Accidental climate impact study coming soon?

Can we get this map (Paris before and after cycling was pushed) but for the entire atmosphere once the jet fuel runs out?

Paris has to remove the low emission zone so old polluting cars are back in the city. Parliament just approved that.
This is a total disaster, like 2 days ago.... I guess we're going right back to the first map.

After much thought and googling, really that's before and after dieselgate.
NO2 is a notorious byproduct of diesel engines at 10x the rate of gasoline cars. Dieselgate cars emitted 40x the legal amount. You can't quite do this, but roughly that means a dieselgate vehicle emitted 400x the NO2 of a gasoline car. Aka a single dieselgate vehicle was equivalent of 400 gasoline cars.
Now let's get the absolute number of cars. France had 984,064 dieselgate affected vehicles. Paris has about 19% of France's population. Assuming equal ownership that's 186,972 dieselgate affected cars in paris. At 400x the emissions of gasoline cars that's the equivalent of a whopping 74,788,800 gasoline cars.
So replacing the dieselgate affected cars with gasoline cars (apparently the popularity of diesel peaked around then and has been declining since) is the equivalent of removing 74,788,800 - 186,972 = 74,601,828 vehicles off the road in paris alone.
Dieselgate was 2015 so the change between 2020 and 2024 definitely was bikes, seen by how the main car roads are still horrible and emission standards havent been tightened enough to create such a big change. It really is just less cars driven and less space where cars are allowed.

My car actually had a dieselgate recall in 2024. They didn't do them all at once.
It's the same plot, unless you're trying to split hairs between 2022 and 2024. The big change red to yellow/green is dieselgate.
Also, the fix for dieselgate was not isolated to 2015. That shit took years to get the vehicles off the road.
The difference between the plots is quite significant. Also european NOx emission standards for passenger cars have been unchanged since 2014 for diesel and petrol with diesel emissions only being ~33% higher than petrol which means there would definitely not be such a drastic change just from diesel being phased out. Also dieselgate was actually the "Volkswagen emissions scandal" meaning it affected Volkswagen cars and has therefore basically nothing to do with these stats about Paris because the french VW market share is ~7%. Also the thing is that the color of the roads in 2017 is basically the same for all of the roads, but since 2020 there is a clear shift to the big ring road, meaning there wasnt just a reduction but also a clear shift in where the cars drive. Clearly the pollution is highly localized so this change of banning cars from the inner city significantly improved air conditions for everyone but the people living right next to the big roads.
VW was far from the only one cheating emissions, the were just the first to get caught. Other manufacturers have recalled cars too AFAIK.
French VW market share is 7%
Did you also include Audi, Porsche, SEAT, Škoda? Those are also VW brands and use the same engines. There's a few others but those are the ones I know use the diesels.
Plot 1 was 2007 to 2022. Plot 2 was 2007 to 2024.
Also NOx emission standards for cars have been unchanged since 2014 for diesel and petrol.
Uhh this is about dieselgate illegally breaking the limits, not what the legal limits were/are.
basically nothing to do with these stats about Paris
I added the math to my original comment. France had 984,064 affected vehicles.
Uhh this is about dieselgate illegally breaking the limits, not what the legal limits were/are.
Yes and im saying dieselgate is irrelevant because it only involved VW cars which again only makes up for a small percentage of cars in france. VW cars alone wouldnt have been enough to create such a big change by themselves.
France had 984,064 affected vehicles.
Thats around 2.6% of the estimated 38 million cars in france, so not a really important factor when the NOx reduction is something like 70% since 2007.
See my original comment for the math. The effect is staggering.
You havent provided any sources and your claims are nonsense.
NO2 is a notorious byproduct of diesel engines at 10x the rate of gasoline cars. Dieselgate cars emitted 40x the legal amount. You can’t quite do this, but roughly that means a dieselgate vehicle emitted 400x the NO2 of a gasoline car.
This math is just nonsense. As you see from the emission standards, the NOx emissions are only slightly higher for diesel cars. Also the 40x number is about US regulations not european ones. Just find some actual sources for this maybe then come back and reply.
I think your math is confusing people here:
"Dieselgate cars emitted 40x the legal amount."
40x the legal amount FOR DIESEL.
"roughly that means a dieselgate vehicle emitted 400x the NO2 of a gasoline car."
You're arguing that the legal amount for diesel is 10x that of a gasoline car, and by exceeding that 40x, they are more or less 400x a single gasoline car.
Now I don't know if any of that is actually TRUE or not, I'm seeing a lot of the weaselly "up to 40x", not that it was ACTUALLY 40X. It might have been 25x on average, we don't really know. Still awful.
But the piece you're missing is that dieselgate didn't impact ALL diesel vehicles, it was specific to Volkswagen group. So only VW and Audi, and even then, only the TDI models.
Well, first off, VW also includes SEAT, Škoda and Porsche that also use their diesel engines (Porsche no longer does after Dieselgate).
I'm also not sure what you mean by "only the TDI models". They haven't been making naturally aspirated models in decades. They're pretty uncommon these days.
Secondly, VAG was the first to get caught, but many manufacturers were cheating. Including Renault and Citroën, which I imagine might be moderately common in France.
Uh no I'm saying the actual amount is 40x and 10x. Not legal, actual.
And uh no I clearly have the number for specifically dieselgate affected vehicles. (Well 10x is for all diesel if you're thinking of only that. 40x was dieselgate and "France had 984,064 dieselgate affected vehicles.)
This is a good time for the EU to get its shit together on their train networks. Make one central portal for booking trains Europe wide, remove the no fuel tax subsidies and no VAT for airlines and apply them for trains instead, and invest in a network of night trains.
The European Rail Passengers Union recently started and is looking to advocate for solutions to some of these issues.
can we stop calling it iran war and start calling it usa and israels expansionist war?
To be fair, we usually also call it Ukraine war instead of Russo-Ukranian war or just Russian invasion or Russia Expansionist war. Makes it not less wrong, but you need to admit Iran war is a little shorter than your suggestion.
Names with the same or fewer syllables as "Iran War":
- Ego War
- Fossil Farce ^(you could take that a couple different ways hehe)
- Epstein War
- F*ck Kids War
- U! S! [eagle screech that sounds like "A!", except it's not an eagle it's a hawk, because eagles don't screech like that]
- Orange You Glad I Didn't Say Bananuclear? War
Vietnam War
Iraq War
Ukraine War
Iran War
It's just a continuation of the tradition of naming wars where a single country gets invaded by another after that country.
Shorter is better, so how about UIE war? :D
Anyway it was more about calling it iran war makes it sound like iran started it
Technically, it's the "Stop talking about the Trump and Epstein child rape crimes War"
So do people not understand that this is game over? We are in a zombie economy, it may still be walking but in reality it's dead.
Even if the straits open tomorrow, planting season is ending with out the needed fertilizer. Smelters and pot lines for aluminum, iron and glass are going cold. They can't just be restarted, cold idle make them giant bricks and damages them. Pharmaceutical manufacturing is shutting down, and also can't just be restarted. Clean rooms must be re-certified before restart. Similar problems for micro chips production that uses helium from the gulf.
The global economy is having its Wiley E. Coyote moment. The floor is gone, but gravity isn't doing its thing yet.
It's fucking terrifying. And it makes me angry because it was all so avoidable. All the Untied States government had to do was enforce its fucking rules
Brothers in Arms will have to go Down to the Waterline with their Six Blade Knife to save us from Industrial Disease.
Same playbook: starve states until they not only bend the knee but kiss the dirt.
So in six week we will have back out nights that were stolen some years ago by a dubious permission for night flights?
They said this 2 weeks ago. Forever running out, but never getting there
Oh look, it's like the 13th cm0002 spam account that I'm blocking, no exaggeration. I thought I got them all, especially because cm0002 claimed elsewhere that they would only use "a few" to repost and has told several users just that. They make it impossible to block their accounts on purpose. They don't ban evade, they block evade, and when confronted give some line about "promoting smaller instances", even though they never post to their account's home instance.
And before they reply with their bs about only reposting .ML content, they repost shit from all instances. If they truly cared only about reposting .ML content, they wouldn't need almost two dozen accounts to do so.
This is the sixth time this has been posted somewhere on the fediverse, and yet, cm0002 posted it again.
Im not evading user blocks, I provide a listing that's available in my bio. I have told you this and others have as well and you have flat out stated you refuse to take advantage of what tools have been given to you for "reasons".
Additionally, your story about me changes every time someone counters your arguments.
.ML content, they repost shit from all instances.
Nope, you just assume or, perhaps maliciously just conveniently leave that part out, because someone else crossposted after me. Like you did here: https://lemdro.id/comment/22804934
Actual reasons for multiple accounts:
- Promoting smaller instances, because of the volume of my posting it helps makes smaller instances more recognizable
- Making comms on fitting smaller instances (e.g. a programming comm id make on programming.dev)
- Mitigating against the imposter problem
- Better interconnecting smaller instances
Why am I cross-posting .ml content:
I cross-post from .ml to the nearest relevant non-.ml comm to reduce the influence of .ml comms and indirectly, the instance as a whole, to help vitilize non-.ml comms and make it an easier decision for other instance admins to defederate because one key reason I identified that admins don't want to defederate is because .ml still has some very large comms and some active niche comms.
Some highlights from the link:

And so so much documentation on clear heavy handed censorship and bias also on the link. So much I can't even put them all here because this comment would be really long.
I believe the behavior of its admins (the main admins are Lemmy devs) does harm to the overall growth of the Lemmy-verse and maybe even the Thrediverse (since Lemmy kinda kicked off the Thrediverse) because of its association with the devs of Lemmy and their insistence to use .ml as their personal political platform to spread harmful propaganda
On the outside, bringing up Lemmy frequently leads to comments like "Lemmy? Isn't that the place with a bunch of tankies?" Or "Tried Lemmy, but found it full of pro Russia crap so I left". The best way forward from that I see is to either widely defederate from .ml like the rest of the Triad, or pressure them to put a fair and unbiased as possible admin team.
crosspost
You don't know the meaning of the word. And your history is full of reposts from several instances. Stop lying.
Still love the bullshit story of "promoting small instances" instead of evading blocks. Keep telling yourself that.
Hi again my downvote trolling friend!
And your history is full of reposts from several instances
Then you should be able to provide receipts easily then? So where?
Love that you cherry pick all of your responses. Downvoting a block evader isn't trolling. Not to mention you have deleted and reposted to avoid a downvote before. Seems like someone is still stuck in reddit world the way you care about votes.
I am not wasting my time copypasting a bunch of crap when anyone can click on your history and see the same articles and posts they've already seen multiple times in their feeds.
Lol I've seen your lemvote history, you downvote anyone and everyone serially who you deem "posts too much" lmao
So you've just made up a bunch of stuff and refuse to provide receipts on any of it. Got it 👍
Not to mention you have deleted and reposted to avoid a downvote before.
Troll protection against a known downvote troll, employed on tiny comms only, it's not necessary anywhere else because your ability to push down posts is diluted
Well said. And look, thrre they are with their bullshit answer/excuses, right on queue.
Yep, it's classic. They might as well be a bot, their behavior is very predicitible. It's not even worth ever replying to them, they use canned responses and never change their behavior for the better.
Oh, and they always make sure to downvote anyone calling them out, naturally. Luckily I can't see them as my instance disables downvotes, but I'm sure my comment has at least one downvote (and it'll be from them).
Nah lol all my crossposts are done by my own hands lol

Im not really sure what mesh networking has to do with GOS lol but either way, I can't really recommend much as I haven't jumped into mesh networking (yet)
Then maybe, just maybe, we should start canceling short distance flights?
Would also be a little bit less CO2 pumped out for a while.
I don't know what's "short distance" for you, but a flight from Zagreb to Amsterdam takes about 2 hours.
Using public transportation on the same route is 20+ hours at best and you need to switch between bus and train four times. Driving is 10+ hours.
Maybe, just maybe, we should stop immediately providing kerosine to private jets first? And droping subsidies for jet fuel and financing public transport instead?
nah suspend all flight, no one flies until the train tracks are built and optimized.
And no EU official will even protest US actions, because they fear Trump will leave Nato.
because they fear Trump will leave Nato
which would be the best outcome for europe
