Fun little read
While interesting, it's highly misleading. The 15 biggest ship produce more sulfur oxide (and maybe nitrogen oxide) pollution than cars. However, those are localized pollutants, and while bad, in the middle of the ocean they matter less (or at least matter less to people). When it comes to GHG emissions, cars still win by many orders of magnitude. Fun fact, there's a good chance the same is true of lawnmowers. Since they're simple engines with no emissions control they emit a lot of other pollutants that cars produce very little of. Gas engines found in cars have many emissions control mechanisms, and gasoline is highly refined, which mean they are fairly clean, compared with other engines, but they still produce plenty of good old CO2.
