Not trying to dilute the conversation, but this is a different kind of pollution. Differently from CO2, these pollutants do not have the same effect globally: cars polluting cities is way more deadly than a ship polluting in the ocean. To put in perspective, the article cites 2k deaths/year in UK and 87k worldwide because of ship pollution. However, car pollution kills more than double that: 5k/year in the UK [1] and far more worldwide, 200k only in the USA [2].
