Answer

probably should be "world-ranking" not work-ranking

vehicles (no intial "c")

1) yes
2) it means that someone (who?) has said these are the toughest emission standards set in in a major world city.  https://en.wikipedia.org/wiki/Global_city as you will see it is a complex subject with London and New York at the top.
