Emissions from everything else are rising fast too. Surely curbing emissions growth from electricity generation will have a much bigger impact.

The articles about SO2 and NOx emissions are clickbait. They compare to cars, which are extremely clean in this respect. In any case, the subject here is climate change and these pollutants are irrelevant. (Strictly speaking, they slightly mitigate warning.)

I’m not saying we should ignore shipping, but I don’t see why it should be anywhere close to first on the list of things to focus on when fighting climate change.
