Europe has “maybe 6 weeks or so (of) jet fuel left,” the head of the International Energy Agency said Thursday in a wide-ranging Associated Press interview, warning of possible flight cancellations “soon” if oil supplies remain blocked by the Iran war.
IEA Executive Director Fatih Birol painted a sobering picture of the global repercussions of what he called “the largest energy crisis we have ever faced,” stemming from the pinch-off of oil, gas and other vital supplies through the Strait of Hormuz.
“In the past there was a group called ‘Dire Straits.’ It’s a dire strait now, and it is going to have major implications for the global economy. And the longer it goes, the worse it will be for the economic growth and inflation around the world,” he said.
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.
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.
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.
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.)
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.

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.
Plot 1 was 2007 to 2022. Plot 2 was 2007 to 2024.
Uhh this is about dieselgate illegally breaking the limits, not what the legal limits were/are.
I added the math to my original comment. France had 984,064 affected vehicles.
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.
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.
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.
