I remember the episode, I think it was called I

New York, and I recall there was a tribute at the end which referred to 9/11 but I wouldn't call it "tackling" the issue. Carrie just went on about New York being her "man" and that was about it. To me, tackling the issue would have been the characters talking about it, about people they know who were directly affected and lost loved ones and the changes it made to life in the city (increased security everywhere).
I visited New York six years after the attacks and people were still talking about where they were when it happened, you would overhear them in restaurants discussing it, and the heightened security everywhere meant it was impossible to ignore what had happened. The city was in mourning for a long time.
While I get that SATC chose to honour the events in an indirect way, this episode being their "love letter to NY", I think to say that they "tackled" the issue is a bit of a stretch!
