EVs linked to real-world reduction in pollution & respiratory problems, new study

Research conducted by the Keck School of Medicine of USC has found a link between the increase in the use of zero-emission vehicles to improved air quality & public health in California. This is said to be one of the first studies which use real-world data to show EVs bring down pollution and respiratory problems.

The new study is said to have analyzed data from a number of ZEVs (zero emission vehicles), ambient NO2 pollution, asthma emergency department visits and population characteristics across 1,238 zip codes in California between 2013 to 2019.

EVs linked to real-world reduction in pollution & respiratory problems, new study-mercedesbenzeqs1.jpg

As per reports, between 2013 - 2019, ZEVs increased from 1.4 to 14.6 per 1000 people, on average, across zip codes in the state. The results showed that within a zip code, an increase of 20 EVs per 1000 people reduced NO2 levels by 0.41 parts per billion and reduced asthma-related emergencies by 3.2%, indicating a positive outcome for both environment & public health.

However, the study also highlighted the EV adoption gap between neighbourhoods with varying educational attainment. Research showed a zip code where only 17% of the population had a bachelor's degree had an annual increase of just 0.70 ZEVs per 1000 people, compared to a zip code where 47% of the population had a bachelor's degree having a higher ZEV adoption rate of 3.6 per 1000 people. This difference further causes disparities in pollution and public health among neighbourhoods.

The findings are said to help policymakers take important decisions regarding the future of transportation. The results of the research provide crucial evidence while creating policies.

Re: EVs linked to real-world reduction in pollution & respiratory problems, new study

Even though the EVs are reducing pollution in the cities, there are still a lot of questions regarding the overall impact on enviroment as long as source of electricity is coal. But what really shines in this study's report is that less people are visiting hospital for respiratory issues and that is definitely a big plus.

Re: EVs linked to real-world reduction in pollution & respiratory problems, new study

It's easy to measure a reduction in pollution where the vehicles are used.
They should go to the mines in Chile where the lithium comes from and do a study there.

Re: EVs linked to real-world reduction in pollution & respiratory problems, new study

I just hope this isn't one of those studies like the one which said that Pfizer vaccine had 100% efficacy!

On a serious note, IMO there's no way EV's can reduce global warming & pollution. Atleast not in the current way we're mining.

We're just shifting the pollution source from the tailpipe to the mine fields!

I don't get the mining argument done here, aren't we mining crude at this moment, which has been devastating on many oceans and destroyed thousands of marine life.

Re: EVs linked to real-world reduction in pollution & respiratory problems, new study

I was happy to see this article, @Rahulnagaraj published few positive EV stories after a series of only negative EV stories, I understand negative stories get more views.

Yet so many comments against EVs, not surprising.

Lithium mines are like salt pans(atleast lithium from chile use this lithium pans), where water evaporates to leave lithium. Water evaporation causes few issues with respect to humidity but nothing close to the pollution levels at a oil drilling site.

Only <10kg of lithium used in an EV compared to 1000s of kg petroleum crude to power one car. Lithium can be recycled from used batteries, can you recycle used petrol?

Oil drilling, shipping, refining, transporting are clean and green activities and battery companies are conspiring against oil to push dirty batteries.

Re: EVs linked to real-world reduction in pollution & respiratory problems, new study

A study focussing on health without touching upon diet and fitness is completely useless.

A casual search makes the study appear as dubious as it indeed is. This study has been conducted by Erika Garcia of Keck Medicine of USC Institute. This instituition has been openly funded by China. Link

Further, this institute is providing "gender-affirming healthcare',which means they castrate boys and men and call them women! This makes it obvious that they don't even know who women are in the first place! A study from such a dubious university can be safely swatted aside as the work of the Chinese battery mafia.

Shipping and Air travel are the sole cause of pollution and as long as they are needed to funnel wealth to china, these environmentalists will never point a finger at them!

One major factor contributing towards inertia against EV adoption is I guess the human tendency to resist change.

There was a time in US (during the beginning or 20th century) when number of EVs outnumbered the total number of IEC based vehicles.

Re: EVs linked to real-world reduction in pollution & respiratory problems, new study

Typical disinformation campaign.

1. Post some irrelevant link - check
2. Post some meme or nonsense screenshot - check
3. Write a typical FUD against EVs, add some chinese masala - check
4. Criticize environmentalists - check

This is how "Hydrogen is future", "Lithium is dirty", "EVs are dirty than ICE" campaigns are pushed.

Re: EVs linked to real-world reduction in pollution & respiratory problems, new study

An individual can't go toe-to-toe with the online propoganda by the EV mafia but, inspite of the dubious studies, it has been clearly understood by all that EV supply relies on the cruel mining processes of Africa, inhuman labor of China(sole supplier of world's EV battery supply) and the increased shipping using most polluting shipping containers with the sole notion of benefitting China.

It's time we ignore the online propaganda and focus on making shipping green, instead of calling for increased shipping pollution.

As opposed to all the “EVs are destroying the environment! They’re EVIL!” Studies which are totally not sponsored by oil companies. Totally legit, unbiased studies right there.

Let’s be honest, they’re not mining that lithium for the benefit of the environment. They’re making money from it. Chile can choose to control their production of lithium to tolerable limits but they won’t. Everything is business. People talk as if oil manufacturing is the cleanest operation in the world. Do we go back in history and look back at the things that happened when oil extraction went wrong? I guess we have a short memory.

There are no angels, but you can choose the lesser evil. Life is never black and white.

The biggest lithium producer is Australia. Funny how nobody mentions them. Because they’re able to extract it properly. And they have more than twice the production of Chile and almost 5x of China. Africa doesn’t even come close.

I am more than happy driving an EV because it’s a cleaner environment for the people around me. If my loved ones have to breathe in less diesel fumes, I’m happy. And I’m genuinely happy to see so much adoption in my city.

China holds 60% of the world's supply of lithium. Link

This is a 'conservative' estimate and requires to be taken with a few buckets of salt. They are the monopoly in EV batteries.

I don’t think they’re talking about reserves. They’re probably talking about refining.

Because here’s the data by the USGS for Lithium sorted by resources:

And by Production:

Also yes they have a high market share in battery manufacturing, even Tata gets its batteries from there. They’re also a monopoly in a million other things. I don’t see how that affects environmental impact of EVs.

Re: EVs linked to real-world reduction in pollution & respiratory problems, new study

The logic is simple. Asthma patients reduce while some other ailment picks up. Did the study look into it? Am sure no. Some stories hardly come out in the right way and we are forced to believe what we read is right. It's just like engineering. You want to increase the mileage, the pick up reduces. You want power, the mileage goes down. There are two sides to the story. Bottom line is - let's not believe either oil or EVs are environment friendly. Whatever the EU states is just about 2% or 3% of the world's traffic. Look at Asia and Africa and produce some stats, it will make more sense.
