Electric Cars Are Making It Easier To Breathe, Study Finds (thedrive.com) 165

An anonymous reader shares a report: It turns out that when fewer cars spew exhaust as they drive along, air quality improves. That's the conclusion of a new study published in The Lancet Planetary Health that looked at the effect of increased numbers of both EVs and plug-in hybrids on air pollution in California. The Golden State has by far the largest number of plug-in vehicles in the United States, and they've now reached significant numbers to have a positive impact on air quality.

Between 2019 and 2023, for every 200 EVs or plug-in hybrids added, nitrogen dioxide (NO2) levels dropped 1.1%, according to the study, which used satellite data to track those levels through the unique way NO2 absorbs and reflects sunlight. NO2 can trigger asthma attacks, cause bronchitis, and increase the risk of heart disease and stroke.

  • Not that many years agon air pollution was horrible in Beijing. Not so much anymore. Air quality is quite good I am led to believe. Electric scooters displacing dirty two strokes certainly helped a lot.

    Same story in a few other major cities in China.

    • Air quality is quite good I am led to believe.

      You were mislead. It's fucking abysmal.
      I will grant you it's not as lethal as it used to be.

        You were there this last year? Achieving a 95% reduction in air pollution over 2013 is pretty darn good and it's mostly from the government pushing EVs. Downside is the poor rural areas freeze in the winter because they can no longer get coal and the CCP doesn't care.

        • You were there this last year?

          No, but living in an area with yearly wildfires, I have experience with what different AQIs mean, and Beijing's are not a State secret (surprisingly)

          What the fuck kind of retort is, "you were there this last year?" anyway?
          Do you live in a world where nothing exists unless you go there?

          I agreed with you that Bejing's air is less lethal than it used to be. But it's regularly as bad as my air is when I'm choking through wildfire smoke.

          PM2.5 monitoring by the US Embassy in Beijing shows that PM2.5 dropped by 62% from 2013 to 2023. It actually significantly increased in 2023. There is no newer data, but 95% seems a bit far fetched.

      • "Improved but still bad" falls under "not so much anymore", I've said before that China is at best speedrunning development, it can't seem to skip steps like the "pollute everything" stage.

    Per TFA, the 1.1% decrease in NO2 levels for each 200 zero-emission vehicles (ZEVs) introduced was within a zip-code tabulation area or ZCTA. Not an introduction of 200 ZEVs for the whole state of California.

    • by AmiMoJo ( 196126 )

      How big is a ZCTA?

      Either way, this is good. Also keep in mind that NO2 levels are a proxy for other types of pollutant too, such as soot from exhausts.

      • That's an interesting question. I'm not seeing an official answer coming up, but there's apparently 32k ZCTAs. Populations of the USA 338M, so approximately 10k people per ZCTA, I'd say.
        Size of ZCTA in land area would vary dramatically, and even population. They're kind of based on postal zip codes, but changed to be more valid for statistical analysis.

    I live not too far from a big bus station here in the UK (Golders Green). About 70% of the bus lines operating from here are now EVs, and the remainder are all hybrid and tend to run on battery when in and around the station. The cab rank outside now mainly has LEVC EREVs which run on battery the vast majority of the time. And increasing amounts of the passing traffic are EVs too. It's substantially less smelly and the air is cleaner than five years ago, and it's also much quieter. Hampstead, St John's Wood and Marylebone are rife with Taycans and other pricey EVs, and again, the air is very obviously cleaner and less stinky, and the roads are much quieter, at least until some tit in a Lambo decides to rev their engines on a high street to impress themselves and their long-suffering partner.

    All the above anecdote, of course, but it matters to me because I am personally experiencing the benefits, as is my family. And its backed up by the air quality monitoring carried out by London's local government. ULEZ has helped massively too.

    A car is an energy generator on wheels. Fossil fuelled cars are a distributed energy generation and pollution system.

    An EV is a battery on wheels. Apart from the tires, that regular cars have too, they don't pollute as they travel.

    When we generate energy in a few places, like power stations, the problems of energy generation are localised and easier to manage than travelling generators.

  • Not burning fossil fuel causes less air polution than burning fossil fuel? How amazing. ...
    Is this some kind of premature April fools thing?

  • Just image what would happen if people didn't use a 3,500lb car to go down the street to buy a gallon of milk, a box of cereal, and toilet paper.
  • Oh, right, tire particulates cause all the smog...

    As opposed to how many tanks of gas a week from ICE vehicles? About 100 lbs for a tank? vs. weight of four tires - about 100 lbs for four tires.

    And y'all claim tires cause more pollution than gas?

  • This is the only good thing about EVs --OTHER people buying them allowing me better air to breathe in the street.

The cost of living hasn't affected its popularity.
