Fossil fuels produce NO2, which is linked to asthma attacks, bronchitis, and higher risks of heart disease and stroke, [1]according the EV news site Electrek . But the nonprofit news site Grist.org notes a new analysis showing that those emissions [2]decreased by 1.1% for every increase of 200 electric vehicles — across nearly 1,700 ZIP codes.
> "A pretty small addition of cars at the ZIP code level led to a decline in air pollution," said Sandrah Eckel, a public health professor at the University of Southern California's Keck School of Medicine and lead author of the study. "It's remarkable."
The study was done at the University of Southern California's medical school, by researchers using high-resolution satellite data, [3]reports Electrek :
> The [4]study, just published in The Lancet Planetary Health and partly funded by the National Institutes of Health, adds rare real-world evidence to a claim that's often taken for granted — that EVs don't just cut carbon over time, they also improve local air quality right now... The researchers ran multiple checks to make sure the trend wasn't driven by unrelated factors. They accounted for pandemic-era changes by excluding 2020 in some analyses and controlling for gas prices and work-from-home patterns. They also saw the expected counterexample: neighborhoods that added more gas-powered vehicles experienced increases in pollution. The findings were then replicated using updated ground-level air monitoring data dating back to 2012...
>
> Next, the researchers plan to compare EV adoption with asthma-related emergency room visits and hospitalizations. If those trends line up, it could provide some of the clearest evidence yet of what we already know: that electrifying transportation doesn't just clean the air on paper; it improves public health in practice.

Americans should be able to buy the car they want.
Affordable vehicle ownership is essential to the American Dream and a primary driver of economic mobility out of poverty in the United States. Americans rely on vehicles to reach jobs, education, health care, and essential services. This is especially true in rural areas and regions without robust public transit.
We should be improving affordability and expanding consumer choice and ultimately advancing the American Dream by making it easier to reach jobs, gr
Even better: no cars at all (Score:2)
We need to eliminate car dependency and give people a choice of transportation. Freedom of mobility includes freedom to not travel by automobile. Side benefits include less pollution.
