The problem with diesel isn't climate. Diesel has lower carbon emissions than gasoline. The problem with diesel is toxic emissions. California is willing to pay more in shipping costs to pay less in healthcare costs.

Yes, it is.

It is not being phased out in trucks in favor of gasoline trucks, so, even if true, that would be irrelevant.

But it’s also not true, diesel releases more CO2 for the same energy than gasoline does. [0]

That article makes the assumption that the ethanol component of finished motor gasoline has net zero carbon emissions.

"So, while diesel fuel contains slightly more carbon (2.68kg CO₂/litre) than petrol (2.31kg CO₂/litre), overall CO₂ emissions of a diesel car tend to be lower. In use, on average, this equates to around 200g CO₂/km for petrol and 120g CO₂/km for diesel."
