My understanding is that it actually lowered the price of Diesel in most of Europe due to more supply in the system while spiking US diesel.
In Europe the fuel tax is way high.
As best I remember tighter EPA standards were put in place so that the US could pollute less like clean diesel European cars.
Europe had cleaner diesel long before the USA and because almost all of their fuel is imported, they have been paying a huge premium for many years.
Not sure how much of the diesel price increase was due to US exports and how much was due to higher refining cost.
It has been too many years since I researched that information so I am getting hazy on the specifics.
