How is that related to diesel vs petrol? Why would using petrol be "far worse"?

  Well if you care about CO2 petrol is more than that.

    And if you care about NOx and other pollutants diesel is more than that, which is what the article is about.

      It's about a public health risk. Which needs to be contracted by how many lives it saved. Thats the only way to look at this if you want to assess whether it was a good or bad idea in the first place.
