are a technology that has rapidly become widespread in recent years. At first glance, they are thought to have less impact on the environment than gasoline-powered vehicles, but the truth about electric vehicle emissions is more complex. Criticized for producing more emissions during the production process, electric vehicles quickly make up for this difference during use.
Emission impact of electric vehicle production
The production of electric vehicles produces more emissions than gasoline vehicles, mainly due to the manufacturing process of their batteries. According to the 2023 Polestar and Rivian Pathway Report, the production of an average electric vehicle produces 14 tons of carbon dioxide equivalent emissions, compared to 10 tons for gasoline vehicles. This difference shows that electric vehicles produce 40% more emissions during the production phase.
However, this could change with the development of battery technologies and reduced reliance on rare earth elements. Argonne National Laboratory’s GREET model shows that electric vehicle production produces 80% more greenhouse gases than gasoline vehicles. This means that when they roll off the production line, electric vehicles start with a higher “carbon debt” than gasoline vehicles.
The advantages of electric vehicles over gasoline vehicles
Fortunately, electric vehicles quickly offset this carbon debt. It usually takes less than two years for an electric vehicle to reach emissions parity with a gasoline vehicle, although this depends on the energy source used.
For example, even on the NYLI eGrid, one of the dirtiest energy grids in the US, it takes only 1.9 years for electric vehicles to reach emissions parity. On the CAMX eGrid, one of the cleanest grids, it takes just 1.4 years.
Many people charge their electric vehicles entirely with clean energy at home with solar panels and home batteries. This allows electric vehicles to make up the emissions difference much faster.
Environmental and health impacts
Rare earth elements used in the production of electric vehicles can cause environmental and health problems. The mining of these elements can cause health problems such as eye and skin irritation and has been linked to human rights violations. However, new technologies are being developed that reduce the reliance on rare earths in batteries.
Battery recycling programs not only reduce emissions associated with electric vehicle production, but also enable the reuse of rare earths. These developments are further reducing the environmental impact of electric vehicles.
Although more emissions are produced in the production of electric vehicles, they quickly make up the difference over their lifetime. On average, an electric vehicle used for 15 years produces 30 grams of carbon dioxide emissions per kilometer, while gasoline vehicles produce 80 grams.
It is clear that electric vehicle emissions are much lower than gasoline vehicles and are a better option for the environment. Criticism about the environmental impact of electric vehicles is largely based on misunderstandings when evaluated in the light of these facts.
