He referred to this article: https://www.theguardian.com/environm...ping-pollution

Also,
...and "Low-grade ship bunker fuel (or fuel oil) has up to 2,000 times the sulphur content of diesel fuel used in US and European automobiles."

You know how people insist that clean diesel doesn't exist?

...but "[t]he shipping industry is responsible for 3% of greenhouse gas emissions" https://www.theguardian.com/sustaina...s-making-waves

Apparently I do not know the right search terms to find out how Canada uses its electricity. All that I find is how much renewable energy they create.

So, cars are a major contributor within the city, but are dwarfed by cargo ships, which are a relatively small contributor compared to other sources.

You're comparing two different classes of compound here. The chart shows percentage CO2 emissions by sector, which the article points out is partially composed of emissions by ships (4% of the overall, or 29% of transportation emissions).

The study reported on found that cargo ships emit as much oxides of sulfur and oxides of nitrogen as 760 million cars. These compounds are reacted with the metals in a catalytic converter in most cars, and not in most (all?) ships.
