> the US as a whole has cleaner-burning fuel than the EU, which for bizarre reasons settled on diesel as their standard even though it's far worse for the air than gasoline. Careful here: the US optimises for low NOx for health reasons while the EU optimises for low CO2 for environmental reasons. See for example https://theconversation.com/fact-check-are-diesel-cars-really-more-polluting-than-petrol-cars-76241 https://theconversation.com/fact-check-are-diesel-cars-reall... (the first website I've found that doesn't look like an all car manufacturers propaganda site) which claims "In use, on average, this equates to around 200g CO₂/km for petrol and 120g CO₂/km for diesel." They even refer to the Kyoto protocol as a reason for the push for Diesel and also point out the issues with optimizing for CO2 only. But still it's not as simple as "Diesels pollute, the EU must be mad".
