Driving an EV in the U.S. is Now One-Third Cleaner Than Gasoline Cars

Original Article by Andrei Nedelea

Recent studies reveal that driving an electric vehicle (EV) in the U.S. is significantly cleaner than driving a gasoline car, with regional variations impacting the overall emissions. A new analysis from the Union of Concerned Scientists (UCS) shows that EVs now produce fewer emissions in 93% of the U.S., a dramatic increase from just 45% a decade ago.

Key Findings

The UCS study compared the emissions of EVs to those of highly efficient gasoline cars, setting a new benchmark of 57 mpg for the comparison. Remarkably, they found that driving the most efficient EV in the U.S. generates less global warming emissions than any available gasoline-only vehicle, including hybrids.

Regional Differences

Electricity generation methods vary across the country, affecting the environmental impact of EVs. For instance, driving an EV in upstate New York, which boasts the cleanest electricity production in the U.S., is equivalent to driving a gasoline car with an efficiency of 219 mpg. Even in Texas, where over 60% of electricity comes from fossil fuels, an EV is comparable to a gasoline car achieving 82 mpg.

Nationwide Impact

On average, the emissions from driving an EV across the U.S. equate to driving a gasoline car with an efficiency of 94 mpg. This average could improve further with the introduction of more efficient and affordable EV models, which are currently lacking in the market.

Efficiency Comparisons

The UCS also evaluated the lifetime emissions of EVs compared to gasoline vehicles. They found that an average EV produces 52% lower emissions over its lifetime than a gasoline sedan with a combined efficiency of 32 mpg. For pickups, the reduction is even more significant, with EVs producing 57% lower emissions than their gasoline counterparts.

Environmental Considerations

While the emissions from driving EVs are significantly lower, it's important to consider the environmental impact of the entire EV supply chain, including the extraction and processing of raw materials for batteries. Nonetheless, the shift towards cleaner electricity generation in the U.S. has played a crucial role in making EVs a more sustainable option.


The UCS study underscores the environmental benefits of driving EVs in the U.S., highlighting the need for improved charging infrastructure and the introduction of more efficient and affordable EV models.
