The claim that electric cars are worse for the climate than gasoline cars circulates widely in news commentary and on social media. It rests on a real fact: manufacturing an electric vehicle, especially its battery, produces more emissions than manufacturing a comparable gasoline car. But life-cycle studies, which count emissions from manufacturing, fuel or electricity production, driving and disposal, consistently find that battery electric cars produce substantially lower total greenhouse gas emissions over their lifetimes in most of the world, including in countries that still rely heavily on fossil fuels for electricity. The extra manufacturing emissions are typically paid back within one to two years of normal driving. The advantage grows as electricity grids become cleaner.

The claim

Versions of the claim say that an electric car must be driven for many years before it becomes cleaner than a gasoline car, that coal-fired electricity makes electric cars dirtier, or that battery production makes them a net harm. Some pieces cite specific studies to argue that diesel cars are cleaner.

Origin

In 2017 the Swedish Environmental Research Institute (IVL) published a review of battery production emissions. Media reports widely claimed that it showed an electric car would need to be driven for eight years to break even with a gasoline car. The report's authors said their findings had been misrepresented, and in 2019 they published an update estimating much lower battery production emissions, reflecting improvements in manufacturing. A 2019 analysis by researchers associated with Germany's Ifo Institute argued that a diesel car could be cleaner than a Tesla; other researchers criticized its assumptions about battery emissions, battery life and electricity.

What the evidence shows

Manufacturing emissions are higher, but recovered. Building an electric car typically emits more than building a comparable gasoline car, mainly because of battery production. But because driving on electricity emits less than burning gasoline, this "carbon debt" is usually repaid within one to two years of typical driving.
Life-cycle studies. A 2021 analysis by the International Council on Clean Transportation estimated that battery electric cars registered that year had life-cycle emissions about 66 to 69 percent lower than comparable gasoline cars in Europe, 60 to 68 percent lower in the United States, 37 to 45 percent lower in China and 19 to 34 percent lower in India. Studies by the International Energy Agency, Argonne National Laboratory and academic groups have reached broadly similar conclusions.
Dirty grids. Even where electricity comes largely from coal, electric cars are generally comparable to or somewhat better than gasoline cars, partly because large power plants and electric motors are more efficient than car engines. As grids add renewable energy, electric cars become cleaner over their lifetimes, while gasoline cars do not.
Battery recycling. Recycling and reuse of batteries can further reduce life-cycle impacts.

Electric cars do have real environmental issues, including the impacts of mining lithium, cobalt and nickel, and they still produce particulate pollution from tires and brakes. These deserve attention, but they do not make electric cars worse for the climate overall.

Why it persists

A kernel of truth. Manufacturing emissions really are higher, which makes the claim seem credible.
Out-of-date numbers. Early estimates of battery emissions were higher than current ones.
Selective accounting. Some comparisons count battery emissions but ignore emissions from extracting, refining and transporting oil.
Culture war. Electric cars have become politically symbolic, encouraging motivated reasoning on all sides.

Lessons for readers

Compare total life-cycle emissions, not just one stage.
Check whether numbers reflect current technology and electricity mixes.
Ask whether both sides of a comparison are accounted for in the same way, including fuel production.
Real downsides, such as mining impacts, are separate from overall climate effects.
Be cautious about headlines that summarize technical reports; check what the authors actually said.
